Abstract
A weft yarn store for a loom includes a stationary drum (24), a winding arm (3) for winding weft yarn (20) on to the periphery of the drum, and a separating device (11) which separates groups of yarn turns (21, 22) from one another. A clamping facility at the weft yarn departure end of the drum (24) determines the release of a length of yarn for picking into the loom. The clamping action is accomplished by such a lever (14) mounted within the drum and working against an element (15a) mounted outside the drum (24). The outer clamping element is resiliently mounted in a retaining element (16) which secures the drum (24) against rotation. The clamping facility (14, 15a) enables the weft yarn to be retained gently in a reduced space.
