Blade head for cutting blades

摘要

A blade head for cutting and planing blades has a blade holder having a plurality of receiving grooves for receiving a cutting and planing blade. The receiving grooves are distributed over the circumference of the blade holder. A plurality of pressurizing elements is positioned in each of the receiving grooves for securing the cutting and planing blade in the receiving groove. At least one adjusting member is positioned in each of the receiving grooves for forcing the pressurizing elements against one another such that the pressurizing elements exert a clamping pressure on the cutting and planing blade. The pressurizing elements have a substantially cylindrical shape with wedge-shaped end faces and a circumferential surface having at least one planar clamping surface. Adjacent ones of the pressurizing elements abut one another with their end faces. The blade holder has clamping counter surfaces cooperating with the planar clamping surfaces of the pressurizing elements.
