Description

Technical Field

[0001] The utility model relates to weaving, in particular to a yarn guide frame of a loom. Background Art

[0002] In textile equipment, the yarn is generally not fed directly into the corresponding equipment after being guided, but a weft feeder is set between the spindle and the equipment. The weft feeder first reels and stores part of the yarn from the spindle, and the equipment then draws the yarn from the weft feeder for use. When the yarn stored on the weft feeder decreases to a certain level, the weft feeder will restart and reel in and store the yarn from the spindle. The addition of a weft feeder allows the yarn to be fed into the corresponding equipment more smoothly and stably, especially for warp knitting machines, circular machines and other weaving looms. Generally, a yarn guide frame is designed, and multiple weft feeders are installed on the yarn guide frame for use. The existing problems with this type of yarn guide frame include: the position of the weft feeder cannot be adjusted, and the scope of application is small. Utility Model Content
