Title: Conveyor system using links supported on rollers - has two parallel rails each supporting rollers arranged at right angles
IPC: B65G21/22
Filed: 1976-09-10
Abstract: The conveyor system uses links each supporting pairs of rollers set at right angles to each other and a pair of support rails. Each link carries two pairs of rollers (14, 16, 20, 22), the pairs being axially separated and set at right angles so that the link is constrained to move axially by the rollers bearing on orthogonal faces of two rails placed diagonally with respect to the vertical. The rails can be of rectangular, square or circular cross-section, and can be separate or formed as a connected pair. The links can be inclined as required during the movement by varying the angle of rails.
