Process control in ring spinning frame:

The ring spinning frame has the following variable spaces to control the spinning process:

1. Draft change pinion or D.C.P.

2. Twist change pinion or T.C. P.

3. Winding length change pinion or W.C.P.

4. Break draft change pinion

5. Spindle speed change puli

1. Draft change pinion or D.C.P.:

It is possible to change the draft through the draft change pinion. If you increase the draft pinion, the draft will decrease and if you decrease it, the draft will increase. The yarn produced thick due to the large pinion. https://bdfabric.com/what-is-the-yarn-twist-definition-objects/

2. Process control in ring spinning frame-Twist change pinion or T.C. P.:

This pinion changes the speed of the front roller. T.C.P. when it is big, delivery is more and twist is less. https://bdfabric.com/roller-clearer-of-ring-spinning-machine/

3. Process control in ring spinning frame-Winding length change pinion or W.C.P.:

The winding length change increases and decreases the speed of the pinion cam. Enlarging the pinion increases the speed of the builder cam and causes the ring rail to move too fast and the winding density decreases and the winding length of the bobbin decrease very quickly.

4. Break draft change pinion:

Break Draft Change Pinion controls the speed of the middle roller. If the change pinion is enlarged, the speed of the middle roller will be reduced and the break draft will be less and if the pinion is short, the break draft will be more.

5. Spindle speed change puli:

The spindle speed is controlled by the puli, the larger wheel increases the speed of the spindle.

Apart from the aforementioned variable wheels, the Draft Constant Change Pinion and Twist Constant Change Pinion were changed to Constant Change. In addition to the various variable wheels, there are two methods for changing the speed of the spindle. i.e.

(A) Variable puli

(B) Inverter drive fixed speed drive

(A) Variable puli:

It is possible to change the speed of the spindle of the ring frame by the variable puli. In this method, there are two dicks on either side, so the speed of the spindle is changed by the movement of the dicks by removing the belt by applying pressure.

(B) Inverter drive fixed speed drive:

The inverter drive is driven by a fixed-speed drive only at a certain speed. The speed of the spindle is changed by changing the speed of the motor through the inverter, a controller.
