Abstract
A twist correction device for a pipe conveyor having an endless transfer belt whose at least part is rounded in a pipe shape enclosing therein a material to be transferred. The device includes a plurality of correction rollers obliquely inclined relative to the transfer direction of the transfer belt and in pressure contact with the outer circumferential surface of the pipe-shaped transfer belt to apply correcting force to the belt for correcting twisting of the belt. The device further includes two roller support frames supporting the plurality of correction rollers and pivotally connected to a stationary support frame rotatably about axes perpendicular to the transfer direction of the transfer belt. The device includes an angle adjusting device provided on the stationary support frame for adjusting rotated angles of the roller support frames about the axes, thereby correcting twisting of the pipe-shaped transfer belt. The angle adjusting device is manually driven or automatically power driven.
