Abstract

L'invention a pour objet un moule de compression (20) pour fabriquer une garniture de frottement comportant une chambre de compression (30) annulaire délimitée au moins par une surface cylindrique intérieure (32) et une surface cylindrique extérieure (34), la chambre de compression étant destinée à recevoir un matériau (22) pour former une pièce moulée (24 ; 124), le moule de compression étant caractérisé en ce qu'il comporte un moyen dit de rupture (50 ; 150A, 150B) pour former une zone de rupture (52 ; 152A, 152B) cylindrique dans la pièce moulée pendant le moulage par compression à une distance inférieure ou égale à 20 mm d'une des surfaces cylindriques intérieure (32) ou extérieure (34).The invention relates to a compression mold (20) for manufacturing a friction lining comprising an annular compression chamber (30) delimited at least by an inner cylindrical surface (32) and an outer cylindrical surface (34), the chamber compression being intended to receive a material (22) to form a molded part (24; 124), the compression mold being characterized in that it comprises a so-called rupture means (50; 150A, 150B) to form a zone of cylindrical rupture (52; 152A, 152B) in the molded part during compression molding at a distance less than or equal to 20 mm from one of the inner (32) or outer (34) cylindrical surfaces.
