Abstract
A method and device for slitting or edge trimming strip material on a process line are described in which trimming knives 2 mounted on a base 3 which is pivotally mounted on a sub-base 4, trim the edges of strip 14. The lateral position of the strip is sensed by sensors 10 and the position of the strip relative to center line of the process line is determined by a computer (not shown) which controls the lateral movement of the sub-base 4 by a hydraulic jack 9 so as to keep the strip and trimmer in alignment. The speed V of the strip is sensed and the speed V.sub.T of the trimmer is sensed by a transducer 12. The base 3 and thus each pair of knives 2 is pivoted about a pivot 11 on the sub-base 4 so that the angle .alpha. the knives make with the center line of the process, tends to equal tan .sup.31 1 (V.sub.T/V).
