Abstract

PURPOSE:To hold the acceleration and tension of a tape constant, by controlling a torque of a reel motor at the acceleration and deceleration of the tape. CONSTITUTION:Tape winding diameters rS and rT or each reel of supply and widning are respectively detected at 1S, 1T, and supplied to circuits 10S, 10T obtaining torques MTS and MTT given to the reel motor. A monent of inertia of the reels is detected at a circuit 20. In this case, tape tensions FS and FT of each reel and the acceleration alpha are detected, they are compared with a set value and counted and given to the circuits 10S and 10T as the moment of insertia ISR and ITR of each reel to be correctable. Each output of the circuits 10 controls the torque of each motor. Each detection value of the FS and FT as the result of torque control is compared again and the moment of inertias ISR and ITR are corrected and the acceleration alpha and the tensions FS and FT are converged into each set value.
