A device for transferring a film from a tape carrier to a substrate. The device, otherwise known as a tape applicator, has a housing in which are arranged a supply wheel for the tape carrier coated with the film, and a take-up wheel (displaced radially with respect to the supply wheel) for receiving the tape carrier once the film has been separated therefrom. An application device, projects from the housing and presents the side of the tape carrier coated with film to the substrate. A drive connection together with a slip coupling is formed between the supply wheel and the take-up wheel by a friction drive, in which, when the supply wheel is driven by drawing off the tape carrier, the drive connection drives the take-up wheel at such a rotational speed that the tape carrier remains always tensioned. In order to improve the transfer of torque between the wheels, the wheels each have at least one disc-shaped wheel wall. The wheel wall of one wheel is formed with a slit and the wheel wall of the other wheel engages in the slit and is clamped therein. Rotational movement is thus transmitted from one wheel to the other. |
