Claims21
A method for affixing an ethylene-vinyl acetate item to a rubber item, the method comprising:
- placing an at least partially cured ethylene-vinyl acetate item on top of a less than cured rubber item;
- providing a chamber comprising a first material having a first dielectric constant;
- providing a chamber cover, wherein the chamber cover is coupled to the chamber, and wherein the chamber cover comprises an aperture extending through the chamber cover, the aperture fully containing a second material having a second dielectric constant;
- and
- applying microwaves and pressure through the chamber cover to the at least partially cured ethylene-vinyl acetate item and a less than cured rubber item for a predetermined amount of time.

A method for affixing an ethylene-vinyl acetate item to a rubber item, the method comprising:
- placing an at least partially cured ethylene-vinyl acetate item on top of a less than cured rubber item;
- providing a panel comprising a first material having a first dielectric constant;
- positioning the panel between a microwave energy source and the ethylene-vinyl acetate item, the panel comprising an aperture extending through the panel, the aperture fully containing a second material having a second dielectric constant;
- and
- applying microwave energy from the microwave energy source and pressure through the panel to the at least partially cured ethylene-vinyl acetate item and the less than cured rubber item for a predetermined amount of time.
