This document discusses the parts and functions of a circular knitting machine. It outlines 23 main parts of the machine including the creel, pulley belt, tension disk, inlet and outlet stop motion, yarn guide, MPF wheel, MPF, feeder ring, disk drum, pattern wheel, feeder, needle track, needle, sinker, sinker ring, cam box, cam, Lycra attachment device, Lycra stop motion, cylinder, cylinder balancer, and air gun nozzle. It provides a brief description of the purpose and function of several key parts like the creel, VDQ pulley, tension disk, MPF, feeder, needle, and sinker. The objective is to understand how

6. 1.Creel: Creel is a part of a knitting machine. Hear yarn package are store and ready to
feed in the machine.
2. Pulley Belt: It controls the rotation of the MPF wheel.
6

7. VDQ Pulley: It is a very important part of the machine. It controls the quality of the
product. Altering the position of the tension pulley changes the G.S.M. of the fabric. If
pulley moves towards the positive directive then the G.S.M. is decrease. And in the reverse
direction G.S.M will increase.
Brush: Its clean the pulley belt.
7

8. Tension Disk: It confronts the tension of the supply yarn.
Inlet and Outlet Stop Motion: It is an important part of the machine. It stops the machine
instantly when a yarn is break.
8

9. Yarn Guide: Its help the yarn to feed in the feeder.
MPF Wheel: Its control the speed of the MPF. Pulley belt gives motion to the wheel.
9

10. MPF: It is Mamenger positive feed. It is also an important part of the machine. It’s give
positive feed to the machine.
Feeder Ring: It is a ring. Where all feeders are pleased together.
10

11. Disk Drum: Use in jacquard machine to produce various types of design.
Pattern Wheel: Pattern Wheel use in Pai Lung and Auto Stripe machine because of that
that help to produce various types of design and stripe.
11

12. Feeder: Feeder is help yarn to feed in to the machine.
Needle Track: Where all Needles is placed together in a decent design.
12

13. Needle: It is a principal element of the knitting machine. Its help the yarn to create a loop.
And by this way fabric are produce. Prior to yarn feeding the needle is raised to clear the
old loop from the hook, and received the new loop above it on needle stem. The new loop
is then enclosed in the needle hook as the needle starts to descend.
Sinker: It is most important element of the machine. Its help to loop forming, knocking
over and holding down the loop.
13

14. Sinker Ring: Sinker ring is a ring. Where all sinkers are pleased together.
Cam Box: Where the cam are set horizontally.
14

15. Cam: Cam is device s which converts the rotary machine drive in to a suitable
reciprocating action for the needles and other elements.
Lycra Attachment Device: Lycra is placed hear. And feeding to the machine.
15

16. Lycra Stop Motion: It is one kind of stop motion to stop the machine when the Lycra is
break.
Cylinder: Needle track are situated hear.
16

17. Cylinder Balancer: It helps the cylinder to set in a proper alignment.
Air Gun Nozzle: To feed the yarn; sometimes it is used for cleaning purpose.
17

18. Adjustable Fan: This part removes lint, hairy fiber from yarn and others. To clean the
dust by air flow.
Needle Detector: This part detect the any type of faults of needles.

19. Conclusion
This experiment has significance in our study life.In this experiment we know
different problem & related maintenance of circular knitting machine.we point
out the various specification of the machine.
