Title:
MELTER WITH SELF-CLEANING FILTER
Document Type and Number:
WIPO Patent Application WO/2021/055570
Kind Code:
A3
Abstract:
In one example, a melter (110) has a housing (114), a heater (208), a vent (164), and a filter medium (174). The housing defines a receiving space (118) that supports adhesive therein. The heater heats the receiving space of the housing to melt the adhesive. The melter defines an adhesive inlet therein that receives adhesive carried by a transport supply gas into the receiving space. The vent extends through a wall of the melter and permits the transport supply gas to escape from the melter. The filter medium is supported in the vent to capture particulates from the transport supply gas escaping the receiving space, and is positioned relative to the receiving space such that heat from the receiving space causes the particulates captured by the filter medium to melt and fall into the receiving space.
