    摘要: A printer for printing endless paper webs on both sides has two printing stations with a web turnover station therebetween. The paper web is fed in parallel side-by-side to the two printing stations which are on the same rollers. The drive of the web through the printer is by a positive drive, using pins to engage holes in the paper web, for example, into the first printing station. The drive of the paper web thereafter is by friction drive to permit slippage in the drive to compensate for variations in paper length during heating, etc. The slippage is controlled by brakes or other drag inducing devices acting on one or both of the two portions of the paper web.

    摘要: A thermofixiug device for fixing toner images on a strip-shaped or sheet-like recording substrate (17) of an electrophotographic printing or copying machine contains a thermoprinting fixing station (11, 12) and a heated preheating saddle (15) located upstream of the thermoprinting fixing station in the recording substrate running direction. The preheating saddle (15) is designed as a low temperature saddle with the largest possible constructional length, so that the temperature difference between recording substrate (17) end saddle surface (24) is as small as possible. The preheating saddle has, in the recording substrate running direction, a plurality of heating zones (21, 23). A control device controls the heating zones (21, 23) in such a manner that, along the preheating saddle (15), an approximately constent thermal energy flow occurs on the saddle surface (24) to the recording substrate (17). For matching the preheating saddle (15) to various recording substrate widths, the preheating saddle is subdivided, transversely to the recording substrate heating direction, into individually drivable transverse heating zones (30/1 to 30/3).

    摘要: The device for transporting recording media (100), used especially in a fuser station of a printer or photocopier, comprises a counter-roll (201) and a feed roll (205), mounted movably relative to the counter-roll (201), between which rolls the recording medium (100) is transported by friction. Furthermore, a guide bar (214) is arranged in the manner of a balance beam with spacing parallel to the feed roll (205) and so as to be pivotable about an axis of rotation (216) relative to the feed roll (205). In order to press the feed roll (205) against the counter-roll in a force-compensating manner, as required, spring elements (218) are arranged on the guide bar (214) on both sides of the axis of rotation and are coupled to bearing elements (206) of the feed roll (205). The guide bar can be deflected via an adjusting motor (224) for controlling the position of the recording medium (100) between the rolls (201, 205).

    摘要: An electrographic printing or copying machine contains, by way of example, a preheating saddle (20,21) positioned upstream of a pair of fixing rollers in the recording substrate running direction and a braking element (10). The preheating saddle (20,21) and braking elements (10) form a gliding surface (23). Suction openings (18,19) in fluid communication with a vacuum-generating device ensure good contact between gliding surface (23) and recording substrate. With the aid of a valve (1), the vacuum can be matched to the operating parameters of the printing and copying machine, or to the parameters of the recording substrate.

    摘要: A printer for selectively printing on one or both sides of a web-shaped recording medium includes a paper turn-over apparatus in the paper conveying channel. The turn-over apparatus is a removable unit and can be changed from a turn-over operation for two sided printing to a parallel conveyance for one sided printing of two recording mediums. A conveyor that moves the recording medium through the printer has an adjustable width to adapt to different recording medium widths. The conveyor includes a return which returns the recording medium to the turn-over apparatus after being printed on one side. The return includes a traction roller pair and a lever to swivel one of the rollers in and out. A connecting channel leads from the traction rollers and includes guide baffles. Conveyor rollers are arranged along the connecting channel at less than the spacing of the folds in the folded recording medium. The guide surfaces for the recording medium have air openings to generate an air pillow between the recording medium and the guide surface.

    摘要: A printing or copying apparatus is provided having a thermofixing device for fixing a toner image to a sheet recording medium or substrate, such as paper. The apparatus has at least one cooling device operable to cool the substrate after it passes through the thermofixing device and before the substrate is stacked. The cooling performed by the cooling device prevents the toner image from undesirably sticking to an adjacently overlying substrate surface after stacking.

    摘要: An arrangement for the lateral positioning of a recording medium (100) in a printer or photocopier comprises a scanning arrangement (S) for establishing the ACTUAL position of the recording medium and a motor-drivable roll arrangement consisting of a counter-roll (201) and a pressure roll (205) which can be pivoted onto and away from the counter-roll (201), between which rolls the recording medium is guided. Furthermore, an apparatus (E) is provided for the controllable adjusting of the pressing force at the feed roll (205) on the counter-roll (201) along its roll length, and a control arrangement (P) which registers the ACTUAL position of the recording medium (100) via the scanning arrangement (S) and adjusts the pressing force of the feed roll (205) via the said apparatus (E) as a function of a predeterminable REFERENCE position. The arrangement is used preferably in the fuser station of an electro-photographic printer for the controllable lateral positioning of the recording medium (100).
