The invention relates to a clip machine comprising two closing tools that are movable relative to each other between an open position and a closed position in order to close clips, and further comprising adjusting means designed to set the neutral position of a closing tool and hence the gap between the closing tools, in particular in their closed position (closure gap). The clip machine includes a measuring device configured to measure a closing force applied when closing a clip, or a parameter proportional to said closing force, and to output a measured value representing the closing force or the parameter proportional thereto. The invention also relates to a method for adjusting such a clip machine.
