A system for forming and wrapping a plurality of stacks of sheet-like product is provided. The system includes a stack aligner for squaring up leading and trailing ends of the stack as well as sides of the stacks is provided. The stack aligner is also configured for controlling the position of the stacks along the stack travel path such that the stacks exit the stack aligner with tight positional tolerances for being fed to the stack wrapping arrangement.

An interfolder separator apparatus and method utilize a pair of count fingers that are movable longitudinally along and transversely to a stream of folded sheets, for temporarily supporting each successive pack formed by the separator and then releasing each successive pack when partly completed to alternating build fingers, so that the operation of separating successive packs from one another is performed separately from the operations of completing the build of each pack and transporting the completed packs to downstream operations. The count fingers may be mounted to pivot about axes that are movable longitudinally along and transversely to the stream of sheets. A first or last panel of the completed pack may also be folded back partly upon itself, after the partly completed pack is released by the count fingers. Some or all of the fingers may be spring loaded and automatically resettable for clearing jams.

A flexographic printing apparatus and method utilize a support platform attached to a printer frame and four bearing support carriages attached to the support platform for operatively supporting opposite ends of a plate roll and an anilox roll. One plate roll carriage and one anilox roll carriage are operatively attached to the support platform along each opposite side of the support platform by a common linear guide arrangement. The plate roll carriages are positioned along the linear guide arrangements by two plate roll linear positioners operatively attached between the support plate. The anilox carriages are positioned along the linear guide arrangements with respect to the plate roll carriages by a pair of anilox roll linear positioners operatively attached between the plate roll and anilox roll carriages. The support platform is also transversely movable with respect to the printer frame for lateral registration.

A web processing roll for handling a web of material using vacuum is provided. The web processing roll includes a roll body. The roll body defines an outer periphery against which the web of material is held. The roll body defines a vacuum passage. At least one first vacuum hole fluidly connects to the vacuum passage provides vacuum proximate the outer periphery of the roll body to hold the web of material against the outer periphery with vacuum supplied to the at least one first vacuum hole by the vacuum passage. A first flow path of the vacuum hole extends at a first angle that is non-perpendicular to the rotational axis and is directed, at least in part, axially toward one of the first and second ends at the first outlet end of the at least one first vacuum hole.

A log accumulator comprising a plurality of buckets, a feed arrangement and a transport system and methods are provided. The feed arrangement loads logs onto the buckets. The transport system transports the buckets past the feed arrangement for loading of the buckets. The transport system and the feed arrangement are configured to maintain the feed arrangement in a fixed relative position with one of the buckets for an extended period of time while the feed arrangement loads the one of the buckets. The accumulator may include an unload arrangement that operates to unload logs in substantially the same manner as the feed arrangement.

An apparatus and method are provided, for alternatively producing either small or bulk packs of napkins from a stack of folded napkins produced by one folding machine, through use of a pack dispatching arrangement having an inlet, a small pack transfer station and a bulk pack transfer station, and configured for operation in a small pack mode for dispatching a stream of spaced apart small packs of folded sheets separated from the stack of folded sheets, and received at an inlet of the pack dispatching arrangement, to the small pack transfer station, and alternatively operable in a bulk pack mode for dispatching a stream of spaced apart bulk packs of folded sheets separated from the stack of folded sheets, and received at an inlet of the pack dispatching arrangement, to the bulk pack transfer station.

An apparatus and method for moving stacks of product discharged from a stacking device. The apparatus includes a first conveyor movable at a first speed and a second conveyor movable at a second speed. The first conveyor includes an upstream end adjacent to the stacking device. The first conveyor is positioned to receive product from the stacking device. The second conveyor includes an upstream end adjacent to the stacking device. The second conveyor is positioned to receive product from the stacking device. The running speed of the first conveyor is faster than the running speed of the second conveyor to move stacks of product on the first conveyor away from the stacking device at a faster speed than stacks of product on the second conveyor.
摘要:
Apparatus for separating two rolls of paper which are interconnected end-to-end, is characterized by a pair of arms pivotally connected at their upper ends and carrying inwardly facing wedges at their lower ends. The arms are advantageously mounted on wheels to facilitate transport of the same, and a hydraulic cylinder extends between the arms intermediate the pivotal connection and wedges. To separate two interconnected paper rolls lying on a floor, the apparatus is positioned to straddle the rolls with inner edges of the wedges aligned on opposite sides of the rolls with the juncture therebetween, whereupon the hydraulic cylinder is actuated to pull the arms together and move the wedges into the juncture to forcefully separate the rolls one from the other.
