Mechanism for feeding yarn positively machine ge-neros point.

摘要

Mechanism to positively feed yarn to machines mere point, essentially characterized in that it consists of a support on which is mounted freely rotating a bearing by which axial hole passes the yarn from the reel and stretched by the machine, which hole is coax the spool shaft, being secured with bearing a radial arm at the upper end is topped by a thread guide, all so that the adción draw the thread through the machine bearing on the arm, impressing rotation about the spool and so that, when the wire is consumed by the machine in larger amount than the yarn is wound in a predetermined number of turns on the reel, the large arm in a direction tending to decrease the number of turns of existing thread on the spool , whereas when the machine consumes less thread which is wound on the reel, the arm rotates in a direction that tends to accumulate more turns of wire in the reel, must be constant the number of turns of wire on the reel so that the power is positive, which is achieved by printing at higher or lower speed spool and then locking the arm.
