STRIP STEEL DANCE MEASURER

The invention concerns a strip steel dance measurer with a saw tooth-like trained measurer sheet, whose teeth are pyramid-shaped. A such Bandstahlstan more nesser is for example well-known from the US-PS Nr.3, 260.159. The pyramid-shaped teeth exhibit four flanks, which lie symmetrically for the centre plane of the measurer, so that both the points of the teeth and two flanks limiting edges with the centre plane collapsing. Furthermore a Bandstahlstanmnesser with asymmetrical teeth is well-known from the US-PS Nr.3, 170.358. The knife edge is only from a side angesch! it iffen which has as a consequence that all tips of a tooth in the level of a measurer side preserving. Two teeth profiles coincide thereby with the two lo sides of the measurer, while two further teeth profiles are diagonally of a side to the other side of the measurer arranged. This brings transverse forces with itself, which affect the stability and durability of the measurer unfavorably in the enterprise. Finally is from the FR-PS Nr.1.420.429 to the strip steel dance measurer in accordance with the US-PS Nr.3, 170.358 agreeing identical strip steel dance measurer before well-known. IS of the invention is the basis the task, a strip steel dance measurer to create, smaller operating pressures required than and a larger stability possesses the well-known measurers than this. For the solution of this task the invention sees that the Messerbtatt exhibits itself additionally to the teeth along the teeth extending, chamfered surfaces, whereby the teeth profiles within the range of the chamfered surfaces end. By the additional chamfers a knife edge with teeth is created, whose the tip of a tooth directly neighbouring teethe-hurry very sharply and is nevertheless relatively strong. These teethe-hurry possesses the form of a small more dreioder quadripartite pyramid and changes then only very slowly and schmählich into the actual Zahnfuß and/or into the normal transverse longing CCIT of the strip steel dance measurer. The tooth receives thereby a long, slim shape, which lends good gumption characteristics as well as high s a stability to it. A further advantage results in sees from it that the additional, chamfered surfaces on both sides of the Bandstah] stanzmessers is intended. Hiedurch is reached that at the measurer no or only very small transverse forces arise. In accordance with a preferential execution form plans the invention that the point of each tooth neighbouring teethe-hurry, as actually admits the form of of a quadripartite pyramid possesses that two edges running to the point of each pyramid-shaped Zahntefls lie approximately in the measurer centre plane and are designed as Schneid_kanten and preferably pointed angles include with one another and that the level lying from the point of pyramideuförmigen teething ILS outward in one perpendicularly to the measurer level] up-end, a pointed angle including with one another both 3s other edges at the chamfered surfaces of the measurer sheet end that the angle included from these edges is larger than the angle, that the two chamfered surfaces with one another form and that the teeth profiles further as those Edges into the range of the chamfered surfaces are enough and together-pushing end there. The teeth of this Bandstahlstanmnessers exhibit only in the proximity of their points four pyramid-shaped arranged teeth profiles, while they possess six teeth profiles within the range of the Zahnfußes, whereby the flanks outgoing from the tip of a tooth are present also there. In accordance with a further execution form it is suggested that the point of each tooth neighbouring teethe-hurry n see on well-known way the form of a three-lateral pyramid possesses, whose is arranged a flank on the one side the measurer sheet and attaches to the one chamfered surface 4s and their two other flanks on the other side measuringinherit] attes to lie and together-pushing a common, actually well-known, transverse to the longitudinal direction of the measurer sheet running edge to form, which ends at the other chamfered surface of the YIesserblattes and which together with the flank which is on the other side of the measurer sheet an angle includes, which is larger than both surfaces chamfered of the included angle that furthermore the two Flanks of the surface chamfered from the point far into so the range are enough as the edge and that of the points the outgoing, from which off center and diagonally for the longitudinal direction of the measurer sheet is appropriate for a flank with the two other flanks formed cutting edges. Nr.359969 defiance of the easily asymmetrical shape of the teeth are their points in the centre plane of the Bandstahlstanmnessers. Existing asymmetry is only very small and does not become not unfavorably apparent in the field use. The advantage of asymmetry exists in the simple production, because the teeth must be ground in into the strip steel dance measurer only from its flat side. Both with the manufacturing and when regrinding the necessary work expended is smaller from there as with the Bandstahlstanmnesser with quadripartite-pyramid-shaped teeth. The invention is more near described below on the basis the two remark examples, which are represented in the designs. Show: Fig. 1 a side view of a strip steel dance measurer according to invention with a neighbouring to the tips of a tooth teethe-hurry in form of a quadripartite pyramid, Fig.2 a cutaway view along the line II-II in Fig.1, Fig.3 an opinion of a further remark example with a neighbouring to the tips of a tooth teethe-hurry in form of a three-lateral pyramid, Fig.4 a further opinion of the remark example represented in Fig.3, Fig.5 a cut along the line V-V in Fig.4 and Fig.6 a axonometrische representation of the execution form in accordance with the Fig. 1 and 2. 1 in Fig.1, 2 and 6 represented strip steel dance measurers --1-- consists of a measurer sheet --2-- with chamfered surfaces --4 and 5-- and a saw tooth-like trained knife edge --3--. Within the range of the chamfered surfaces --4 and 5-- are with points --9-- provided teeth --8--, of them the points --9-- neighbouring Zahntefl --10-- the form of a quadripartite pyramid possesses. Of the points --9-- outgoing edges --! 1 and 12-- serve as cutting edges and lie in a line with the points --9--, so that a gumption line running straight-lined in the longitudinal direction of the measurer sheet is creative. The two other edges running transverse to the cutting edges --13 and 14-- quadripartite, pyramid-shaped teething ILS --10-- extend from the points --9-- to the chamfered surfaces --4 and/or 5-- and end at these. , As in particular from Fig.2 comes out, that is from the two edges --13 and 14-- enclosed angles gr/it as the angles, that the chamfered surfaces --4 and 5-- include. The teeth --8-- point teeth profiles --15 and 16-- up, and also the chamfered surfaces --4 and 5-- on the two sides of the measurer sheet --2-- serve as teeth profiles. The flanks --15 and 16-- extend from the points --9-- further away as the cutting edges --11 and 12-- and/or transverse to these arranged edges --13 and 14--. Into the Fig.3 to 5 a further remark example is represented, to its knife edge --3a-- Teeth --8a-- , of them exhibits the tips of a tooth --9a-- neighbouring teethe-hurry --10a-- the form of a three-lateral pyramid possesses. A teeth profile --17-- pyramid-shaped teething ILS --10a-- closes directly to a chamfered surface --4a-- the measurer sheet --2a-- on. The two other teeth profiles --18 and 19-- point themselves a common, transverse to the longitudinal direction of the measurer sheet --2a-- extending edge --20-- up and end on the one hand at the flank --17-- and on the other hand at a chamfered surface --5a-- on that the surface --4a-- opposite side of the measurer sheet --2a--. Of the flanks --17-- as well as --18 and 19-- together formed edges --21 and 22-- run of the points --9a-- winkelig to the longitudinal direction of the measurer sheet --2a-- and serve as cutting edges. Furthermore the Fig.1 and 2 show the strip steel dance measurers --1-- together with punching property --25--, that on one of an edition --27-- carried punching document --26-- lies. When splitting the punching property --25-- that penetrates strip steel dance measurers --1-- with its teeth --8-- also something into the punching document --26-- , which can consist of hard rubber, synthetic plastics or similar materials. In particular it is also possible to use as punching document a material which is even softer than the punching property, there the Bandstahlstanzraesser according to invention --1-- only exercises a relatively small punching printing on the punching property and thus the document, acting in vertical direction. Due to the horizontal arranged printing component finally satisfying Stanzergebnlsse can be obtained also with plastics such as polystyrene, synthetic hard foams etc., what was only conditionally reached so far because of the difficulties arising with Anstanzen.
