premoulee ring rolling for reconstruction of tyres

摘要

Pre-molded ring tread, for the rebuilding of worn pneumatic tyres, that is made up of two pre-molded half-rings, each of which has a curved surface and each delimited, on the lower portion, by an arc and an elongated edge so as to cover the side of the pneumatic tyre. The tread is shaped so as to cover half of the surface of the pneumatic tyre, to be rebuilt obtained by cutting the pneumatic tyre along a plane perpendicular to the rotation axis and passing through the largest diameter.
