  • Plate for the spin drum of a centrifuge with spacers and process for its manufacture
    Patent number: 6526794
    Abstract: The invention relates to a plate for a spin drum in a centrifuge. The plates contain integrally formed spacers. These plate spacers are comprised of plate material thickenings and are designed to maintain an intermediate space between two or more plates stacked on top of each other. To create this design, the invention includes a process for the manufacture of the plate as defined above. This process includes the step of roll-pressing a blank over a cone shaped mandrel provided with depressions conforming to the shapes of the spacers of the plate. During this rolling process, the spacers are formed when the depressions in the mandrel are filled with the material of the blank. To ease in the formation of these spacers, the blank may be heated prior to rolling.
