Abstract
Abstract A wire twisting machine including a base, a wire winding frame rotatably mounted on the base, a first wire containing spool mounted on the base, a guide arrangement on the frame for receiving wire as it is uncoiled from said first spool, a second wire containing spool, mounting means for mounting said second spool rotatably on said frame so that the second spool may be held stationary while said frame rotates and carries the wire from said first spool around the second spool so as to twist the two wires to form a strand at a location remote from the frame, and magnetic means for controlling the position of the second spool including a selsyn unit including a stator mounted on said base and a rotor mounted on the mounting means so as to cause said second spool to remain stationary or to selectively move so as to rotate the wire being uncoiled therefrom about its longitudinal axis to compensate for any twisting of the wire, with the wire guiding means comprising a tube which extends into the space between the rotor and stator so as to be able to rotate with the frame without engaging the stator. Alternatively, the magnetic means may comprise a magnet mounted in spaced relationship to the mounting means for attracting magnetic material on the mounting means to thereby maintain the mounting means stationary while the frame rotates. A sensing arrangement may be associated with the mounting means to detect whether it moves more than a predetermined amount. Instead of the magnetic means, the mounting means may be of such a configuration that it is acted on by gravity to keep it in a relatively stationary position as the frame rotates. If desired, the first spool can also have a magnetic arrangement such as a selsyn unit associated therewith to impart a predetermined rotation to the first spool to compensate for any twist which the wire emanating therefrom has around its longitudinal axis, or alternatively, a mechanical feed may be provided to the first spool to affect such rotation.
