20190061090 · 2019-02-28 ·

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.

Treads and methods for making a retreaded tire

Particular embodiments include a retreaded tire and a method for retreading a tire. A method may include providing a tire tread having a thickness and a width with grooves extending into the thickness from a tread top side, and providing a tire carcass having an annular tread-receiving side. The method may include applying the tread to the tire carcass with a layer of bonding material arranged between the tread and the tire carcass, and evacuating a gas from between the tire carcass and the tread bottom side through an aperture extending through the tread thickness, the aperture being formed by piercing the tread thickness with a suctioning member arranged in operable communication with a vacuum source, and bonding the tread to the tire carcass. In particular embodiments, portions of the bottom side of the tread beneath the grooves are not bonded to the tire carcass or the bonding layer.
