APPARATUS FOR APPLYING FOAMED COATING MATERIAL TO TRAVELING TEXTILE SUBSTRATE

摘要

PURPOSE: An apparatus for applying a foamed coating material to a traveling textile substrate and its method are provided, which apparatus is a coater for applying foamed coating material to a traveling textile substrate. CONSTITUTION: The coater(10) comprises a frame(11); a flush pan(12); an applicator(13) having an open slot; a pivot shaft(24) journaled in a pair of support arms that are pivotally mounted to the frame; a piston-cylinder which allow the applicator to move between an operating position wherein the open slot is adjacent the traveling substrate and a flush position wherein the open slot is adjacent the flush pan by pivoting the supporting arms and rotating the pivot shaft; and optionally a foam generator. The method comprises the steps of supporting the traveling substrate between the two supporting arms; contacting the traveling substrate with a foam applicator(13); and forcing a metered amount of foamed material at least partially into the interstices of the textile substrate before the foamed coating material collapses.
