Abstract

The invention relates to a manual device for transferring a film consisting for example of adhesive, covering or coloured material from a backing strip to a substrate, with a housing in which a supply reel and a take-up reel for the backing strip are mounted so that they can rotate via a pivot bearing, which is formed by two coaxially arranged bearing components, engaging in each other like sleeves in the region of an annular or hollow cylindrical bearing joint, of which one bearing component is held on the housing so that it cannot rotate and the other bearing component is a part of the relevant reel support and in the course of which a return stop is provided for both reels with a locking pawl which meshes with a gear ring. To guarantee a compact design and economical fabrication, the locking pawl is arranged on the one bearing component against a spring force so that it yields elastically and the gear ring is arranged on the other bearing component.

Dependent claims

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.
