A drum arranged for reeling and dividing an elongate web of sheet material to produce discrete stacks of web portions is provided. The drum includes a series of faces forming a web-receiving loop that extends around a central axis of the drum, each face of the drum being defined by a respective drum segment that is configured to support a respective stack of web portions of a web reeled onto the web-receiving loop. The drum segments are movable to enable the web-receiving loop to expand to increase tension in a web reeled onto the web-receiving loop to divide the elongate web into discrete stacks.

The provided containers (100, 200) and methods provide for gravitational alignment of a plurality of stacked articles (120), in which at least two edges (140, 142) of each article align along inner walls (108, 114, 208, 214) of a respective container. The aligning walls of the container are provided with low-friction surfaces to facilitate sliding and alignment of the articles. By aligning the stack of articles along two edges, the articles can be registered relative to not only each other but the container itself, thereby facilitating loading, unloading, and conversion of articles in the stack. Optionally, a compressible layer (147) opposing one or both of the aligning walls conforms and distributes stress along the non-aligning edges, thereby preserving registration of the articles relative to each other when the container is transported.

A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.

A sheet cutting apparatus includes a cutting unit configured to cut a sheet, a blowing unit configured to send air toward the cutting unit, a container unit configured to contain scraps generated when the sheet is cut, a scrap path configured to allow the scraps travelling toward the container unit from the cutting unit to pass through, wherein the scrap path is formed of a member provided with openings for allowing the air sent by the blowing unit to pass through.

A cardboard box dividing device includes lower conveyors on which a plurality of connected cardboard box bodies are stacked and transported; a pressing device pressing, from above, the plurality of connected cardboard box bodies stacked on the lower conveyors; a cutting blade disposed along a width direction of the connected cardboard box body and dividing the plurality of connected cardboard box bodies stacked on the lower conveyors into a front part and a rear part; a lifting/lowering device relatively moving the plurality of connected cardboard box bodies on the lower conveyors and the cutting blade along an up-down direction; and a control device controlling the pressing device based on a lifting/lowering height of a loading upper conveyor at a time when a pressing reaction force at a time when the loading upper conveyor presses the plurality of stacked connected cardboard box bodies reaches a preset reference pressing reaction force.

A machine for folding, cutting, and stacking napkins is provided. The machine has a feeding station, at least one pair of folding rollers pivoting about horizontal rotational axes, a blade, and a pair of spacers having fingers configured to support the napkins stably downstream of the blade, with respect to a horizontal plane perpendicular to a direction of travel, the folding rollers being provided with circumferential slots for inserting the spacers.
