Roller path

摘要

A roller path has an undercarriage consisting of a profiled plate with lateral recesses and with supports for a plurality of stationary axles which extend approximately parallel to one another; at least two rollers are mounted on each axle. The undercarriage may be manufactured by thermoforming sheet metal, aluminium or semi-finished plastic material and by injection moulding using plastic or plastic reinforced with glass fibre. Both straight and curved sections can be formed from such undercarriages.
