Edgebander glue issues10/10/19
I'm running a Biesse Lato 23S and I am getting on some of the pieces run what looks like a dry lump of glue under the banding. Wondering if anyone knows what is causing this?
I don't have an answer, but I've been meaning to post the same question. I have a brand new scm bander doing the same.
Not sure, but I've read somewhere that edgebanding glue has not so long shelf life and that it deteriorates quickly once the air gets into storage container.
We keep ours in a container with a lid after opening
We got this on occasion over the years.
We have the same issue sometimes on our Brandt. The cause of ours was we were applying to much glue. As the part was coming off the glue roller it was leaving "strings" behind. While there is a rod that is supposed to pull the strings off and push them back into the pot, it wast doing so. The strings would stick and build up on a different section of the machine and let go once they got to big. You might also want to check that the edge isnt dragging on anything after the glue is applied and leaving build up somewhere to fall off.
I will adjust the glue roller and see what that does. I hate messing with it as it is really touchy on this bander. I am running Jawat 288.70 and I am running at 200 degrees on the roller and 190 degrees on the pot.
After looking really close I found that the material was in fact dragging on the unit that holds the tape in place just before the pressure roller. When changing tape that gets adjusted and it was out of the slot.
-Thanks for all the help
Nathan W is spot-on correct about the Brandt, we have one too. Fantastic machine, but if we have the glue temp too high or too low, it tends to develop a lot more of the "cheese pizza strings" as the glue comes off the roller onto the material face.
At the first sign of string buildup, we start dropping glue temp by about 5 degrees, or increasing glue temp, depending on the ambient temp. Winter=hotter glue, summer=colder glue.
What glue manufacture are you using? We use a Visual zero joints with PUR glue - HOLZ-HER and haven't had any issues yet. I hope this helps..
