PURPOSE:To correctly control tension by feedback-controlling the frictional driving torque of each taken-up sheet according to the taking-up tension pattern obtained by setting the frictional driving torque between the taking-up driving shaft and a number of core-pipe receiving rings fitted onto the taking-up driving shaft. CONSTITUTION:A number of core-pipe receiving rings 2 are fitted onto a taking- up driving shaft 1 revolved by the drive of a driving motor, and a sheet roll R is formed onto said ring 2. The core-pipe receiving ring 2 receives the turning moment of the driving shaft 1 through a frictional transmission mechanism (not shown in the figure), which is controlled by a frictional adjusting apparatus. Said frictional adjusting apparatus controls the taking-up torque so as to become suitable for a set tension according to the detected value of the taking-up amount by a computer having a taking-up tension or taking-up torque-taking-up amount relation setting part. The above-described frictional adjusting apparatus is feedback-controlled according to the output of a torque detecting apparatus installed into the power transmission passage between the driving motor and the driving shaft 1.
