Abstract (en)
[origin: EP0388866A2] At a driving station, as is used in a device for threading in material webs, which has a driving wheel (12) driven by a motor (14) and a transport wheel (10) in engagement with the latter, it being possible for said transport wheel (10) to be brought into positive engagement with a threading element (1) which is movable in a guide (6), the drive wheel (12) and transport wheel (10) are so arranged that the pitch circle tangent (17a) at their common contact point (17) forms with the pitch circle tangent (18a) at the contact point (18) of transport wheel (10) and threading element (1) an angle ( beta ) whose angle bisector (19) is inclined at an acute angle ( beta /2) to the running direction of the threading element (1). Furthermore, the transport wheel (10) is mounted, so as to be movable against a force (F), at an acute angle ( alpha ) (likewise seen towards the running direction of the threading element (1)). The driving station according to the invention ensures a wear-free and jerk-free running-in, coupling and transporting of a threading element (1). <IMAGE>
