Abstract: A finger roller for agricultural machines is provided. At least one finger disk is disposed on a shaft of the finger roller and has a hub, over the periphery of which are distributed and project a plurality of fingers. The fingers are at least slightly elastically deformable, and a side of each finger that faces in the direction of rotation of the finger roller is markedly roughened, for example by being provided with fine ribs, studs or knobs.

Abstract: A finger roller for an agricultural implement has a shaft with a non-circular cross-section. Two or more finger disks are pushed onto the shaft in the axial direction of the shaft. The finger disks each have a hub with a central opening having an inner contour configured to match the cross-section of the shaft. The finger disks each have elastically deformable fingers connected to the hub. The fingers of each one of the finger disks are distributed uniformly about a circumference of the hub and project away from the hub. The shaft has a circumferential surface comprised of identical circumferential portions sequentially arranged in the circumferential direction of the shaft. The finger disks each have an odd number of fingers when the circumferential portions are even numbered, and the fingers disks each have an even number of fingers when the circumferential portions are odd numbered.

Abstract: An endless conveyor for conveying tuberous agricultural products has at least two parallel and spaced apart, pull-resistant, flexible belts, extending in the conveying direction of the conveyor. Spaced apart and parallel followers extend perpendicularly to the conveying direction. The followers are connected to the at least two belts. A web is provided that has portions extending between the followers for supporting the tuberous agricultural products. The web has flexible web elements extending angularly to one another and having crossing points. The web elements are connected fixedly to another at the crossing points.

Abstract: An elastomeric stator for an eccentric spiral pump is provided. The stator has a lining that is made of elastomeric material and has a hollow chamber that serves for accommodating a rotor. The hollow chamber has a double or multiple spiral configuration. A rigid casing surrounds the lining and both the casing and the lining have an essentially uniform thickness over their length. The casing is spiraled in conformity with an inner contour of the hollow chamber. A respective flange ring is secured at each end of the casing for resting against other pump parts. The flange rings are detachably connected to other pump parts without the use of tie rods.

Abstract: An endless conveyor for conveying tuberous agricultural products has at least two parallel and spaced-apart, pull-resistant, flexible belts extending in the conveying direction of the conveyor. Spaced-apart and parallel followers extend perpendicularly to the conveying direction. The followers are connected to the belts and have projections arranged in the transverse direction perpendicular to the conveying direction. A web having portions extending between the followers for supporting the tuberous agricultural products is provided. The web has flexible, pull-resistant, elongate web elements extending angularly to one another and having crossing points. The web elements are connected fixedly to one another at the crossing points and define mesh openings. The mesh openings in the area of the followers are penetrated by the projections.

Abstract: The method of producing an elastomeric stator, and a stator produced by such method are provided. On its outside, the stator has a metallic spiral body, the shape of which corresponds to that of a hollow pump chamber. Elastomeric material is injected into a mold that contains the spiral body in order to form an elastomeric lining of the body. The elastomeric materials are introduced into the mold in such a way that the outer surface of the elastomeric lining merely rests against the spiral body and is not bonded or otherwise fixedly connected thereto.

Abstract: An endless conveyor for conveying tuberous agricultural products has at least two parallel and spaced apart, pull-resistant, flexible belts circulating in the conveying direction of the conveyor and followers distributed over the entire length of the endless conveyor. The followers are arranged transversely to the conveying direction and project from the conveying plane of the endless conveyor. The followers have rigid rods with end portions connected to the belts. The followers have posts extending to essentially a projecting height of the followers. The followers have a flexible strip essentially extending between the at least two belts. The flexible strip consists of a web and has ends connected to the posts.
