PROCEDE DE RECHAPAGE DE BANDAGES PNEUMATIQUES USES AU MOYEN D'UNE BANDE DE ROULEMENT VULCANISEE, ET DISPOSITIF APPLIQUANT CE PROCEDE.

摘要

The invention relates to the retreading of rubber tires wherein a prevulcanized tread is applied to a tire carcass with an interposed vulcanizable bonding layer. The tread and at least the adjacent part of the carcass are enclosed within a close fitting flexible envelope and the resulting blank is subjected to a pressure- and heat-treatment in an autoclave to bond the tread to the carcass. The invention resides in the construction and use of an envelope which is associated with an adjacent reservoir within the autoclave, preferably between the envelope and tire, for the accumulation of possible gaseous inclusions between the inside of the envelope and the blank.
