Abstract

A system manufactures a tire assembly. The system includes a core having a cylindrical hub and radially protruding extensions projecting radially outward from the hub, a plurality of internal arcuate members for positioning a reinforcing layer of the about the core, the internal arcuate members each being wrapped with a reinforcement layer, the internal arcuate members being disposed in spaces circumferentially between the extensions of the core, a first side plate for securing the internal arcuate members in place relative to the core; and a second side plate for securing the core and internal arcuate members to each other.

First claim

What is claimed:

1. A method for manufacturing a non-pneumatic tire or wheel, the method comprising the steps of:
providing calendered a reinforcement layer of fabric or cord and rubber compound treatments or sheets;
wrapping part of the reinforcement layer around each of a plurality of internal arcuate members;
laying another part of the reinforcement layer on an outer surface of a core across a full 360 degree circumference of the core;
securing the reinforcement layer in position on the core by positioning internal
arcuate members circumferentially between radial extensions of the core;
fastening the core and internal arcuate members between a first side plate and a second side plate by securing the second side plate to the first side plate, the core, and the internal arcuate members with bolts; and
placing wedges over the parts of the reinforcement layer in depressions between the extensions of the core and the internal arcuate members.

2. The method as set forth in claim 1 further including the step of securing the wedges to the parts of the reinforcement layer by applying pressure.

3. The method as set forth in claim 1 further including the step of placing a shear band component over the parts of the reinforcement layer and securing the shear band component to the parts of the reinforcement layer.

4. The method as set forth in claim 1 further including the step of applying heat and pressure to cure rubber components of the non-pneumatic tire or wheel.

5. The method as set forth in claim 1 further including the step of securing a shear band component to the parts of the reinforcement layer by adhesive.
