ABSTRACT:
A curved belt conveyor, to be used mostly above ground and operating with any desired length, can be operated advantageously without belt band rollers so that no tumbling action can take effect upon the belt band. This makes for long service life, as well as quieter, more uniform and safer operation. Drive is accomplished either via a linear motor drive system acting laterally upon the belt band, said system consisting of magnets arranged on the running wheel carriers and the stators that are firmly integrated into the guide ducts, or where, in the guide ducts, for example, a traction chain runs that is connected correspondingly with the running wheel carriers. The side edges of the belt band are grasped via the running wheel carriers and are so connected with them that one can achieve a swing-motion connection. The belt has a predetermined troughing due to the arrangement of the guide ducts, and that troughing can thus also be altered in accordance with the requirements by changing the arrangement of the guide ducts until it forms practically a closed tube.
