Porous warp sizing apparatus

摘要: An apparatus and method for sizing warp yarn utilized in preparing a loom beam weaving are disclosed. A porous application roll (A) is applying material onto sheet of yarns (12) passing between pressure (30) the roll. The includes continuous cylindrical surface (B) formed around entire periphery having an extent at least as great width. intermediate distribution layer (C) provided next to disbursing surface. flow control membrane (D) pore size less than that occupies boundary region metering material. When passage discontinued, moved idle position by actuator (38). In position, liquid (72) made contact maintain it moist condition. wiper blade (80) remove excess liquid. removed before again used apply material, so not diluted.
