Problems with squeegee and floodbar angle adjustment handle on Diamondback S

[Rockers]

This is very annoying as it causes us several misprints when doing larger runs. Generally what happens is that the handle that keeps the floodbar and squeegee locked is becoming loose after, well it could be 50 indexes or sometimes it`s less. The squeegee is then moving freely while printing resulting in shitty deposits of ink. Same happening once in a while to the floodbars too but not as often. I can assure the handle are well tight before we start printing, mist of the times this is happening when doing multi color jobs.

I have had this happen too. Try moving the nobs ( if they are straight up and down put them at a 45° if at 45° already try more 90° ) to get better leverage when tightening. Also to much pressure & starting the print stroke off the pallet I have seen this happen.

Does it correct itself or does it stay loose untill you retighten? Is it the same head every time? Try takening one apart.

Have had similar issues before.  What worked for me was pulling them all the way out (use an allen wrench, pull the handle out, and spin the wrench to pull them quickly) clean the threads (and the threads on the other side of the assembly,) lubricate them, and I bet the problem goes away.

The dirtier and drier they get means your force goes into fighting friction=less clamping force is on the assembly...

First it was only the squeegees, normally head 1, 4, 5, and 8. Now the floodbars are playing tricks on me too. Have to stop the press and retighten almost every job we do that is multicolor. Of course you don`t catch it right away so we normally end up with some rejects.

Is it the angle adjustment levers for the sq/fld bars that are coming loose or is the clamps that hold the sq/fls bars to the horizental bars? Do you have air clamps for the sq/fld bars. From the post description it sounds like it is the  manual angle adjustment levers for the sq/fld bars. ScreenFoo seems to have the order of action.

We have air clamps. The manual angle adjustment lever is causing the problems.

Boy am I glad I don't have to deal with that anymore.. what a PIA that was over the years.
I've broken more of them than you can count on hands/feet and sliced my hand open a couple times when they broke off over the years trying to tighten them enough so they won't loosen up mid-run.

You can replace the crappy plastic control handles with metal ones and or just drop them altogether and just use some bolts and tighten with a wrench.
