DEFINITION

Classification: 156/425

(under subclass 349) Apparatus which includes means to progressively bend or wrap an indefinite running length work around a base in such a manner that convolutions are formed with each convolution axially displaced along the base from the preceding convolution.

(1) Note. For the purpose of this subclass the base may be any structure upon which the material is wound regardless of its shape and whether it is later removed or becomes part of the article. The actual length of the material being wound is immaterial so long as it is handled as an indefinite or running length work.
