AN IMPROVED WEFT SUPPLIER, PARTICULARLY FOR FLUID-JET LOOMS

摘要

The weft supplier comprises a stationary drum (TA) covered with anonreflective coating for purposes of surface hardening, a swivelarm (BR), for winding a plurality of loops of yarn (F) on the drum (TA) for building a weft stock (RT). In order to count the loops released at each weft insertion, a light source (SL) generates a light beam (r) that is received by a photocell (CF) after reflection on a mirror-polished metal plate (ER) set in the external surface of said drum (TA).
