摘要：PURPOSE:To smoothen driving of a mold by combining two spider-state pinions, which do not partially arrange teeth, to form one pinion and connecting each spider-state pinion with separate driving device as changeable in speed. CONSTITUTION:The spider-state pinions 16, which are partially no tooth at several positions to circular direction, are fixed at both ends of a driving shaft 15 and also the other pinions 22, which are partially no tooth at the same way, are fixed at both ends of a driving shaft 21 in a hollow driving shaft 15. Each of the pinions 16, 22 is arranged so as to form one pinion by mutually combining them at no tooth position. When gap G between racks 12 side by side caused by thermal expansion, etc., changes, rotating velocity of the pinion 22, which does not engage with the rack 12, is changed somewhat to low velocity and after passing for a short time, it is returned back to the original velocity. The pinion 22 is rotated as being delayed by pitch difference delta and the engaging points A, B are smoothly engaged. Therefore, the driving of the mold is smoothened.
