Abstract (en)
[origin: WO2009068310A1] The invention relates to a device for successively melting a solid working material, such as a hot melt adhesive (16), packed in a packaging bag (18), and for pressing the molten working material out of the packaging bag, comprising a cylindrical receiving chamber (12) provided with at least one outlet opening (14A) at the end for receiving the packaging bag (18) filled with the working material and having a front end (18b) and a back end (18A). The invention further comprises at least one heating element (30) in the region of the at least one outlet opening (14A) for melting the working material at the front-end of the packaging bag (18) having a discharge opening (18C) for the molten working material, and further comprises a pressing device (20) with a pressing plunger (22) that can be displaced within the receiving chamber (12) and acts on the back end (18A) of the packaging bag (18). The device is protected from contaminations by molten working material when used with undersized packaging bags that are extremely filled in that the receiving chamber (12) at the outlet end (12D) thereof facing the at least one outlet opening (14A) comprises a ring-like constriction (40) with a peripherally sealing contact surface (40A) for the packaging bag (18) at least at the edge zone (18D) thereof surrounding the discharge opening (18C).
