Set-up Main Parts of a Circular Knitting Machine:

Creel: Creel is a vertical aluminum stick where creel is placed for holding the yarn cone. It also known as side creel.

Cone Holder: Cone holder is an inclined metallic stick where yarn cone is placed for feeding the yarn to the feeder easily. It is also known as cone carrier.

Aluminum Telescopic Tube: This is the tube through which yarn is passed. It works as a yarn cover. It protects the yarn from the excessive friction, dust and fly fiber.

MPF Device: MPF means Memminger Positive Feed. It receives yarn from aluminum telescopic tube. As this device gives a positive feed of yarn to the needles, so it is called Memminger Positive Feed device.

Winding Wheel & Driven Pulley: Some yarn is rolled on the winding wheel so that if the yarn is torn off, the whole yarn does not need to be replaced again.

Yarn Tensioner: Yarn tensioner is a device that ensures the appropriate gripping of yarn.

Stopper: Stopper is a part of MPF. If yarn breaks, then stopper gets upwards and the sensor receives a signal to stop the machine.

Sensor: The sensor is located at MPF. If anyone of the stoppers gets upwards due to the breakage of yarn, the sensor automatically receives signal and stops the machine.

Lycra Attachment Device: Lycra yarn is feed by the following device.

Yarn Guide: Yarn guide receive yarn from the MPF. It is used to guide the yarn and sent yarn to the feeder guide. It maintains the smooth tension on the yarn.

Feeder Guide: Feeder guide receive yarn from yarn guide and feed yarn to the needle. It is the last device which releases yarn to the knit fabric.

Feeder Ring: This is a circular ring which holds all the feeder guide.

Needle: Needle is the master part of the knitting machine. Needle receive yarn from the feeder, create a loop as well as release old loop and finally produce the fabric.

VDQ Pulley: VDQ means Variable Dia for Quality. As this pulley controls the quality of knitted fabric by adjusting GSM & stitch length during the knitting process.

Pulley Belt: Pulley belt gives the motion to pulley

Cam: Cam is the device which converts the rotary motion into a definite reciprocating motion for the needles and some other devices.

Cam Box: Cam box holds and supports cam. Knit, truck and miss cam are arranged horizontally according to fabric design in the cam box.

Sinker: Sinker is another master part of the knitting machine. It supports yarn to form the desired loop. Sinker is located at each and every gap of the needle.

Sinker Box: Sinker box holds and supports the sinker.

Sinker Ring: This is a circular ring which holds all sinker box

Cylinder: Cylinder is another master part of the knitting machine. The cylinder holds and carries needle, cam box, sinker, etc.

Body: The body of the knitting machine covers the whole area of the machine. It holds base plate, cylinder, etc.

Base Plate: Base plate is a plate that holds the cylinder. It located on the machine body.

Air Blow Gun: A device connected with high-velocity pressurized air. It blows air to feed the yarn through the aluminum tube.

Automatic Needle Detector: A device placed very close to the needle sets. It gives a signal if it found any broken o damaged needle.

Fabric Detector: If fabric torn off or fall down from the machine, fabric detector touch the cylinder and the machine becomes stopped.

Adjustable Fan: Generally two sets of running fans are continuously circulated from the center of machine dia.

Lubricating Tube: This tube supplies lubricants to the cam box, sincar box to remove excessive friction and heat.

Manual Jig: It is attached with the machine body. It used to adjust needle, sinker, etc. manually.

Gate: Gate is situated under the machine bed. It keeps covered the knitted fabric, take-down motion rollers, and winding rollers.

Spreader: Spreader is situated below the machine body. It receives fabric from the needle, spreads fabric and ensures uniform fabric tension.

Take-Down Motion Rollers: TThey pull fabric from the spreader, grip fabric firmly and take fabric down.

Winding Roller: This roller is situated just under the take-down motion rollers. It rolled the fabric itself. When this roller becomes bigger by the fabric layer it also moves upward.
