Swivel reed loom with pneumatic weft injection - moves weft injector nozzle to keep it aligned with fell line until beating up completed

摘要

The arrangement is intended for a weaving loom with pneumatic weft injection via a nozzle. The nozzle is carried by a parallel rod which is coupled to the reed such that the nozzle is moved to remain aligned with the injected weft thread from the moment of injection until this thread is beaten up to the fell of the fabric. This coupling may comprise two pairs of levers and which swivel about the swivel axis of the reed cylinder and carry the nozzle, one lever being pivoted to one end of a swivel arm whose other end is pivoted to a fixed point, or to the end of a cam operated swivel lever pivoted to a fixed point. Mechanism controls movement of weft injection nozzle in air jet loom. The arrangement maintains alignment of the nozzle with the fell line when the weft thread guide channel formed by fingers on the reed is withdrawn as the reed swivels up the weft. FL.
