S5: the adhesive surface of the screen protective film tape P1 with the second tab 6 and the third tab 6' attached thereto obtained in S4 is bonded to the release surface of the release film tape with the IR protective film attached thereto obtained in S3 (specifically, by the second nip roller set Y2).
S6: the non-adhesive side of the release-film web GL1, GL2 (specifically from the release-film web feed roller GLR) is pressed against the PE web PE2 (specifically from the PE web feed roller PER2), and the release-film web GL1, GL2 is cut to obtain two release films 5 of the desired shape (specifically by the fourth cutting-roller group Q4) and the release-film web waste GL1 ', GL 2' formed after cutting is wound up (specifically by the waste rollers WR6, WR 7).
S7: the PE mesh tape with the release film attached obtained in S6 was attached to the upper surface of the composite material obtained in S5 (specifically, by the third press roller set Y3), so that the adhesive surface of the release film 5 was adhered to the non-adhesive surface of the screen protective film tape P1.
S8: a strip of PE reticulated film PE2 was wound (specifically, by a waste roll WR8) and a strip of PE protective film PE3 (specifically, from a PE reticulated film supply roll PER3) was applied to the lower surface of the resulting composite material of S7.
S9: and (3) performing shape cutting on the composite material obtained in the step (S8) (specifically, by using a fifth die-cutting roller group Q5), and respectively rolling the cut waste materials, specifically, by using waste material rollers WR9 and WR10, wherein the WR10 is used for rolling PE protective film material belts PE3, and the WR9 is used for rolling screen protective film material belt waste materials P1', so as to obtain a finished product of the mobile phone protective film (specifically, rolling by using a finished product roller CR).
Preferably, the composite material obtained in the step S2 is dedusted by a dedusting film between the steps S2 and S3, so that the product is qualified. The corresponding workstation for the dedusting membrane is not shown in fig. 2, but the dedusting process is well known in the art.
In the invention, because the second ear handle and the third ear handle are directly die-cut and attached on the screen protection film material belt, on one hand, auxiliary materials (PE reticulate pattern film) are saved, the production cost is correspondingly reduced and the production efficiency is improved, on the other hand, equipment required for compounding the ear handles and the PE reticulate pattern film is reduced, the production line is simplified, and the maintenance cost is reduced.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
