摘要： The present invention comprises methods and apparatus for inspecting a tread. Such methods include providing a tread having a top side and a bottom side, one of the top and bottom sides including a tread feature extending into the thickness of the tread. Such methods further include bending mechanically a transverse extent of the tread relative the tread thickness along a portion of the tread to be inspected about a bending member to form a bent portion of the tread, the portion of the tread to be inspected including the tread feature such that the step of bending expands the tread feature to further expose a depth of the tread feature within the thickness of the tread for inspection. Such further methods include constraining the tread on opposing sides of the portion of the tread to be inspected to maintain the bent portion of the tread in a bent arrangement.

摘要： The invention include methods and apparatus for demolding a tread. The methods include 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 one or more rollers are freely-rotatable and arranged to define a demolding path of the tread extending from the mold. The tread is demolded 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 located a distance from the molding cavity at least equal to approximately 80% of the tread thickness.

摘要： The invention includes methods and apparatus for demolding a tread from a mold. In particular embodiments, such methods include a step of demolding a first end of a tread from a mold to form a demolded portion of the tread, the tread extending lengthwise from the first end to a second end. A further step includes folding the tread such that at least a portion of the demolded portion is arranged overtop a portion of the tread remaining within the mold. Yet a further step includes applying lubricant to the tread to thereby lubricate relative translation between folded portions of the tread. A further step includes demolding additional portions of the tread by sliding at least a portion of the demolded portion along the portion of the tread remaining in the mold with the lubricant arranged between the demolded portion and the portion of the tread remaining within the mold.
