<p>Yarn (3) feed system treading-up appts., specifically for a weft supply system of a loom (7), in which an intake brake (2) precedes a regulator (1) and threading-up is effected by a controlled (14) pneumatic ejector (29,30) incorporated in the intake brake (2). The regulator (1) has a winder (16) for weft from a spool (4), and specifically weft braking elements (2c,2d) are made inoperative during threading-up by control units (10-14). Pref. the regulator (1) has a weft storage section (17), e.g. a windings storage drum and flyer.</p> |
