Heidelberg Windmill picks up too many sheets of paper

Hi, I bought a Windmill and it works well except it will sometimes pick up more than one sheet of paper more than I would like. I’m using Crane’s Lettra and have tried using the paper feed adjustments and I’m using only one 22 sucker. It will feed one sheet at a time for about 3 sheets, then it might pick up three at a time, then one sheet for the next 5, then maybe six at one time.

Should I look into different suckers? Or is this just a finicky machine?

You don’t need the rubber suckers for Lettra, the straight metal suction should be fine.

Feeding multiple sheets typically happens when the stack gets too high. Keep it low, use a bit more blast, and more tilt on the sucker bar…

It’s maddening, eh ;-)



i’ve run railroad board without suckers, i’ve never used them on my windmills. Dick G.
