Knitting Elements of Tricot Warp Knitting Machine
Introduction:
The knitting elements are located on four different bars and produce the rows of stitches in a pre-determined, precisely coordinated and simultaneous series of movements. Every knitting element has its own corresponding movement.
The knitting elements of the tricot warp knitting machine are described as follows,
Needle:
Modern Tricot warp knitting machines, apart from a small number, are constructed with compound needles. The bearded needle, which until recently dominated the field of tricot knitting, can still be found running efficiently and reliably in thousands of machines around the world. Its knitting action is, however, non harmonic, and so imposed many limitations on the machine builders.
The compound needle used today in the construction of Tricot machines. The needle is made of two separate parts; the main part of the needle, which includes stem, butt and hook, and the closing element which operates with a sliding up-and-down movement in a groove, cut into the stem of the main part of the needle.
The needles are set in tricks cut in the needle bed of the machine, while the closing elements, being cast in units half an inch long, are set in a separate bar. The casting of the closing elements is required to ensure perfectly curate spacing between them.
Sinker:
The sinker is a thin plate of metal which is placed between each needle. The sinkers are usually cast in units, one inch long, which in turn are screwed into the sinker bar.
Different names are given to different parts of the sinker according to their operation. The neb of the sinker (1) and throat (2)are used to hold down the fabric while the belly of the sinker (3) is used as a knocking-over platform.
Guides and Guide Bars:
Each end of yarn from each warp is located in the knitting zone by passing through the eye of a guide. All the guides containing the yarns fed from connected to a guide bar, so that all of them move uniformly with it.
The individual guides are usually cast in one inch units which in turn are fitted on the guide bars. The guides swing between and around the needles in order to wrap the yarn around them to form a new loop. They also shog side ways to connected the wales into a fabric.
Tricot machines are produced with 2, 3, or 4 guide bars, an arrangement which requires the same number of warps to be used. Tricot machines with a larger number of guide bars are produced in very small numbers.
