Abstract: The present invention provides a method and apparatus for the rapid, uniform curing of cylindrical, polymeric objects. The invention provides precise, accurate control of both the curing temperature and pressure because the heating system is independent of the pressurization device. Cylindrical polymeric objects are cured by mounting the object on a cylindrical mandrel, applying substantially uniform pressure to the outer surface of the object, typically through an expandable bladder, and supplying curing is heat directly to the object by circulating a liquid heat transfer medium through the bladder or mandrel. Preferably, the expandable elastomeric bladder is mounted coaxially with the mandrel, and is expanded with a suitable liquid or gas to provide the pressure. The liquid heat transfer medium can be pumped through a passage in the mandrel to apply heat directly to the interior of the object, or the liquid heat transfer medium may be used to expand the bladder and apply the curing heat to the exterior of the object. Alternatively, a combination of both techniques may be employed.

Abstract: A vulcanizing apparatus including a cylindrical vulcanizing drum for winding and molding unvulcanized rubber belt materials thereover, the vulcanizing drum being removably and rotatably supported on a transfer mechanism. A pair of endless pressurizing bands are arranged to oppose each other with the vulcanizing drum between, the pressurizing bands arcuately surrounding and pressing the corresponding portions of the circumferential surface of the vulcanizing drum. While the circumferential surface of the vulcanizing drum is heated inside, and the respective pressurizing bands are opposingly pressed against the vulcanizing drum, the respective pressurizing bands are synchronously rotated so as to turn the vulcanizing drum and continuously vulcanize the unvulcanized rubber belt molding on the drum.

Abstract: Methods and apparatus for making self-supporting bodies from particulate materials. The apparatus includes a mold with opposed first and second walls defining a particulate chamber therebetween. The second wall is advanceable and retractable toward and away from the first wall. A plurality of chamber reducers may be removably mounted over each of the walls. Thick-walled members can be incrementally built up by pressing successive batches of particulate material at low and high pressures respectively. The chamber reducers can be successively removed between such batches, or can be used to vary the mold for making bodies of different sizes. A long body can be built up in increments, using a shorter mold, by forming a first increment, displacing the increment lengthwise in the mold, adding another batch of particulate material in overlapping relation to the first body increment, and then pressing such other batch to form a second increment bonded to the first. The latter technique is enhanced by applying different forces or pressures to different sections of the second wall along the length of the mold.
