Abstract

1379097 Dredger cutter heads VAN HATTUM EM BLANKEVOORT BV 7 Feb 1972 [11 Feb 1971] 5677/72 Heading E1F A rotatable cutter head for use in a cutter dredger has secured to helical arms 2a, which converge together at one end of the head to form a hub 3 and, at the other end, are interconnected by a support ring 4, cutter teeth 5 that so extend laterally of the arms that the axis of each tooth crown lies in a plane that is defined by a perpendicular to a surface of revolution centred on the axis of the head and enveloping the cutting tips or the middle points of the cutting tips at the point where the tip or the middle point of the cutting edge contacts the surface and the tangent at said point to the orbit of said point when the head is rotated.
