WINDING OF CONICAL PACKAGES AT CONSTANT DELIVERY RATE - PART II - A NEW TENSION COMPENSATORY SYSTEM FOR USE IN FIXED RATE DELIVERY

The quality of a conical yarn package depends on the winding tension o f the yarn wound onto the package. The problems of tension variation c ontrol during cone winding are different from those in cheese winding. In cone winding the peripheral speed of the package is varying and th is results in the yarn tension changing during package building. This effect can be eliminated by storing and releasing a quantity of yam by means of a compensatory system. An analysis of the problem and the re sult of reducing variations in winding tensions are described.
