vinyl buckling at end of laminator run…
Curious to know if anyone else has had this issue…
We’ve got a GMP 1300 cold laminator and in the winter and cooler temperatures it seems to run without any real hassles, but when the weather gets hot we seem to have issues.
Cooler times of year we can run a lot through this laminator in one hit, probably do 20 metres quite easily. When the weather gets hot we have this issue where the start of the run is okay but by the time we get to the end of say, a 4 metre run or longer, the vinyl print appears to be buckling as it feeds in to the rollers. Obviously that leads to a creased print.
When the temperatures go down again it all goes back to normal. It’s been a bit cooler recently but last couple of days have been higher temps and I’m seeing it again!
Anyone else seen this or cured the problem?

There have been some very long threads about this subject, although I’ve not looked for them.
I think you may have a bit too much pressure on the rollers. -
The heat may cause the roller size to expand enough to cause the pressure to be too high as Steve said.

I have a very basic cold laminater, and it’s possible to get the effect you describe at any time of the year, small adjustments to the pressure usually cure it. Experimenting is going to be the only way to resolve it I think

Thanks guys,
We’ve had the laminator 6 years and tried all the various tension tweaks. We have to have the tension fairly high on the feed roll because if it’s lower, the laminate doesn’t go down flat on to the print.
The real point though is that when it’s colder time of year it’s perfectly fine again.
If the warmer temps are causing tension problems with the rollers, I’m up the creek because I can’t slacken off the tension anymore.Manufacturers have said you should always release the rollers when not in use, we’ve never done that actually, they reckon it will wear the rollers – but only in the summer?!!
Scratching my head over this one!
