Edgebander glueline failure8/10
I can not get my laminate or wood edges to adhere to my panels. I can turn the glue up, but can still pull off edge with nothing sticking to edge and all glue remaining on panel. Doesn't matter if pb, mdf, etc. the edge does not stick. I have no problems with pvc of any kind. We are using Jowat 288.60 that we have been using for seven years. Did not have any problems until we changed out our glue pot on our Brandt edgebander two months ago. Had the Jowat rep in to test heat and take a sample and said all was okay, but told us to use a primer. Now if I have to spend the time putting primer on my laminate why would I not just spray it up and put them on by hand? What do I do about my wood edges? Help any one?
We had an external air supply to blow chips away and had the same problem. I removed the air supply and the problem fixed it self. I would guess the glue is cooling to quick. Also pull the roller away alittle to get more glue on without opening the glue throat. Just an idea.
If you dont prime your laminate, your asking for serious trouble in my book.
Brian, ditto what Mike said about priming.
Why not put them on by hand you ask, spend 2 to 3 minutes spraying a 4 x 8 sheet of lam. with primer, then apply all of that thru the bander as normal. Then time yourself spraying, sticking, rolling, trimming, etc, the same amt. of banding.
Obviously the bander is still a no brainer on time.
Have a problem with laminate edges sticking together after priming. The edge tray sits right behind the glue pot and it must activate the primer cause they dont want to feed. Mixing Jowat primer with 50% water and using spray bottle, edges sit for a day before use so I know they're completely dry. ????????????
We have always had the same problem since we started priming plam many years ago.
Never been able to put a stack of strips behind the feeder without them sticking, we insert 1 strip at a time.
This is why we charge more for colors that do not have a pvc edgeband match.
We also prime all HPL before edging, the bond is much better and never had any delam issues when priming had several before we started priming.
We use the dorus primer which is a very easy to spray on and dose not stick to each other when dry.
We do have trouble with our HolzHer bander feeding multiple strips (not because of the primer though) but have no issues with our SCM feeding stacks of strips that are primed.
We have used Dorus primer for a long time with no problems. Spray full sheets of laminate or just a quarter of a sheet it dries pretty fast and no sticking problems. We also use it on solid wood banding. In both cases you get a lot better hold. Get one of those infrared thermometers and read you glue roller temp. They cost less than $100 and are worth knowing you are right on target. You can also use them to tell when a heater has failed or when a bearing is running too hot.
