How Projectile Loom Makes Weaving Patterns

Projectile Loom for Weaving Patterns:

Projectile Loom makes weaving patterns for looming in textile industry. The loom follows weaving techniques those use a projectile equipped with a gripper to carrying weft yarn across the shed is called projectile loom. It allows the insertion of practically any yarn such as cotton, wool, polypropylene ribbon, mono and multifilament yarns, jute and linen.

Features of Projectile Loom for Weaving Techniques:

The features of different looms with weaving techniques is stated here-

• Projectile receiving units are different looms from the stirring sley whe the sley carries the reed & gripper guides,
• The gripper projectile made with fine steel to help for making nice weaving patterns
• For the duration of its flight through the shed of the projectile runs in a rake likes steel guides as a result the warp threads are touched neither by the projectile nor weft thread,
• Generally the gripper projectile is selected across the warp shed on very high speed  where the picking energy derived from the energy stored in a metal torsion bar that is twisted for different looms
• All picks are cut off at the picking side near the selvedge after weft insertion for the loom
• The color changing machinery is less complicated for making weaving patterns
• The weft is marked directly from a large stationary cross wound package.
• The reed is not joint as in a shuttle the loom but rocked about its axis by the pair of cam.
• The reed & projectile guides are stationary for the duration of pick insertion.
• Small shed opening because of the smaller size projectile. [2]

Quality management of bead loom patterns

In aut garments quality management system of bead loom patterns are independent. The quality assurance department is assigned to maintain consistently uniform quality of the material in process & various stages of its manufacturing.

Why quality is important?

Quality sells brand reputation or image (Levis, Nike etc). No quality means no order. No order means no production. Customer’s satisfaction to the products. The products must look good to attach consumer’s attraction. If the product is dirty madder no proper packing consumers will not give it a second look.

How to control quality:

Quality controls or quality assurances must have the knowledge to do the checking. He must have the proper quality assurance package & the Audit from or inspection report. Process of checking from cutting of fabrics to finished package.

Jacquard to be checked for defects (no shading, bowing, slubs, broken picks, hole etc)

In line inspection roving & checking on all sewing operation & document the defects. Take immediate action to correct & fix the defects or problems. Sewing machine has problem causing puckering, skip stitch, needle break so check it. The sewing worker should stop sewing.

Quality control chief should receive the audit report of the quality controller in a timely manner. May be one hour interval to ensure the quality of the operation is under control. If there is quality issue quality controller chief should take the matter to the factory manager for him to follow up with the sewing operators for action & correction line supervision should stay with the sewing operator to ensure that the quality is maintained & no more defects.

Factory manager must connected with inventory department for all the trims, accessories for the production.

Objective of quality control:

• Research
• Selection of raw material
• Process control
• Process development
• Product testing
• Specification check

Accessory of weaving patterns Inspection Procedure

The following level should be applied:

• For countable items (such as labels, buttons etc.)
• For non-countable items (such as interlining, ribbons etc.): At least 10% of order quantity with an acceptable defect rate of 2%.
• If any accessories fail the first inspection, then a second inspection is to be carried out and if the second inspection fails again then the factory must immediately notify the concerned product controller at Auto weaving patterns ltd. At the same time the factory should notify the relevant supplier immediately for any necessary corrective action / replacement if required.

Advantages of the Loom for looming:

Advantages of the loom with weaving techniques is given below-

As the projectile is passing through guides and there is no reed to projectile or projectile to yarn contact.

More than one cloth can be woven simultaneously with different looms for looming[2]
