Abstract

The present invention relates to a molding element for molding a cut in a tread of a tire. The molding element includes an assembly means, this assembly means being able to connect this molding element to another molding element to form a set of molding elements. This set of molding elements is intended to be attached inside a mold.

First claim

1 . A plurality of molding elements inside a mold, comprising:
an assembly of the plurality of molding elements, each of the plurality of the molding elements being able to mold a cut in a tread of a tire, wherein each of the plurality of molding elements include an assembly means the assembly means being able to connect the plurality of the molding elements to another molding element to form part of the set of the plurality of the molding elements, and the assembly means is arranged at a lateral wall of the molding element, the assembly means including a receiving slot being configured to receive the other molding element, and in that the molding element is a blade.

2 . The plurality of molding elements according to claim 1 , wherein the receiving slot is arranged in a part that protrudes from the lateral wall of one of the plurality of molding elements.

3 . The plurality of molding elements according to claim 1 , wherein the receiving slot is inclined with respect to the lateral wall of one of the plurality of the molding elements.

4 . The plurality of molding elements according to claim 1 , wherein one of the plurality of molding elements includes a transverse wall substantially perpendicular to a lateral wall of the one molding element, the one molding element includes a stud and on the transverse wall.

5 . The plurality of molding elements according to claim 1 , wherein the blade has an additional thickness and in that the assembly means is arranged in this additional thickness.

6 . The plurality of molding elements according to claim 1 , wherein all or some of the plurality of molding elements of the set are blades of a “teardrop” type each including an additional thickness at one of their ends, this additional thickness including an assembly means, and in that the set of elements includes an assembly of at least two “teardrop” type blades.

7 . The plurality of molding elements according to claim 1 , wherein one of the plurality of molding elements includes a transverse wall substantially perpendicular to a lateral wall of the one molding element, the one molding element includes a hollow on its transverse wall.
