Weft knitting machine having movable sinker

摘要

A weft knitting machine having a movable sinker capable of securing a large space at a needle bed near a knitting fabric knitting area and making a pause in the state of stopping action on the knitting fabric knitting area. A sinker operating cam mechanism ( 10 ) installed in a carriage acts on the butt ( 12 c) of a sinker jack ( 12 ) to move the sinker jack ( 12 ) backward from a mouth part ( 2 ) so that the acting part ( 8 c) of the movable sinker ( 8 ) can retract from the mouth part ( 2 ). The sinker jack ( 12 ) is locked to a moved back position by a locking mechanism ( 16 ). Since a wire ( 17 ) passed through a needle plate ( 5 ) is utilized to lock the sinker jack ( 12 ) in the locking mechanism ( 16 ), the locking mechanism ( 16 ) can be reduced in size. To lock the sinker jack ( 12 ) to the wire ( 17 ), the sinker jack ( 12 ) comprises a projection ( 12 f).
