Abstract
The present disclosure provides apparatuses for filtering hot adhesives. In certain embodiments, the present disclosure provides a filter plate that is used in conjunction with a heater and a valve assembly. In other embodiments, the present disclosure provides a filter screen that is located in a recess of the valve assembly housing, in addition to or in lieu of the use of a separate filter plate. Both embodiments utilize one or more ribs, which aid the flow of adhesive, facilitate the transfer of heat from the heater to the valve assembly, and optionally, physically support the filter screen.
