ABSTRACT:
An apparatus for perforating corrugated tubing is disclosed. The apparatus receives tubing to be perforated along an axial path coincident with the axis of the tubing. A plurality of feeder-cutter wheels drive the tubing through the apparatus and concurrently perforate the tubing in the valley of its corrugations. Each feeder-cutter wheel, and the drive shaft each wheel is mounted upon, is offset at an angle relative to the axial path, this angling facilitating uniform perforations at higher speeds. An alternate embodiment of the apparatus has six feeder-cutter wheels disposed within four distinct planes. This design permits the wheels to be interchangeable with different wheels, allowing the apparatus to perforate tubing of different diameters. The alternate embodiment also offsets the wheels at an angle to facilitate perforation at high speeds than previously known in perforating apparatus.
