Embodiment Construction

[0037] Next, the best mode for carrying out the present invention will be described with reference to the drawings.

[0038] figure 1 A film winding device 10 according to an embodiment of the present invention is shown. This winding device 10 includes a supply unit 12 that feeds out a strip-shaped film 11 wound around a bobbin or bobbin (not shown). The supply part 12 in this embodiment refers to an unwinding shaft configured to be able to install the metallized film 11 wound on a bobbin or bobbin not shown in the figure. The metallized film 11 is formed in a group of two, superimposed in pairs and then wound. Therefore, the unwinding shaft 12 as the supply part also has a pair, that is, two, so that two groups of strip-shaped metallized films 11 can be installed respectively. Here, as the metallized film 11 , a film having a width of 80 mm and a thickness of 3 μm formed by forming a metal vapor-deposition electrode on one side of a dielectric film made of polypropylene is ...

Abstract

The invention provides a film gauffer removing device, a film tension adjusting method and a film gauffer removing method, wherein a film is given a proper tension and gauffers generated in the width direction of the film are eliminated, while the winding speed of the film is increased.The film gauffer removing device (30) comprises a first component (31), a second component(32) and an air injection unit.The first component (31) is used for the extension of a tape-like film (11) moving in a length direction or the winding of the tape-like film.The second component (32) is used for clamping the film (11) together with the first component, thereby forming an air hole (32b) facing the film (11).The air injection unit injects air to the tape-like film through the air hole to push the film to the first component.The film take-up device comprises the above film gauffer removing device (30), a supply component (12) for providing the winded film, a winding component (13) for winding the film provided by the supply component and a plurality of transport rollers arranged on the conveying path between the supply component and the winding component.

Description

technical field [0001] The present invention relates to a thin film wrinkle removing device and the like which can be used in the manufacture of various electronic equipment, electric equipment, industrial equipment, automobiles, etc., and capacitors and batteries using thin films. More specifically, it relates to a film dewrinkle device and a film tensioner that can be used in the manufacture of smoothing, filters, metallized film capacitors for shock absorbers, etc., which are most suitable for inverter circuits for driving electric motors in hybrid vehicles. Adjustment method, film dewrinkling method and film winding device. Background technique [0002] In recent years, from the standpoint of environmental protection, all electrical equipment is controlled by inverter circuits, and energy saving and high efficiency have been continuously improved. Among them, especially in the automotive industry, the development of technologies related to environmental protection, ener...
