Abstract
A textile yarn slashing system having a foam applicator disposed therein for pre-wetting the sheet of yarns prior to passing through the size box. The foam is delivered under pressure and a resilient hold down member opposes the slot to create a space for foam on the opposite side of the yarn sheet from the slot for application of foam to both sides of the yarn sheet. A flexible cover sheet covers the surface of the hold down member and is shifted to replace a worn portion with an unworn portion opposite the slot. A valve assembly is incorporated in the applicator to close off the passage to the slot and permit bypass flow of the foam. End seal blocks have rigid metallic outer chamber engaging surfaces and resilient material interior of the surfaces to press the surfaces against the sides of the chamber adjacent the slot. A plurality of horizontal tubes may be used as an alternate to the slot with one or more yarns traveling through each tube.
