Abstract
In an initial state of roller hemming processing, an erected flangebegins to be bent by a roller. At this time, a first plateand a receiving faceare brought into tightly contact with each other at a contact pointbetween the rollerand the erected flangeby strongly pinching by the rollerand an auxiliary roller. On the other hand, in portions other than the contact point, the receiving facetends to be separated from the first plateby reaction. Since slider blocksandare movable along railsandon a side of the receiving die, the receiving dierotates clockwise in the drawing about the contact point. A tight contact in the contact pointis guaranteed as the receiving dierotates about the contact point. As a result, the hemming processing with a good shape can be achieved without wrinkling, ruffling, or deformation.
