Abstract
A double twist machine uses a reel on which two or more wires have been wound. Guides are provided within the double twist machine for simultaneously guiding all of the wires and imparting two twists to the entire set as the wires proceed through the double twist machine to thereby produce a set of wires twisted about each other which are all simultaneously taken off a single bobbin or reel. The number of wires on each reel and the number of bobbins mounted within the machine may be varied to produce telephone cable twins, triplets, quads and the like. A take-up used in conjunction with a bank of such machines can produce a wide variety of telephone cables.
Claims17
Apparatus for making telephone cables with multi-wire reels, comprising a frame;
- rotating means arranged in a substantially balanced configuration for rotation about a first axis relative to said frame, said rotating means including at least one elongate member in the form of a bow offset from said axis which defines an envelope as said bow rotates about said axis;
- a cradle mounted for rotation about said first axis and dimensioned and configured to be contained within said envelope and adapted to receive as few as a single reel for rotation about a second axis substantially normal to said first axis mounted within said cradle and at least one reel of which is wound with a set of at least two wires which is simultaneously unwound from said as few as a single reel;
- cradle fixing means for maintaining the position of said cradle substantially fixed about said first axis relative to said frame during rotation of said rotating means;
- guide means for simultaneously guiding the set of at least two wires from said at least one reel on said stationary cradle to said rotating means and thereafter to said stationary frame thereby imparting at least one twist to the set of at least two wires unwound from the reel and a tension control device within said envelope for each said at least one reel to maintain the tension in all the wires in said set of at least two wires at a substantially constant predetermined value.

- guide means for simultaneously guiding the set of at least two wires from said at least one reel on said stationary cradle to said rotating means and thereafter to said stationary frame;
- and single tension control means for each said at least one reel to maintain the tension in all the wires in said set of at least two wires at a substantially constant predetermined value, thereby imparting a twist to a set of at least two wires unwound from said as few as a single reel.
Method of making telephone cables with multi-wire reels, comprising the steps of rotating at least one elongate member in the form of a bow offset from a first axis for defining an envelope as said bow rotates about said first axis;
- mounting a cradle for rotation about said first axis within said envelope and receiving as few as a single reel within said cradle for rotation about a second axis substantially normal to said first axis;
- simultaneously unwinding from said as few as a single reel a set of at least two wires;
- fixing said cradle for maintaining the position of said cradle substantially fixed about said first axis relative to a frame during rotation;
- simultaneously guiding the set of at least two wires from said at least one reel on the stationary cradle to said bow and thereafter to said frame thereby imparting at least one twist to the set of at least two wires unwound from the reel;
- and maintaining the tension in all the wires in said set of at least two wires at a substantially constant predetermined value.
