REMOVABLE DEVICE FOR MOLDING A FLEXIBLE WALL IN THE GROOVE OF A TIRE PATTERN

摘要

The invention relates to a tire baking mold including at least one filling member (21) for molding the tread of said tire, the filling member (21) including at least one bead (210) for molding a groove in the tread. The baking mold comprises at least one insert (10) defining a portion of the bead (210), said insert partially or totally defining a slot (1) extending into the depth of the bead. The slot (1) is oriented substantially perpendicularly to the bead. The slot (1) is adapted for molding at least one flexible wall having a reduced thickness resulting from the material of at least one wall of the groove molded by the bead.
