The present invention is an epicycle dual drive apparatus comprising a frame supporting an input shaft, an output shaft and an epicycle drive coupling the input shaft and the output shaft. The apparatus has dual clutches means coupled individually to the input shaft and output shaft. The epicycle drive means includes an epicycle rack pivotally secured to said output shaft at one end and a crankshaft journaled for rotation at a second end. The output shaft may have a varying rate of rotation depending on the position of the center of the crank shaft on the epicycle rack with respect to the center of the input shaft. A Cam arrangement is used for coupling the input shaft and the crankshaft. The first clutch coupled to the output shaft allows for selective engagement of the output shaft and the second clutch is coupled to the crankshaft for selective engagement of the crankshaft. Only one clutch can be engaged at a time. Two timing pulley arrangements, each having a different pulley ratio, are selectively coupled by the two clutches to drive the output shaft and the crimper shafts coupled to it.
