Abstract
A tubular belt conveyor system includes a conveyor belt having a cross-sectionally closed, curvilinear, tubular configuration including a zone of overlapping edge portions. A plurality of support and guide assemblies for the conveyor are situated along the conveyor path. Each assembly includes a plurality of support and guide rollers held about the cross-sectionally closed conveyor belt in a contacting relationship therewith. In each assembly one roller is in engagement with the cross-sectionally closed conveyor belt at the edge overlap. The closed tubular configuration in each length portion of the conveying path has an oval cross section. The support and guide rollers force the conveyor belt into the closed tubular configuration of oval cross section. The first support and guide roller of each assembly is settable onto the zone of overlapping edge portions.
