Abstract
PURPOSE: To prevent any slippage between a material and a roll by adding a memory.
CONSTITUTION: There are additionally provided a memory 31, which is operative partly to sample the non-load current of a measuring roll 14 while this roll 14 is moving down and partly to store the value of the current immediately before the rise start, a timing detector 33 and a reference presetter 32. As a reslt, the output of the memory 31, which is stored in accordance with the command of the detector 33, is fed to the presetter 32, and the difference of the roll current upon contact from that output is fed to a roll contact current controlling amplifier 23 so that the output of this amplifier 23 is impressed as a speed compensating input upon a speed controlling amplifier 24. As a result, even if the non-load current of a motor 15 for driving the roll 14 is varied in accordance with the conditions of a bearing or grease, it is detected for each material 13 and is used to adjust the roll current after contact with the material 13 thereby to eliminate any slippage between the roll 14 and the material 13 while they are rotating in contact.
