Abstract

The invention relates to a device for feeding a quasi-endless material web (4) to a manipulation device (19) receiving the material web (4), wherein a feed tension unit (8) is provided, through which the material web (4) is fed in an S-shape. The feed tension unit (8) comprises a pivotal feed dancer roller (12), the angle positions thereof being captured by a feed angle sensor (34) and fed to a control unit (36), by means of which the material web (4) is fed or retracted by a dispenser roller motor (3) in the direction of the manipulation device (19), depending on the deviation of the angle position from a reference angle position. Substantially uniform tension in the material web (4) is thereby ensured, even under extreme operating conditions.
