As shown in fig. 3, the upper and lower circular knife rolls of the third die-cutting mechanism 600 are respectively provided with an upper supporting roll and a lower supporting roll, the hand tearing film and the hand tearing film bear the protective film, the protective film is rolled and die-cut between the circular knife rolls and the upper supporting roll, and the hand tearing film after waste discharge bear the protective film, and the protective film is rolled and attached to the gauze and the double-sided adhesive tape between the circular knife rolls and the lower supporting roll.

The method specifically comprises the following steps:

1. the first release film unwinding roller 1 releases the first release film, the double-sided adhesive unwinding roller 2 releases the double-sided adhesive tape, the double-sided adhesive is attached to the upper portion of the first release film, and is rolled and die-cut by the first die-cutting mechanism 400 to die-cut the outline of the strip-shaped double-sided adhesive reserved area of the gauze product, as shown in fig. 5, the double-sided adhesive in the following figures is cut by the first die-cutting mechanism 400, the reserved area is reserved after waste discharge, and the semi-finished product level at this time is: a fishbone double-sided adhesive tape with the shape as shown in figure 5 and a transparent release film with the functions of fixing position and bearing;

2. the double-sided adhesive release paper winding roller 3 winds the waste material of the double-sided adhesive surface release paper;

3. the waste discharge adhesive tape unwinding roller 4 releases the waste discharge adhesive tape, the waste discharge adhesive tape winding roller 5 winds the waste discharge adhesive tape, and residual release paper waste on the double-sided adhesive tape reserved area of the gauze product is removed;

4. the gauze unreeling roller 6 releases the gauze material belt, attaches the gauze material belt on the upper portion of the double-faced adhesive tape, then passes through the second die cutting mechanism 500 roll-in and die-cutting together, and die-cuts the gauze outline, as shown in fig. 6 and 7, then the gauze waste reeling roller 7 winds the gauze waste material belt, at this moment, uncovers the non-product area of the gauze outer frame, and because the double-faced adhesive is light to the stickiness of the release film, the stickiness is strong to the gauze, the waste adhesive of the outer frame can remain on the peripheral waste material of the gauze. Fig. 9 shows the waste gauze material generated after the product is manufactured, and the waste glue on the back of the gauze is removed when the product is used, otherwise, the waste glue is directly used for the second time, if the waste glue is not aligned, the waste glue is on the back of the gauze and is difficult to be visually confirmed, the finished product has a certain probability of having the phenomenon of two layers of glue, and the waste glue is a defective product which is difficult to identify and can cause the whole roll of the product to be scrapped. In order to solve the problem, the PET film unwinding roller 16 is arranged, the PET film unwinding roller 16 releases the PET film, the PET film is wound into the rubber surface of the gauze waste material belt, then the PET film is torn away, the residual rubber waste on the gauze is removed, the gauze waste is recycled, as shown in figure 10, the gauze with the residual rubber removed is recycled in the original second part, and the high utilization rate of the gauze waste material is achieved by staggering a product distance during lamination, so that the enterprise cost is reduced.

5. The hand tearing film unwinding roller 8 releases the hand tearing film, the hand tearing film bearing protective film unwinding roller 9 releases the hand tearing film bearing protective film, the hand tearing film and the hand tearing film bearing protective film pass through the third die cutting mechanism 600 after being attached by the attaching mechanism 300, and the outline of the hand tearing film is punched and cut, as shown in fig. 8. The hand tearing film waste material winding roller 10 winds the hand tearing film waste material belt, and the hand tearing film bearing protective film after waste discharge and the semi-finished material belt in the step 4 are rolled and attached through the third die cutting mechanism 600;

6. the first release film winding roller 11 winds the first release film with the die cutting tool marks;

7. the second release film unwinding roller 12 releases the second release film, and the second release film is attached to the bottom of the product material belt;

8. the hand tearing film bearing protective film winding roller 13 winds the hand tearing film bearing protective film;

9. the shipment protective film unwinding roller 14 releases the shipment protective film and is attached to the upper surface of the product material belt, and the product winding roller 15 winds the final product.
