Latest Patents

One of his latest patents is a method of finishing screen plates. This invention involves a screen plate and a method for making it, specifically designed for the pressure screening of papermaking stock. The screen plate features slots that are cut through by a machining laser beam, which is focused at the inlet side of the plate. This technique results in slots with nearly straight walls and minimal taper. The walls have a 'glassy' appearance due to the melting and resolidification of the immediate surface, providing a low friction path for the stock. The design includes straight, curved, and inclined slots, as well as slots that are diagonal to the axis of the cylinder. Additionally, wear bars made of high hardness weld material are applied to the plate to work in conjunction with the rotating foils on the screening apparatus.

Another patent by Landegger also focuses on the screen plate and its manufacturing method, reiterating the importance of precision in the design of slots for optimal performance in papermaking.
