Title:
COMPOSITE SHEET MANUFACTURING DEVICE AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/069751
Kind Code:
A1
Abstract:
Provided are a composite sheet manufacturing device and manufacturing method with which it is easy to more rapidly manufacture composite sheets, and which make it possible to manufacture composite sheets of stable quality even when such manufacturing is done more rapidly. A second roller (22) having multiple first projections (22a) and a third roller (24) are disposed so as to be adjacent to a first roller (20) having multiple recessed areas. The outer diameters of the first and third rollers (20, 24) are the same size. The third roller (24) is joined to the first roller (20) with a first gear pair therebetween, so as to rotate at the same rotation frequency as that of the first roller (20). A first sheet (2) that is fed in between the first roller (20) and the second roller (22) is shaped by being pushed into the recessed areas of the first roller (20) by the first projections (22a) of the second roller (22). A second sheet (4) is then superimposed onto the first sheet (2) and is passed through the space between the first roller (20) and the third roller (24), and the first and second sheets (2, 4) are thereby bonded to each other.
