Abstract
An embodiment of the invention relates to a frictional clutch for a hand-held device for transferring a film from a backing tape onto a substrate. The frictional clutch in this embodiment includes a supply reel and a take-up reel rotatably mounted coaxially to each other, one of the reels including a free space bordered by a circular ring surface of the other reel, a spring element being disposed in the free space, with the spring element pressing elastically against the circular ring surface. In one embodiment of the frictional clutch, the free space is located radially outside the convex circular ring surface and the spring element is biased radially towards inside against the circular ring surface.
