SET FOR MECHANICAL PROCESSING, IN PARTICULAR MILLING SUSPENDED FIBROUS MATERIAL Russian patent published in 2018 - IPC D21D1/30 

FIELD: textile and paper.

SUBSTANCE: invention relates to paper making, and more particularly to cutting parts of machines for milling fibrous materials. Set comprises perforated die plate (2) with openings (12) in a predefined arrangement, into which blade-shaped processing elements (3) which protrude on the process side and are flowed onto by the fibrous material are inserted. Said blade-shaped processing elements (3) in each case have a plurality of base regions (10) which are spaced apart in the longitudinal direction, pass through die plate (2) and project beyond die plate (2) on the side which is remote from the process. In one embodiment, at least some of base regions (10) reach into associated receiving grooves of the base plate on side (14) which is remote from the process. In one alternative embodiment, transverse stiffening elements are provided, which are arranged substantially orthogonally in the longitudinal direction of the processing elements in such a way that the transverse stiffening elements stabilise base regions (10) of the processing elements on the side which is remote from the process.

EFFECT: simplifying the design, increasing the rigidity of blade-shaped processing elements (3), and increasing the flexural strength of joining of blade-shaped processing elements (3).
