Problems solved by technology

[0005] A disadvantage of this prior art lies in the fact that dedicated laser etching lines are complex and expensive to implement
Also, as the tires wear out, the encoding matrix symbols become unrecognizable

Embodiment Construction

[0067] In the ensuing description, substantially the same or similar elements will be denoted by the same reference numerals.

[0068] figure 1 A mold 3 is shown comprising:

[0069] - a housing 4 intended for molding the sidewall 10 of the tire 1 , said housing comprising a housing 40 in which the mold element 2 is installed;

[0070] - the closed section 30 is held (clamped) by the conically thinned strip 31 ;

[0071] - Mold element 2 comprising markings 20 .

[0072] The mold element 2 is a removable insert intended to be mounted in the housing 40 of the housing 4 . In a non-limiting embodiment, said insert 2 is made of aluminum. This makes it possible to have a plastically removable insert and thus makes it easier to create markings in the insert 2 . The markings 20 are intended to be molded on the tire with coded matrix symbols 5 in contrast to the sidewall of the tire. The indicia 20 thus correspond to the inverse shape of the coding matrix symbols 5 to be imprint...

Abstract

The invention relates to a mould element (2) for a tyre mould comprising a mark (20), said mould comprising a shell intended to mould the sidewall (10) of the tyre (1). The mould element (2) is characterised in that it takes the form of a removable insert intended to be mounted in a housing in the shell, and in that the mark (20) is intended to mould an encoded matrix symbol onto the tyre, such that it contrasts with the sidewall of the tyre, said mark (20) comprising a first set of cavities (201) or projections (202) designed to mould the dark parts of the encoded matrix symbol (5).

Description

technical field [0001] The invention relates to a mold element comprising a marked tire mold comprising a shell intended for molding the sidewall of a tyre. [0002] The invention also relates to a tire mold in which said mold element is installed. [0003] Finally, the invention relates to a method of manufacturing a mold element of said tire mold. Background technique [0004] From document EP1636117 it is known to use a coding matrix symbol on the tire sidewall containing information such as the unique number of said tire, the website of the tire manufacturer etc. The coding matrix symbols consist of dark and light parts and are etched directly on the sidewall of the tire after it has passed through all stages of manufacture and all qualification tests. After manufacture, each tire is placed on a dedicated line for the manufacture of coded matrix symbols, which performs various steps including, inter alia, positioning the tire on the production line, reading the Positi...
