Abstract

Abstract A combination tension control and slub catching device wherein there are confronting fixed and movable members provided with confronting surfaces between which the yarn moves. The movable member is yieldably held engaged with the fixed member and there is an array of parallel bars mounted on the fixed member edge to edge transverse of the direction of movement of the yarn with the surfaces thereof at one side engaged with the surface of the movable member. An adjustable support on the fixed member arranged in engagement with the ends of the bars at the opposite sides limits displacement of the bars relative to the surface of the movable member, and a spring-pressed plunger supported on the fixed member in engagement with a pressure plate applies pressure to the bars in a direction to press them against the surface of the movable member.
