20220388203 · 2022-12-08 ·

A method of curing spokes (10) is provided in which first molds of a first (14) and second series (16) of molds are placed into a platen, and force and heat applied. The platen (12) is opened and the first mold (1(1)) of the first series (14) is moved relative to the platen while the position of the first mold (1(2)) of the second series (16) is kept the same relative to the platen. Force and heat are applied to the molds. The platen (12) is opened, and the first mold (1(1)) of the first series is removed while the second mold (2(1)) of the first series is kept within the platen. A cured spoke is removed from the first mold of the first series.

METHOD AND APPARATUS FOR IMPROVED TREAD SPLICING

A mold for molding a tire tread comprises a plurality of mold segments. Each of the plurality of mold segments includes an integer number of tread pitch repetitions. The plurality of mold segments are structured to be coupled to each other end-to-end so as to form the mold such that the mold includes an integer number of tread pitches. The mold also includes at least one mold end segment positioned on at least one end of the mold and has a mold end segment length shorter than a length of each of the plurality of mold segments.

Method of molding spokes of a non-pneumatic tire using an array of molds

A method of curing spokes is provided in which first molds of a first and second series of molds are placed into a platen press, and force and heat applied. The platen press is opened and the first mold of the first series is moved relative to the platen press while the position of the first mold of the second series is kept the same relative to the platen press. Force and heat are applied to the molds. The platen press is opened, and the first mold of the first series is removed while the second mold of the first series is kept within the platen press. A cured spoke is removed from the first mold of the first series.
