Pneumatic High Foot Thread Circular Knitting Machine

Pneumatic High Foot Thread Knitting Machine – Technical Specifications

• Model: 34'' 60G 18F

• Diameter: 1.9 meters

• Gauge: 60G (60 needles per inch)

• Number of Feeders: 18 feeders

• Weight: 2.5 tons

• Speed: 20 revolutions per minute (RPM)

This machine is engineered for precision knitting of high-density threaded fabrics, particularly for garment components such as collars, cuffs, and waistbands. The 60-gauge configuration provides an ultra-fine knitting structure, making it ideal for detailed, elastic trim production. With a 1.9-meter diameter and 18 yarn feeders, it offers stable and efficient output, while the pneumatic high foot design allows it to handle thicker or specialty yarns with ease. The 2.5-ton weight ensures stable operation, and the 20 RPM speed offers a balance between productivity and quality.

Pneumatic High Foot Thread Knitting Machine – Function

The Pneumatic High Foot Thread Knitting Machine is a specialized knitting machine designed for the production of special thread cloth with high precision and efficiency. It is equipped with a pneumatic (air-powered) lifting system, which allows for faster, smoother, and more stable operation compared to traditional mechanical systems.

Main Functions:

1. Knitting of Special Thread Cloth

   • Specifically engineered to handle specialty yarns and threads, including elastic, thick, or textured yarns.

   • Ensures even tension and consistent quality in complex or heavy fabrics.

2. High Foot Design for Thick Fabrics

   • The high foot clearance allows the machine to work with bulky or multi-layered fabrics, which are difficult to process on standard machines.

   • Ideal for creating structured, raised, or dimensional knit fabrics.

3. Pneumatic Control System

   • Uses compressed air to control lifting and pressing movements with precision and speed.

   • Reduces manual adjustments, improves production efficiency, and minimizes mechanical wear.

4. Versatile Fabric Creation

   • Capable of producing ribbed, threaded, or textured fabrics used in specialized garments or functional textiles.

Application of the Pneumatic High Foot Thread Knitting Machine

The Pneumatic High Foot Thread Knitting Machine is widely used in the garment manufacturing industry for the production of threaded components that require elasticity, durability, and a clean finish. Its advanced pneumatic system and high foot design make it particularly suitable for creating detailed, structured knit parts used in various sections of clothing.

Key Applications in Garment Production:

1. Thread Collars (Knitted Collars)

   • Produces elastic and form-fitting collars for t-shirts, polo shirts, jackets, and sweaters.

   • Offers excellent shape retention and stretchability for comfort and durability.

2. Thread Edges (Cuffs and Hems)

   • Used to knit ribbed or threaded edges for sleeves, bottom hems, and necklines.

   • Ensures a snug fit and prevents fabric from rolling or fraying.

3. Thread Waistbands

   • Ideal for producing waistbands for sportswear, casual pants, skirts, and undergarments.

   • Provides the necessary flexibility and support for active movement and daily wear.

Additional Benefits:

• Consistent quality for mass production

• Capable of handling specialty yarns and elastic threads

• Smooth, efficient operation with reduced manual effort thanks to pneumatic lifting
