Winding Machine
There is only one winding machine ,which is used only optionally i.e. when the package supplied from the spinning machine are in a deform shape , improperly wound or when there is more than 150 m of yarn left in the package used for ball warping . These packages are taken for rewinding and cones are made on this machine.
The different characteristics and parameters of this winding machine are:
- Maker —–Auto industries , Ahmedabad
- Type ——grooved drum winding machine
- of winding heads—–60
- Winding speed——-300
- Drum diameter——-4
- of crossing per double traverse——-5
- Package conicity—–5o57’
- Winding angle——-340
The path of the yarn is shown in figure .An patterning device is attached with the driving arrangement, which works on the principle of intermittent disengagement of the drive from the motor.

QUALITY ASSURANCE
This department takes care of the quality aspect of the raw materials (fibre and yarn) and other auxiliaries for processing of the material, either produce from outside or that being produced over here ( at different stages of the processing) . it also looks after the various processing parameters and the extent of utilization of resources. It comprises of two departments, one the physical testing lab and the other is chemical testing lab.
