A film winding system is disclosed having a first winding station which is configured in a winding position to wind the film web into a film bale. A contact roller and a compensating roller are provided, wherein the contact roller is arranged adjacent to the first winding station in the winding position and is configured to guide the film web to the first winding station. The compensating roller is located before the contact roller in the direction of travel of the film web and is configured to guide the film web to the contact roller and to set a film tension. A first adjustment device is provided and configured to move the contact roller towards the winding station or away from the winding station, thereby enabling the setting of a specific contact pressure between the contact roller and the film bale. The first adjustment device comprises a slide system or an adjusting spindle.

A media transport includes a feed roller to be rotated in a first direction, and an input/output roller to be rotated in the first direction to direct media into a media path with rotation of the feed roller in the first direction, where the feed roller is to be rotated in a second direction opposite the first direction to advance the media within the media path and, with the rotation of the feed roller in the second direction, the input/output roller is to be temporarily decoupled from rotation with the feed roller.

A paper separating roller, including a shaft body, a first friction member and a second friction member is provided. The first friction member covers a first surface of an outer periphery of the shaft body. The second friction member covers a second surface of the outer periphery of the shaft body, wherein the first friction member and the second friction member are formed of two different materials. With the design of the friction members being formed of composite materials, the paper separating roller has the advantages of two different material features at the same time, such that a wider range of performance capabilities can be achieved.

A rubber composition capable of manufacturing a sheet transport roller having an excellent friction coefficient and wear resistance. A sheet transport roller rubber composition contains an ethylene-α-olefin-diene copolymer as a base rubber, a sulfur-based crosslinking agent, and a coumarone-indene resin. It is preferable that the sheet transport roller rubber composition be obtained by mixing the base rubber and the coumarone-indene resin at a temperature equal to or higher than a softening point of the coumarone-indene resin to prepare a mixture, and then mixing this mixture with a sulfur-based crosslinking agent.

A paper feed roller 1 is used in a paper feeding unit in an electrophotographic image forming device. The paper feed roller 1 includes a non-foamed elastic body 2 having an embossed surface 21 including crest-like parts 211 and valley-like parts 212. The embossed surface 21 has many dimple parts 213 recessed inward on bottom surfaces of the valley-like parts 212 or on the bottom surfaces and lateral surfaces of the valley-like parts 212, and does not have the many dimple parts 213 on top parts of the crest-like parts 211. A diameter of the dimple parts 213 can be set to be 1 to 100 μm and an arithmetic average height Ra of the embossed surface 21to be 3 to 50 μm.

A tape dispenser comprises a main body, a blade, and an adhesive portion provided with a pressure-sensitive adhesive on a surface thereof. The adhesive portion is mounted below the blade and protruded from the main body. After a tape is cut by the blade, the adhesive portion contacts and adheres to the back of the tape's end so as to prevent the tape's end from flapping freely or unintentionally sticking back to the original location. At the next use, the adhesive portion can press the tape's end onto an object that needs to be taped.

An image forming apparatus includes a feeding unit, a detection unit provided downstream of the feeding unit, a measurement unit that measures a measured time from the start of conveyance of a recording material to the detection of the recording material, and a determination unit that performs renewal determination for determining whether the feeding unit has been replaced with a new feeding unit. Thus, replacement of the feeding unit with a new feeding unit can automatically be detected.

A laminated film, including an adhesive layer peelably laminated on a base film, and a carrier film overlapping each other are passed between a bladed roller including a plurality of disk-shaped slitting blades arranged at a pitch of 0.5 mm or less and an anvil roller with the laminated film on the bladed roller side to slit the laminated film by score cutting. The slitting blades have a blade angle of 30° or less. By doing so, the laminated film including the adhesive layer peelably laminated on the base film is silt to have a tape width of 0.5 mm or less in such a way that the base film and the adhesive layer do not peel apart and the protrusion of the adhesive layer is suppressed.

The roller comprises a covering layer made of a fibre composite material and a cylindrical roller main body having an outer first lateral surface, a first end section and a second end section. The covering layer completely surrounds the first lateral surface in the circumferential direction. A first edge region of the covering layer extends beyond the first end section, is folded over inwards and is fixed in relation to the roller main body. In a crosslapper, the roller can be provided as a deflection roller of a conveyor belt. In a carding machine, the roller can be provided as an engagement roller for engagement with fibre material.

For the defects that manual adhesive tape pasting is low in efficiency and high in cost, and it is difficult to automatically paste adhesive tapes at specified positions of inner and outer surfaces of an item according to a certain length through a handheld box sealer and an adhesive tape seal pasting mechanism, a cantilever type plane automatic adhesive tape pasting device is invented. A liftable two-stage telescopic cantilever adhesive tape pasting head structure, a roller type automatic adhesive tape feeding structure, an adjustable fixed-length cutting structure and a roller type pasting structure are adopted for the device to achieve the automatic adhesive tape pasting on inner and outer side planes of an item. After the item needing adhesive tape pasting is positioned, the pasting process is completely automatically conducted without manual participation, the labor intensity is reduced, the labor efficiency is improved.
