Electrostatic discharge on a gathering machine

How does the gathering machine work?

Gathering machines are used to gather individual sheets in the desired arrangement. Machines with up to 30 stations are built. A gripper arm with suction nubs takes the single sheet from the top and places it on the transport chain. The stacks are fanned out from the front with compressed air using an aluminum perforated bar to prevent sticking, so that multiple sheets are not taken out. This works quite well with paper, with films there are problems due to higher electrostatic charge!

It comes to electrostatic charges of the foil sheets

When gathering films, the conventional compressed air bar is not sufficient to separate the films. Stops occur again and again because the film either sticks to the stack or several films are taken out. The many stops result in excessively high production costs. Some print shops reject such jobs.

Our solution

Special ionizing blast nozzles can be used to reduce the charges between the plastic films. It is mostly necessary to use a power supply unit with optimized ion balance.
