The nozzle (4) is adjustable in height in order to select the trimming height, being adaptable to the different rivets existing in the market. It comprises an electrical limit (16, 14) from which, after the mechanical limit has occurred, the retreat of the head of the rivet in order to allow making a new rivet, |
