Mechanism for the supply and takeup of a transfer tape in an applicator

摘要

A mechanism for the supply and takeup of a transfer tape for an adhesive or correction coating in an applicator comprises a supply reel collar (12) from which the transfer tape can be unwound. The supply reel collar is fitted on a supply gear (7) about its hollow cylindrical shaft portion (9) having an upwardly facing shoulder on its outer surface and a downwardly facing shoulder on its inner surface. A retainer (16) has an upper portion engaging the collar and a lower portion engaging the downwardly facing shoulder. A coiled spring (14) is held in a compressed shape between the upwardly facing shoulder and the upper portion of the retainer to ensure tight engagement between the shaft portion and the retainer and thereby the supply gear and the collar.
