Abstract
Embodiments of the invention include methods for reducing deformation of a sipe-molding member () arising during manufacturing operations, and sipe-molding members () comprising a sipe-forming portion () and a plurality of stiffening members () spaced along the sipe-forming portion. The sipe-forming portion () has a length extending in a lengthwise direction of the sipe-molding member (), a height configured to extend into a depth of a molding cavity, and a thickness extending perpendicular to both the length and height. The sipe-molding member () is configured to form a sipe having a thickness commensurate with the thickness of the sipe-forming portion, a length formed by at least a portion of the length of the sipe-forming portion, and a depth formed by at least a portion of the height of the sipe-forming portion. Each of the plurality of stiffening members () extend outwardly from the thickness of the sipe-forming element. Further embodiments include methods of forming a molded tire tread.
