Apparatus and process for fabricating flexible endless belts from a tube (82) comprises at least one cylindrical mandrel (22) having a plurality of movable segments (62) arranged around the periphery of the mandrel, each of the segments having an outwardly-facing gripping surface (63) which cooperates with similar surfaces on adjacent segments to form a substantially-cylindrical surface having at least one annular groove. The segments are movable radially away from the axis of the mandrel to grip an outer flexible tube. Upon rotation of the mandrel, at least one cutter (48) adjacent to, and spaced from, the groove and the cylindrical surface of the segments is moved relatively to the mandrel whereby the cutter incises the tube along a path aligned with the groove, to cut the tube into belts. |
