The shuttleless loom is a new loom which is born after the shuttle loom. The shuttleless loom has the advantages of light weight, small vibration, low noise, high speed, high efficiency, etc. and occupies the loom market rapidly. The common basic feature of shuttleless looms is that the weft yarn packages are separated from the shuttles, or that only a small number of weft yarns are carried in place of a large and heavy shuttle with a small and light weft insertion device, providing advantageous conditions for high-speed weft insertion. In the weft yarn feeding process, a bobbin is directly adopted for winding, and the weft yarn enters the weft insertion mechanism through the weft storage device, so that the loom gets rid of frequent weft-supplementing actions.
The selvedge device is required to be used for adjusting and limiting the selvedge in the weaving process of the shuttleless loom so as to effectively assist the selvedge of the woven fabric of the shuttleless loom to resist external acting force and prevent the selvedge from being scattered, but the acting force of the selvedge device woven by the conventional shuttleless loom on the selvedge device is mainly changed in a bolt adjusting mode, so that the selvedge device cannot be effectively applied to different selvedge tensions in the actual weaving process, further the acting effect of the selvedge device is reduced, the situation that the woven fabric of the shuttleless loom is bad to weave is easy to occur, and the economic benefit of the shuttleless loom is reduced.
