Title
(EN) TYRE TREAD AND LAMELLA SUITABLE FOR ATTACHING INTO VULCANISATION MOULD TO FORM A SIPE IN A BLOCK OF TYRE TREAD
(FR) bande de roulement et lamelle de bandage pneumatique apte a etre fixee dans un moule de vulcanisation pour former une lamelle dans un bloc de bande de roulement d'un bandage pneumatique
Abstract
(EN)
Described is a tyre tread containing at least one row of blocks arranged in the circumferential direction of the tyre, where at least one of the blocks is provided with one or more shaped 3D sipes in radial direction, and this shaped 3D sipe is delimited by two mutually mating shaped surfaces created by a lamella in the course of vulcanisation. The sipe has shape of a periodically repeating element drawn up into a surface in the direction of the radial plane, wherein the surface is in the radial direction at least once interrupted at a certain interval and replaced by a surface created of the same periodically repeating element shifted by 1/2 of the period. The above periodically repeating element consists of arms interconnected by arcs which after drawing them up into a surface will create parts (14, 16) of a cylinder lateral surface. The surfaces formed at the places of interruption make with the radial plane of the sipe the angles &agr;1 and &agr;2, which are 75 to 90°.
(FR)
L'invention concerne une bande de roulement de bandage pneumatique qui présente au moins une rangée de blocs disposés dans le sens de la périphérie du bandage pneumatique, au moins un des blocs étant doté d'une ou plusieurs lamelles tridimensionnelles dans la direction radiale, cette lamelle tridimensionnelle étant délimitée par deux surfaces de formes mutuellement complémentaires créées par une lamelle au cours de la vulcanisation. La lamelle a la forme d'un élément qui se répète périodiquement et dessinée dans une surface qui s'étend dans la direction du plan radial, la surface étant interrompue au moins une fois dans la direction radiale à un certain intervalle et remplacée par une surface créée à partir du même élément qui se répète périodiquement mais décalée d'1/2 période. Ledit élément qui se répète périodiquement est constitué de bras reliés par des arcs qui, après avoir été dessinés dans une surface, forment des parties (14, 16) de la surface latérale d'un cylindre. Les surfaces formées aux emplacements d'interruption forment avec le plan radial de la lamelle des angles α1 et α2 qui sont de 75 à 90°.
