The PL-20 is a semi-automatic machine. A hopper and chute system feed the eyelets to the top die of the machine. This greatly increases productivity by allowing the operator to set grommets at a higher rate.The bottom washer can also be placed on the bottom die to create a better hold. Our safety system makes the installation extremely safe for the operator. The safety feature checks for any material, articles or matter that may not be intended to be there by first firing a stainless steel piston that will stop  extending if it comes into contact with something. If the stainless steel extension stops for whatever reason, the main piston will not fire. This safety feature is included on most of our larger machines.
