Abstract: A color printing unit includes one printing station for each color along with one anode roller. A continuous transfer belt is guided over a deflection roller and a control roller. One or more sensors measure a property of reference markings printed on the transfer belt. A control device for controlling and adjusting the transfer belt acts on the control roller through an actuating motor as a function of the detected properties of the reference markings. The one or more sensors are arranged in the area of the control roller for the transfer belt, by which an additional tension roller saves costs and space. During the measurement, at least for the period in which the printed reference markings pass under the one or more sensors, relative movements between the one or more sensors and the control roller are ruled out.

Abstract: A sheet-folding machine has a housing having an off-line intake slot and, offset therefrom, an on-line intake slot, a manual sheet-input table on the housing juxtaposed with the off-line intake slot for feeding of a sheet manually into the off-line intake slot, and an automatic sheet feeder juxtaposed with the on-line intake slot and capable of cooperating with a sheet-processing device to receive a sheet therefrom and feed it into the on-line intake slot. Respective off-line and on-line guide chutes in the housing each have an upstream end at the respective slot and a downstream end. The downstream ends meet at an intersection. A roller-type folding unit in the housing receives a sheet to be folded at the intersection and folds it.

Abstract: A large-format scanner having an imaging element and connected to a PC by a standard interface of predetermined maximum bandwidth is provided with a variable-speed document feeder and with a device upstream of the imaging element for detecting the width transverse to the feed direction of a document being moved through the apparatus by the feeder. As soon as the document width is detected and before the document reaches the imaging element, any sensors of the imaging element that will not confront the document are turned off and the document speed is adjusted so that the sensors left on produce a data output of a bandwidth close to but below the maximum bandwidth of the interface, with wide documents being fed faster than narrow documents.

Abstract: A method for scanning large-format documents by way of a large-format scanner, which is connected to a PC (11) via a standard interface (10), is to be further developed, so as to omit prescans, to optimize the scanning rate, to significantly increase productivity between the application of the document and the storage of the data on the PC, and to obtain cost-efficient scans.

Abstract: Hydraulically damping rubber bearing consisting of an inner part, an outer part a certain distance concentrically or eccentrically outside the inner part, and a rubber part between the inner part and the outer part, in which rubber part at least one damping medium-filled chamber is provided. A certain distance concentrically inside the inner part, another tubular part is provided, part of the outside surface of this tubular part and part of the inside surface of the inner part being at least partially spherical, an elastic element being provided between these two spherical areas.
