<p>A tread for the recapping of tires is provided with a roughened internal surface simultaneously with the shaping of profile on its external surface in a vulcanizing form. The internal surface can be roughened by placing against the body of raw rubber in the form of a latticework, a plate with regularly or irregularly distributed projections or a composite deforming structure. The internal surface of the prefabricated tread can be sealed from the atmosphere by a foil which is applied to the internal surface directly in the form or subsequent to removal of tread from the form.</p> |
