DEFINITION

Classification: 242/520

CONVOLUTE WINDING OF MATERIAL:

(under the class definition) Apparatus or method for receiving elongated material from a supply and progressively coiling the material about an axis of a take-up to create successive convolutions so that at least the majority of convolutions lie upon their preceding convolution.
