  • Patent number: 5738223
    Abstract: A screen conveyor belt for farming equipment has a plurality of flat belt members having a longitudinal extension in the direction of travel of the screen conveyor belt and being arranged parallel to one another. Rod members extend perpendicular to the direction of travel and are spaced from one another in the direction of travel so as to form therebetween openings of the screen conveyor belt. The rod members have a first and a second flat end section and a central operative portion located between the first and second flat end sections. The first and second flat end sections of each one of the rod members are positioned on adjacent ones of the belt members, respectively. Fasteners for connecting the flat end sections to the flat belt members are provided and the fasteners penetrate the flat end sections. A thickness of the flat end sections is greater adjacent to the central operative portion than at the free end of the flat end sections.

  • Patent number: 5692598
    Abstract: A conveyor belt for a conveying device has pull-resistant, flexible belt loops extending in a direction of movement of the conveyor belt. Rods having opposed, flat ends are provided with bores. The rods extend perpendicularly to the belt loops and rest with the opposed flat ends on the belt loops. Fasteners for securing the flat ends to the belt loops by penetrating the bores of the flat ends and the belt loops are provided. The flat ends have a leading edge and a following edge in the direction of movement. The leading and the following edges have rounded projections in the area of the bores.

  • Patent number: 4892509
    Abstract: A belt with rods for a rod belt conveyor. Transversely extending rods are secured to the side bands. In order not to have to further prepare the rods and the bands, yet to provide a secure connection, a holder extends about the rod ends, with the ends of the holder being held by clamps that are forced into the non-prepared bands. The clamps or securing elements could at the same time also be formed as holders and could thereby form the aforementioned holder.
