ABSTRACT:
Apparatus and process for fabricating flexible belts in which the apparatus comprises at least one cylindrical mandrel having a plurality of moveable segments arranged around the periphery of the mandrel, each of the segments having an outwardly facing gripping surface which cooperates with adjacent gripping surfaces on adjacent segments to form a substantially cylindrical surface having at least one annular groove which circumscribes the substantially cylindrical surface. The segments are movable radially away from the axis of the mandrel to grip a flexible tube. Upon rotation of the mandrel, at least one cutting means adjacent to and spaced from the groove and the cylindrical surface of the segments are moved relative to each other whereby the cutting means circumscribes the mandrel along a path defined by the groove to cut the tube into belts.
