PURPOSE:To provide a control system of a line for coating glass fiber for controlling the looseness of a material generated between a coating section and a drying section constantly and generating no creases. CONSTITUTION:Conveyors 11, 12 and the like before a coating section A are driven by a first motor M1 through a first half line shaft S1, while conveyors l3-l5 and the like after a drying section B are driven by a second motor M2 through a second half line shaft S1. The speed of the first motor is controlled by a first inverter INV1, while the speed of the second motor is controlled by a second inverter which controls the speed by a speed signal e1 of a speed sensor PG for sensing the speed of the conveyor l2 of the coating section A. The speed instruction of the inverter is corrected by a sensing signal e2 of a looseness sensor for sensing the change of looseness (a) of a material W, and the looseness (a) generated between the coating section A and the drying section B is controlled constantly. |
