Embodiment Construction

[0042] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 to Figure 3 The structure of the coating part of the double-sided coating apparatus which concerns on 1st Embodiment of this invention is shown. The double-sided coating device of this embodiment conveys the web material W in the arrow A direction. In addition, the double-sided coating device has: a first finishing head (coating die) 1 that applies the paint P as two lines on the first side (back side) of the fabric material W shape; supporting roller 2, which supports the second surface of the fabric material W at a position opposite to the first coating head 1; the second coating head (coating die head) 3, the second coating head 3 At a position downstream of the conveying direction A of the fabric material W relative to the first finishing head 1, the paint P is applied on the second surface (surface) of the fabric material W so as to be consistent with the ...

Abstract

A double side coating device which can maintain a thickness of a coated film in constant has a first coating head (1) that coats a first surface of a web material (W) with a coating material (P), two or more vacuum conveyors (4) that are placed downstream of the first coating head (1) in a conveying direction for the web material (W) and have a endless belt (7) formed with a number of through holes (9) and a vacuum chamber (8) sucking the web material (W) through the through holes (9) so as to suck uncoated portions of the first surface of the web material (W), and a second coating head (3) that is placed opposite to the vacuum conveyors (4) and coats a second surface of the web material (W) with a coating material (P).

Description

technical field [0001] The invention relates to a double-sided coating device for coating paint on both sides of fabric materials. Background technique [0002] When it is necessary to apply the paint to both sides of the textile material, generally a single-side coating device is used to apply the paint to one side. Next, roll up the fabric material after the paint dries. The rolled up fabric material is placed again on the single-side coating unit to apply the coating to the back side. In addition, there is also a continuous coating device that first coats and dries paint on one side, and then coats and dries the paint on the opposite side. [0003] With the increase in demand for electric vehicles and the like, high energy density and low price of rechargeable batteries are strongly demanded. In the manufacture of rechargeable battery cells, there is a need for a coating device that can more uniformly coat the active material on both sides of a metal foil electrode. ...
