    • 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.
    • 织物胎体限定了传送带的基部。 将第一聚合物涂覆或以其它方式设置在织物胎体的外侧上以使第一层厚度固化。 第一聚合物可以是具有增塑剂添加剂的聚氯乙烯树脂,以相对较低的成本提供对带的增加的鲁棒性。 由于当使用某些聚氯乙烯树脂作为输送带的外表面时可能发生的劣化,第二聚合物被设置在聚氯乙烯的固化层上以限定外表面,该外表面构造成与压模的弹性接触 切割或冲压站。 第二聚合物可以是提供改善的弹性的聚酯和具有比第一聚合物更好的耐久性的外表面。
