Abstract

A method of longitudinally splitting a hollow tubular product comprising the steps of (a) providing longitudinal relative movement between the product and two blades of a cutter assembly arranged so that the blades partially cut through a portion of the wall of the product one from the inside and one from the outside to form two longitudinal slits in spaced planes with the inner ends of the slits adjacent to another and (b) applying a shearing force to the material in the region of the adjacent inner ends of the slits in a direction away from the planes of the slits to fracture the thickness of material between the inner ends of the slits to define a single stepped slit extending along the tubular product.
