Abstract: An apparatus for steering a belt includes a steering roller supporting the belt, a rotatable element and a transmission. The steering roller is rotatable about a first axis and pivotable about a second axis, the second axis being substantial perpendicular to the first axis. The rotatable element is rotatable about a third axis, the third axis being parallel to the first axis. The transmission is arranged for converting a rotational motion of the rotatable element about the third axis into a pivoting motion of the steering roller about the second axis. The rotatable element is rotatable by a frictional force between a side portion of the belt and the rotatable element. A method for steering a belt in a steering mechanism includes such an apparatus.

Abstract: A method and means for transferring two images substantially simultaneously and directly to different sides of a receiving sheet, wherein the images are formed one behind the other on an endless belt trained about support rollers. An image transfer zone in the form of a loop between the transport rollers is formed in the belt via a guide roller, thereby bringing the two image towards one another. During transfer of the images to the receiving sheet, the direction of rotation of one of the transport rollers is reversed.

Abstract: A fixing device for fixing a powder image on a receiving sheet in a fixing nip formed by a fixing roller and a pressure roller which has a lower flexural stiffness than the fixing roller. These rollers are pressed against one another by a stationary cushion filled with compressed air and pressing against the pressure roller in a pressure zone situated opposite the fixing nip.When the pressure roller and the fixing roller are driven, tangentially directed frictional forces are exerted on the pressure roller that causes the pressure roller to deflect against a curved support surface which limits the deflection. The pressure roller deflected in the operative position causes a receiving sheet fed through the fixing nip to be stretched in a direction transversely of the direction of conveyance to eliminate any bubbles or corrugations in the receiving sheet.

Abstract: Apparatus for transporting sheetlike originals past an exposure plate (10) of a copying apparatus, of the kind in which a flight of at least one endless belt (25) is driven over the exposure plate, is provided with a device (80) for applying a solid abherent material (85) to that surface of the belt (25) which comes into contact with the exposure plate (10).
