PURPOSE:To wind a multi-strip piece of high quality by controlling balance of three energies-i.e., feed energy to the multi-strip piece given by a loop control roller, the winding kinetic energy for the multi-strip piece, and the own energy of the multi-strip piece-by the use of rotational speed of the loop control roller. CONSTITUTION:A steel sheet 10 is wound back from coil by a rewinder 11 and cut into a multi-strip piece by a slitter 12. This is induced by control rollers 1-3 constituting a loop control roller and wound by a winding machine 16 after passing a separator roller 4 at the outlet from a loop forming trough 13. Velocity factors for each control roller 1-3 are determined from the weight of material to be processed itself and the frictional coefficient of it with the rollers. When this forms a loop r1 between roller 3 and separator roller 4, a signal from sensor 14 is fed into a rotational speed controller of roller 2 so as to form a loop r2 between the rollers 2 and 3, and in the same manner a loop r3 is formed between the rollers 2 and 1 through the sensor 14, and this process should be repeated.
