Zusammenfassung: | A mold segment (3, 23, 45) is disclosed comprising a tread molding element (19) for manufacturing a tire. The tread molding element (19) comprises a shell (55) and an infill (57). The shell (55) has i) a first wall with a negative tread pattern extending from its external surface for molding the tread, ii) a second wall opposed to the first wall, and iii) lateral walls (59). The infill (57) is a fluid-permeable structure defining a fluid-permeable infill. At least one selected from a lateral wall and the second wall comprises at least one fluid passage (61) passing through the lateral wall or the second wall and is fluidly connected to or is open to the fluid permeable infill. Also, a segmented tire mold assembly (1) comprising such a mold segment (3, 23, 45) is disclosed. |
