Ultra-wide side Tucked-in selvage apparatus
Technical field
The invention belongs to loom auxiliary equipment technical field, more particularly, to a kind of ultra-wide side Tucked-in selvage apparatus.
Background technology
The rotation that waste selvage scissors mechanism is matched with by crochet hook when Tucked-in selvage apparatus are weaved forms a hook yarn process.In hook
During yarn, crochet hook passes through top line and through grip slipper rear, and then grip slipper is upturned and bounces back backward, makes crochet hook
Hook has been suffered and has been clipped in the weft yarn accommodated between elevating lever and grip slipper, and then crochet hook is back swung with weft yarn, is swung to certain
During angle, the blessing elevating lever of lower section will be pressed downward by the briquetting of crochet hook bar front end, while elevating lever relieving weft yarn is accommodated
Grip slipper can also turn forward, and above the weft yarn passed through from upper and lower shear blade is cut off by shear blade for drive, and then crochet hook continues with weft yarn
Back rotation is taken weft yarn out of top line until crochet hook and departs from the range that crochet hook reaches crochet hook, in the process of crochet hook hook yarn
In, the distance between waste selvage scissors and blessing elevating mechanism, the length of crochet hook insertion fell part determine the width of tuck-in selvage.
To adapt to the woven requirement of broadside, waste selvage scissors mechanism and crochet hook insertion fell portion are have modified on the basis of former Tucked-in selvage apparatus
The length divided, to reach the requirement of broadside tuck-in selvage.
