ABSTRACT:
A clutch arrangement for a multi-spindle machine includes a starting clutch 12 and a machine brake clutch 14 positioned on a starting clutch drive shaft 16. A high speed clutch 18 and a snubbing clutch 22 are positioned on a long worm drive shaft 20. All clutches are pneumatically operated by solenoid valves 40, 42, 44 and 46 and electrically actuated by electrical circuit 60. When the multi-spindle machine shifts from a high speed to a low speed, the present invention activates the machine brake clutch 14 and snubbing clutch 22 for a predetermined time period to cause the drive train gears to slow down allowing synchronous meshing with the low speed drive train of the multi-spindle machine to enable a reduction in machine cycle time.
