A digital printer or copier machine () is proposed for the single-sided or double-sided printing of a substrate (), with at least one fixing device () for fixing toner onto the substrate (), whereby the fixing device () has at least one heating device for fusing the toner. The machine has, in addition, at least one transport device (), in order to supply the substrate () to the heating device, to guide it past the heating device and/or to further transport it from the heating device, whereby the transport device () has at least one suction belt () that is provided with a number of through-passage openings () and can be impinged with a vacuum. The machine () is characterized in that the suction belt () is constructed as a mesh.

A piston rod-less linear drive has an elongated housing containing a guide slide moving in the longitudinal direction. The connection between the entraining member and the guide slide is with the interposition of an abutment unit attached to the guide slide, such abutment unit furthermore serving to limit the path of movement of the guide slide.

The invention relates to a device for manual replacement of a roller ( ) of a copying machine, the roller being equipped with carrying means, in which it can turn freely around its center axis (X ), and the machine (F) on the one hand having rollers ( ) in a roller pair arrangement for routing through and delivering a recording medium (S) in the form of a sheet or strip, which rollers can be operated in rotation in an adjoining, axially parallel arrangement in the bearing points (L ; L ; L ; L ) of the machine, and are supported by their axial ends, and on the other hand there being manually activated means for releasing/fixing the rollers in their bearing points and for separating/compressing ( ) the rollers in the radial direction for purposes of removing them from and inserting them into their bearing points. To arrive at a device which makes it safer and easier to carry out customer service of the machine, especially replacement and deposition of heavy and large rollers, and which moreover has a simple, compact, economical structure, the roller ( ) has on its two axial ends one carrying handle (T ; T ) each as the carrying means which is located eccentrically to the center axis (X ) of the roller such that the roller hangs down vertically underneath the carrying handles due to its weight in the manual removal from and insertion into the input/output openings of the bearing points (L ; L ) of the machine, which openings run vertically and radially.

Device for manual replacement of the roller of a copying machine

A device for manual replacement and transport of a roller ( ) of a copying machine, for example, which makes it easier and safer for service, replacement and transport of hot, heavy and large rollers. There is provided a protective container ( ) which can be slipped over a roller ( ), which has been released in the machine, and its carrying apparatus. The roller ( ) can be removed from the bearing points (L , L ) of the machine with the protective container ( ) using its carrying apparatus which project out of the protective container, and can be inserted into the bearing points. Carrying handles for the carrying apparatus, enable the roller to be guided into slotted openings and, can be radially inserted into bearing points, and can be removed from them. A transport container ( ) into which the protective container ( ) provided with the roller ( ) can be manually inserted and removed.

At the free end of a pivotable arm (1) of an aligning device, two wheels (4, 6) of identical diameters are mounted for independent rotary movement, such wheels being driven by a shaft (2). The wheels (4, 6) are each eccentrically offset from the axis of rotation (2a) of shaft (2) by the same amount (26, 27)and are uniformly spaced about said axis. With respect to a plane running perpendicularly to the axis of rotation (2a) of shaft (2), each wheel (4, 6) is mounted at an acute angle (.alpha.) such that adjacent wheels (4, 6) are arranged in a V-shaped configuration. The eccentrically (26, 27) and the angular position (.alpha.) of the wheels (4, 6) are related such that the contact surface (4b and 6b) of each wheel (4 and 6, respectively) resting on the sheet to be aligned carries out a movement transversely to the sheet-entrance direction (A) and towards the lateral limiting wall (18).

Device for stacking and aligning individually supplied sheets

A device for aligning supplied sheets into a stack in a collecting tray includes a pivotable arm that has a free end. First and second drivable wheels are mounted at the free end of the pivotable arm for contacting each supplied sheet to be aligned. A lifting device including an electromagnet is connected to the pivotable arm for lifting the pivotable arm, and a control device is connected to the electromagnet for selectively controlling lifting and lowering of the pivotable arm and first and second drivable wheels.
