摘要 |
Upper and lower drums each with a blade are separated from each other by a hydraulic cylinder until a rotating velocity of the drums are accelerated to a predetermined level. Then, the drums are relatively approached by the cylinder so that gears each fitted to a shaft of the corresponding drum are engaged with each other to keep constant a gap between the blades. The blades are approached to a feed line of a strip to cut off the strip.
