A belt conveyor is used to feed the paper into the channel, and three sections facilitate the feeding of thin paper. A single alignment system eliminates the need to swap between different sizes and unique geometries. Only the left side should be straight. The grooving section is equipped with 8 high-precision tool holders for easier and more accurate setting. After grooving, the finished product is transported to the front. Waste accumulates on your back.
