| 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. | ||||||

| 190 | Method for making prestressed tubular belt | US11744941 | 2007-05-07 | US07419558B2 | 2008-09-02 | Alex Mindich |
| A method for manufacturing a self-closing tubular belt with predetermined compression forces at a longitudinal joint comprises winding a plastic material onto a small mandrel such that the plastic material thickness is not more than the height of a mandrel spiral rib, curing the plastic material, and removing the plastic material from the small mandrel, resulting in the plastic material being in a form of a spiral rubber spring having gaps between its twists. The resultant rubber spring is then wound on a larger mandrel thereby forming winding gaps. These winding gaps are then filled with a raw filler material, and these are processed so that all turns of the rubber spring are joined together monolithically. This is removed from the mandrel by making a longitudinal split in the spring, producing the tubular belt having prestressed regions formed by the spring, and resisting portions formed by the filler material. | ||||||

| The particulate material handling system comprises a tube, an endless belt that passes through the tube and returns outside of the tube, and a flighting that is suspended a predetermined distance from the belt through the entire length of the tube. The distance may be varied for the various materials being handled. An intake hopper is mounted at one end of the tube for receiving the material to be moved and a discharge spout is mounted at the other end of the tube for discharging the material from the tube. The endless belt and flighting are driven such that their speed may be varied and such that their relative speeds are synchronized to drive the material at substantially the same speed whether it is being carried by the belt or the flighting. The combination of the belt and the flighting drives the material through the tube, minimizing damage to the material, which may be granular fertilizer, pulse crops, grains or other particulate material. | ||||||
