What is a VDQ Pulley?
- VDQ stands for Variable Diameter Quality Pulley
- It's a component of circular knitting machines that regulates yarn tension and speed
- The pulley is designed with a variable diameter that changes as the yarn passes through it
- The size of the pulley can be adjusted to control the tension and speed of the yarn

Function of the VDQ Pulley:
- Regulates the tension of the yarn as it passes through the machine
- Prevents yarn breakage and ensures consistent quality of the fabric
- Controls the speed of the yarn, which affects the overall appearance of the fabric
- Works in conjunction with other components of the machine, such as feed rollers, needles, and sinkers, to produce high-quality fabrics
- Its proper functioning is essential for producing fabrics with consistent properties
We can say the Main function of VDQ Pulley is-
- Control yarn supply
- Control yarn tension
- Control stitch length
- Finally control G.S.M
Changing of stitch length by VDQ pulley (How VDQ Pulley works) :
The VDQ pulley in a circular knitting machine is designed with a variable diameter that changes as the yarn passes through it. This allows it to regulate the tension of the yarn and control its speed. As the yarn passes through the pulley, the size of the pulley adjusts to maintain consistent tension and prevent yarn breakage.
How VDQ Pulley works
The operator can adjust the size of the pulley to control the tension and speed of the yarn, which affects the properties and appearance of the fabric being produced.
There is a nut or screw under or over the pulley. After losing the nut we can change the diameter controlling parts. If we rotate ‘+’ direction diameter will increase and stitch length will increase. If we rotate ‘-‘ direction diameter will decrease and stitch length will decrease.
Overall, the VDQ pulley is a critical component of the circular knitting machine and plays a vital role in producing high-quality fabrics with consistent properties.
Advantages of VDQ Pulley:
- Provides better control over yarn tension, resulting in fewer defects in the fabric
- Helps to prevent yarn breakage, which can cause downtime and loss of productivity
- Enables the production of fabrics with consistent quality and properties
- Allows for greater flexibility in fabric design and production
