Abstract: An automatic grommeting machine for high speed, large volume insertion and setting of eyelets, grommets, etc., and their mating washers, without requiring pre-punching of a hole. Dual cams are connected to a series of linkages which control the movement of a top set, a bottom set and a clamper, as well as controlling the withdrawal and insertion of grommet and washer roadway slides in synchrony with the top and bottom sets. The grommeting machine is fully automatic, i.e., the operator simply inserts a piece of material into the machine and activates the machine by pressing a single pedal to insert and set a grommet or eyelet and its corresponding washer in the material.
