ABSTRACT:
Pilot device for a suspended cutting knife of a cutting head of an automatically controlled cutting machine for cutting fabric sheet material spread out on a cutting table in multiple layers. The cutting head is controlled by moving the cutting head along the X- and Y-axes and pivoting about a Z-axis for moving the knife tangently along a predetermined cutting path. 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 of the cutting knife and parallel, at a predetermined distance, to the Z-axis. The support has a slot surrounding the flanks of the knife and a sensor for detecting the instantaneous rotation angle and/or its direction of the support relative to the socket and providing correcting signals.
