Patent ID: 6991692

Claim:
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.
