Abstract
A multi-ply elastomeric belt is produced by tensioning fabric over a lower mold section, elastomeric enveloping said fabric under pressure to form a so called "pulley ply" section, inverting said ply, tensioning at least one fabric member over said ply and elastomerizing the fabric to form at least a belt section, a continuous belt can be made.
Claims5
A method of making a fabric reinforced belt comprising spreading a release material on a flat surface, placing at least one fabric reinforcing member under tension on the release material, forming a pressurizable cavity over said fabric reinforcing member by locking the cavity member having at least one injection opening and a top and side closure means, filling to pressurize said cavity with an elastomeric precursor to encapsulate the fabric, setting said precursor to form a belt ply, inverting said ply to expose the side in contact with said release material, placing at least one other fabric reinforcing member on the exposed side of said ply, forming said pressurizable cavity over said ply by locking said cavity member, filling to pressurize said cavity over said ply with an elastomeric precursor and curing said precursor to form a multiple ply belt having the plies bonded together.
