Primary knitting elements

Needle:

The needles are the most important stitch forming elements. They are displaced vertically up and down and are mounted into the tricks or cuts of the knitting cylinder.

There are three types of needles namely:

1) Latch Needle.

2) Spring bearded Needle and

3) Compound Needle.

The main function of needle is loop formation.

Cams:

Cam is the second primary knitting element. The cams are the mechanical device which convert the rotary machine drive into a suitable reciprocating action for the needles or other elements came are carefully profiled to produce precisely time movement and dwell periods.

Types of knit cam:

1. Knit cam
2. Tuck cam
3. Miss cam

Sinker:

Sinker is a thin metal plate with action at right angles to and fro between adjoining needles.

Functions of Sinker:

• Loop formation: The main objects of a sinker are to assist the needles in loop formation by sinking or knitting the newly laid yarns into a loop.
• Holding down: It also holds down the loops at a lower level of the needles stems and prevents the old loops from being lifted as the needles raise to clear them for their hooks.
• Knocking over: The function is knocking over at which the needle passes through the old loop by drawing a new loop.
