Abstract: An insert (36) is designed to be incorporated in the composition of a fitting element (24) and to form part of the molding surface (40) of the fitting element, the molding surface comprising at least one intersection (32) of at least a first (42) and a second (44) projecting pattern. The insert comprises a junction (46) which is designed to be joined with a molding element (38) integral with the body (34) of the fitting element, the junction (46) dividing the second pattern (44) into a first (48) and a second (50) part, the insert (36) forming the first pattern (42) and the first part (48) of the second pattern (44), and the molding element (38) forming the second part (50) of the second pattern (44), the junction (46) going away from the intersection (32).

Abstract: A curing mold (10) for a tire comprises: a plurality of circumferentially distributed sectors (18) that are intended to mold the tread of the tire, at least one sipe blade (40) intended to mold a void in the tread, the sipe blade extending over two adjacent sectors (18) such that the sipe blade comprises a part (40a, 40b) in each of the two sectors, the two parts of the sipe blade being separated, in the closed position of the mold, by a space (26) that creates flash during the curing of a tire, the parts of the sipe blade comprising cutting means (38) that are able to cut off the flash during the opening of the mold.
