What is the knitting machine? Knitting machine parts name
A knitting machine with needles and yarn feeds organized in a circle for knitting fabrics, hosiery, sweaters, and underwear. A knitting machine is used to make knitted fabrics. The device carries and coordinates the movement of a number of mechanisms and gadgets each performing specific characteristic which contributes towards the efficiency of the knitting action.
- The body or frame either circular or rectilinear according to needle bed shape supports the bulk of the mechanisms of the machine.
- The machine driving system which coordinates the power for the drive of various gadgets and mechanisms.
- The yarn supply device or creel for holding the yarn packages, yarn tensioning gadgets, yarn feed control, and yarn feed carriers or guides.
- The knitting gadget incorporates includes the housing and driving of knitting elements in addition to the selection gadgets of the needles and garment length control gadgets.
- The material take-down mechanism.
- The attachments like stop motions, automatic lubricator, etc., highest rolling as well as first-rate of the products.

Creel means the assembly on which all the yarn packages are held in the working position with necessary guides. Two types creel used in knitting machine 1.top creel 2. Side creel
The creel, placed at the pinnacle of the machine, is called top creel. Top creel looks like an umbrella – so it’s also named as umbrella creel. When the creel is located at one side of the machine as an alternative positioning at the top of the device, the creel is referred to as side creel.
Any element or machine element on which the yarn passes applies a few tension and acts as a tensioner. But technically an attachment that is used intentionally to use and maintain preferred tension to the yarn is called yarn tensioner. The loop length and compactness of the fabric largely depends on the tension of the yarn.
Guides are there mainly to give and maintain proper route and alignment of yarn so that yarn can flow smoothly from the bundle to the knitting zone for fabric formation. The inner or operating surface of the guides ought to be smooth sufficient in order that neither yarn is damaged nor much tension is developed because to friction.
Feed plate or feeder is a small metal plate with a hollow at the center. Passing of yarn via the feed hole. The yarn passes through the hole earlier than being caught by the needle. The main causes of the use of the feed plate is to maintain a proper direction and alignment of the yarn in order that needles after getting cleared can catch the brand new yarn at tuck height level for loop formation without fail.
The number of such stop motions in a device is identical to the number of feeders .the presence of each feed yarn is for my part detected and motion is taken to stop the machine while the same is either broken or subjected to very high tension variation.
The needle is the main element in the knitting. The needle which actually makes the loop. three types of needle used in knitting (a) latch needle, (b) bearded needle and (c) compound or bi-partite needle.
Cam is the most important element in knitting. The cam is the mechanical device that converts the rotary device pressure into a suitable reciprocating movement for the needle. The needle moves through the cam. Two types of cam used in knitting 1.Engineering cam 2. Knitting cam.
Sinker is the second important element in knitting. It is a thin metal plate positioned in among the needles. The sinkers typically move to and fro in horizontal, at 90° to the path of motion of needles and maintain a fixed height. The sinker holds the needle while creating the loop.
Take down mechanism:
After the formation of every course, the cloth is withdrawn from the knitting zone, typically in a downward direction, and wound on the fabric roller. The mechanism used for this reason is a known take-down mechanism.
After knitting, the circular fabric in tubular form going downward for rolling into a roller as flattened double layered fabric. During such conversion, tension variation takes region across the width of the fabric because of distance variation version which ends up in unwanted, crease mark and stitch deformations To overcome this problem, knitting machines give with spreader or stretcher board for applying nearly uniform tension to the fabric. It is used to partly stretch the fabric same time as shrinking after coming down from the knitting zone.
Open width fabric winding:
Eliminate the fold mark in the fabric especially made with lycra and alike yarn and at the identical time to reduce the rate of alternate in diameter of the fabric roller to roll the equal period of fabric with a comparatively lower final diameter of the fabric roller.
Advantages of this system:
- Higher Productivity
- Excellent fabric quality with wider GSM range
- Easy Lycra plaiting and excellent Lycra plaiting quality – lower rejection
- Easy access to knitting head – higher efficiency
The value of the speed factor depends on the.
- Quality of yarn used
- construction of a knitting system
- Design of the fabric
- Environmental or climatic conditions
- Cleanliness of the machine
- Type of machine lubrication
