Abstract

Official abstract text for this publication.

The disclosure relates to a molding element of a mold for molding and vulcanizing a tire tread, this tread comprising a tread surface intended to come into contact with the ground when the said tire is running. The molding element includes a rib for molding a groove in the tire tread, the rib being a rounded end.

First claim

Opening claim text (preview).

The invention claimed is: 1. A molding element of a mold for molding and vulcanizing a tire tread, comprising: a rib being able to be molded to a groove in the tire tread, the rib having a rounded end, two cutting means positioned on either side of the rib at a predetermined distance from the rib, each of the two cutting means including a cutting edge, the cutting edge forming an acute angle, a plurality of lamellas positioned between the rib and the cutting means, the plurality of lamellas being shallower than the rib, the rib having a direction of extension X and each lamella having a direction of extension Y, the direction of extension Y of the lamella makes an angle α with the direction of extension X of the rib, the angle α being less than 20°. 2. The molding element according to claim 1 , wherein there is a minimum distance D between the rib and the nearest lamella, the minimum distance is being at least 1 mm. 3. The molding element according to claim 1 , wherein the angle α is less than or equal to 10°.
