Electrostatic discharge of printed products before the three-knife trimmer

What is the task of a three-knife trimmer?

Adhesive-bound print products fall via a conveyor belt into a collecting chute where they form a stack. From there, the copies are fed to a three-knife trimmer which trims the print products at three edges.

Electrostatic charged papers adhere together

Electrostatic charging of the printed products delivers a varying number of copies to the three-knife trimmer. Sometimes all the products stick together, which stops the production process.

Our solution

The solution is to electrostatically discharge the printed products at a suitable position before they are cut by the three-knife trimmer.
