A core prevents a battery separator wound there a round from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.

Cutting systems and methods capable of performing a variable cutting operation on a continuous web. The system includes a first cutting apparatus configured to receive the web and perform a cutting operation thereon to produce unfinished documents, and a second cutting apparatus configured to subsequently perform a trim cutting operation thereon to produce finished documents of selectively defined finished lengths, wherein the second cutting apparatus has a feed direction that is perpendicular to a feed direction of the first cutting apparatus. The system includes a conveyor system configured to receive the unfinished documents from the first cutting apparatus, arrange the unfinished documents into a stream of shingled documents traveling in the feed direction of the first cutting apparatus, and turn the unfinished documents at a right angle to travel in the feed direction of the second cutting apparatus without changing their orientation.

A web tensioner, a web slitter, a method of tensioning a web, and a method of slitting a web are provided. A corrugated edge nip is used in the tensioner, the slitter, and the methods of tensioning and slitting. The corrugated edge nip can provide a crossweb tension to a suspended web or film in a web line. The corrugated edge nip can be used in conjunction with, for example, a rotary shear slitter to improve slit edge quality.

The present invention comprises: a support roller part rotating while supporting the lower side of a transferred sticker sheet; a half-cutting roller part provided at the top of the support roller part so as to rotate by engaging with the support roller part, and having a half cutter for cutting a printed part of the sticker sheet passing the support roller part; and an anti-adhesion fluid supplying unit for applying an anti-adhesion fluid on the surface of the half cutter coming into contact with the printed part of the sticker sheet.

The apparatus for processing flat objects includes a transport system with several rotatably mounted conveyor rollers, the flat objects transportable in the direction of transport, and at least one releasably mounted tool module releasably coupled to only one drive shaft or to a lower and an upper rotatably mounted drive shaft; is supported displaceable along the only one drive shaft or the lower and the upper drive shaft; and is equipped with tool parts for processing the flat objects, of which at least one is drivable by the lower or the upper drive shaft. The tool module is supported by a tool carrier which is displaceable by means of a rotatably mounted setting shaft in parallel to the only one drive shaft and to the lower and the upper drive shafts, and which tool carrier has at least one holding element which serves for releasably holding the tool module.

A printed unit block aligning device includes a supporting element and an alignment transfer rail. The supporting element is opened and closed between a supporting position and a releasing position. The alignment transfer rail receives the group of the printed unit blocks dropped in response to move of the supporting element to the releasing position, aligns the printed unit blocks in each line unit block in a vertical direction, and feeds the printed unit blocks vertically at a constant speed using alignment transferring element. An electrical controlling element is provided that electrically controls timing of dropping the printed unit blocks from the supporting element onto the alignment transfer rail. While a speed of transfer of the horizontal feeding and transferring element are uniform for any imposition structure, the electrical controlling element controls timing of dropping the printed unit blocks in a manner that depends on the numbers of layers in each vertical line in different imposition structures.
