An expanding machine includes a chassis, a feeding roller carrying a honeycomb paper, a guiding roller, and an expansion roller assembly including an upper expansion roller, a lower expansion roller, and a passage gap. The upper expansion roller includes upper projection assemblies that are staggered with respect to each other. Each of the projecting assemblies includes upper projecting portions and upper supporting portions that are alternate with respect to each other. The lower expansion roller includes projecting portions and supporting portions corresponding to the upper expansion roller. When the expansion roller assembly is put into rotation, the upper projecting portions correspond to the lower supporting portion, and the lower projecting portions correspond to the upper supporting portions, so that the projections that are separately arranged may pull and expand the honeycomb paper, making it not readily compress down the honeycomb paper or generating apparent compressing marking.

The invention relates to a carriage of a linear motion guide for arranging on a rail of the linear motion guide, said carriage having an at least substantially U-shaped cross-section and having at least one substantially U-shaped base body (15) which is supplemented with plastic components, wherein the carriage, in both legs of the U-shape, is in each case connected to at least one self-contained rolling body housing (7) which is kept open towards the rail in order to guide as precisely as possible on the rail and nevertheless being easy to assemble. According to the invention, at least parts of inner and outer boundary surfaces of a return channel (10) and both deflection channels (11) of one of the rolling body housings in the respective leg are formed by means of a one-piece plastic component in both legs of the carriage.

Disclosed herein is an apparatus for packing articles as well as a device for counteracting winding up of film or web material for an apparatus for packing articles, the packing being formed by at least one web material conveyed over at least one pulling roller, wherein the device for counteracting winding up is disposed in relation to the pulling roller and extending at least partially around the pulling roller, whereby is achieved an easy, secure and functional device that efficiently counteracts and obviates the possibility of web material being wound around a pulling roller.

Disclosed is a paper-sheet-feeding/conveying roller having a shaft, and a bi-layer roller material which is formed of an inner layer provided on the shaft and an outer layer. The inner layer provided on the shaft is a foamed elastic layer. The outer layer provided on the foamed elastic layer is a non-foamed elastic layer. The foamed elastic layer is formed of a foamed elastic body of silicone-modified EPDM.

A scanner includes a reading section configured to read a medium being transported, a discharge roller pair configured to nip the medium read in the reading section by a first roller and a second roller and discharge the medium, and a rib disposed in a position overlapping the discharge roller pair in a medium transport direction, the rib protruding from the first roller side toward the second roller side out of the first roller and the second roller, the rib including a first rib disposed on one side in a width direction intersecting the medium transport direction with respect to the discharge roller pair and a second rib disposed on the opposite side of the first rib in the width direction with respect to the discharge roller pair.

A sheet handling device includes a shaft, a roller, and a joint. The roller is detachably attached on an end portion of the shaft. The joint is mounted on the end of the shaft and has a claw at a tip of the joint. The claw of the joint is configured to position the roller in a thrust direction along the shaft while an inner circumferential surface of the roller is in contact with an outer circumferential surface of the shaft. The inner circumferential surface of the roller has a cylindrical shape.
