ABSTRACT:
An applicator for a film carried on a tape has a housing having a main part and a cover part that normally fit complementarily together. A supply spool on which the tape carrying the film is wound is rotatable in the main housing part. A takeup spool onto which the tape is wound is rotatable in the main housing part adjacent the supply spool. A slide is displaceable longitudinally in the housing between a retracted inner end position relatively close to the spools and an extended outer end position relatively far from the spools and projecting from the housing. The tape is spanned over an applicator foot fixed on and displaceable with the slide. Structure on the housing releasably retains the foot and slide in the front extended position. The spools can be replaced by removing the housing cover part and then pushing the foot back into the inner end position, thereby taking all tension off the tape. The two spools are then removed and a new set of spools joined by a new tape are set in place. The new tape is hooked over the retracted foot and same is pushed into the outer end position, thereby tensioning the tape. The cover part is reinstalled and the reloading is complete.
