ABSTRACT:
Pilot device for a suspended cutting knife of a cutting head of an automatically controlled cutting machine. The cutting head is moved along the X and Y axes and pivots about the Z-axis. The cutting knife is reciprocally movable along the Z-axis. The cutting head includes a device for guiding the unsuspended part of the cutting knife and a pressure foot rigidly connected to the pivotal cutting head. The suspended end of the knife is mounted in the cutting head so as to be freely rotatable around the Z-axis. The guiding device is adjacent to the free end of the knife and comprises a socket rigidly connected to the cutting head having a support which is freely rotatably mounted in the socket around a vertical axis located in front and adjacent to the cutting edge and parallel, at a predetermined distance, to the Z-axis. The support has a slot surrounding the flanks of the knife. The slot is eccentrically positioned relative to the vertical axis and extends to the trailing edge of the knife such that the knife can twist about the vertical axis under the influence of lateral loads that occur during cutting between the sheet material and the flanks of the knife and the bending force of the knife into a balanced equilibrium state.
