  • Patent number: 9717182
    Abstract: A feederhouse for a combine harvester comprises an endless conveyor having at least two traction means made of inherently flexible material circulating about the deflection rollers and offset from one another in the axial direction of the deflection rollers, between which conveying strips extend. The inner sides of the traction conveying strips are furnished with cams made of inherently flexible material. Anchor plates are embedded in each of the cams. A first fastener having a first head recessed within the individual cam extends through individual cams, through individual anchor plates and through individual conveying strips. The anchor plate comprises two non-circular openings, wherein the first fastener and the second fastener each have non-cylindrical outer circumferential surfaces received within the non-circular openings to inhibit rotation of each of the first fastener and the second fastener relative to the anchor plate.
