<p>This invention relates generally to a mould segment (1) used in the production of replacement premoulded and precured tyre thread in a flat moulding process wherein the mould segment (1) is provided with an indexing means to align adjacent mould segments to avoid discontinuity or distortion in thread pattern. In this invention the indexing means is provided on the opposing longitudinal edges (14, 15) of the mould segment (1). The indexing means comprises one or more protruded portions (16) on the longitudinal edges (14, 15) or one or more indented portions (18) on the longitudinal edges (14, 15) or a combination of one or more protruded portions (16) and/or one or more indented portions (18) on the longitudinal edges (14, 15). The invention also relates to a method of aligning mould segments in a mould matrix using indexing means on the opposing longitudinal edges (14, 15) of the mould segments. The invention also relates to a method of aligning mould segments in a mould matrix using mould segment (1) of this invention.</p> |
