Title: Louvering method
Inventor: MIYOSHI IKUO
IPC: B21D28/12
Filed: 1979-10-26
Abstract: PURPOSE: To perform good louvering inexpensively with good productivity by forcing the work which is moving by abutting its louvering surface to two pieces of plane cutting blades, into between the cutting blades by means of the teeth of a gear-type louvering roll which is revolving.  
     CONSTITUTION: The work 1 is moved forward at a predetermined speed by pinch rolls 4, 4. If a gear-type louvering roll 3 is revolved at a predetermined speed in the same direction as the advancing direction of the work 1, the work 1 is louvered by cutting blades 2a in the process that the tooth of the roll 3 enters between the plane cutting blades 2, 2, whereby the work 1 is louvered. At this time, plate retainers 5, 5 for preventing floating prevent the work 1 from slacking on both sides of the louvering part. In addition, the louver of a louvering width W is formed by the width W of the roll 3.
