Abstract: A system which utilizes a scraper blade, set at an angle to longitudinal centerline of a conveyor belt, to remove metal objects therefrom, the belt, under normal operating conditions, being supported in a trough-like configuration. Attached to the backside of the blade is a pair of high density plastic press-down feet. They protrude downwardly a short distance below the lower edge of the scraper blade; and each press-down foot, immediately prior to belt flattening, is disposed above a part of the trough-shaped belt which situated just inside one of its outer edges. Making contact with the belt slightly ahead of the scraper blade, the press-down feet flatten the belt, protecting it as the blade is being lowered. Any contact between the belt and the blade occurs along its lower edge which is covered by a high density rubber guard beneath which the belt can slip. Similarly, beneath the belt are mounted flat, elongated strips made of a high density plastic.
