Abstract
The invention relates to a device for feeding a quasi-endless material web () to a manipulation device () receiving the material web (), wherein a feed tension unit () is provided, through which the material web () is fed in an S-shape. The feed tension unit () comprises a pivotal feed dancer roller (), the angle positions thereof being captured by a feed angle sensor () and fed to a control unit (), by means of which the material web () is fed or retracted by a dispenser roller motor () in the direction of the manipulation device (), depending on the deviation of the angle position from a reference angle position. Substantially uniform tension in the material web () is thereby ensured, even under extreme operating conditions.
