Laminate separation on machines is pretty common especially if they have been stored in a warehouse type location. Its a very easy fix, I use the following type adhesive. Just follow the directions on the can.
Basically you separate the laminate (Gently and careful) then adjust the spray nozzle for the type spray you want, spray both surfaces with adhesive, put something in between the two surfaces while the adhesive is setting, once set ,about 2 minutes, press the two together. Finished. just a note, make sure when you press together that is where you want the pieces to be, because once together, you may not get them apart.
Hope this helps.
