Ring Spinning Tubes

Distinctive Features of Veejay Ring Tubes:

  • Immaculate surface finish with microgrooves and perfect overgrooves.
  • Superior performance even at 25000 rpm.
  • Fitting dimensions and wall thickness exactly as per Machinery manufacturer specifications, which in turn increases, not only the life to the tube, but also the life of the spindle.
  • Made from Polycarbonate and ABS.
  • Excellent Dimensional Stability.
  • Negligible eccentricity values and high concentricity values in conformance to International standards resulting in constant yarn tension and less yarn breakages.
  • Suitable for manual and auto doffing.
  • True running for a longer period and hence leads to lesser energy consumption.
  • Product range consists of ring tubes for all types of spindles and various taper ratios like 1:40, 1:38 and 1:64
  • Wide array of colours to choose from, apart from the facility of customization of colour according to the customer's imagination.
Ring Spinning Tubes

The following literature assists in choosing the ideal ring tube

Overall Length: The total length of the ring tube is known as the overall length. The overall length of the tube depends on the spindle length and ideally the difference between the overall length of the tube and the spindle length should not be more than 20 mm.

Lift of the tube: The distance for which yarn could be wound on the tube is called the lift of the tube.

Tube Overhang (Tube Clearance): The clearance between the top of the ring tube and the top of the spindle is called as tube overhang or tube clearance. Ideally, it should be kept as low as possible, and it should not be more than 20 mm, so that there are no breakages at higher speeds.

DUI / DOI: The bore diameter of the tube required to fit on the bottom of the spindle is known as Diameter Under Insertion (DUI), and the bore diameter required to fit on the top of the spindle is known as Diameter Over Insertion (DOI).

Taper Ratio: Taper ratio is a measure of the rate at which the diameter of the tube decreases in terms of the length of the tube. For example, if the taper ratio is 1:40, there will be decrease of 1 mm in the tube diameter for every 40 mm length of the tube. The various taper ratios available are 1:38, 1:40 and 1:64

Wall Thickness: Wall thickness is nothing but the thickness of the tube. It is always better to stick to the machinery manufacturer's specification on wall thickness, so that the machine could be run at high speeds, and the ring tubes will also have good lifetime. The weight of the tube is directly proportional to its wall thickness. Our ring tubes will have uniform wall thickness from bottom to top.

Eccentricity: The eccentricity is the measure of variation in the circularity of the ring tube, and is measured by the variation in the radius of the tube, when in rotation. The lower the eccentricity of the tube, the better will be the results. Our ring tubes will have eccentricity far less than the machinery manufacturer's specification.

Pressing Force: Ideally, the ring tube should press on the spindle with a pressure of 0.75 - 1.50 Kg, which would ensure better life for both the spindle and the tube. Precise dimensions, proper taper, and smooth internal surface are key factors for achieving this. Our ring tubes are so designed as to have an ideal pressing force
