Abstract
A blade holder for cutting machines has a blade head secured at a lowering device and a blade head housing having a chamber. The blade head has a blade holding member for receiving a circular blade. An advancing device is mounted in the blade head housing. The advancing device has an advancing piston rod and an advancing piston actuating the advancing piston rod. The advancing piston rod acts on the blade holding member for moving the circular blade between a cutting position and a ready position. The advancing piston is pneumatically actuated and mounted and guided in the chamber. A pressure spring acts on the advancing piston rod to prestress the advancing piston rod into the ready position of the circular blade. A pressing device loads the pressure spring in a direction of the cutting position of the circular blade. The pressing device is decoupled from the advancing piston rod.
