Abstract:
A control system for controlling a needling machine includes at least one needle plate having an array of needles and drive systems. The control system can include a drive tie-rod that can be coupled to one or more of the needles, the at least one needle plate, and a part rigidly connected to the at least one needle plate. The control system can include a cam shaft and a rod, the cam shaft driving the rod in rotation in an axis of rotation, and the rod being connected to the drive tie-rod by a part forming an intermediate lever. The lever can be a single part or a plurality of parts and is able to pivot in relation to a pivot pin.
