The fig. 20 shows, in elevation and to larger scale, a portion of the drive chain notebooks and the rail for this chain, as shown in fig. 16.

On the fig. 1 to 10 is designated by 10 the frame of a machine for the manufacture of cigarette paper forms and which has. to its upper position, a table or platform 11. On the table 11 is mounted a suitable entrainment device 12, in particular of a traction drive and comprising suitable means for advancing a number of superimposed strips parallel and cigarette paper 13, of indeterminate length and surrounded by a cover 14 also of indeterminate length. The assembly is designated by the reference 15. The device driver 12 is able to actuate and to drive the assembly 15 by a distraction effect to the left of the Figure 1 and in cooperation with a cutter signature 16 comprising, amongst others, a knife 17 to alternating vertical movement. The device driver 12 is adapted to controlling the total 15 successively at points spaced apart to avoid the deformation or the offset of the cover. The knife 17 is moved alternately in synchronism with the entrainment device 12 but this arrangement is not shown in detail on the fig. 1 to 10 and will be described more explicitly below about the fig. 11 to 20.

After been cut of the assembly 15, the signatures of sheets to separate 19 cigarettes are fed by a plane ' inclined 20 on a belt 21 and introduced into a collecting device 22 from which they can be removed at the desired time and in any appropriate manner. The details of a drive device and a collector device are not shown in the fig. 1 to 10 and an advantageous embodiment will be de-criteria about the fig. 11 to 20.

In front of the drive device 12, i.e. to the right of Figure 1 and on the table 11 supports are fixed 23, on which are secured shafts 24, 25, 26 and 27 arranged to form an open frame. Said shafts 24, 25, 26 and 27 extend to the right of Figure 1 and the outer ends of the shafts 25 and 26 are supported by a post 28.

The shafts 24, 25, 26 and 27 carry, adjustably and in the vicinity of their end right, a frame consisting of bars 29 and 30 interconnected by crosspieces parallel 31 and 32. The frame forms a support for the free ends of the shafts 24 and 27. On the webs 31 and 32 can slide, to approximate or deviate from the bars 29 and 30, a bent part 33 in which there is a channel 34. The channel 34 has a width substantially equal to the width of the strip 14 for forming the cover. On the rod 29 can rotate a shaft 35, whose inner end is threaded and screwed into a threaded hole in the curved piece 33. The outer end of the shaft 35 carries a bevel pinion 36 and a flywheel 37. The bevel wheel 36 meshes with a bevel gear 38 keyed to one end of the shaft 39 which, itself, rests in suitable bearings and which leads to the vicinity of the belt 21 which causes the strips of cigarette paper. The end of the shaft 39 carries a flywheel 40 by which the monitoring of the machine, placed in proximity of the belt 21, can rotate the shaft 39. 39 The rotation of the shaft results in translational movement of the bent part 33 to the sleepers 31 and 32 and causes a lateral movement of the strip 14 with respect to the direction of its Employees, enclose.

On the shafts 25 and 26 is mounted, in a manner adjustable, a bar 41 extending between said shafts. On the upper side of said bar and extending upwardly are fixed two parallel uprights 42 and 43. The posts 42 and 43 support between their ends a horizontal plate 44. On the upper face of this plate rests a guide 45 for several superposed strips 13 of cigarette paper. The upper ends of the legs 42 and 43 are threaded and thereon is mounted, in a manner and by adjustable nuts 46, a horizontal plate 47.

On the upper side of the horizontal plate 47 is attached, by a bolt 48, a U-shaped component and of which the portion 49 has a elongated groove 50 to enable adjustment workpiece longitudinal U-shaped with respect to the guide 45. The edges of the workpiece 51 extend downward in the guide 45 and their lower ends bear forks 52 whose limbs have a distance corresponding approximately to the width of the strips of cigarette paper 13.

At the supports 23 is mounted a horizontal rail 5 53 on which moves the set 15. The rail 53 terminates, at its right end, to the upper face of the plate 44. Near the right end of the rail 53 and partly below 1 o the discharge end of the 4.5 guide, is attached a device combined guide and folding 54 for the cover strip 14. On one end of the rail 53, and to the outlet end, of the combined device guide i5 and folding 54, is mounted a roller horizontal groove 55 for folding the corresponding edge 56 of the cover strip 14 in the opposite edge 57 thereof. The arrangement as described is 2 o shown clearly on the fig. 4 and 5 and on these figures see also between the folding device 54 and the drive device 12, auxiliary folding members 58 and 59 permanently 26 which complete the folding of the cover on the plurality of strips 13 of cigarette paper.

Note that the cover strip 14 is fed to the drive device 12 at the same speed that the strips laid super -3o of the paper guide 45 and of the device 54 to bend and guide the cover and by the positions that these members occupy relative to each other, the web 14 is folded onto the plurality of strips 13 without coming 3,5 actually in contact therewith during most of the bending operation. Only after the preliminary bending has occurred positively that the cover strip 4o receives its final shape by pressing. Thus there is no tendency or possibility that the strips of cigarette paper 13 are subjected to a deformation, an offset or distortion, as has been verified by field trials of 45 the invention.

Means are added to the paper web 14 for the cover, to adjust the tension of the blade when it passes through the device 54 for guiding and folding. 5 o The means includes a elastic tension which acts on a control device located at a short distance from the location of the monitoring of the machine. As shown and as preferred, these control means comprise a visual indicator to alert the monitoring person 55 the degree of tension. The device is shown clearly on the fig. 1 and 2, on which images there is shown an arm 60 of a pair of arms attached to the table 11 or piece therewith. The Go arm 60 terminate in open bearings 61 in which is rotatable a shaft 62 on which is fixed a brake pulley 63.

The roll of the web 14, for forming the cover, is engaged on the shaft 05,62 and the tape passes over the short piece 33, as described above. On one of the arms 60 is attached, by a bolt 64, one end of a brake band 65, provided with brake blocks 66 while the other end of the band 65[...] is connected to one end of a coil spring 67. The other end of the spring is attached to a cable 68, passing under an idler pulley 69 and then to a dancer pulley 70. The free end of the cable is--5 [...] attacks to an end of a shaft 71. This is slidable in a room 72 mounted on the table and on the shaft 71 is formed a rack 73. The rack meshes with a worm wheel 74, whose axis So carries a needle 75 cooperating with a marking disk 76.

Compared to the workpiece 72 can rotate a shaft 77 carrying a worm wheel and a crank 78 79 85 for adjusting the position of said shaft. By rotating the worm wheel 74, the tension of the helical spring 67 and the voltage of the cover strip 14 can be

o The adjusted. [...] has not shown the power source of the paper webs 13 and the means for adjusting the tension of the strips.

When the machine for making signatures operates, the monitoring is typically placed at the discharge end of the machine, typically near the feed belt 21, so that the control devices or regulating devices 18,40 and 79 easily accessible. Separated When the signatures 19 are billed to the inclined plane 20, they fall into the collecting device 22 and come ae placing vertically next to one another on their edge. The manifold 22 has a straight edge 22", according to its side face which is on the side of the 5 monitoring pom allow it to exactly tested the line of intersection of the individual sections with respect to the indications marked on the cover. Using this indication can adjust the monitoring 1 o the operation of the cutting machine to cause the cut line in a correct position with respect to said indications. Indications, such as those shown in fig. 9, advantageously comprise a score line " 19^{1 that can be used} together with the edge 22^{has verification}.

The plurality of superimposed strips 13 cigarette paper and neckband [...] -2" lf Opening are driven, from their respective power sources, across of the machine by the drive device 12. The advance is, preferably, in a continuous manner but can also 5 be intermittently, by providing an average speed for the strips 13 which is in [...] equal to the thickness of the web 14. The tension of the web 14 is controlled, as desired, by the surveil -3 o-linking of the machine as described above. Furthermore, by operating a suitable way the steering wheel 40, it can suitably adjusting the lateral position of the band 14 with respect to the strips 13. The 35 guide means 45 direct the set of bands 13 without deforming them and these strips leave these means 54 lice enter centrally in the combined device for guiding and folding the strip cover 14 4o well as it moves axially in said device.

The cover strip 14 enters the device combined guide and folding below all the 13 h 5 strips of cigarette paper and it is then subjected to bending. The shape and dimensions of the guide device and the folding 54 are such that the shape and dimensions of the band 14 are adapted to the section 5o component paper webs 13 and that it data before the web 14 comes [...] in contact with these strips 13.

This eliminates the disadvantages of known machines of this type in which 5,5 the cover strip is folded by being in contact with the webs of paper, resulting in an offset or deformation of individual strips and therefore defective signatures and appearance irregular. 6o Therefore, the machine set according to the invention makes it possible to produce economically books cigarette paper for which several superposed sheets of cigarette paper 65 are surrounded or enveloped by a covering disposed symmetrically about said sheets without an offset or distortion of the cover or individual sheets of the booklet. [...] Generally, beneficial results are obtained indicated above, and further on which there is no further insist [...] by the important features of the invention, in particular by [...] 3 the means for simultaneously advancing both the paper webs for forming the leaflets of the signature and the cover strip therefor, by the means for prefolding 8o the cover strip into the shape and dimensions to surround, satisfactorily, said paper strips and before the cover comes into contact with said strips. Furthermore, 85 is provided a new approach to provide an adjustable tension between the cover strip and lateral movement thereof with respect to the strips of paper during advancement 90 simultaneously the cover and paper webs.

On the fig. 10 to 20 the frame 110 of the drawing door, as for example, a table 111 with drive device 112 to advance the assembly 115 g 5 consisting of superimposed strips parallel and cigarette paper 113, of indeterminate length and by crumb cover strip 114, also of indeterminate length.

The strips of cigarette paper 113 from a source (not shown) set to right of the fig. 10 while the cover strip 114 is debited by a roller 116, rotatable by a shaft 117 seated in bearings 118. Adequate means are provided to act the voltage required on the paper web 113 and 114 on the cover strip, the tensioning means for the cigarette paper 113 is not shown while those for the cover strip are designated generally by the reference 119. A mechanism for adjusting the tensioning means is designated by the reference 120 and is established near the position occupied by the monitoring of the machine.

The cover 114 is folded around all the paper 113 by a device 121 with guide means 122 strip 113.

The drive device 112 is adapted for driving and to advance the assembly 115, by means of a suitable pulling to the left of the fig. 10 in cooperation with a device for cutting the signatures 123.

The cutting device 123 is established between parallel, spaced apart plates 124,125 and has shafts 126 and 127, which can rotate in the plates 124 and 125 are parallel to and spaced apart from one another. The shaft 1-27 oscillates in its bearings and on the shaft is fixed a frame 128 which extends upwardly between the plates 123 and 124 and on the upper part of the frame 128 is fixed a plate 127. On the shaft 126 and side of the plates 123 and 124 are provided eccentric 130 and thereon are engaged eccentric rings 131 to each of which is fixed a rod or a shaft 132. The shafts 132 move to and fro in holes 133 formed in the frame 128 and are connected to a beam 134 carrying a guillotine knife 135 cooperating with the plate 129. When the shaft 126 rotates, the guillotine knife 135 moves in a reciprocating motion relative to the plate 129 for cutting a signature cigarette paper 136 of the assembly 115. At the same time the frame 128 swings on the shaft 127 so that an oscillating movement is given to the plate 129 and the knife 135, in synchronism with the speed of advancing of the combination 115 such that movement of travel of the assembly 115 is not hindered.

The cutter 123, as well as the entrainment device 112 are actuated by a transmission 137, mounted on a box 138 mounted to the plate 123. The input shaft 139 137 of the transmission carries a pulley over which passes a belt 140 141 driven from any suitable power source (not shown). On the transmission output shaft 137 is mounted a bevel gear 142 meshes with a gear wheel 143 fastened to the lower end of a shaft rotating in bearings 144 145 123 fixed to the plates. On the shaft 144 is freely mounted a frame 146 between the brackets 145. On the lower end of the frame 146 is mounted a worm wheel 147 crumb meshing with worm drive 148, keyed onto the shaft 149. The shaft rotates freely with respect to the plates 123,124 and bears at one end a flywheel 150 by which to rotate the shaft 149. On the shaft 144, so as to rotate therewith between the confines of the frame 146, is mounted a bevel gear 151 meshing with the gears 152 and 153 which are free to rotate within the frame 146.

The bevel gears 152 and 153 engaged with a pinion gear 154 fixed to a sleeve 155 which can be pivoted relative to the frame and to one of the brackets 146 145. The sleeve 155 carries at its upper end a bevel gear 156, which meshes with a toothed wheel 157 attached to one end of the shaft 126.

The transmission 137 has, at its output, a shaft 158 which actuates the drive device 112. There is a determined relationship between the speed of travel of the assembly 115, determined by the feed device 112 and the reciprocating movement of the knife 135. The latter is actuated to cut the signatures 136 of the assembly 115 so that the indications, trademark or 159 drawings that must have the signatures are arranged symmetrically with respect thereto. As a result of the voltage, moisture or other reasons, the indications 159 are no longer symmetrical with respect to the signature 136 and the monitoring by rotating the shaft 149 can change when the knife 135 operates in accordance with the progress of the assembly 115, thereby restoring the symmetry of the indications with respect to specification 136.

The transmission includes also, to the output, a shaft 160 on which is fixed a worm wheel 161 meshing with a worm 162 wedged on a shaft 163 flywheel 163^{has readily accessible from the} monitoring and to rotate the shaft 163, to changing the gear ratio between the shafts 139 and 158, which is another means for altering the manner in which the knife 135 and the drive device 112 cooperate.

Parallel shafts 164 and 165 are freely rotatable in bearings provided in the plates 124,125, these shafts carrying respective gears 166 and 167 on which an endless chain 168. This door on one side a plurality of parallel bars 169, rubber or other suitable material, arranged transversely relative to the chain 168, as clearly visible on the fig. 19 and 20.

On bars 170,. established between the plates 124 and 125, rests a curved rail 171 and on which is guided the working part of the chain 168. A a shaft 172, which extends between the plates 124 and 125, is articulated an arm 173 carrying a stub shaft 174 on which rotates a toothed wheel 175 meshing with a portion of the string 168. A the shaft 173 is attached an end of a coiled spring 176, whose other end is [...] to a lug 177 provided on the table 111. The spring 176 168 pull the chain during its passage on the rail 171.

The chain 168 is driven by a shaft 164 and for this purpose is provided on the chain a toothed wheel 178, forming part of a gear train driven by a gear 179 keyed to the shaft 126. The speed of advance of the chain 168 is therefore in constant relation with the speed of operation of the knife 135 and the drive device 112.

On bars 180, secured to the plates 124 and 125, are mounted envelopes 181 and 182, which extend relatively lightweight i downwardly as shown in the Figure 16 and 17, and on the lower ends of the envelope is fixed a box or hopper -183 to receive the signatures 136 cigarette paper year as they are (brought by the chain 168. From time to time these signatures are removed by the guardian of the machine.

For providing assurance that the signatures 136 are held in engagement with the (168 chain, passing over the rail 171, there is provided means that not only provide this capacity, but, further, act on the rear end of a 136 away from the line of advancement of < _AOE296A0AO> the front end of the next ply 136.

The means specified above essentially comprising a endless belt arranged as follows. Near the shaft 165 and parallel thereto is provided a shaft 184. The shells 181 and 182 carry bearings for the shaft 184, as clearly visible in fig. 17. On this shaft is mounted a pulley and 189 near g the shaft 164 is provided a shaft 185 which is free to rotate in a bearing of the plate 125. 185 To this shaft is articulated one end of an arm 186 on the outside of which is fixed a shaft 187 g on which is freely rotatable a pulley 188. On the pulleys 188 and 189 passes an endless belt 190 which also passes over an idler pulley 191 carried by the envelopes 181 and 182. The pulley 188 When g occupies the position shown in fig. 16, it is evident that the portion of the belt that is adjacent to the chain 168 is merged with the path of the chain and 168 that if a sufficient voltage acts on the [...][...] 190, the signatures 136 are held firmly in contact with the chain and are positively fed from the knife 135 to the discharge location adjacent to the gear 167. ic To apply the voltage required on the belt 190 and also for carrying out operative relationship with the toothed chain 168, the following arrangement.
