Abstract: A conveyor belt system having an improved pulley is disclosed in which the improved pulley includes a roller having grooves of varying width machined into the cylindrical surface of the roller to form raised guides or lands of equal width therebetween which spiral outward relative to the center of the roller with decreasing pitch. The contacting surface of the guides is operative to engage a conveyor belt or webbing passing over the pulley and the varying pitch of the guides allows for the quick centering of unaligned belts or webs. The roller may be machined to have more than one helical guide spiralling outward from the center of the cylindrical surface of the roller at one time. The guides may be squared, chamfered or rounded and may optionally contain serrations. The roller may additionally be machined to taper slightly from its center to the respective ends thereof. Alternatively, helical grooves of equal width may be formed in place of the guides in the surface of the roller and inlaid with conveyor web engaging ribbing material which will contact the conveyor web and center it with respect to the roller and pulley.

Abstract: A reversible conveyor belt system has, on at least one surface of the belt, projections arranged preferable in a plurality of asymmetrical rows and columns thereby forming a matrix engagable with an offset mating tracking surface glued to the surface of the pulley. The projections are truncated geometrical solids, pyramids, extending outwardly from the surface of the belt. When the truncated solids of the belt intermesh in the tracks provided between the rows of truncated solids on the pulley, positive alignment without creep, improved timing and increased drive force are achieved. The projections may be used on both sides of the belt, and a second belt with interlocking projections may be mounted around a second pulley and positioned beneath the main conveyor belt for heavy impact loads. The drive system includes an easily removable hub assembly wherein the shaft of the pulley defines a flat area which engages a hardened dowel wedge for providing positive drive with reduced shear.
