Abstract

PURPOSE:To easily and highly accurately change the peripheral speed of the roll of a stretching machine in a short time by a method wherein the rotation on the output side of a stepless transmission provided in a driving system for stepless speed change is given to the center shaft of a cam in a differential gear mechanism. CONSTITUTION:A power transmission gear 22 and a pulley 23 are attached on a roll, which acts as a peripheral speed reference. The gear 22 is connected to an idle gear 24, the spline S of a differential gear mechanism 25, a gear 26 fixed onto the spline S, a spline 27, the pitch of which is the same as that of said spline S and the number of teeth of which is different from that of said spline S, a spline D, the pitch and number of teeth of which are respectively the same as those of said spline S, a gear 26A and a gear 28. The pulley 23 is connected through timing belts 32 and 38 to the output shaft 33 of a stepless transmission 29 and to the center shaft 35 of a cam 34 in the differential gear mechanism 25. Because the rotation on the output side of the stepless transmission 29 is transmitted under the condition that the speed of the rotation is changed to the center shaft 35 in a driving system for power transmission, the speed of the spline D is changed, resulting in changing the speed of a roll 15 continuously.
