Document Type and Number:
WIPO Patent Application WO/2024/009844
Kind Code:
A1
Abstract:
This metallized film manufacturing device comprises: a supply unit that supplies a dielectric film in a lengthwise direction; a printing roll that has a rotational axis in the width direction of the dielectric film, and that prints an insulation pattern on a surface of the dielectric film; and a deposition unit that forms a metal deposition electrode at positions, except where the insulation pattern is, on the surface of the dielectric film. The printing roll has protrusions that are formed axially extending on the outer circumferential surface of the printing roll, and that correspond to the insulation pattern. A reinforcing part is formed at one end of each protrusion in the axial direction of the protrusion.
