ABSTRACT:
The present invention relates to methods of and apparatus for supplying weft thread carriers. In this method a thread is wound in the form of coils onto a spool of a carrier whereupon the carriers along with the thread are admitted into a weaving zone whereby an elongated section of the thread is formed to be sequentially separated from the coils, with the elongated section being thereafter pulled in a direction opposite to that of feed and, while being pulled the elongated section is arranged on a straight line connecting a thread guide and a braking point which, to compensate for the length of the pulled portion of the straight section, is moved away from the thread guide by a distance equal to this length.
In an apparatus for practicing this method a device for compensating for the portion of the elongated section comprises a bell crank installed on a disk on one arm of which bell crank there are located braking means and a stationary profiled cam cooperating with a free arm of this bell crank for the braking means to be moved away from the thread guide.
