The invention refers to a cutting strip with a cutting edge of highly wear-resistant material, e.g., polycrystalline diamond material, that is laid in solid connection on a base and forms a rail piece together with this base, whereby several rail pieces are laid in series along a holder that is made of wear-resistant material, e.g., hard metal, and has an essentially rectangular cross-section. The holder is provided, along two adjacent edges each with a groove protruding diagonally into the holder, with essentially parallel faces into which the rail pieces are inserted in such a way that the faces of the two grooves reach to the cutting edge of the rail pieces, whereby the faces situated between the two grooves are formed by a clamping piece that can be screwed onto the holder and that collectively clamps against the holder all rail pieces held in the two grooves.

Cutting strip with a cutting edge made of highly wear-resistant material

This invention concerns a device for dehydrating and drying solids, particularly plastics granulated under water in the form of a granulate-water mixture on a curved screen by means of a stream of air that runs both in the direction through the water through the screen and along the screen, with the granulate-water mixture being supplied to the curved screen through a feed duct and being agitated turbulently by the flow energy of the air above the curved screen and being fed to a discharge duct at the end of the curved screen.

Device for dehydrating and drying solids, particularly plastics

A bed knife that acts together with a cutting blade moved past it, particularly for granulating plastic strands, consisting of individual aligned sections of the same type that are fastened to a supporting beam and whose knife edge consists of a cutter material. Each section consists essentially of ceramic cutter material and extends over the areas of feed and delivery of the material to be cut of the cut material. The section is provided with a cutout running in the direction of the bed knife that is aligned with the cutouts of all of the sections and changes into an outer surface of the section as a throat in comparison with the corresponding dimension of the cutout, with the cutouts containing a continuous bar extending through several sections. The bar presses the section against the supporting beam by means of screws passing through the throat that penetrate into the bar, with sections being connected to one another positively by the bar.
