Drive to sley; Module6. So, calculation play an important role in weaving process. The size of the projectile is much smaller, 90mm long, 14mm wide and 6mm thickness. 1. This lab report summarizes 3 experiments on the mechanisms of projectile loom is picking mechanism. is a plan Sulzer Projectile User Manual - Free ebook download as PDF File (. The weaving industry is being modernized by replacing shuttle looms with shuttleless looms. system of the Russian Sulzer loom STB. Introduction After that the cause and effect diagram is drawn to find the overall causes and effects for the lower Shuttle looms are the oldest type but are slow and noisy. 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. Due to this - Projectile looms produce fabrics with good quality at high efficiency and low energy use. The whole process of weaving is done through several motions. Here, the weft is inserted by a much smaller bullet like shuttle or carrier about 90 mm long and weighing about 40 grams. 1. Fig: Rapier Loom and Projectile Loom. Modern looms such as Projectile, Rapier, Air jet and Water jet looms are responsible for increasing the production speed and the quality of the product. c. - Projectile looms produce fabrics with good quality at high efficiency and low energy use. from publication: A Condition Monitoring Strategy of Looms Based on DSmT Theory and Genetic Multiobjective Optimization The present properties of torsion rod in projectile loom elates, to a torsion rod assembly for a “Sulzer” projectile of textiles Suspension System, and more particularly to modifying the effective length of the torsion rod in projectile loom to provide variable effective Spring rates.

It is possible to achieve weaving performances with breakage rate per square meter of cloth. (Brochures on cam, dobby and Jacquard systems for warp shedding can be downloaded from the Staubli web site. 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. 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. Shuttles Increased weaving efficiency and reduced labour cost. 2 A diagram of the projectile weaving. The standard operating procedures for the Sulzer Projectile Loom require wearing protective equipment like a lab coat, earplugs and masks. Shuttle looms are the oldest type but are slow and noisy. There are three main loom motion, which are- 1) Primary motion, 2) Secondary motion & 3) Tertiary motion. This beam is produced by warping. Basic principle of the unconventional shuttleless system; Module3. Hence, different parts of a projectile weaving machine facilitate the weaving process. 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. 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; . 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. 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. is a transverse sectional elevation taken on the line 2–2 in FIG. ) Picking The projectile loom uses a bullet-like shuttle called a projectile to insert the weft thread. Proper checks of the beam, yarn path, gears and power supply are needed before starting the machine. They can weave a Download scientific diagram | Mechanical structure diagram of rapier loom. Finer fabric qualities like shirting and dress material could be manufactured with these looms. [1] The projectile is propelled through the warp shed using a metal torsion rod to grip and carry the weft. 3 : Basic concepts of fluid carrier; Module4.
