Weft selvage tuck-in nozzle injection timing apparatus

摘要

A tuck-in apparatus for producing a fastened tuck-in-selvage includes a tuck-in nozzle for injecting air into a warp shed from the outside of a warp array in order to fold back a weft yarn end toward a cloth fell. A selvage-fastening nozzle is disposed adjacent to the cloth fell outside the warp array for causing the weft yarn end folded back by the tuck-in nozzle to extend along the cloth fell. Timing control is provided to provide a first period of air injection from the tuck-in nozzle and a second period of air injection from the selvage-fastening nozzle so that the beginning of the second period is later than the beginning of the first period, and the second period ends before the warp shed is closed.
