Abstract

Official abstract text for this publication.

A treatment element to treat material in a multi-shaft worm machine has an outer contour with at least one outer contour portion, the associated evolute of which is a quantity of at least three points, each of the points lying outside the longitudinal axis and within the outer radius of the treatment element and two respective adjacent points having a spacing from one another, which is less than half the core radius. The treatment element ensures high flexibility during the adjustment of shear and/or extensional flows on the material to be treated.

First claim

Opening claim text (preview).

The invention claimed is: 1. A treatment element for treating material in a multi-shaft worm machine, comprising a longitudinal axis M, a respective core radius R i having the longitudinal axis M as the centre point and an outer radius R a , an outer contour A(φ) running about the longitudinal axis M, wherein φ is the angle about the longitudinal axis M and R i ≦D A (φ)≦R a applies to a spacing D A (φ) of the outer contour A(φ) from the longitudinal axis M, wherein…
