The device is a pouch laminator. During lamination, so the film is heated. The unit needs a few minutes to warm up (and stinks here first). As long as it is still too cold for laminating, lit a red lamp. Is it ready for operation, the red light will switch to blue. There is a starter pack included, which are 20 sheets A4 and 10 each in A5, A6 and business card size in order to weld such as identity cards of paper card size can, or business cards that you want to protect. Further, heat activated laminates one gets easily in the office products industry. Each slide consists of two adjacent folded sheets that on the other three sides are connected to one side and open. So you can then sandwiching the paper to be laminated. In other words, one A4 sheet is therefore an A3 sheet which has been folded. Furthermore, a thin A5 booklet comes with, where in several languages, a Quick Start Guide is included (namely 3 pages per language). The essence is in it but. Permitted film thicknesses are 80-100 microns and a maximum of A4 Lamination is about 230 mm / min The recommended maximum document thickness of 0.6 mm should not be exceeded, as otherwise stuck the document. In addition, always pay attention on it that at least 3 mm around the laminated paper to remain only the laminate film subject, otherwise the two films that coat the paper, can not connect. The 0.6mm are mE meant außenrum to be laminated paper along with the film. When in doubt, I have measured the total thickness with a caliper. I had read but trust no experience with lamination, you will quickly with the operation. It has proven to be practical, first everything is to be laminated, to make ready beforehand on the table, so you when the unit is hot, everything can be laminated successively. Since the insertion hole ca is 2 cm above the table level, I put an A4 board or book in front and behind the unit in about 1 cm safe distance, otherwise the be laminated is in the front or the back, where it comes out from the machine down. This can result when still hot to be laminated Donauwellen in the lamination. Can it behind the unit flat land on a same high surface, this does not happen and that can be laminated just lie there and let cool briefly. Is it open to attack, the films have good enough joined together at the edges and no longer goes on and remains wrinkle-free. Is also a board or book in front of the machine, one avoids by not only the slippage of Laminiergutes in the films (for example if I simultaneously laminiere bookmarks or more small things in an A4-sheet and afterwards apart cut (but since then has at least 1 cm remain between the individual Laminierobjekten, otherwise keep the films after Auseiandernscheniden not permanently together). Gently and slowly forward to introduce the laminating film to be laminated together in the slot is recommended, otherwise it tilts and is wrong. If you pay attention, this does not happen. Would have been helpful if the slot would have been colored frame, because the unit is side black and the slot as well, so do not just simply particularly in artificial light. If one has the right to be laminated and placed slowly and carefully inserted into the slot, the device detects the be laminated and transported it on itself slowly.
