Views and opinions on the RollsRoller Application table?
Must be a few of you on here have used or own and use one.
Do you ever have issues with the vinyl you are backing up, creasing?
If its a long piece of media, i will often ask someone to hold the end tight while i roll tape across it, but recently even the little pieces of media are giving us issues.
Initially i thought it could be down to temperature, so installed a heater at the end of the bench to keep the tape warm.
The pressure was set at 4psi and has recently been increased to 5psi with hopes that it would ease the crease out before it starts.
What pressures are you all using and any tips/ tricks? -

We have the 5.5m bed RollsRoller…
Pressure wise, I think we run it about 2.5 – 3.0as long as you have the media hanging over the foam roller, its own weight should keep it taught enough to use at a steady moderate rate. if you go fast and slow up then of course gravity kicks in and the media will slide forward creating a crease but to prevent this "but still keeping a steady rolling motion" just let your finger tips of your free hand gently drag over the tacky side of the vinyl and it will prevent any slack happening.
once you have side one down, hold the roller to where you just feel the bite/ridge of the folded paper below it and then begin. this prohibiting a fold or crease at this stage.
a cold workshop and flood coating cool aluminium sheets can have adverse effect on the media with regards to a sort of wave or puckering of media which i guess can also lead to creases etc. a heater will help this but keep in mind the metal substrate the media is lying on will be colder than the air in the workshop.
the above is NOT a negative of the Rollsroller, it is exactly the same as any other vinyl mounting table. just takes a few goes to get the knack of it. but if things like workshop heat etc come into play then you may need to be a bit more cautious.

Thanks for that Robert, i think ours is the 5.5m although never measured it. No idea of the foam roller though? We just have the black rubber roller that comes down onto the table. Media is just placed flat on the rubber mat and then the roller runs over it.
-
Yes the black roller is what i mean. guess it "could be rubber" but thought it more a very tight dense compressed foam, but did not think it’s solid rubber like a laminator roller. same part though regardless. :smiles:
-
The only time we’ve had this is when it board is not placed in the middle of the Rollsroller creating uneven pressure we apply most boards at 4psi and correx at 2psi. Does your roller need adjusting?
-
Most of the media we deal with takes up most of the bed and often comes right to the end. Im starting to think we have some sort of indent in the middle of the mat. I have tried several different pressures and still no gain.
I will have a play -
When you raise and lower the roller does one side move faster or slower than the other side? there is adjustment to correct this.
-
Hi Chris
Don’t forget the Rolls Roller is sold with a 5 year parts and labour warranty. A quick call to your suppliers should help identify if the roller needs adjusting or if further investigation is needed.
-
Further to this topic… today was a prime example of whats happening. See picture below.
First half goes down fine, as it passes midway the media starts to crease and ends up being a pain to fit.

Random question, is it metamark vinyl you are using? We had something along the same lines before and i was determined it was our machine (not a RR), had lots of trial and error and eventually realised that for some reason some metamark vinyls would create this problem but oracle and 3m are completely fine. Its almost as if the backing on the metamark liner is slippy and causes it to bunch where as the other brands are more paper feeling.
We discovered the reason when laminating a 2x1m Air release print which bunched terribly, tried again and same result. switched to a 3651 air release and no problem, switched our cut vinyls the next day and never had a problem.

This has actually been in my mind, along with the orientation of the weeded media on the backing.
This was hexis material i think, but we use a range. Hexis, metamark, avery and so on.
We tend to stick to certain makes for colours, hexis being black and white. But this happens 75% of the time. Only way to really stop it is to put a relief cut in it and the just allow the roller to roll over it. -
Yes we have the same issue and it’s the liner on the Metamark M7 vinyl that causes this. Metamark know about the liner problem and are apparently working on a solution but can’t say when that will happen. I can only guess it’s a small market having this problem so they won’t be in any hurry to change it.
-
I don’t know about the Metamark issue creating this but anytime this sort of thing has happened to us, was down to the room it was in being too cold. The media would have a sort of light wave in it and then when you applied application tape which was going down tight and flat, it exaggerated the wave as it moved along the table and by the end the wave was pinned down by the tape causing the creases. I later moved our RollsRoller into our print room and have never had a problem since.
I am merely pointing this out as its good to know options of what it "could" be, i.e. Room Temp but then again could be the liner as has been mentioned.
-
Well its nice to see others have had this issue too!
Our room is pretty cold. The building is 100+ years old and used to be a butchery haha, although we do have a pretty good heater and 2 infared heaters pointed at the table, i don think this is quite enough. -
we used to have similar heating issues because the buildings we are in couldn’t have central heating and we tried everything.. the problem with IR heaters, space heaters etc etc is they do work to an extent, but its not warming the room and all in it keeping at a constant heat.
Many people store their media on end, but the cold stone floor or whatever keeps one half of your media cold, even damp to an extent at that one side. even those on plastic base plates because they are only an inch or so from the cold concrete and the other end is nice and dry. this is all the way to the core, so stick it up on the mounting tables and try applying application tape to it and you will get inconsistent and poor results.
-
Just to confirm for my experience and what Rob has mentioned, our vinyl is horizontal on racks off the ground and also we are always in a nice warm environment. Metamark have told me they know about the issue so on the M7 it’s a liner issue. The vinyl is great and normally no issues but when on the table it can be.
We were applying 8×4 sheets on to ACM boards to flood coat them so no application tape either.
Rob’s comments are also 100% correct but not always only those reasons 😉 lol
Cheers

Cough cough splutter bullsh*** [FACE WITH TEARS OF JOY][FACE WITH TEARS OF JOY] pmsl
You are correct of course warren and much better to have several possibilities to consider till resolved -
Interesting Warren… We run M7 through our Easymount to tape up long runs of cut vinyl, and find it ‘puckers’ in the middle of the roller, I’m going to try some 551 we have in tomorrow to see if it happens with that. We’ve tried less pressure & tension etc.
-
Just a follow up to this…
If anyone is still having the issue i think we’ve solved it.
Pop to the local boots,tesco,morrisons etc and get some talcum powder.
Spread a thin layer over the mate and rub in with a cloth.
If you have a air compressor, blow the remainder off and then finally wipe with a dry cloth.
It seems to create an almost air hockey table type feeling and no more creases!
