Abstract
A process and apparatus for making a repetitive arc cut in a continuous manner in a continuous supply of sheeting possessing edges, which involves providing a moving sheeting across a cutting area and passing through the area an arc-directed omnidirectional cutting means at and across an edge, in the general direction of the sheeting, to puncture a portion of the moving sheeting, maintaining the arc directed velocity of the omnidirectional cutting device at a rate greater than that of the directional velocity of the sheeting such that the puncture is enlarged to a lineal cut. The most favorable application of the invention involves the use of waterjet cutting to cut holes, especially primarily round holes, in multi-wall plastic constructions.
