Abstract
Solid woven conveyor belting is produced by a process which includes the steps of subjecting the fabric carcass to a plurality of alternating changes of direction while immersed in a bath of impregnant material, and then heating the carcass to gel the impregnant. Each of the alternating changes of direction are effected by causing the carcass to follow a generally curved path whose radius of curvature is appreciably less than 75 mm. Prior to immersion, a synthetic polymeric yarn-containing carcass is subjected to a shrinking treatment effective to close the interstices of said carcass to some extent to reduce the impregnant material expelled upon subsequent heating to gel the impregnant.
