Abstract: A curved conveyor element is provided which comprises outer and inner spaced curved frame members having first and second ends. A pivotal head is rotatably mounted to the frame at one end, a row of rollers being provided in the pivotal head and a second row being secured to the other end of the frame. An endless conveyor belt passes around both rows of rollers, and is driven by a drive attached to the belt by elastic dog members. Removable supporting elements are positioned between the outer and inner frame members substantially coplanar with the conveyor belt. The pivotal head is rotatable to a position above the upper reach of the belt to permit the belt to be installed and removed through a slot defined by the removable supporting elements.

Abstract: A conveyor belt curve comprising two rows of rollers for deflecting or turning an endless conveyor belt. The roller rows each consist of a number of cylindrical rolls. The conveyor belt is driven by means of a driven chain through the agency of chain fixed-entrainment members or elements. The chain is guided within guide rails for the upper and lower chain runs, these guide rails determining the curvature of the curved portion of the conveyor belt curve. The entrainment elements contain rolls or rollers rollingly supported at the guide rails. The endless conveyor belt is held in a tensioned state by means of special tension springs. These springs are formed of an elastomeric material and have a preferred loop-shaped configuration.
