Abstract
A web layer (2) is deflected on conical deflectors (31, 34) in laterally opposite directions, thereby permitting lateral but parallel displacement of the downstream web section (10) with respect ot the upstream web section (6) at low hight extension of the device (1) and at small deflector angles. The deflectors (31, 34) can be separately positionally adjusted in a tumbling motion and are fixed to a support (14) with cardan joint (54).
