<p>A system for applying pasty two-component masses stored in tubular bags, consists of a base unit (1), equipped with a hollow cylindrical chamber. At the front of the system an extrusion arrangement (2) is installed, equipped with means to activate the two-component mass. A press-out piston to empty the tubular bags, which can be displaced electromechanically, is located inside the base unit (1). The piston has a recess to receive the emptied tubular bag. To facilitate the removal of the folded tubular bag, a ring is provided that can be pushed onto the piston, and which prevents the tubular bag wrap from adhering smoothly to the piston's recess. In this manner, the tubular bag - together with the ring - can be pulled off the piston without great exertion.</p> |
