Title:
METHOD FOR MANUFACTURING A NOISE REDUCING TREAD
Document Type and Number:
WIPO Patent Application WO/2017/056456
Kind Code:
A1
Abstract:
Present invention provide a method for producing a tread for a tire having a plurality of contacting element delimited by a plurality of grooves and a connecting member intended to connect two side faces of adjacent contacting elements, the method comprises at least the steps of: (a) depositing at least one connecting member on a surface of an unvulcanized green tread, (b) introducing the unvulcanized green tread with the connecting member into a mold having at least one molding element having a plurality of rib for forming the groove on the tread, at least two rib side faces and a molding surface, at least one rib having at least one notching portion receiving a guiding member made of a material different from a material constituting the molding element whose modulus at 10% elongation being lower than that of the molding element, the guiding member comprising a guiding slit opening to a top face and extending radially toward the molding surface so as to receive the connecting member, (c) moving the connecting member to a predetermined position in the guiding slit through the guiding slit by green tread, (d) molding and vulcanizing the green tread with the connecting member in the mold, and (e) taking a molded and vulcanized tread out from the mold.
