ABSTRACT:
A loom left yarn store receives yarn being supplied from a weft package (5) and makes the stored yarn supply available to be drawn off from the store intermittently for picking into the shed of a loom. The store includes a stationary drum (11) which is supported by way of its outer periphery and which is adapted to receive a yarn supply (51) to be stored. A winding element (14) rotates around the drum periphery (111) and has an element (142) for entraining the weft yarn (52). One or more yarn entraining elements (142) can be brought into and out of operation in accordance with a program and when in operation can wind yarn on the drum periphery (111). The drum (11) is supported by way of its outer periphery horizontally by magnets or vertically by means of brushes. The winding element (14) is a ring which rotates continuously around the drum periphery and from which at least one pin (142) engages periodically in a recess (111) in the drum. The store contains few mechanical means and the retaining or securing elements (142, 152) requiring intermittent actuation are of reduced mass.
