A device (1) for guiding a web (3) which consists of a rigid material and is curved in the transverse direction has a contact surface (20), against which at least one section of the web bears in such a manner that the web has there, with elastic cancellation of the transverse curvature, a longitudinal curvature which is curved around at least one transverse axis. In order to support the web on the device free of play and slip in such a manner that it can also be pressure-loaded in the longitudinal direction towards the device, two lateral support surfaces (14, 15) are provided, which lie opposite one another in the direction of the transverse axis (6), are inclined towards one another in such a manner that they converge away from the transverse axis, and which are arranged in such a manner that each web section which enters into the longitudinally curved region, as a result of the width enlargement which it undergoes in this connection, clamps itself immovably, in an elastically reversible manner, between the at least one contact surface and the two lateral support surfaces. …<IMAGE>… |
