Abstract
Abstract A conveyor belt made of plastic modules capable of being integrally driven by sprocket wheels. The modules are elongated molded bodies having projections extending integrally from the opposite sides thereof. The projections of adjacent modules are interdigited and connected by rods. The modules are provided with cylindrical driving surfaces in transverse openings therethrough which openings are each aligned with a different projection on one side of the bodies. The combination of projections and driving openings provides a foraminous belt, upon interconnection of the modules, allowing free circulation of gases and liquids through the belt for processing of products carried thereby and for cleaning and sterilization of the belt. The belt may be adapted to traverse a curved path.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
274 words
A module for use in fabricating an integrally driven plastic belt comprising a unitary elongated molded plastic body having: a) a plurality of first equally spaced projections extending integrally from one side of said elongated body, each of said first projections having a generally cylindrical aperture therethrough with its axis extending transversely of said projection, said apertures through said first projections being coaxial with each other, said plurality of first projections being spaced from the ends of said elongated body; b) a plurality of second equally spaced. projections extending integrally from the opposite side of said elongated body in symmetric interdigital location with respect to said plurality of first projections, each of said second projections having an aperture therethrough extending transversely of said second projections, said apertures through said second projections being identical and having rotational axes in coaxial alignment with each other; c) a plurality of openings formed through said elongated body and extending transversely of said coaxial axes of said apertures through said plurality of first projections, each of said plurality of openings being located between a different pair of said plurality of second projections; and d) a plurality of cylindrical driving surfaces each formed in a different one of said plurality of openings at the root of the one of said plurality of first projections associated therewith for engagement with a Claim 1 (continued) sprocket tooth, each one of said plurality of cylindrical driving surfaces having a radius which is about three tenths of the spacing between said axes of said apertures through said plurality of first projections and said rotational axes of said apertures through said plurality of second projections.
Claim 2
Dependent Claim
37 words
