Parts of double jersey knitting machines
Circular knitting machines usually have parts such as cylinders, needles, feeders, cams, cam boxes, take up rollers, yarn tensioners, yarn guides, creels, base plates, auto Stoppers, VDQ pulleys, bodies, sinkers, etc.
Needle
A needle can knit the fabric, which is one of the main parts of circular knitting machines. A needle includes a bearded needle, a latch needle and a compound needle and a latch needle is the most used.
Latch needles
A latch needle is a steel needle which has a butt at one end and a short hook closed by a latch at the other. A needle with high speeds can improve productivity.
A latch needle consists of a latch, a curved hook, a tumbler which swings on a rivet under the hook, stem and butt, which is applied to raschel and crochet machines. It can be referred to as an automatic needle sometimes because a presser is not required. The pressure of a completed loop on the latch closes the hook as the latch rises on the shaft.

Advantages of latch needles
Latch needles ensure that the fabric has good quality and productivity can be effectively improved by high speeds.
Latch needles save energy, thus reducing manufacturing costs.

Features of latch needles
It has a wide application in the field of weft knitting.
It is more expensive compared with the bearded needle.
It is automatic or loop controlled.
It can work at any angle.
The depth of the needle determines the length of the loop.
The change in reciprocal height produces knitting, tuck, or missed stitch.

Positive Feeder
A positive feeder is applied to stabilizing and adjusting the tension of the yarn feed. The self-cleaning tension ring is impressed on the wear-free yarn feed wheel and yarn infeed tensioner by the MPF L.
Advantages of positive feeders
A positive feeder has the advantages of easy use, easy maintenance, wear resistance and long service life. The self-cleaning vibrating yarn tensioner can avoid breaking down the circular knitting machine, thus improving productivity. The tension force is even because of the magnetic tension ring.
Features of positive feeders
Vibration tension devices
The vibrating tension disc rotates opposite the direction of the yarn feed, effectively preventing the dirt from accumulating on the tension disc, which is referred to as self-cleaning.
Enclosed storage feed rollers
The accumulation of residual yarn is avoided due to enclose and wear-resistant feed rollers and yarn storage while dealing with the multifilament yarn.
Built-in anti-residue device
When the multi-filament yarn is processed, capillary filaments will accumulate on the yarn storage roller, which will affect smooth yarn feeding. When weaving short-fiber yarn, users can output the yarn at a flat and shallow angle. When using multi-filament filaments, they can choose to output the yarn at a steeper angle to prevent accumulating the residual yarn.
Yarn feeding cantilevers
The yarn-feeding guide arm doesn’t need to be installed on the upper edge of the yarn-feeding machine due to this structure, and the replacement of the belt becomes faster and more convenient.

Lycra Feeder
The tension of the spandex feed is stabilized and adjusted by the lycra feeder.
Features of lycra feeder
A mechanical lever is used for the yarn breaking automatic stop device. According to the spandex’s tension, the counterbalance can be changed. The light path will be blocked and the yarn breaking stop signal triggered after the yarn breaks.
High-precision yarn feeding can be obtained because of all-metal shells and integrated wire feeding rollers, so that the quality of the fabric can be good.
The position of breakage of the yarn can be found easily due to the integrated LED indicator light, resulting in high work efficiency.
The breakage of the yarn can be analyzed by the optical technology and a reminder will be sent.

Cam
A cam is a crucial part of the knitting machine, which transmits the force to the needle bar and makes it move in a regular manner. In the fields of textiles, light industry, and mechanical transmission, cams are often applied. Different complicated regular movements can be achieved by using cams with different contours and grooves.
The features of cams
There are anti-oxidation layers, wear-resistant layers, waterproof layers and protective paint layers on the surface of the cam.
The cam is easy to be used and the labor intensity of the user is reduced.
The complex knitting motion is driven by a simple structure, resulting in a significant improvement in knitting.
The cam adopts a simple structure and is made from common materials, saving overall costs.

Cam box
A cam box has the function of holding the cam based on the design of the fabric.
Creel
Creel is used to put the yarn cone where the yarn is transported to the machine through the pipe.
Auto Stopper
If the knitting machine malfunctions, the automatic stopper will automatically stop the knitting machine.
VDQ pulley
VDQ is the variable dia of the quality pulley, which has control of the quality of the fabric and is essential for keeping appropriate stitch length.
The cloth rolling machine
Features of the cloth rolling machine
It has multi-step changing speeds and an intensive average of changing speed with no speed repetition. There is a large pack-up cloth extent, which is easy to use.
The wet lubricant was adopted for the machine's gear case, which is easy to maintain and not susceptible to wear.
The size and tightness of the cloth can be fixed by the machine, and the needle's service life can be longer.
By using this machine, the cloth shows no difference in starting and ending stripe distance and yard weight.
The cloth rolling machine can record with graduation while producing.
Adjustments can be made based on previous records.

Cylinder
As the main component of a knitting machine, the adjustment of the cylinder is important. The cylinder is equipped with a needle, sinker, cam, and others. They have features of high accuracy, good wear resistance and long service life. The gauges are between 14 and 44, which are applied to single-jersey and double-jersey machines. More requirements are put forward for processing iron accessories. They need to be kept in the open air before processing. This will release the internal stress of the iron parts, thus reducing expansion caused by heat and contraction caused by cold and mechanical deformation of the iron parts. More importantly, accuracy and long service life will be improved.
The features of cylinders
Product with good quality is guaranteed by using steel-slice from Taiwan when the cylinder is running at high speed.
High-impact materials from Japan and Europe are used to ensure stabilization.
Special circulation heat treatment is adopted to ensure the balance and consistency of quenching rigidity of cylinders.
Increase turnout and reduce cotton wool cumulus and times of cleaning to match the dust hole treatment.
Vertical grinding machine is used for rubbing to make the cylinder’s plow groove smooth.

Fabric
Double jersey fabric
Double jersey fabrics are similar to single jersey fabrics, but they are knit by two sets of needles. The difference is that the two sides of a double jersey fabric are the same.
