ABSTRACT:
In order to be able to position the cutter blades (A, B, C) of a cutter head so that they are radially adjustable in a simple manner in the smallest possible axial space, toothing, (10) is formed in an elongated hole (7) in the area of the blade root (6) at its parallel opposite internal longitudinal edges, whereby toothing (11) at parallel opposite external longitudinal edges of a shaft mounting plate (8) engages with this toothing (10), the shaft mounting plate having a central opening (9), the shape of which corresponds to the cross section of a driven shaft (9'). In this arrangement the thickness of the shaft mounting plate (8) is not greater than the depth of the elongated hole (7), although the length of the shaft mounting plate (8) is smaller than the longitudinal extension of the elongated hole (7).
