Abstract
A double-scrim belting (10) is described having a first woven scrim (12) and a spaced apart and substantially parallel second woven scrim (14) connected by staple fibers (18) consolidated together through entanglement and integrated with the scrims through entanglement, both entanglements being of the kind typically produced by needling. If desired, a non-woven web of staple fibers is needled to the outer surfaces of the scrims and the thusly formed belting is completely encapsulated in a matrix of elastomeric material 36. If the belting is intended to be used to convey food grade products, preferably an antibacterial agent is incorporated into the elastomeric material to inhibit bacterial growth.
Claims59
A conveyor belting, which comprises:
- a) at least two generally planar and parallel scrim means, each comprising a plurality of substantially parallel textile yarns;
- b) fibrous material provided intermediate the two scrim means, the fibrous material being in the form of discrete staple fibers consolidated together through entanglement of the individual fibers and the discrete staple fibers being integrated with the yarns comprising the scrim means by entanglement of the fibrous material therewith to connect the two scrim means together, both entanglements being of the character produced by a needling operation;
- and
- c) a polymeric material encapsulating the adjacent scrim means and the connecting fibrous material.
