Apparatus for applying foamed coating material to a traveling textile substrate

A coater for applying foamed coating material to a traveling textile substrate including a frame, a flush pan, an applicator having an open slot, a pivot shaft journaled in a pair of support arms that are pivotally mounted to the frame and piston-cylinder mechanisms to move the applicator 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 support arms and rotating the pivot shaft. Foamed coating material is applied by supporting the traveling substrate between two spaced support elements, contacting the traveling substrate with a foam applicator, and forcing a metered amount of foamed material at least partially into the interstices of the textile substrate before the foamed coating material collapses. A metered amount of foamed coating material is applied onto or into a textile substrate regardless of textile substrate structure and regardless of the viscosity of the coating material. The foamed coating material may be flushed from the coater by stopping flow of foamed material through the applicator, moving the applicator to the flush position, and commencing flow of a flushing fluid through the applicator and into the flush pan. Foamed coating material may also be flushed from the applicator by stopping flow of foamed material through the applicator, commencing flow of a flushing foam through the applicator, stopping flow of flushing foam through the applicator, and commencing flow of a flushing fluid through the applicator.
