Description

Automatic Film Winding Apparatus}

It relates to the take-up device of the present invention, and more specifically, to an automatic film take-up device for automatically winding a film on a take-up roll.

Research and development on the thermoplastic resin film has been carried out a lot so far by many researchers and companies.

In addition, since the thermoplastic resin film is relatively inexpensive as a raw material and has excellent mechanical properties, chemical resistance, transparency, moisture vapor permeability, and the like, the fields used are widely used in packaging, miscellaneous goods, agriculture, industry, food, and medicine.

Recently, many cases of using a thermoplastic resin film in the optical field can be seen. Examples of the thermoplastic resin include polycarbonate, cyclic polyolefin, polyethylene, and polypropylene. In particular, polycarbonate and cyclic polyolefin have relatively good light transmittance, and undrawn products are diffused. It is preferably used for a sheet, a prism sheet, an antireflection film, a retardation film original, or the like.

In the process of winding the produced film, the film is wound on a roll, and when a product is completed, the film is cut and wound on a new roll. In the process of winding the film, the cut part of the film is folded or the tension changes. If there is, a defect may occur in the winding process, so an automatic winding method that minimizes the defect is required.
