PURPOSE: To provide a packing sheet producing method capable of always producing a packing sheet utilizing a fiber other than asbestos in constant high quality and the control device of a packing sheet producing calender therefor. CONSTITUTION: The outputs of rotary counters 17, 19, temp. detectors 27, 31 of a heating medium and a cooling medium, a rotational speed detector and a sheet thickness measuring detector 22 are inputted to the computer 9 of the control device of a packing sheet producing calender. The control circuit of the computer 9 determines the numbers of rotations of the motors of a heating roll 2 and a pressure roll 3, the temp. of the heating medium and/or the cooling medium, a rotational speed, a solvent supply amt., inflection force, a material supply amt., a material distributing ratio, the rotational speed difference between both rolls and the pressing force of the pressure roll 3 on the basis of those outputs and controls respective devices related to a motor rotational speed regulator or the like. |
