  • Scraper unit for an endless belt
    Patent number: 4529084
    Abstract: The invention has to do with a system of elements for keeping a scraper blade in position under an endless conveyor belt, the system being made up of a support, a spring joint and a cross piece running across and under the belt. There is an element bracket so that the unit made up of these parts may be rocked about an axis running in the length direction of the belt. In this way it is possible to put every scraper edge on a blade into a position in which it is truly parallel to the lower face of the endless belt in very simple way.
