Abstract: An apparatus for flaring plastic tubing comprising a motor and speed reducing unit mounted on a slide member for relative movement towards and away from a set of stationary die members in which various diameters of plastic tubing may be inserted. A flaring head is mounted on the output shaft of the speed reducing unit in alignment with the central axis of a tubing positioned in the dies. The maximum forward and rearward movement of the slide member is adjustable so that the necessary movement for producing the desired flare on various diameters of tubing can be produced.

Abstract: Polybutylene tubing is flared by a method and apparatus wherein the tubing is clamped at a position spaced from the end to be flared, and the projecting end portion is progressively engaged by a rotating flaring member having a working face of special segmental configuration such that as it advances into the tubing, an undulating circulatory pattern is developed in the tubing material accompanied by expansion thereof into the desired flare.
