Endless toothed drive belt - of polypropylene for photographic developing appts

摘要

Belt forms part of a conveyor system for a photographic developing appts. and is toothed like a rack along at least one side. Its stiffness is such that the belt run between a driving and a driven pinion describes a path determined by the belt's physical properties and the spatial arrangement of the pulleys; the path is not influenced by the gravitational force on the belt.
