What size blankets does everyone run on a DGM 430 or Goss Community Unit.

[Steve Bris]

Blanket dimensions we use are 24.69 X 35.

We run Day 9500 3Ply Compressible.

We are having problems with blankets torqing down tight to cylinder. We torque them to 35lbs but you can still feel a bubble underneath blanket unless you take it down a few more turns with a T Handle which you shouldn't have to. Paper packing gets wet pre-maturely because of this I believe.

Anyone else experience this?

Thx

Hello Steve,

First - Don't use Paper Packings, Second - explain the exact procedure in (Steps) how you and the crew

mount the Blankets on the cylinders ?


Regards, Alois

 

[Steve Bris]

Hey Alois, I don't have the time to type out exact procedure and I know we are doing it correctly, this is a new problem.

I was always told not to use paper packing with a compressible blanket.
Been running these presses for 15 years and have never used mylar under the blankets, only under the plates.

mmmm !

mmmm !

Hello Steve,

IF as you say you ARE doing everything correctly - Why are you having a problem ????


Oh, I have some experience of printing on Web Offset Presses from 1965.

Hello Steve,

Thank you, BUT the question you posed - from my reading of the "Q" related to blanket mounting ??

not the size.

Regards, Alois

Basically inch Blanket around cylinder. Start at one end and get each of the 6 bolts started. Once all bolts are started go back to middle and torque down to 35lbs, again starting in middle and working your way out to end. We never crack the torque wrench on the very end bolts, slightly less than others. Then we inch press around approx 15 times with impressions up and re-torque

 

[Steve Bris]

Forgot to add that we torque the blanket again after approx 40k impressions

Ya, has been ongoing for awhile. Ive ordered a slightly shorter blanket to try. 24 5/8" instead of
24 11/16.

 

[Kramer68]

Did you measure a blanket to make sure they cut and barred them to the correct length? I had this happen once to us

 

[Steve Bris]

Yes, one of the first things we checked here.

 

[Kramer68]

So what does your blanket rep think?

 

[Rickyo]

Used to pack to 87 I believe 67 blanket and 20 tho paper .torque middle out all same torque

 

[Rickyo]

Paper packing all I used on web,some guys use to put a strip of grease along blanket edge to prevent water from getting under blanket,I don't no how effect it was but?each to there own I guess

 

[Rickyo]

We’re do you feel bubble curious?

 

[Rickyo]

You check bars on blanket?

 

[Rickyo]
