ABSTRACT:
The apparatus comprises a support on which a rotatable wheel is mounted an area of the cylindrical surface whereof is in contact with a belt effective to press a yarn thereon which is led through an eye carried on an inlet arm and, respectively, through an eye carried on a yarn outlet arm, such arms being movable between a position whereat they hold the yarn in the nip between the belt and wheel, and a position whereat they hold the yarn out of contact with the belt. The inlet arm is positioned and dimensioned such that, in the condition whereby it holds the yarn inoperative, that is out of contact with the belt, the eye carried thereon is shifted to the opposite side of said belt relatively to a plane led through the longitudinal side edge of the belt lying closer to the eye; whereas, in the operative condition, the inlet arm eye is shifted to the same side of the belt relatively to said plane. Further, the inlet arm eye is located between the belt-to-wheel contact area and a fixed inlet eye which is in substantial alignment with the inlet arm eye, in the condition whereby it is at a position with the yarn inoperative, and the adjacent belt edge.
