ABSTRACT:
The device for applying a coated plastics film to a substrate, consists of a housing (1) and an interchangeable cassette (4) which comprises a supply spool (5), an empty spool (8) which can be driven from this and an application tongue (7). The housing (1) has a through opening for the application tongue at its front end (1a) and a loading opening (3) for introducing and removing the cassette (4) at its opposite, rear end. The cassette (4) can be slid into the housing (1) from its loading opening (3) to the through opening in a straight line. A compression spring extending in the direction of movement of the cassette (4) is arranged in the housing (1), into contact with which comes a projection on the cassette (4), before the application tongue (7) has reached the through opening. A spring-loaded detent device (13, 15, 16a) with a press-button (14) is provided between the cassette (4) and the housing ( 1), by means of which the cassette (4) can be locked in its working position relative to the housing (1), and which can be released by actuation of the push-button (14), so that the cassette (4) is automatically pushed back into its position of non-use under the action of the compression spring, in which position the tip of the application tongue (7) lies within the housing (1).
