For weaving machines, drop pins and dropper pins are important components used in various mechanical systems to control the movement of warp threads, shuttle guides, and other related processes.

Here are some specifications typically found for drop pins and dropper pins used in weaving machines:

1. Drop Pins:

Drop pins are used to maintain the position of elements in a weaving machine, such as the shuttle box or guide mechanisms. These pins are crucial in the accurate movement and operation of the machine.

• Material: High-quality steel or stainless steel, often with coatings like chrome or nickel for durability and wear resistance.
• Tolerance: Precision tolerance is essential, often within 0.1mm for smooth operation.
• Function: To lock or release mechanisms, typically used in shuttle control or stop motions in shuttle looms.

2. Dropper Pins:

Dropper pins are part of the mechanism that controls the shedding of threads and are typically found in shuttleless looms or machines with automatic shedding devices. These pins help ensure that the warp threads are lifted and lowered at precise intervals during the weaving cycle.

• Material: Similar to drop pins, dropper pins are made from durable, high-strength materials such as carbon steel, stainless steel, or special alloys that resist bending and corrosion.
• Diameter: Usually between 4mm and 8mm.
• Length: The length can vary from 30mm to 100mm, depending on the design of the machine.
• Shape: Often designed to fit into specific cam or control mechanisms that regulate the shedding motion.
• Surface Finish: Typically, these pins undergo processes like heat treatment to improve their wear resistance and provide a smooth surface for operation.
• Tolerance: As with drop pins, high precision is required, typically within 0.1mm to 0.5mm tolerance.
• Function: Control the lifting and lowering of warp threads in shuttleless looms, particularly in the shedding motion.

Notes for Both Types of Pins:

• Heat Treatment: Both drop pins and dropper pins undergo heat treatment to ensure they can withstand high mechanical loads and wear.
• Coating: Some pins may have a coating, such as zinc, nickel, or chrome, to reduce friction and enhance longevity.
• Compatibility: Pins are usually designed to fit specific models or brands of weaving machines, so specifications must match the manufacturer's requirements.

Our electronic weft selector can be applied in high speed rapier loom with speed upto 400r/min.

Rapier looms have been developing at a fast speed, and in this background, our company developed the high speed electronic weft selector. It is very simple in structure, reliable in function and extensive in application. The weft selector can be applied to high speed, medium speed and low speed rapier looms. Its maximum speed reaches 600rpm. The modular design makes it possible for customers to choose 2, 4, 6, 8, color at will. No special maintenance or lubrication is need, and it is easy to change or add color. This model is the best choice for rapier looms with only 1/3 price of European model and reliable quality. It is originally applied on the rapier looms manufactured in Kingtex, Wanli, Titan, Rifa, Suzhou Picanol.

Additional Information:

• Production Capacity: 50 PCS
• Delivery Time: 05 to 06 Days.
