A machine for automatically applying snap fasteners on a support, such as a fabric, comprises a sensor for sensing the instantaneous value of the riveting pressure applied to the machine punch elements. <??>With respect to prior machines for automatically applying snap fasteners, the machine according to the invention provides the advantage that the snap fastener can be applied to a fabric with a proper riveting pressure, so as to prevent both excessive pressures, which could damage the fabric, and insufficient pressures, which could not provide a proper connection of the snap fastener on the support, from being generated. <IMAGE> |
