Abstract
A sculptured drum for a retread process that has an inner radial section with a central axis that extends in an axial direction. The sculptured drum has a plurality of support members that extend outward from a drum outer surface in a radial direction and that are located outward from the inner radial section in the radial direction. A tread that has a plurality of grooves is supported by the sculptured drum during a brushing process and pass across the sculptured drum such that some but not all of the grooves have one of the support members disposed therein. The support members when disposed within the grooves do not completely fill the grooves, and when disposed within the grooves engage a lower surface of the tread.
