S22, after the third support film strip is laminated below the waste material strip peeled off in S2, it is die-cut by the fifth circular die-cutting roller group. The cutter rollers of the fifth circular die-cutting roller group enter from above, cutting through the protective film strip and the second set of handle release film semi-finished products, forming the outline of the second set of product main material, the outline of the second set of protective film layer, and the outline of the second set of product handle release film. The outline of the second set of protective film layer also includes the protruding handle part outline, which coincides with the outline of the second set of product handle release film. At the same time, two sets of pierced protective film strips are formed and the fifth positioning mark line corresponds to the other set of first positioning mark lines. Then, the waste material of the first transition film within the outline of the main material of the second group of products, the waste material of the protective film strip outside the outline of the release film of the handle of the second group of products, and the waste material of the main material within the outline of the release film of the handle of the second group of products are excluded. At this time, from bottom to top, the following are: the third bottom film strip, the second protective film layer, the second single-sided adhesive layer, the second foam layer, and the second double-sided adhesive layer. The handle part of the second protective film layer has the release film of the handle of the second group of products. S221, separately composite the fourth bottom film strip and the second release film strip, and perform die cutting through the sixth circular die-cutting roller group. The outline of the second release film layer is cut out from the top and the waste material outside the outline of the second release film layer is removed, forming the second release film layer on the fourth bottom film strip. After being flipped by the second flipping roller, the second release film layer is aligned and laminated with the second double-sided adhesive layer on the second product main material strip. Then, the upper fourth bottom film strip is removed, and finally, after being cut by the seventh circular die-cutting roller group, the bottom third bottom protective film is removed, resulting in the finished product of the second set of die-cut components with handles.

3. The manufacturing process of the material-saving die-cutting assembly with handle according to claim 2, characterized in that: The first circular die-cutting roller group has a closed handle portion first contour line blade corresponding to the first contour line of the two sets of handle portions and a first positioning mark line blade corresponding to the first positioning mark line; and the two sets of closed handle portion first contour line blades are centrally symmetrically distributed.

4. The production process of the material-saving die-cutting assembly with handle according to claim 2, characterized in that: The second circular die-cutting roller group has a protective film contour line blade corresponding to the shape of the protective film layer and a second positioning mark line blade corresponding to the second positioning mark line. In addition, the protective film contour line blade is provided at the forming handle part with a main material end line blade for cutting the main material end. The blade height of the main material end line blade is smaller than that of the protective film contour line blade. The blades on the fifth circular die-cutting roller group are arranged symmetrically with the blades on the second circular die-cutting roller group.

5. The manufacturing process of the material-saving die-cutting assembly with handle according to claim 2, characterized in that: The third circular die-cutting roller group has a release film contour line blade corresponding to the shape of the release film layer and a third positioning mark line blade corresponding to the third positioning mark line; the blades of the sixth circular die-cutting roller group are arranged symmetrically with the blades on the third circular die-cutting roller group.
