    • A blade holder for cutting machines includes a blade head held on a raising and lowering device and an adjustment mechanism for a circular blade that is held on the blade head. The adjustment mechanism, for the movement of the circular blade between a cutting position and a ready position, is provided with an adjustment piston rod having an adjustment piston that is guided in a chamber of the blade head housing and can be moved by compressed air. The adjustment piston rod is biased by a compression spring into the ready position of the circular blade. The piston surface of the adjustment piston has a cross-sectional area that is configured such that as the path of the adjustment piston in the direction of adjustment increases, the piston surface that is acted upon by compressed air increases.
    • 用于切割机的刀片保持器包括保持在升降装置上的刀片头和用于保持在刀片头上的圆形刀片的​​调节机构。 用于在切割位置和就绪位置之间移动圆形刀片的​​调节机构设置有调节活塞杆,该调节活塞杆具有在叶片头壳体的腔室中被引导并且可以被压缩空气移动的调节活塞。 调节活塞杆被压缩弹簧偏压到圆形刀片的​​就绪位置。 调节活塞的活塞表面具有横截面积,其被构造成使得当调节活塞在调节方向上的路径增加时,被压缩空气作用的活塞表面增加。
