  • Conveyor belt scraper
    Patent number: 6978881
    Abstract: A method of assembling a conveyor belt scraper which includes at least one scraping edge fixed to a support at least by means of a biasing member which includes the steps of prestressing the biasing member in a first sense, maintaining the biasing member prestressed, and mounting the conveyor belt scraper adjacent a surface of the belt whereby, in use, when the scraping edge exerts a scraping action on the belt and is deflected away from the belt, the biasing member is further stressed in the first sense.
