Patent ID: 8875870

Claim:
A replaceable conveyor scraping blade comprising: a unitary blade body extending lengthwise along a longitudinal axis and produced from a material having a flexible, elastic quality comprising: a base portion attachable to a tensioning device for biasing the blade body against a conveyor belt; a generally arcuate intermediate portion comprising a first surface extending upwardly relative to the base portion, and a second surface opposite the first surface, also extending upwardly relative to the base portion, and having a scalloped surface when viewed in cross-section taken transverse to the longitudinal axis and extending lengthwise along the longitudinal axis wherein the scalloped surface comprises a plurality of alternating convex and concave sub-surfaces, wherein a scraping surface is formed between the first and second surfaces having a variable contact angle, and wherein the alternating convex and concave surfaces provide a variable contact area which smoothens out peaks and valleys of a mechanical pressure application by providing slight variations in the contact area during blade wear; and a terminal end having a scraping surface separating an uppermost portion of the second surface from an uppermost portion of the first surface.
