Abstract:
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.
