DEFINITION

Classification: 57/58.3

(under subclass 1) Means for twining or twisting together two or more strands, in which strands from a plurality of sources of supply extend to a closing point with the strand from at

least one such source being revolved (as by a flyer) about at least one other such supply source before being intertwisted or intertwined with the remaining strand or strands.

(1) Note. In a typical structure of this type, most of the strand supply sources are mounted substantially co-axially within an elongated cradle, tube, cage, or flyer, and the strands are led to points away from the axis of such structure (to clear other supply sources) and thence along the structure toward a closing point which is beyond the confines of the flyer but located on the axis thereof. The revolution, about the remaining packages, of the strand(s) to be twisted is like the revolution of the rope about the jumper in rope skipping.

(2) Note. The component strands are laid together in adjacent helical convolutions, with or without twisting of the individual strands forming such convolutions. Such individual component twisting depends upon the revolution of the individual supply source, from which the component strand emanates, about an axis substantially parallel to that of the unwinding strand.

(3) Note. The devices of this subclass are distinguished from those of subclass 58.49 in that here a strand does not necessarily pass in a loop about its own supply. Multiple twisters, however, may be found as subcombinations of the apparatus of this and indented subclasses.
