A mechanism for changing the direction of travel of a continuous and rapidly moving bendable rod through a substantial angle in the order of 90 DEG . The mechanism consists of a power driven grooved guide wheel and a plurality of rotating closely adjacent smaller guide wheels located along a segment of the periphery of the main guide wheel about which the rod is to be turned. Some of the smaller guide wheels are slanted alternately with respect to the main guide wheel. The slanted wheels overlap each other so that over a given angular segment of the main guide wheel, there may be more positions of engagement of the smaller guide wheels with the rod thereby to maintain full control of the rod as its line of travel is changed and to insure complete delivery of the rod for its entire length to a rod collecting device. |
