Abstract

Abstract An endless conveyor belt (20) is formed of plastic belt modules (23) and capable of following a curved path. The modules (23) include first and second module surfaces, i.e., a top, product-conveying surface and a bottom, sprocket-driven surface. An intermediate section extends across the width of each module (23) transverse to the direction of belt travel. A plurality of snap-on side guards (35) are mounted in vertical openings (38) disposed in the belt modules (23). Each side guard (35) includes a central post (41) having opposed wings (44, 47) extending in a forwardly and a rearwardly direction along the direction of conveyor belt travel. The wings (44, 47) are staggered in the lateral direction so that the forward wing (44, 47) of a first side guard (35) overlaps with the rearward wing (44, 47) of an immediately adjacent second side guard (35).

Claim 5
Dependent Claim 26 words
Side guard (35) according to anyone of Claims 1 to 4, wherein the projection (50) is comprised of a plurality of planar surfaces (80, 83, 86).
Claim 6
Dependent Claim 26 words
Side guard (35) according to Claim 5, wherein at least one of the planar surfaces (80, 83, 86) is substantially perpendicular to the central post (41).
Claim 7
Dependent Claim 28 words
Side guard (35) according to Claim 5 or 6, wherein at least one of the planar surfaces (80, 83, 86) is substantially parallel to the central post (41).
Claim 8
Dependent Claim 95 words
Modular belt system, comprising: a plurality of belt modules (23) having a product conveying surface and an opening (38) disposed substantially perpendicular to the product conveying surface, the module (23) having a recessed portion defined therein adjacent to the opening (38) such that a ledge (53) is formed adjacent to the opening (38); and, a side guard (35) having a central post (41) with a projection (50) disposed thereon, the central post (41) capable of sliding into the opening (38) such that the projection (50) engages with the recessed portion in the belt module (23).
