  • Patent number: 4819791
    Abstract: Conveyor belt for bulk material handling. The conveyor belt (1) consists of a central part (2) and two integrated side parts (3, 4) which side parts are from the beginning manufactured angled in relation to the integrated central part in order to give the conveyor belt an increased resistance to bending. The central part (2) is preformed to contain longitudinal and transversal reinforcement in its lower part in order to increase the thickness of the wear resisting material in the upper part. The side parts (3, 4) are provided with wearing resisting material and longitudinal and transversal reinforcement. The side parts are angled at an angle alpha in relation to the central part, which angle in a preferred embodiment is approximately 45.degree. or 90.degree.. The conveyor belt is carried by cables (5, 6), or a number of rollers.
