Description

Technical Field [0001] The present invention relates to a sheet-

The present invention relates to an apparatus for producing a sheet product.

Generally, the touch panel is installed on the surface of a display device such as a CRT, LCD, PDP, EL (electroluminescence), etc., so that a user presses an indium tin oxide (ITO) To be able to give. The manufacturing process of the analog type touch panel is generally as follows. A step of laminating a protective film on the back surface of the ITO film on which ITO is formed, a step of cutting the ITO film to a predetermined size, a step of printing an etching resist on the ITO thin film by screen printing, an ITO thin film etching step using an acid solution, Peeling the etching resist, printing the silver electrode serving as a bus bar by a screen method, and bonding the ITO glass. In the conventional method, since all the processes are performed by hand in the above process, a large number of personnel are input, unnecessary consumption of the ITO film is excessively made in order to make a pattern, contamination due to worker's mistake or carelessness during the work process, There were many defects such as breakage. As a result, they are directly connected to productivity, which leads to a decrease in productivity and high manufacturing costs. Moreover, the quality of the product may not be constant because it is a simple method depending on the skill of the user or skill of the user depending on the manual operation.
