Patent ID: 7422207

Claim:
An apparatus for transporting sheets from paper or other material that is form-retaining in its plane, comprising: a transport track with a first track portion extending in a first direction and a second track portion downstream of the first track portion, extending in a second direction other than the first direction; at least one transport roller with a circumference, of which a circumferential section extending through an angular range of the circumference forms a bend from the first track portion to the second track portion; and at least one sheet guide with a sheet guiding surface facing the circumferential section, which sheet guiding surface extends coaxially with at least a portion of the circumferential section, the sheet guide being tensioned between an upstream point of engagement and a downstream point of engagement, where the sheet guide is mounted to the downstream point of engagement such that, in operation, at the downstream point of engagement, the sheet guide is stationary in the direction of the at least one sheet guide; wherein at least the sheet guiding surface or the circumferential section is yieldably supported for yieldably urging towards each other the sheet guiding surface and the circumferential section for exerting normal force on sheet material between the sheet guiding surface and the circumferential section; and wherein the circumferential section is supported such that in reaction to a friction force directed upstream in the circumferential sense of the circumferential section, exerted on the circumferential section, normal force exerted by the circumferential section, directed to the sheet guiding surface, is reduced.
