Crochet Warp Knitting Machine

Experiment name: Study on Crochet Warp knitting machine.

Objectives:

• To get clear concept about the driving mechanism of crotchet knitting machine.
• To know the functions of different parts of the machine.
• To know about the different motions of the machine.
• To know different parts of the machine.
• To improve our technical knowledge.

Specification of the machine:

1. Company: DAH HEER Industrial Co. LTD.
2. Brand: DAHU.
3. Origin: Taiwan.
4. Model No: L
5. Size: 15 G

Main parts: 

1.  Motor 
2.  Main shaft 
3.  Size lever 
4.  Shogging motion lever 
5.  Weft yarn guide bar 
6.  Warp yarn guide bar 
7.  Needle bar 
8.  Needle 
9.  Pressure roller 
10. Take up roller  
11. Ratchet wheel

Machine description:
The machine is driven by an electric motor. Motion is transferred to the machine parts by gear and toothed belt. Here weft yarn guide bar gives to and fro motion and shogging motion. Shogging motion lever give motion to the weft yarn guide bar. Shogging motion is driven from motor by main shaft. Needle bar and warp yarn guide bar also give to and fro and shogging motion by the same mechanism.Take up roller has ratchet wheel, by which take up roller gets motion from the motor by pushing pawl amd some mechanism.

Conclusion:
First of all I would like to offer my heartily thanks to our supervising tutor and the lab assistants for their consistent help to complete the study properly. Crotchet knitting machine is one of the most important knitting machines to produce knitted fabric.
