Abstract

DC60 (03/09/56) The raw tire (20) is inserted into the mold (16), where the axle (18) and the blade (22) are also placed in the mold. to put it down The diameter of the insert axle (18) is reduced and the blade (22) is flattened after it is inserted. The diameter of the insert axle (18) is increased, which allows the inner surface of the inner tube (8) of the raw tire (20) to be attached to the body. On the insert axle plate (36), the inner tube is positioned between the insert axle (18) and the surface of the socket (34). By adding gas, the blade (22) inflates gradually. The mold (16) will be held together. This will further increase the internal pressure of the blader (22). part of the skin surrounding the inner circle In the raw tire (20) that is not supported on the insert axle (18) is supported on the blade (22), the raw tire (20) is heated. By conducting heat from the mold (16) and the blade body (22), the raw tire (20) is inserted into the mold (16), where the insert rod (18) and the blade (22) are placed. ) was placed in that mold as well. to put it down The diameter of the insert axle (18) is reduced and the blade (22) is flattened after it is inserted. The diameter of the insert axle (18) is increased, which allows the inner surface of the inner tube (8) of the raw tire (20) to be attached to the body. On the insert plate (36), the inner edge rests between the insert core (18) and the surface of the socket (34). By adding gas, the blade (22) inflates gradually. (16) will be held together This will further increase the internal pressure of the blader (22). part of the skin surrounding the inner circle In the raw tire (20) that is not supported on the insert axle (18) is supported on the blade (22), the raw tire (20) is heated. By conducting heat from the mold (16) and the blade body (22).

Claims (1)

1. The process of manufacturing a tire consists of the following steps: (1) forming the raw tire, which includes the tread, sidewall, and bead, which include the core and apex; (2) inserting the raw tire into a mold; and (3) heating the raw tire to a state in which the outer surface of the raw tire is pressed against the face of the mold, part or all of the inner surface of the bead is pressed against the rigid core placed in the mold, and part of the inner surface of the raw tire that is not pressed against the core is pressed against the soft brader placed in the mold, where the diameter of the core can be reduced and increased, and the end of the core is positioned between the upper surface of the core of the bead and the end of the apex in the radial direction.
