FIELD: tire industry; rubber industry.
SUBSTANCE: invention relates to production of pneumatic tires and it can be used in tire and tire repair plants and for local vulcanization in rubber industry. Proposed prepressing device for vulcanizing press has fixed base, movable support plate, heating plate and elastic diaphragm connected with base over outer ad inner diameter by pressure members to form sealed chamber filled with heat carrier. Movable support plate is made in form of metal ring with cavity for fitting ring made of heat insulating material and for collecting resins liberating from heat-insulating material under action of temperature. Ring of heat-insulating material projects over metal ring by 1.5-2.0 mm, forming guaranteed air clearance and isolating heat flows between metal members of prepressing device and heating plate.
EFFECT: increased service life of elastic diaphragm and improved reliability of device in operation.
