Description

[0001] Appartus for molding pattern roll sheet [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding apparatus for forming a pattern on a roll sheet on which a sheet is wound, and more particularly, to a molding apparatus for forming a desired pattern while conveying a sheet wound on a roll sheet, The present invention relates to a pattern forming apparatus for a roll sheet which can be wound in the form of a roll sheet.

In general, a screen provided for identifying various types of information on a portable terminal or an electronic product has a problem of being vulnerable to an external impact. To protect the screen, a display window made of a transparent sheet is attached around the screen. Most transparent windows are used for the display window. Since most of the transparent windows are made of a synthetic resin such as polycarbonate or acrylic resin, scratches or the like easily occur to external impacts due to their relatively low hardness .

The desk-use window sheet is also used as a housing for various electronic products, a key pad of a switch or a portable terminal, and in some cases, a cover sheet for protecting a book cover, and its utilization is remarkably wide.

Accordingly, a fine pattern is formed on one surface of a sheet so as to not only have a beautiful appearance while minimizing scratch marks against an external impact, but also improve the texture of the product. Such a fine pattern has a metallic texture It is common to form fine patterns such as hair fringes such as hair lines that make the appearance of the product look good.

The conventional method of forming a pattern such as a hair line or the like as described above includes a method of directly adhering a thin metal plate to one surface of a sheet or forming a fine scratch using a conventional hair line processor as a surface of a sheet, And a method of thermally fusing the surface of the sheet to the surface of the sheet by using a metal mold having the metal mold formed thereon.

However, in the conventional method of directly bonding the metal thin plate, there is a closed end which can not produce a sheet having high transparency, and a method of forming a scratch and a post-treatment step of treating fine dust generated during the formation of a scratch And when the mold is used, the pattern of the mold is deformed due to a long usage time, resulting in a problem that a desired pattern is not formed properly.

As a result of such a problem, the sheet wound on the roll sheet has been conventionally unwound, and the size of the sheet is reduced to a required length. Thereafter, the protective film attached to one surface of the sheet is removed, A method of forming a hair line by using a known printing technique and attaching a protective film to the surface of the hair line is also used. This is because, in comparison with the above-mentioned conventional methods, The appearance also had a nice advantage.

However, in the conventional method of forming a hair line using a printing technique on one side surface of the sheet, all of the operations are sequentially performed by the manual operation of the operator as described above, And the cost is raised.

In addition, since the sheets in which the hair line is formed are formed one by one, when the hair is to be used, it is cut again into a desired size, resulting in a large loss of the fabric.

In order to solve such a problem, the present applicant has proposed and registered a patent registration No. 10-895756 "Sheet pattern forming apparatus ", which is capable of molding various patterns by easy replacement of a mold, Which is formed by forming a sheet by pressing a resin on a mold plate of a moving jig after a predetermined amount of resin is applied to the mold plate of the moving jig while the at least one moving jig is circulated by the running section, You have to register the molding device.

Thus, in the case of the sheet pattern forming apparatus of the present applicant's patent, the sheet with the hair line formed by the semi-automatic method can be provided. However, in the case of the sheet pattern forming apparatus, The protective film attached to the surface was removed, and then the protective film was adhered to the hairline resin portion after the compression molding.

Accordingly, as described above, the size of the sheet from the roll sheet is cut, and the troublesome problem of peeling and attaching the respective protective films on the cut sheets of several sheets can not be solved.
