Abstract (en)
[origin: EP0310731A1] In such a device for the transport of record carriers (20, 29) in printers and, in particular, in matrix printers, individual sheets (21) or, alternatively, continuous webs (20) are processed both with and without edge perforations. In this arrangement, a tractor pair (11) for continuous webs (20) and driven and undriven pressure rollers (12, 17) or pressure roller pairs are associated with a platen roller (5). <??>To reduce the manufacturing and assembly costs for alternative processing of edge-perforated continuous webs, unperforated continuous webs, single sheets, self-copy sets and form sets, it is proposed that one or more groups (24, 25) of pressure rollers consisting in each case of a plurality of pairs (26) of rollers are provided, that each group (24, 25) of pressure rollers is arranged on its own bearing frame (27) and that the bearing frames (27) are adjustable parallel to the platen (6) from a resting position to an operating position or vice versa by means of a common adjustment device (28). <IMAGE>
