Abstract: The present invention concerns an endless conveyor belt for a conveyor device, which conveyor belt comprises a belt body that can be transversely deformed between a flat configuration, at rest, and a tubular configuration. This belt body comprises two transition regions over its width which between them define a central belt portion, as well as two side belt portions situated between each of them and the nearby side edge. At least one thickness of the side belt portions is greater than at least one thickness of the central belt portion, forming at least one over thickness region on each of the side belt portions.

Abstract: An endless conveyor belt for a conveyor device, includes a planar body (2) that is transversely deformable into a tubular configuration, the body having a plurality of longitudinal reinforcing members built into the body thereof. The body has an upper layer (10), a portion of the lower surface of which is combined with a lower layer (11). The two layers are made of two different elastomer materials, with the lower layer made of a first elastomer material, whose hardness is greater than that of the second elastomer material constituting the upper layer, and the lower layer includes a plurality of softening recesses (13) that are distributed across the entire length of the lower layer and each of which extend over at least a portion of the body thereof so as to reduce the resistance thereof to longitudinal deformations in order to reduce the resistance to the bending of the conveyor belt into the tubular configuration thereof.

Abstract: An endless carrier belt for a conveyor system, which carrier belt is produced flat from a flexible material, includes a flat body of width L, of central longitudinal plane X and of thickness e, whose top face is designed to support a product to be carried. The flat body contains in its thickness a plurality of longitudinal reinforcing members located in only two regions of the width of the flat body, situated at about a quarter of the way across the width, on each side of the central plane. When formed into a tube, the reinforcing members can be positioned on the horizontal diameter of the cross section of the tube, thus limiting the internal stresses on the structure, especially when the structure is following non-straight paths (corners or curves) in a plane perpendicular to the axes of the endmost rollers of the conveyor on which it is used.
