ABSTRACT:
BACKGROUND
The invention relates to an apparatus for transporting sheet-shaped print materials.
The majority of devices used in print processing and further processing require transporting paper or other sheet-shaped print materials through the device. In this process, the sheet-shaped print materials are aligned in different ways and manners, especially in the feeder area. Alignment of the sheet-shaped print materials is usually necessary in order to be able to carry out processing procedures in precise register, for instance, the printing of the sheet-shaped print materials with different colors, precisely-positioned folding or placement of holes in individual sheets.
For lateral alignment of the sheet-shaped print materials, stops are frequently used, against which the sheet-shaped print material is guided. So, for example in folding machines, transport elements like inclined transport rollers or a diagonally running belt are used to guide the sheet-shaped print materials against a stop during further transport. In order to improve or allow for contact between the sheet-shaped print materials and the transport elements, contact elements are frequently assigned to the transport rollers to produce adequate contact pressure between sheet-shaped print materials and transport elements. For this purpose, ball rails, among other things, are used. These ball rails have recesses in which balls that can turn freely are placed. Plastic or metal balls can be used for this. The balls are selected such that they, with respect to their surface finish and weight, are optimally matched to the characteristics of the sheet-shaped print materials, e.g., base weight, surface finish, etc.
In many applications, especially in copiers and/or digital printers, which typically have a number of different sheet formats in different supply bins, it is necessary to adapt the alignment of the sheet-shaped print materials to the format of the sheet-shaped print materials. Therefore, the stops are generally adjustable.
In further print processing applications, usually a high degree of flexibility is necessary so that a further processing device often consists of a plurality of individual processing devices that are arranged one after the other and connected to each other. Often the term used for this is an “inline” configuration of the individual processing devices. During inline further processing, not all of the individual processing devices are always active in further processing of the printed product. However, changing the existing configuration can usually only be carried out with great effort. Therefore, it is desirable and/or necessary that the individual processing devices that are not involved are switched off or operate in bypass mode. In this case, the sheet-shaped print materials must be transported from one individual processing device to the next without any changes, especially without changes to their alignment.
SUMMARY OF THE INVENTION
According to one aspect of the invention, an apparatus and process are provided for transporting sheet-shaped print material. A first transport element and a first contact element are actuated to transport a sheet-shaped print material with alignment against an alignment stop. A second transport element and a second contact element are actuated to transport sheet-shaped print material past the alignment stop without alignment against the alignment stop.
