The method may involve providing an elongated tubular resilient member which is slit longitudinally and circumferentially expanded so as to permit it to receive a lateral edge of the belt. The interengagement may be maintained through resiliently maintained contact alone or by additional means for securing such contact.

Abstract: A belt conveyer and a conveying system using a belt conveyer. The system is designed to convey articles around curves and between vertically and horizontally spaced locations.

The feeder includes an endless belt having spaced, transversely mounted cleats.

Abstract: A conveyor belt of stretchable elastomeric material reinforced by layers of cords which permit an initial stretching of the belt at installation of at least 3 percent. Reinforcing cords are positioned in the belt elastomeric material to generate transverse forces during stretching of the belt which results in the interaction of the material of the belt with the cords. This interaction causes the edge portions of the belt to curl upwardly and form load-retaining walls at the edges. The belt may have a bottom stretchable portion which is reinforced to resist outside transverse forces resulting from the passage of the belt around a curve. A top stretchable portion of the belt has edge portions which bend upwardly to form the load-retaining walls. The edge portions of the belt may curl sufficiently to bring the edges together and they may be connected for enclosing the load on the belt surface.

Abstract: An improved endless flexible conveying element is set forth. The flexible conveying element is of the type adapted to be mounted on a carrier and to conform with a generally curvilinear endless path for orbital traverse of such endless path. The conveying element has an elongated resiliently deformable portion which includes a longitudinally extending portion located laterally intermediate the longitudinal extending side portions thereof. The resiliently deformable portion of said conveying element laterally flexes to permit the belt to follow laterally curvilinear portions of the endless path in an upright position. The resiliently deformable portion has a tendency to spontaneously assume a natural form thereof, which is configured such that the resiliently deformable portion, when mounted on the carrier, is deformed from its natural form in a manner to provide in the side portions a condition of relative longitudinal tension with respect to the central portion.

Abstract: The cleated belt forage conveyor of the invention is directed to a forage belt conveyor in which the belt in service is protected against side discharge of conveyed forage by upstanding and intermittent central cleats and outwardly spaced side cleats. Sealing strips extend above the belt in the spaces between the respective central and side cleats to limit outward movement of the bulk of the forage and an edging extends on each side of the belt to prevent spillover. In the event of some side discharge from the belt to the inside of the lower reach of the belt, a plow overlying the inside of the lower reach of the belt directs the forage for discharge to vibrating deflector plates which deflect the forage to the bottom of the housing of the conveyor to be carried by the cleats to the input side of the conveyor and around the idler pulley for reconveyance.

Abstract: A flexible belt trough type conveyor is directed over a hump having an upwardly angling inclined side defined by belt supporting rails, then over a sprocket or similar rolling support device, and down the declined side of the hump on further rails. At the apex of the hump the belt is tensioned sufficiently to stretch the trough structures and partially or entirely flatten them, creating a loading station for granular materials such as explosives. When the belt has traveled over the apex, the tension decreases and the trough structure returns and automatically separates the granular material into discrete load units separated by the raised edges of the troughs.

Abstract: An endless flexible conveyor belt has a load-supporting portion and two upstanding side walls thereon. The sidewalls are corrugated, each being formed with a plurality of transverse major folds at least some of which have one or more minor or auxiliary folds incorporated in them.

Abstract: A stretchable U-shaped conveyor belt with reinforcing members extending transversely of the belt and spaced apart longitudinally of the belt.

The power belt and conveyor belt are carried by support rollers mounted on frames at spaced-apart positions along the belt path. The frames are fastened to a resilient, flexible spine member which provides for positioning of the frames around vertical and horizontal curves. The U-shaped cross section of the belt is also maintained by U-shaped reinforcing members of high modulus material which are positioned in two spaced layers within the molded body of the belt.
