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 tire assembly about the core, the internal arcuate members being disposed in spaces 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;
laying the reinforcement layer on an outer surface of a core across a full 360 degree circumference of the core;
rotating the core to facilitate the laying step;
securing the reinforcement layer in position on the core by positioning internal arcuate members circumferentially between the extensions of the core;
inserting projections of internal arcuate members through shafts of first and second side plates;
fastening the core and internal arcuate members between the first side plate and second side plate by securing the second side plate to the projections of the internal arcuate members extending through the first and second side plates;
splicing two ends of the reinforcement layer to create a continuous ply about the core; and
placing extruded rubber wedges over 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 rubber wedges to the reinforcement layer by applying pressure.

3. The method as set forth in claim 2 further including the step of placing a shear band component over the reinforcement layer and securing the shear band component to the reinforcement layer.

4. The method as set forth in claim 3 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 4 further including the step of securing the shear band component to the reinforcement layer by adhesive.

6. The method as set forth in claim 5 further including the step of encasing the shear band component with external arcuate members.
