ABSTRACT:
A force limiter for limiting the force with which two articles come into contact with each other, which force limiter comprises a control member (11) displaceable with respect to a holder (5), which member is pneumatically prestressed with a force which is substantially independent of the relative position between the holder (5) and the control member (11). The force limiter can be used in devices in which, after stopping a drive the contact force between the driven first article and the second article in contact therewith mustnot exceed a given threshold value. More particularly the use in ultrasonic deformation devices is considered.
