Abstract
Pre-twisted multiple wires having N twisted sections per full-twist pitch, where N is a predetermined constant integer, are juxtaposed to a roller which carries plural conformal seat means in a circumferential manner. The arcuate spacing between adjacent seat means is correlated with 1/Nth of the full-twist pitch of the particular twisted wires. Associated with the roller is ratchet means which allows the roller to be indexable in increments correlated with a full-twist pitch of the particular multiple twisted wires. As a result, the twisted wires are fed out in full-twist linear increments and, hence, with the same orientation of the wires for each incrementing step. Moreover, by judiciously seating one of the N possible adjacent twist sections of the twisted wires with respect to the seat means, the twisted wires can be fed out selectively with N possible orientations. The preferred embodiments described herein orient a pair of twisted wires which have two twisted sections per full-twist pitch, that is to say, two half-twist sections per full-twist.
