Jacquard Circular Knitting Principle

Parts of the Jacquard Circular Knitting Machine:

  1. Main Cylinder: This is the main part where the knitting happens.
  2. Peg Box or Cartridge: . It’s a component where you load patterns and instructions for the knitting machine. These pegs create a single row of stitches, similar to a feeder.
  3. Needle: These are the individual elements that create the loops in the fabric.
  4. Intermediate Jack: A part that helps control the needles.
  5. Adjustable Stitch Cam and Fixed Raising Cam: These components control how high the needles go and when they come back down.
  6. Cam Box: It’s a box that contains cams (mechanical devices) to control various movements.
  7. Selector Jack: A part that selects needles.
  8. Selector Teeth: These are used for making choices on which needles to use.
  9. Pattern Jack: This is a special tool that plays a crucial role in making patterns in the fabric.

Working of the Knitting Machine:

Creating a Knit Loop: When both sides of the cartridge are empty (no patterns loaded), the knitting machine produces a basic knit loop.

Creating Tuck Loops: If there’s a pattern loaded and a pattern jack (a specific tool) is in the right slot of the cartridge, the needle moves in a clockwise direction. However, the pattern jack can disrupt this movement. When the needle tries to rise, it’s disturbed, and it doesn’t reach its clear position. This disruption results in the creation of a “tuck loop.”

Creating Missed Loops: When the pattern jack is in the left slot of the cartridge, the needle faces issues right from the start. It doesn’t rise as it should and remains in its lowest position. This causes a “missed loop” in the fabric.
