A transport apparatus for handling rows of units of multi-ply material such as rolls of bathroom tissue or paper toweling and stacks of folding facial tissue or toweling includes a pair of movable shuttles which can be moved together to provide a bridge for conveying the units over an opening and which can be moved apart to provide a gap so that trim pieces or selected units can fall through the opening. When the shuttles are moved to an upstream position, the shuttles bridge the opening, and units can be moved over the shuttles and over the opening. When a trim piece or selected unit is positioned just upstream of the downstream shuttle, the downstream shuttle is moved in a downstream direction away from the upstream shuttle to provide a gap between the shuttles so that the trim piece or selected unit falls through the gap and the opening. The upstream shuttle can then be moved in a downstream direction toward the downstream shuttle to close the gap.

FOLDING MACHINE, PARTICULARLY FOR THE MANUFACTURE OF PAPER TOWELS

Apparatus for cutting a stack of superimposed continuous material strips

Assembly of textile plies by compression produced along spaced lines - by passage through the nip of a bevelled rollr pair

Several plies of textile web are advanced together through the nip of a pair of rollers the upper one of which pref. has a periphery with bevelled edges and the lower one of which pref. has a correspondingly shaped peripheral groove into which the periphery of the upper roller seats. The plies are compressed together along two space lines between the respective bevelled edges of the upper roller and associated bevelled sides of the groove in the lower roller. The method is used for securing together plies of tissue paper. The plies can be secured together successfully using a low compression force, thereby reducing wear of the rollers.

Roll winding machine

The high output low maintenance winding machine uses a peripheral drive with entry rollers. The rollers feed the paper strip over the first and second driven cradle-forming rollers (21,22) rotating at a set speed. A roll-former (C) fits between the latter rollers, and is held in this position by a displaceable follower (23) in contact with the roll. Grooves in the second roller are used to mount endless belts (25) travelling at a speed less than the set speed. The belts, together with other equipment are used to feed a succession of formers through the gap between the cradle forming rollers. Ancillary equipment may perforate the strip and may cut it to length. A coordinated pivoting arm (43) with an adhesive dispensing head (32) is used to displace formers taken from a magazine (47) by an oscillating arm (50).

In apparatus for delivering stacks 38 of generally rectangular web units comprising a generally horizontally extending conveyer 37 and first and second stack-supporting fingers 42 and 41 respectively, means for reciprocating the fingers 42 whereby a stack is adapted to be transferred from the first stack supporting fingers to the conveyer, means for orbiting the fingers 41 in a generally vertical plane to a position below the fingers 42 whereby a partial stack is transferable from the fingers 41 to the supporting fingers 42, means are provided for transferring a stack of units from the fingers 42 to the conveyer. The means include a plurality of horizontally spaced apart table fingers 43 arranged to receive a unit stack from the fingers 42 as they pass downwardly between the table fingers 43, and a pusher mechanism equipped with a plurality of upstanding pusher elements 44 arranged to pass between the table fingers to horizontally move a unit stack from the latter. The stacks 38 are each formed of fifty 11-ply units. Each unit is delivered by a conveyer 59 (Fig. 4) to gripping mechanism 40 by which it is turned over (as at 39) and deposited on the fingers 42. The tips of fingers 41 are inserted into the stack at such a height as to isolate below themselves a stack 38 of the required number of units. The fingers 42 are then lowered so as to deposit the stack 38 on the fixed table fingers 43. Pushers 44 are then reciprocated so as to displace the stack 38 on to the conveyer 45. Meanwhile the fingers 42 rise and receive the growing stack on the fingers 41. The latter are then withdrawn and orbit so as to be able to be inserted into the stack as before, thereby defining the correct number of units in the stack thereby isolated on the fingers 42. The fingers 41 have a to and fro reciprocating component of movement ...
