Needled felt and monofilament fabric conveyor belt

Abstract

A conveyor belt construction is disclosed comprising at least one layer of carded non-woven material and one layer of woven fabric that are needled together to form a carcass structure. The layer of non-woven material is carded so that a substantial portion of the staple fibers are oriented in a first direction. The layer of woven material has multifilament warp fibers and monofilament weft fibers. The two layers of material are layered on each other and needled together to form a multi-layer carcass. The carcass is then impregnated with an elastomeric material, resulting in a belt having low operating noise, high lateral strength, and good resistance to belt fastener pull-out. A second non-woven layer can be applied to the woven layer such that the woven layer is sandwiched between the non-woven layers. A method for manufacturing the multi-layer belt is also disclosed.
