Power transmission belt

1. A method of manufacturing a belt comprising the steps of:

laying up a first elastomeric layer of a belt build on a mandrel;

laying up tensile cords on the first elastometic layer;

laying up a second elastomeric layer on the first elastotneric layer;

laying up a non-woven region on the second elastomeric layer;

placing the belt build in a mold;

evacuating the air from inside the mold and holding;

increasing the steam pressure on a mold outside shell;

increasing the steam pressure inside the mold;

curing the belt build;

venting gases through the non-woven region during curing;

decreasing the steam pressure inside the mold to atmospheric pressure;

decreasing the steam pressure outside the mold to atmospheric pressure;

quenching the mandrel in a fluid;

separating the belt build from the mandrel; and

cutting the belt builct to predetermined belt widths.

2. The method as in claim 1 , comprising the step of evacuating the air from inside the mold and holding for approximately 1 to 5 minutes.

3. The method as in claim 2 , comprising the step of increasing the steam pressure on the mold outside shell to a range of approximately 175 to 235 psig.

4. The method as in claim 3 , comprising the step of increasing the steam pressure inside the mold to a range of approximately 85 to 210 psig after approximately 2 to 10 minutes.

5. The method of in claim 4 , comprising the step of curing the belt build for approximately 10 to 20 minutes.

6. A method of manufacturing a belt comprising the steps of:

laying up a first elastomeric layer of a belt build on a mandrel;

laying up tensile cords on the first elastomeric layer;

laying up a second elastomeric layer on the first elastomeric layer;

laying up a non-wovan region on the second elastomeric layer;

curing the belt build;

evacuating gases generated during curing through the non-woven region; and

cutting the belt build to predetermined belt widths.
