You English is not clear, but there should always be something for the laminate to stick to. Either the work you want to laminate, or something like craft paper you put through that is big enough to take up any overhang. With mine, if the laminate is slightly bigger than the work, or the laminate starts to track poorly causing it to overhang the artwork slightly it is OK. If too much of the adhesive side is exposed it can stick to the rollers and ruin everything. I use pieces of backer to start the laminate.
