Estimating the term…
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.
A conveyor belt apparatus comprising a belt band having upper and lower belts guided on supporting frames and around deflection rollers, the belt band being driven by a linear motor drive system arranged along the belt band, plural upper and lower guide ducts running bilaterally in a longitudinal direction, each guide duct having an inner and an outer side, said outer side facing away from the belt band, plural stators arranged at intervals on the outer sides of each upper guide duct, a recess formed in the longitudinal direction along the inner side of each guide duct, plural guide devices within each recess abutting each guide duct, a carrying spar extending from each guide device for connecting with first and second side edges of the upper belt and the lower belt respectively, and plural magnets supported by the carrying spars for interaction with the stators.
