For gentle premelting of running granulated hot melt adhesives on EVA or polyolefin base.
The extruder may be operated as a stand-alone or added onto regular commercial processing machines such as the core coating systems. A new geometry permits joint action with electronic temperature regulation for a gentle and use-appropriate melting with various adhesives. Particular care was taken with operating safety. For example, the system has a saftey start-up circuit that prevents the worm starting at too low a temperature. The intake area is cooled by means of cannules inserted into the funnel mouth so that the granules cannot block in this area. An adjustable post-run period allows for an idle run of the worm gears in the entry area during discontinuous operation.
