Abstract

In a device for the paper transport of single sheets and/or continuous paper in office machines, in particular in matrix printers, there are provided in pairs and at least separately driven friction rolls (1, 2) which are disposed rotatably in side plates; the friction rolls exhibit a length to diameter ratio of from 30:1 to 50:1 and are therefore very long and very thin. In order to provide the friction force in a uniform manner over the entire length of the very long and thin friction rolls, it is disclosed that the positive running bending line (16) of a first feed roll (1) based on its support forces (14a, 14b) in the printer frame (15) and the negative running bending line (17) of a second friction feed roll (2) based on its support forces (14a, 14b) in the printer frame (15) are tuned to each other such that the two bending lines (16, 22) run approximately parallel.
