Background
There are various classifications of weaving machines. The textile fibers can be classified into cotton, wool, hemp, silk, and the like. For example, the classification according to the weft insertion method of weaving can be divided into two main categories of shuttle weaving machines and shuttleless weaving machines.
A shuttle loom is a loom that uses a conventional shuttle (wood shuttle or plastic shuttle) for weft insertion. The shuttle is large in size and heavy in weight, is repeatedly projected to and from the shuttle, and is large in vibration, high in noise, slow in speed and low in efficiency.
A shuttleless loom is a new type of loom produced following a shuttle loom. The shuttleless loom has the advantages of light weight, small vibration, low noise, high speed, high efficiency and the like, and quickly occupies the loom market.
The weft insertion modes of shuttleless looms are various and include rapier, jet (air jet, water jet), gripper, multi-shed (multi-phase), weaving and the like. The rapier loom clamps and guides the weft yarn with a rigid or flexible rapier head and a belt. The rapier loom is suitable for weaving plain weave and grain fabric, and is characterized by convenient color change, suitability for multicolor weft fabrics, and suitability for the production of yarn-dyed fabrics, double-layer pile fabrics, pile fabrics and decorative fabrics.
There is a shuttleless loom in the market, in which a weft bobbin is mounted on a weft bobbin support, and when unwinding, the weft is pulled out from the side of the weft bobbin and into the loom. When the vehicle is parked, the weft loses tension and naturally falls under the action of gravity, so that a parking stop is caused.
