Abstract:
A conveyor belt comprising a plurality of link assemblies connected together by a plurality of link shafts. The conveyor belt includes a plurality of first guards with each first guard connected to one end of one link assemblies and encompassing one end of one of the link shafts for protecting the end of the link shaft and substantially preventing the end of the link shaft from engaging objects during the operation of the conveyor belt. A plurality of second guards are connected to the opposite end of the link assemblies for encompassing the opposite ends of the link shaft for protecting such opposite ends and substantially preventing such opposite ends from engaging objects during the operation of the conveyor belt. The link shafts extend through openings provided in the link assemblies and each opening is formed on a radius larger than the radius of the links shaft for providing shaft rocking surfaces so that the link shafts roll on the shaft rocking surfaces for substantially reducing rotating friction between the link shafts and adjacent portions of the link assemblies. Each link assembly comprises at least two modules which are positioned in an end-to-end relationship in the assembled position of the link assemblies. The modules in one set of link assemblies are formed of a plurality of whole links, and the modules in one other set of link assemblies are formed of a plurality of whole links with last link in each module to be placed near the last link in each module to be placed near the last link in an adjacent module in the assembled position of the link assembly comprising a half link. The sets of link assemblies are alternatively disposed in the conveyor belt so that every alternate row of connected links comprises only whole links with no spacing or joints between modules.
Abstract:
An apparatus and method for producing a conveyor belt made of urethane having reinforcement embedded therein which reinforcement permits the stretching of the belt under controlled conditions. The reinforcement consists of a fabric or a plurality of aligned strands that are embedded in the urethane body of the belt proper that allow for a controlled stretch in the conveyor belt under such fabric or cords limit the stretching of such belt.

An apparatus and method for producing a conveyor belt made of urethane having reinforcement embedded therein which reinforcement permits the stretching of the belt under controlled conditions. The reinforcement consists of a fabric or a plurality of aligned strands that are embedded in the urethane body of the belt proper that allow for a controlled stretch in the conveyor belt until such fabric or cords limit the stretching of such belt.
Abstract:
The present invention is directed to a conveyor belt system for transporting materials by directly driving a conveyor belt. This is accomplished by directly driving a plurality of clips attached at their inner end to the belt and securedly coupled at their outer end to a pair of continuous cylindrical cables. Even though the belt is directly driven, the subject conveyor system can effect continuous relative movement between the conveyor belt and cables, thereby compensating for differences in the respective lengths of said belt and cables and in the configuration of the respective drives. This is accomplished in great part by the novel construction of clips of this invention which is designed for facilitating secured engagement with the cables and effective and efficient movement of the conveyor belt. This results in the continuous, uninterrupted transportation of the materials carried by the conveyor belt for extended periods of time.
Abstract:
There is disclosed a conveyor-belt reeling device comprised of an open box frame having vertical rollers laterally adjustable at one end, and an axle or mandrel comprised of collapsible members, each end of which is positioned within suitable recesses provided in circular discs wherein one end of the axle extends through the frame for connection to a drive mounted externally to the frame and wherein the other end of the axle is positioned within a pivotally mounted opposite frame member and wherein a cradle including rollers is provided which extends across the width of the frame capable of raised or lowered by means of an integral lifting apparatus.
Abstract:
A conveyor comprising a pulley (5,6) supported belt (1), which forms a tubular section when conveying materials. Material (4) is fed into the belt (1) by means (7) discharging below the level (CL) at which the belt is formed into a tube, but above the point which the line of the angle of repose of the material (4) being conveyed would be tangent to the inner face of the belt (1), ensuring that the tubular section is completely filled. The material (4) is conveyed to a discharge pipe (8) where the belt looses its tubular shape, causing the material to be discharged. A sleeve (9) may be provided to support the belt on vertical or inclined sections, and to ensure the tubular section is properly sealed.
Abstract:
A method and device for preventing a flexible tubular belt from twisting for use in a tubular belt conveyer are disclosed. A flexible tubular belt is extended between first and second rollers, positioned at a certain distance away from each other, on which the tubular belt is opened, and the belt moving between the two rollers in the tubular form is supported by sets of support rollers which are radially arranged around the peripheries of the belt in contact therewith and are rotatably mounted to support frames. Twisting of the belt is prevented by means which varies an angle of a correction roller extending in a direction substantially perpendicular to the direction of movement of the belt in contact therewith. The correction rollers may be disposed in contact with the bottom and/or sides of the belt.
Abstract:
An endless conveyor belt has an elastomeric body and a tension resistant member embedded therein. The tension resistant member comprises a plurality of spaced sets of three textile or metal cords each which extend longitudinally through the belt body and are substantially parallel to the faces of the belt. The cords are spaced from each other to outline a portion of the belt which has a substantially equalateral triangular shape in cross-section with the cords at the apices.
Abstract:
A wire mesh band or belt with mutually crossing warp wires and weft wires for a conveyor system with grooved support rollers is provided with downwardly extending protrusions. The protrusions are warp wire free providing great flexibility for the band in the longitudinal direction. The protrusions can be formed in all the weft wires or only in selected strengthened weft wires with the remaining weft wires woven into the fabric after the protrusions are formed.
Abstract:
A conveyor belt is disclosed of the type adapted to be supported and driven by a pair of wire ropes at or adjacent its edges. The belt comprises a body of rubber reinforced by at least two sheets of fabric embedded therein. Each sheet of fabric includes transverse filaments arranged in two planes and intimately bonded to the rubber. The transverse filaments are of specified size and elasticity. The combination of these physical characteristics of the filaments and their location in the rubber body result in the transverse filaments and the rubber acting together in the manner of an I-beam in resisting transverse loads, both compressive and tensile forces produced by transverse bending being carried principally by the filaments while shear forces are principally taken by the rubber.
