Details that make a difference

The single roller glue unit with doctor blade and side dams allows the operator to put the glue only where it is needed. This small area of glue will not dry out in production. Clean-up is very quick. The glue unit slides out on tracks. Glue pads are made off line on a make ready table. Stereo mounting the foil is used to mount glue pads on and then the foil clips onto the stereo cylinder.
These stereo blankets can be saved for future jobs.
