A machine for manufacturing vulcanized rubber hoses, of the type comprising a pair of heads laying opposite to mandrels which rotate two or more tubular cores supported by bearing elements with fixed rollers on a supporting frame. Alongside the tubular cores a box-type openable heat insulated furnace is provided, adapted to contain the cores wrapped by the hoses to be vulcanized and unloaded by transferring means. The furnace heads have means for supplying electric power to the cores. Means are provided for picking up the cores from the container. The machine is characterized in that the furnace is provided, in at least part of the bottom and of the sides, with through holes which connect the inside with the exterior.
On décrit une machine de fabrication de tuyaux de caoutchouc vulcanisés, du type comprenant deux têtes à l'opposé de mandrins qui font tourner au moins deux noyaux tubulaires prenant appui sur des supports dotés de rouleaux fixes disposés sur un châssis de support. Le long des noyaux tubulaires est disposé un four à isolation thermique, du type boîtier ouvrant, prévu pour confiner les noyaux enveloppé par les tuyaux à vulcaniser qui y sont déchargés par un dispositif de transfert. Les têtes du four sont dotées d'éléments alimentant les noyaux en énergie électrique. Des dispositifs permettent d'extraire ces noyaux de l'enceinte. Cette machine se caractérise par son four où sont ménagés, sur une partie du fond et des côtés au moins, des passages traversants reliant l'intérieur et l'extérieur.
