Embodiment Construction

[0030] exist figure 1 A perspective view of an advantageous embodiment of the bag-annular system (1) according to the invention is shown in . The rim-like support structure (2) consists of a ring (3) which is connected to the central piece (5) by means of four spoke-like struts (4). The ring ( 2 ) has a circumferential groove ( 6 ) on its outer side in which the bladder ( 7 ) is in a retracted state.

[0031] figure 2 Shows figure 1 A cross-section of an embodiment of the balloon-annular system (1) according to the invention is shown. The bag (7) is located in the surrounding groove (6) and is fastened on the ring (3) by means of the fastening structure (8). The struts (4) are configured tubular such that they connect the cavity (9) in the ring (3) with the cavity (10) in the central piece (5). By means of the pipeline system thus defined, the medium required for the process step can be led to the bag (7) via the connection (11) through the carrier. The bladder (7) can ...

Abstract

The invention relates to a method and to a device for vulcanizing tires. An expandable bellows is used to press the tire to be vulcanized against segments of a mold. The bellows (7) is arranged on a carrier (2) which has an annular design.

Description

technical field [0001] The invention relates to a method for vulcanizing tires, in which method the tire to be vulcanized is loaded into a mold in the region of a tire heat press, and in which the mold is heated, And in the method, the fluid for heat transfer is directed into the area of ​​the inner surface of the tire. [0002] The invention also relates to a device for vulcanizing tires, the device having at least one heatable mold for the tire to be vulcanized and a guide device for a fluid provided for heat transfer, wherein the guide device Able to connect to the sac. Background technique [0003] Heat presses known hitherto have cushion-like inflatable flexible elements as bladders. Aeration is usually achieved by means of compressed air and / or hot steam. During vulcanization, the internal pressure of the bladder is typically in the range of 10 bar to 30 bar. [0004] The bladder has a diameter similar to the outer diameter of the tire. The force generated by the ...
