摘要： 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least 300° C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).
