Abstract: An entraining cleat of rubber or like material for attachment to a flat conveyor belt of an assembly for steep or vertical conveying of loose material is provided. The entraining cleat includes an entraining bar having a lower straight branch and latteral projections extending perpendicularly outwardly from opposite sides thereof above the lower end of the branch. A foot portion includes two profile portions having angular cross-sections extending generally parallel to each other with respective lower branches extending outwardly in opposite directions with flat bottom surfaces for being positioned on the conveyor belt and upper branches having a grooved-shaped space therebetween and upper flat faces for receiving the lower end of the lower branch of the entraining bar within the groove-shaped space and the latteral projections on the upper flat faces for mounting the entraining bar on the foot portion.

Abstract: An endless conveyor belt 10 provided with angled-over entraining cleats 12 as well as lateral corrugated sidewalls 11 serves the purpose of unloading bulk material 1 from a ship 2 in particular, which not only carries the bulk material 1 out of the ship 2 but also picks the same up automatically. The conveyor belt 10 hangs down with both legs 10' and 10" from an upper driving drum 20 within a conveyor framework 3 and runs freely below the conveyor framework 3 in a loop 21 formed merely under the action of the weight of the conveyor belt without application of external tensioning devices. The conveyor framework 3 is lowered so far into the bulk material 1 that the loop 21 shortens in vertical direction and the conveyor belt 10 digs into and picks up the bulk material 1 with the entraining cleats 12. A vertically displaceable delimiting drum 27 in the loop 21 prevents an excessive lateral displacement of the loop 21 as a reaction to the scooping action.

Abstract: A belt conveyor plant for conveying bulk material outdoors and in particular on hilly terrain comprises supporting and locating systems 15,16 for the load section 5 and the return section 6 of its conveyor belt 4, which under omission of a supporting frame extending uninterruptedly between the two terminal stations 2, 3 of the belt conveyor plant are in each case carried by a bearer 14 anchored separately in the soil 7. The conveyor belt 4 sags freely between the bearers 14 arranged with greater mutual spacing of at least 5 meters as in the case of a cableway. Since it is impossible in such case to guide the conveyor belt 4 formed into trough shape, use is made of a so-called corrugated edge belt, i.e. a conveyor belt 4 having a transversely stable belt element 20, whereof the carrying side has installed on it two longitudinally continuous undulant edge strips 21 (FIG. 2).

Abstract: In a conveyor system for bulk materials used for loading and unloading large containers, and particularly ships, including a gantry, a boom pivotally mounted on the gantry, a vertically positioned leg extending from the boom and mounted to rotate relative to the boom and conveyor belt devices movably carried by the gantry, the boom and the leg for conveying the bulk materials, improvements are provided which are characterized by providing a simplified construction of the conveyor system allowing both loading and unloading operations and eliminating the necessity of plural conveyor belts by utilizing a single continuous conveyor belt, spaced guide mechanisms for the conveyor belt carried by the rotating leg and by the boom for allowing the conveyor belt to twist with rotation of the leg relative to the boom, and a motor for selectively driving the conveyor belt in forward and reverse directions for loading and unloading bulk material.

Abstract: A cover belt conveyor in which each of two conveyor belts have lateral corrugated edges or waved ridges of a substantially common height. The conveyor belts are mutually supported on the heads of the waved ridges to form a large conveying space therebetween. By the provision of interengaging profile knobs at the waved ridges which interengage like meshing teeth, engagement of the conveyor belts is maintained without the need for drums or rollers pressing the two belts against each other.

Abstract: A cover belt conveyor including a carrier belt and a cover belt entrained over respective return drums and having proximal runs defining a conveyor path therebetween. The belts have closure strips with a periodic wave form defining wave ridges thereon and profile knobs arranged in longitudinal rows which contact one another to aid in maintaining the closure strips of one belt in a desired relation to the closure strips of the other belt during movement of the belts along the conveyor path.

Abstract: A curved belt conveyor having a generally planar ring shaped belt supported and guided for movement along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of the circle about a predetermined center. In accordance with the present invention, the inner peripheral edge of the belt is engaged by a plurality of guide rollers, each of which is mounted for individual independent movement radially of the arc described by the inner peripheral edge. The rollers are resiliently biased radially outwardly against the edge of the belt.

Abstract: An inlay fabric for transversely stiff conveyor belts having warp threads to be arranged in longitudinal direction of the conveyor belt and relatively stiff weft threads extending transversely thereof. The weft threads have a diameter in the range from 0.2 to 1.0 mm, the density of the weft threads ranges from 60 to 120 threads per 100 mm of fabric length, and the warp threads have a crimp between 6.5 and 22.5%, whereby the inlay fabric has relatively great transverse stiffness together with low longitudinal stiffness and at the same time is suitable to accomodate tensile forces in longitudinal direction.

Abstract: An endless conveyor belt for the conveying of separate articles or packages to be conveyed along a steep incline. The belt is formed with spaced, resilient flaps which extend upwardly from the load supporting surface to engage the conveyed article. If the article slides backwardly on the belt, the flap bends and pivots upwardly so that a roughened surface will tend to retard the sliding movement. After the article is removed, the flap is restored to a position within a recess in the belt surface during the return run.
