Abstract
A belt scraper assembly having a blade holder and a scraper blade disposed therein, wherein a stiffener extending in a longitudinal direction with respect to the belt is provided in the blade body to resist bending of the blade. A scraper blade having a body with a rigid plate member connected thereto and a stiffener disposed in the body of resilient material above a base portion and below a tip portion of the plate member and extending generally transversely with respect to the length of the scraper body. A scraping assembly for a conveyor belt including a non-linearly contoured blade holder and a scraper blade with a stiffener disposed on the plate members between base and tip portions extending generally transversely with respect to the length of the plate including a force-transmitting interface between the stiffener and an inner surface of the rear wall of the blade holder such that the inner surface of the wall offers support to the stiffener to oppose bending of the scraper blade caused by scraping the belt.
