Title:
LOUVER FIN AND CORRUGATE CUTTER
Document Type and Number:
WIPO Patent Application WO/2006/033382
Kind Code:
A1
Abstract:
A band-like thin plate (13) is formed in a corrugated shape by alternately forming bent sections (15) and flat sections (17), and louvers (19, 21) are formed in the flat sections (17) by cutting and bending up the band-like thin plate (13) in its longitudinal direction (Y). The louvers (19, 21) are side-by-side in a width direction (X) of the band-like thin plate (13) to form louver fins (11). The angle of bending up of louvers (18, 19) is substantially the same in the longitudinal direction (Y) of the band-like thin plate (13).
