ABSTRACT:
In a conveyor band which has load-bearing components of expandible plastics material hinged to transverse rods with two or more of the components extending end-to-end across the width of the band between each adjacent pair of rods, interengaging projections and flexible portions are provided at the adjacent ends of the components. Normally the flexible portions are unflexed and the projections space the adjacent ends of the components apart, but in the event of expansion of the plastics material, for example as a result of water absorption, which causes lateral expansion of the components, the flexible portions flex under the effect of the increased pressure exerted on them by the projections and permit the components to move closer together. Thus expansion of the components is accommodated internally of the band, leaving its width unaltered.
