Methods of manufacturing a conveyor belt (126) include applying a rubber composition (114) to a first side of fabric reinforcement (112) and scattering productive thermoplastic elastomer pellets (106) onto a second side of the fabric reinforcement to produce an uncured belt structure (120). The uncured belt structure (120) is continuous fed into a double belt press (116) to press the productive thermoplastic elastomer pellets (106) together with the fabric reinforcement (112) to produce an uncured belt (128). Uncured belt (128) is then heated in the double belt press (116) to a temperature of at least 300° F. and maintained in the double belt press (116) under a pressure of at least 12 psi and a temperature of at least 300° C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).

Belting for use in a conveyor. The belting includes a fabric base and an environmentally friendly rubber composition. The environmentally friendly rubber composition is applied to at least one surface of the fabric base. The environmentally friendly rubber composition includes a rubber component, a filler, a processing oil and a vulcanizing agent. The filler is provided at a concentration of between about 50 and 150 parts per hundred weight of the rubber component. The processing oil is substantially devoid of aromatic oil. The processing oil is provided at a concentration of between about 20 and 60 parts per hundred weight of the rubber component. The vulcanizing agent is provided at a concentration of between about 1 and 10 parts per hundred weight of the rubber component.

A fabric carcass defines the base of a conveyor belt. A first polymer is coated or otherwise disposed over an exterior side of the fabric carcass to cure with a first layer thickness. The first polymer may be a polyvinyl chloride resin with a plasticizer additive to provide an added robustness to belt at a relatively low cost. Due to deterioration that may occur when certain polyvinyl chloride resins are used as the exterior surface of the conveyor belt, a second polymer is disposed over the cured layer of polyvinyl chloride to define an exterior surface that is configured for resiliently interfacing with a die press of a cutting or stamping station. The second polymer may be a polyester to provide improved resiliency and an exterior surface with better durability than the first polymer.
