Abstract: The machine for manufacturing vulcanized-rubber tubes has a pair of heads arranged oppositely with respect to mandrels which rotate two or more tubular cores, supported by supporting elements with fixed rollers on a supporting frame. The tubular cores are contained in a thermally insulated box-like container, wrapped in the tubes to be vulcanized and unloaded by transfer means. The container has heads for supplying electrical power to the cores. Devices are provided for removing the cores from the container. The machine also has a carriage which can move along guides which are parallel to the cores, and a mechanism for wrapping the cores simultaneously with spirals of the materials to be used to manufacture tubes.
