Abstract (en)
[origin: EP0238953A2] 1. A blade head for rotary cutting devices, consisting of a plurality of cutting blades (2, 3) arranged diametrally opposite one another or offset relative to one another in a respective pair, and of support disks (4) mounted between the pairs of cutting blades (2, 3) and capable of being non-rotatably attached to a drive shaft (1), wherein a first bolt (5) projecting at right angles from the blade foot (6) is associated with each cutting blade (2, 3) as a pivot bearing between the cutting blade (2, 3) and the support disk (4), for the purpose of adjusting the radius of the circle of rotation of the cutting blades (2, 3), and a second bolt (7) at a distance from the first bolt (5) engages in a slot (13) on the cutting blade (2, 3) extending along an arc relative to the first bolt (5), and wherein at least two bores (8, 9) for the insertion of the two bolts, each adapted to the distance of the two bolts (5, 7), are provided on each support disk (4) for each cutting blade (2, 3), characterised in that the second bolt (7) is adjustable in the slot (13) extending along an arc relative to the first bolt (5) and is held non-positively and with positive locking in the cutting blade and in that the two bolts (5, 7) project in the same direction from the cutting blade (2, 3) to a support disk (4).
