1. A method of demolding a tread from a mold, the method comprising:
arranging one or more rollers to extend across a transverse extent of a tread molding cavity and across an outer, exposed side of a tread, the tread being at least partially arranged in a tread molding cavity of a mold, the tread molding cavity having a length extending longitudinally from a first end to a second end and including projections for forming void features in a thickness of the tread, where each of the one or more-rollers being freely-rotatable and arranged to define a demolding path of the tread extending from the mold; demolding the first end of the tread from the mold, whereby a remaining portion of the tread remains within the tread molding cavity; arranging the tread at least partially around the one or more rollers; and demolding the remaining portion of the tread from the tread molding cavity along the demolding path such that the tread is initially directed outwardly from a molded position within the tread molding cavity at an initial angle less than 90 degrees from the molded position, the tread continuing along the demolding path until the tread is directed away from the molding cavity in a direction 90 degrees from the molded position at a perpendicular position, the perpendicular position located a distance away from the molding cavity, the distance being at least equal to approximately 80% of the tread thickness, and where the tread at least partially extends around a circumference of at least one of the one or more rollers along the demolding path, where the step of demolding includes translating, in a longitudinal direction, one of the mold or the tread relative the other to demold the tread from the mold cavity. |
