Abstract
The invention relates to a pneumatic needling device for the local surface treatment, more particularly fastening, of components, comprising a first and a second needle () that can move in a needle direction; a first and a second piston chamber () for applying pneumatic pressure to the first and second needles in the needle direction; a pressure supply () that can be connected to and disconnected from the piston chambers, more particularly as a result of a movement of the needles in the needling device; a pressure recording means () for measuring pressure fluctuations in the piston chambers; and a control means () designed to carry out a reaction on the basis of the measured pressure fluctuations.
