Method of controlling web cutting |
摘要 |
A method for controlling the speed of a rotary cutter to cut a continuously fed web accurately into predetermined lengths. A desired cutting length and the circumference of the rotary cutter are preset. The web speed as detected is multiplied by a coefficient equal to the cutter circumference divided by the cutting length. The resultant signal is compared with the cutter speed as detected, and, if there is any difference, the cutter speed is corrected for accurate cutting.
