Abstract
A vulcanizer and method for vulcanizing sheets of unvulcanized elastomeric material is presented in which the sheets are formed from generally rectangular small sections of unvulcanized material where the edges of the sections are tapered and mated together along their maximum dimension to form longitudinally extending seams within large sheets. The sheets are wrapped onto a series of concentrically assembled mandrels having different diameters, which serve as individual supports for the multiple wraps of sheet material. Each mandrel is received within the mandrel of the next larger diameter and is supported within the vulcanizing chamber by self-supporting mounting devices or carriage.
