ABSTRACT:
The strip 2 is inserted between forming rollers 1a and 1b so that fins 3 are formed on the strip 2. The forming rollers 1a 1b have a line of protrusion protruding radially on the periphery thereof and the protrusion of one roller mates with protrusion of the other roller. A pair of forming rollers or more pairs of forming rollers are employed. A part of the strip 2 sandwiched between side face portions 13a and 14a of the protrusion 13 and 14 is pressed in the direction of the thickness of the strip with a stress between yield stress and maximum stress of the strip 2. To adjust the stress, a clearance G between protrusions is controlled.
