Abstract:
A device for transferring a film from a backing strip to a substrate, said device comprising:a housing; a first non-rotatable bearing component non-rotatably mounted on said housing; a first cylindrical bearing component rotatably mounted over said first non-rotatable bearing component for rotation about a first rotation axis; a second non-rotatable bearing component non-rotatably mounted on said housing; a second cylindrical bearing component rotatably mounted over said second non-rotatable bearing component for rotation about a second rotation axis; a supply reel on which a backing strip with film carried thereon is supplied; and a take-up reel for taking up the backing strip after the film is transferred therefrom to a substrate; wherein: said first non-rotatable bearing component and said first cylindrical bearing component form a pivot bearing for said supply reel; said second non-rotatable bearing component and said second cylindrical bearing component form a pivot bearing for said take-up reel; a dividing joint is defined between said bearing components of said at least one of said pivot bearings; a return stop is provided on at least one of said pivot bearings for said supply reel and said pivot bearing for said take-up reel; said return stop comprises a locking pawl meshing with a gear ring; said locking pawl is arranged on one of said bearing components of said at least one of said pivot bearings against a spring force so that said locking pawl yields elastically; said locking pawl projects beyond said dividing joint; said gear ring is arranged countersunk in an annular groove on the other bearing component of said at least one of said pivot bearings; said gear ring is co-axially arranged with respect to a cylindrical bearing surface of said one of said bearing components; and said locking pawl is co-axially arranged with respect to a cylindrical bearing surface of said other bearing component.
