Fabric Spreader on Knitting Machine

A fabric spreader for circular knitting machines is designed to keep knitted fabrics even and well-tensioned. It has adjustable wings that can expand and move with the knitting process. The wings are supported on a frame and equipped with adjustable springs to match the force from the knitted goods being collected.

The main points about the purpose of a fabric spreader for knitted goods on a circular knitting machine are:

  1. Ensures Even Spreading: The fabric spreader’s primary purpose is to distribute the knitted fabric evenly as it is being produced, helping to avoid any irregularities or uneven areas.
  2. Maintains Proper Tension: It applies adjustable spring-loaded tension to the fabric, keeping it appropriately stretched and preventing excessive stretching or sagging during the knitting process.
  3. Prevents Distortions: By controlling the spreading and tension, the fabric spreader helps to avoid distortions, creases, or folds in the fabric, leading to higher-quality finished products.
  4. Accommodates Different Fabrics: The adjustable features of the spreader, such as expanding wings and spring tension, allow it to handle various fabric sizes and properties effectively.
  5. Essential for Circular Knitting Machines: Fabric spreaders are crucial components in circular knitting machines, especially when producing tubular fabrics like socks, stockings, and seamless garments.

The fabric spreader for knitted goods on a circular knitting machine works as follows:

  1. Mounting on the Circular Knitting Machine: The fabric spreader is attached to the circular knitting machine, typically near the area where the knitted fabric is being taken up or collected. It may be secured to the machine frame or other designated mounting points.
  2. Expanding Wings Adjustment: Before starting the knitting process, the expanding wings of the fabric spreader are adjusted to match the desired width or diameter of the knitted fabric. This adjustment ensures that the fabric spreader can accommodate the specific size of the fabric being produced.
  3. Pivotable Support and Spring-Loading: The expanding wings are pivotably supported on the fabric spreader frame, allowing them to move and follow the circular knitting path. This allows the fabric spreader to maintain consistent tension as the fabric is produced in a circular shape.
  4. Adjustable Spring-Loaded Mechanism: The expanding wings are equipped with adjustable spring-loaded mechanisms. These springs are designed to provide the necessary tension to the fabric as it is being taken up by the knitting machine. The force generated by the knitted goods pulls against the fabric spreader’s spring-loaded wings.
  5. Tension Control: As the knitted goods are taken up by the machine, the expanding wings apply tension to the fabric. The spring-loaded mechanism allows the fabric spreader to control the tension applied to the fabric, preventing excessive stretching or distortion.
  6. Even Fabric Spread: The combination of the pivotable support, adjustable wings, and spring-loaded mechanism ensures that the fabric spreader maintains even tension across the width or diameter of the fabric. This results in uniform fabric spread and helps to prevent any creases or folds that might otherwise occur during the knitting process.
  7. Continuous Operation: The fabric spreader operates continuously as the circular knitting machine produces the fabric. The fabric spreader’s role is to keep the fabric evenly spread and tensioned during the entire knitting process.
