Tim, I used my conturo for the first time yesterday running laminate edge banding. I had the same hang up as you describe on maybe 3 or 4 pieces out of about 20. The excess glue on the roller seem to fall off easy once it cooled. The glob on the surface cause no problem as it was on p-lam. I could find no reason for the random piece to not feed just like normal and I hope someone can offer a tip to eliminate this altogether. I will say I love the machine and should have gotten it when it first became available.
