Abstract:
1. A device for successively melting a solid working material, and for pressing the molten working material out of a packaging bag, comprising a cylindrical receiving chamber provided with at least one outlet opening at the end for receiving an associated packaging bag filled with an associated working material, and the associated packaging bag having an associated front end and an associated back end, at least one heating element in the region of the at least one outlet opening for melting the associated working material at the associated front end of the associated packaging bag having an associated discharge opening for the associated molten working material, and a pressing device with an ejection piston that can be moved within the receiving chamber and acts on the associated back end of the associated packaging bag, wherein the ejection piston is provided with a head plate that has a cross-sectional configuration that is smaller than a cross-sectional configuration of the cylindrical receiving space and smaller than a cross-sectional configuration of a stripper plate of the ejection piston, and moves axially relative to the ejection piston and its stripper plate toward the at least one outlet opening wherein a spring arrangement biases the head plate toward the at least one outlet opening.
