Frequently Asked Questions | FAQs
What is projectile loom ?
A projectile loom is a type of mechanical loom that uses projectiles, also known as shedding mechanisms, to separate the warp threads and allow the weft threads to be woven in. This type of loom is known for its ability to produce high-quality, high-speed weaving. The projectiles are small, dense objects, such as metal rods or shuttles, that are propelled through the warp threads to create an opening, or shed, for the weft thread to pass through. This process is repeated rapidly, allowing the weft thread to be woven in and the fabric to be created. Projectile looms are widely used in the textile industry to produce a variety of fabric types, including cotton, wool, and synthetic fabrics. They are also known for their durability, efficiency, and versatility.
What is torsion rod in loom ?
In a loom, a torsion rod is a component used to provide stability and support to the shedding mechanism. A shedding mechanism is a device that separates the warp threads to allow the weft thread to be woven in. The torsion rod is responsible for maintaining the proper tension in the shedding mechanism, and helps to ensure that the shedding mechanism operates smoothly and consistently. The torsion rod is typically mounted in a twisted or torqued position, and its shape and strength are designed to resist the twisting forces that are generated during the weaving process. Torsion rods play an important role in the overall performance and efficiency of a loom, and can impact the quality and consistency of the woven fabric.
