Adjustment for different size | |
| As you may know, the folding size of the napkin depends on the perimeter of the folding roller. In producing different size of products, we will make this folding unit changeable and offer different parts as per your required size. For instance, 330 folding unit and 300 folding unit,etc.
It takes about 30 min to change this part. |
| The other part to be adjusted is the printing roller. As the width of the raw material is different for different size, we will enlarge the printing rollers to fit for different printing size.
Pls note that, the size must be ordered before production. |
| All of the printing rollers are tightly meshed : 1. The paper will be tightly attached to the rollers and it prevents any stains or color-mixing in printing. 2. This design enables minor adjustment on the pattern position in operation without stopping the machine. |
