DEVICE FOR PREVENTING A FLEXIBLE TUBLER BELT FROM TWISTING FOR USE IN A TUBLER BELT CONVEYER

摘要

A device to prevent a flexible tubular belt from twisting is for use in a tubular-belt conveyor. A flexible tubular belt is extended between first and second rollers, which are positioned at a certain distance away from each other, and the belt is opened. The belt moving between the two rollers, is supported by sets of support rollers that are radially arranged around the peripheries of the belt in contact and are rotatably mounted to support frames. Twisting of the belt is characterized by varying the angle of a correction roller to a slop located in a direction perpendicular to the direction of the movement of the belt.
