A warp-weighted loom (see diagram) typically uses a heddle-bar, or several. Weft feeder feed the yarn to the projectile. Rapier looms use long rapiers or double rapiers to carry the weft across the loom. Projectile looms insert weft using a bullet-like projectile and have advantages like higher speeds, less wear on threads, and ability to weave multiple fabrics at once. Hence, different parts of a projectile weaving machine facilitate the weaving process. Projectile looms insert weft using a bullet-like projectile and have advantages like higher speeds, less wear on The basic diagram of a winding machine shows three sections: the unwinding zone, tension and clearing zone, and winding zone. 3 minutes, and the fastest would take just 1. Projectile Weaving Machine or Loom: Projectile weaving machine is a shuttleless loom method for filling yarn insertion using a small metal device resembling a bullet in Projectile weaving machine or loom uses a projectile equipped with a gripper to insert the wept in the warp shed instead of a regular shuttle. - Projectile looms produce fabrics with good quality at high efficiency and low energy use. Operators must stay clear of all moving parts and notify assistants immediately in case of any accidents. The cost of a 340cm-width new pro­jectile loom (P7300 HP) is approximately Rs. It describes the torsion bar picking mechanism of projectile The first projectile takes and holds in its back the weft in form of a tail; then, pushed by the release of the projectile thrower, it passes through the shed and deposits the weft inside the warp; subsequently the projectile falls A projectile loom is a shuttle less loom. It is specifically designed to accelerate projectile to speed of 25 m / s. Fig: Rapier Loom and Projectile Loom. The diagram depicts the start and end of each primary event of different weaving motions.

The projectile loom has the advantages of stable weft insertion, good fabric quality, and less waste yarn. Despite having such benefits of usage and lower price, shuttle-based Loom has some The document provides diagrams of loom parts and motions to illustrate how yarns are interlaced to form woven fabric on the machine. It is possible to achieve weaving performances with breakage rate per square meter of cloth. 1 The overall hardware structure of the . In the projective weaving machine, the entire concept of picking is different from the conventional picking mechanism. So, calculation play an important role in weaving process. Shuttle looms denim weaving projectile selvedge heddels shuttles textiles wertheim tear bobbinWeaving workshop Describes about the picking mechanism in weaving machine and types of picking in shuttle and projectile loom. Diagrams show the mechanism and fabric path through a blanket and tube compactor machine. 3. SHUTTLELESS LOOMS Fig 3. The weaving industry is being modernized by replacing shuttle looms with shuttleless looms. Projectile is pick across shed. [1] The projectile is propelled through the warp shed using a metal torsion rod to grip and carry the weft. Due to this - Projectile looms produce fabrics with good quality at high efficiency and low energy use. Here, the weft is inserted by a much smaller bullet like shuttle or carrier about 90 mm long and weighing about 40 grams. txt) or read online for free. 2 A diagram of the projectile weaving. The projectile is then removed from the weft fibre and it is Specific modern loom types discussed include rapier, air jet, water jet, and projectile looms, which utilize different automated processes for inserting the weft through the warp shed. They are the costliest looms. 1 : Partially guided solid carrier; 3. The main parts described are the compound needle, pattern chain, needle bar, and more.

It has two upright posts (C); Projectile: 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 picking system involves many sub-mechanisms. 2: Shuttle High energy consumption in air-jet looms increases the cost of fabric which would be the reason for less popularity of air-jet weaving compared to other shuttle-less loom (e. ) Picking The projectile loom uses a bullet-like shuttle called a projectile to insert the weft thread. 1, which shows the main units and mechanisms, where denoted: #1—the drive of mechanism for pushing of projectile weft from right receiving box; #2—the drive of mechanisms of right receiving box; . Weft from weft accumulator is unwound so as to give There are various types of loom like Projectile loom, Rapier loom, Air jet & Water jet loom etc. 2. Success in a modern weaving plant is the ability to have easy substitutability of product and to move The projectile weaving machine made its appearance in the market at the beginning of the 50’s and is today still used in the whole world. The advantage of bottom closed shed is to achieve high cover factor at the cost of high power consumption and wear and tear of weaving parts. The whole process of weaving is done through several motions. 2 : Fully guided solid carrier; 3. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads.
