550 operates in a manner such that the cylinder 560 may raise or lower the wheel 564 from the belt 512 the course adjustment aligner 548 has a forward sensor 568 located forwardly of the wheel 556 over the belt 512 and spaced a substantial distance from a plate or edge 570 against which it is desirable to align the sleeve the course adjustment aligner 548 also has a rear sensor 572 located rearwardly of the wheel 556 and in close proximity to the edge against which the sleeve is to be aligned as the sleeve passes along the belt 512 both the sensors 568 and 572 are verified by the central processing unit to determine the presence of the sleeve beneath the respective sensors 568 and 572 in the event that the sensor 568 indicates presence of the sleeve while the sensor 572 indicates that the sleeve is not beneath the sensor 572 the cylinder 552 raises and lowers the wheel 556 and causes pulsating movement of the sleeve toward the edge 570 to the desired aligned position however once the sensor 572 indicates presence of the sleeve beneath the sensor 572 the central processing unit causes actuation of the cylinder 552 to lift the wheel 556 and prevents further movement of the sleeve toward the edge 570 since the sleeve is substantially aligned with the edge 570 by the course adjustment aligner 548 after this operation by the course adjustment aligner 548 the sleeve passes toward the fine adjustment aligner 550 for.
