Folding Machines

At the in-feed an electrostatic charge is created that will cause the top sheets to stick together. This usually results in a paper jam and consequently a machine stop. Blowing with ionising air nozzles will flutter the top sheets separating them and neutralising the static charge so that they can be removed from the stack individually. Including a static neutralising bar, mounted just ahead of the paper stack, insures that the individual sheets move. Friction generated by the folding operation creates an electrostatic charge again, which will cause registration problems at the folding-pocket resulting in incorrect folds. An anti-static bar will eliminate the static charge, and eliminate folding problems. At the delivery end an anti-static bar will ensure a neat stack.
