DEFINITION

Classification: 242/470

HELICAL OR RANDOM WINDING OF MATERIAL:

(under the class definition) Apparatus or method for creating a storage coil formed by coiling an elongated material (e.g., textile strand, wire, or narrow web) directly on the outer surface of a take-up member adapted to be supported at a winding station while either systematically distributing convolutions of the material parallel to the axis or permitting convolutions of the coiled material to be placed at indiscriminate points along the axis in which the coiled material is removed from the winding station (i.e., removed from the means for supporting it for rotation) before unwinding the material.

(1) Note. This subclass includes winding or unwinding a relatively small portion of the material on or from the storage coil or a spool for the purpose of facilitating future or continued winding or unwinding of the material (e.g., for repositioning the outside end of the material).

(2) Note. The combination of a traverse guide for controlling the distribution of material on a rotating take-up with means for moving the guide is a subcombination of a helical winding apparatus that is properly classified here even if a take-up member is not present. A guide without structure designed to move it in a manner to control distribution of material on a take-up is classified in the appropriate guide subclass elsewhere in this class even if it is intended to be used in a traverse mechanism.
