A sheet transfer guide, which is disposed along a sheet conveyance passage through which a sheet passes, provided to guide the sheet, and is included in an image forming apparatus and an image reading device, includes a base material, a coat layer formed on the base material and having a surface roughness smaller than a surface roughness of the base material, and a guide face to which the sheet contacts. The coat layer is formed on the guide face.

A method and a device for printing and drying a plastic film web, especially a polypropylene (PP), polystyrene (PS), or polyethylene (PE) film web, employ several offset printing mechanisms for printing the film web with different ink applications and at least one flame drying station. The device also includes a drawing roller, which is arranged between a last printing mechanism and the at least one flame drying station, contacts the unprinted surface of the film web, and applies tension to the film web.

The device can include several offset printing mechanisms for printing the film web with different ink applications and at least one flame drying station, characterized by a drawing roller, which is arranged between a last printing mechanism and the at least one flame drying station, and which can contact the unprinted surface of the film web, and apply tension to the film web.

A lamination tape feeding system for an electrode plate substrate is provided. The lamination tape feeding system includes an input roll for inputting a lamination tape to be attached to an uncoated region of the electrode plate substrate to which an active material is applied, a plurality of guide rolls for guiding the supply of the lamination tape input, a discharge roll for discharging the guided lamination tape. The system also includes at least one crown roll that is disposed in a path of the lamination tape between the input roll and the discharge roll, disposed in the path between the guide rolls, and has a maximum height at the center of a width direction that intersects the moving direction of the lamination tape, with the height decreasing toward ends the at least one crown roll.
