The invention relates to a device for controlling and monitoring a conveyor belt which is made of rubber or a rubber-like plastic material and preferably provided with embedded reinforcements. By overlapping of the longitudinal edges of the conveyor belt the belt can be closed such that it forms a tubular conveyor belt which is supported on all sides by idler wheels. The device also comprises at least the following components: at least one detectable element which is integrated into the conveyor belt and notably takes the form of several elements which in the longitudinal and/or transverse direction are positioned at distances from each other; and at least one scanning unit with which the precise position of the belt can be determined in a non-contacting manner by detection of the element or elements. The device provided for by the invention is characterized in that the detectable element is an induction loop and/or a transponder, a metal particle or a permanent magnet. The scanning unit is advantageously configured as a system of several detector elements which form a detector chain.

Device for controlling and monitoring a conveyor belt, notably a tubular conveyor belt

The invention relates to belt ( ) for a conveyor. The inventive belt is made of rubber or a plastic similar to rubber and is provided with incorporated traction carriers ( ) in the form of cables or cords that are made of steel. The inventive conveyor belt comprises, in relation to its total width (B), a center part (A) and two side parts (A&prime;). The invention is characterized in that the center part (A) is interchangeable as a result of a joint ( ) between both side parts ( &prime;). Various embodiments of said joint ( ) are described.

Belt for a conveyor

A device for transporting materials along supporting rollers including a conveyor belt extending in a longitudinal direction. The device has two spaced longitudinal edges and a tensile fabric layer embedded within the conveyor belt made of a textile, a cord fabric or a synthetic cord fabric. The supports extend in the longitudinal direction, and the conveyor belt is adapted for being rolled into a tubular belt, wherein the two longitudinal edges overlap each other and are supported by the supporting rollers. Stiff textile reinforcements are embedded within the conveyor belt on a side of the fabric layer facing the support rollers. The textile reinforcements are oriented transverse to the longitudinal direction.
