International ClassB26F 003/00AbstractA 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.Field of SearchCutting by direct application of fluent pressure to workBy fluid application By suction means BY FLUID BLAST AND/OR SUCTION Orbital motion of cutting blade With means to move tool laterally of feed direction during cutting Interrelated work-conveying and tool-moving means Interrelated work-feeding means and tool-moving means NOTCHING During movement of work past flying cutter Tool carrier oscillated or rotated Notching of work edge | |
