Working Principle
（1） Firstly starting the machine, the second clamping device move the material to the right position and cut one time. Then the main material unwinder pass through the tension structure and separate to two sheets.
（2）After that, it goes into the recycle. When the main material is at the right position, Panasonic servo motor takes the bottom material to the target position. At the same time, bottom material enters and press.
（3）After pressing, the bottom film is sealed with main film. And then, servo motor controls to return. After sealing, the sealing motor returns and the bottom film feeding motor finishes. The second cutting cut the bottom film and returns. After all above actions, one cycle action finishes.
