Embodiment Construction

[0047] definition

[0048] "Tire" means an elastic tread of all kinds, whether or not it is subjected to internal pressure.

[0049] "Tread" of a tire means a quantity of rubber compound delimited by side surfaces and two main surfaces, one of which is intended to come into contact with the ground when the tire is running.

[0050] "Tread pattern" means the surface and volume arrangement of the rubber compound at the outer surface of the tyre, intended to provide contact with the running surface and shaped so as to enable adjustment of the running properties of the tyre. The tread pattern also allows the tread or some other area of ​​the tire, such as the sidewall, to be given an attractive appearance.

[0051] "Mold" means a collection of separate molding elements which, when brought together, enable the definition of an annular molding space in which a tire may be vulcanized and molded.

Abstract

A cutting method for a semi-finished mould element (1) intended to supply sectors (2) of a mould for moulding and vulcanising tyres, said mould element (1) comprising at least one pair of male fastening members (3) on each side of a moulding face (4) designed to form the patterns of the tread of the tyre to be moulded, said method comprising the following steps: aligning and indexing the semi-finished mould element (1) on a fastening support (10) provided with indexing markings (14, 15) and female fastening members (12) corresponding to those of the mould element; fastening the indexed semi-finished mould element (1) to the fastening support (10) using the male fastening members (3) and female fastening members (12); cutting the sectors (2).

Description

technical field [0001] The invention relates to a method of manufacturing a molding element of a mold intended for molding a tire provided with a tread comprising a circumferentially arranged tread pattern. More particularly, the invention relates to a cutting stage aimed at separating the segments commonly obtained during the molding operation. Background technique [0002] The manufacture of tire molds and the manufacture of the components of these molds involves many steps (often very complex) and high production and material costs. Additionally, and importantly, all the components incorporated in the mold may have a high level of precision, all of which makes the operation of designing and producing the mold particularly tricky. [0003] In order to optimize the process without adversely affecting the quality, it is necessary to consider all the components that make up the mold as well as all intermediate steps and operations. [0004] Therefore, there still exists a n...
