Passaro Exports based in Chennai, India is a leading dealer and exporter of used power looms. The loom is a machine or device which is used to produce the woven fabric. It is the central point of the whole process of cloth production. In other words, a loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing handlooms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom. The main task of looms is to clutch the twist threads under pressure to enable the progress of the interweaving of the woof strands. The loom’s system and exact form can diner to some extent; however it still performs the basic application.
They deal with the following type of used power looms:
- Air jet loom
- Water jet loom
- Rapier loom
- Projectile/Missile loom
- Multiphase loom
USED POWER LOOMS – WEFT INSERTION
Different types of looms are most often defined by the way that the weft, or pick, is inserted into the warp. Many advances in weft insertion have been made in order to make manufactured cloth more cost effective. There are five main types of weft insertion and they are as follows:
Used Shuttle Power Looms
The first-ever powered looms were shuttle-type looms. Spools of weft are unravelled as the shuttle travels across the shed. This is very similar to projectile methods of weaving, except that the weft spool is stored on the shuttle. These looms are considered obsolete in modern industrial fabric manufacturing because they can only reach a maximum of 300 picks per minute.
Used Air Jet Power Looms
An air-jet loom uses short quick bursts of compressed air to propel the weft through the shed in order to complete the weave. Air jets are the fastest traditional method of weaving in modern manufacturing and they are able to achieve up to 1,500 picks per minute. However, the amounts of compressed air required to run these looms, as well as the complexity in the way the air jets are positioned, make them more costly than other looms.
Used Water Jet Power Looms
Water-jet looms use the same principle as air-jet looms, but they take advantage of pressurized water to propel the weft. The advantage of this type of weaving is that water power is cheaper where water is directly available on site. Picks per minute can reach as high as 1,000.
Rapier Looms
This type of weaving is very versatile, in that rapier looms can weave using a large variety of threads. There are several types of rapiers, but they all use a hook system attached to a rod or metal band to pass the pick across the shed. These machines regularly reach 700 picks per minute in normal production.
Projectile Looms
Projectile looms utilize an object that is propelled across the shed, usually by spring power, and is guided across the width of the cloth by a series of reeds. The projectile is then removed from the weft fibre and it is returned to the opposite side of the machine so it can be reused. Multiple projectiles are in use in order to increase the pick speed. Maximum speeds on these machines can be as high as 1,050 ppm.
