Abstract
An electronic control system (9) controls the movement of a distributer (19) as the distributor guides strand (11) alternately onto reels (12 and 13). Digital signals are generated representing the instantaneous position of the distributor (19) and end-points of travel of the distributor. A controller (38) generates a signal when a coincidence of the instantaneous position of the distributor (19) and alternate ones of the end-points of travel of the distributor occur. The signal is used to reverse the direction of travel of the distributor (19) thus resulting in a uniform distribution of the strand (11) onto the reels (12 and 13). As each of the reels (12 and 13) become full, a signal is generated which causes the distributor (19) to proceed at a high rate of speed toward the back flange of the reel regardless of the direction of travel at that time. This facilitates the cutover of the strand (11) from a full reel to an empty reel.
