What kind of loom is used for 6 or 7 count yarn weaving sofas? There is a shuttle, or what

Weave a sofa with 6 or 7 count of yarn, either on a rapier loom or on a shuttle loom; Mass production can also be made with an air-jet loom first.

Because four colors of weft yarn are required, rapier looms (or air-jet looms) should be equipped with more than 4 weft feeders per machine, and shuttle looms should be multi-shuttle looms.

Now the domestic multi-shuttle automatic shuttle loom has been very little production, if the second-hand loom is selected, you can choose H213 wool loom, H212 wool loom, both of these models are four shuttle boxes on the left and right sides of the 4 4 automatic shuttle loom, can be suitable for multi-color weft weaving. It is important to note that equipment equipped with dobby opening devices should be used. The H213 loom was originally designed to be equipped with 20 heald frames, generally at least 8 or more, mostly 12 16 healds.

to adapt to lattice fabrics or small jacquard fabrics with uncomplicated tissues. Jacquard sofas with complex organization should be equipped with a loom with a jacquard opening device.

This kind of 4 4 shuttle box automatic shuttle loom can make the shuttle box on the left and right sides arbitrarily lift, and even each shuttle's weft yarn can be made and woven with a single yarn. Because of the low weft count (thicker weft), the shuttle size of these two weaving machines is larger. The weft yarn can be rolled in larger quantities.

The shuttle size of the H212 loom is 424mm, 50mm, 36, 38mm; The shuttle size of the H213 loom is 467mm, 58mm, and 42mm.

The 4 4 shuttle box loom in the cotton loom is rare, mostly 1 4 shuttle box, such as GA615A or GA615A2 loom, etc., can automatically change the shuttle, but the 4 color of the 4 shuttles, each time at least to make the shuttle back and forth weaving, can not play a single weft. It can be automatically parked, and the weft should be manually replenished. The standard size of this loom is usually 343mm, if you buy a new loom, you need to be equipped with a large shuttle with a length of more than 400mm, and the second-hand old loom should be transformed on both sides of the shuttle box and casting and other parts to adapt to the operation of the large shuttle.

You can also choose second-hand hemp looms, such as J212 hemp loom, J211 hemp loom, etc., but this kind of occasion is mostly 2 2 shuttle box, if weaving 4 color fabrics, can only be relatively simple lattice fabrics, and to manually change the shuttle to supplement the weft.

There are too many rapier weaving machines to choose from, and it is recommended to choose a heavy-duty rapier weaving machine to suit low-count and heavy sofa varieties.
