DEFINITION

Classification: 242/360

LOOP FORMING (E.G., WINDING A BUNDLE OF WIRE COILS):

(under the class definition) Apparatus or method for either, (a) progressively winding an elongated material into convolutions (loops) to provide a coreless storage package tending to maintain its shape as a consequence of winding, or (b) ancillary means intimately associated with such winding apparatus for transferring successive convolutions (loops) or convolution groups (bundles) from the winding apparatus.

(1) Note. Apparatus or method for specifically bending material beyond its elastic limit is excluded from this class.

(2) Note. To be placed in this or indented subclasses the winding device must be of the type in which the loops of material are transferred individually or in unbound groups from one support to another with no substantial change in their looped shape. e.g., the loops may be formed by winding upon a cylindrical form rotating about a vertical axis and subsequently fall axially over the lower end of the form onto and over a stationary core or into a container, the shape of the loops remaining substantially unchanged during this transfer process. Apparatus and methods for making coreless wound packages, packages of coils supported internally to maintain their shape, or packages that undergo substantial changes in shape after formation are provided for elsewhere. See the search notes below.
