Uni I cylinder adjustment

Posted April 21, 2008 by Patrick Masterson   960 views    1 Comment    Print Print   

Hi, folks. I am writing about a damaged Uni I that I have been working on intermittently over the past 10 months. When the press was shipped to me, it was struck and dragged along the right-hand side of the carrriage. Obviously I’ve learned my lesson where crating is concerned but I cannot for the life of me get the cylinder balanced. Recently I had faked, so to speak, an even impresssion by dramatically altering the bearing settings but the press felt awful to print on and I imagine I was creating more problems for my self down the road. At present, I have removed all bearings, eccentrics, etc. and the cylinder is tilted high on the right-hand side and low on the left-hand side. My frame of reference is the smooth inner rail running closest to the press bed. In trip, the left-hand side is making contact with this rail. On my other presses, the proper distance seems to be roughly 1/8″ distance from cylinder to rail when in trip and drops down to make contact when in print. Any feedback would be greatly appreciated. Thank you.
all best,
Patrick Masterson

    Does the “left-hand” side (is that the operator side?) move up and down, just slightly, or not at all?
    Going by memory, I think the cylinder is raised and lowered on hinged arms by a pair of eccentric bearings connected by a cross-rod connected to the vertical gear-rack on the far side. If the cross-rod, or the pin or pin-hole that connect the rod to the eccentric is damaged, then one side won’t move properly.
