ABSTRACT:
Portable apparatus for connecting panels with an interlocking seam is disclosed. The apparatus includes three rollers disposed in a triangular configuration. Two guide rollers support connecting flange portions of the panels and a forming or hem roller turns a terminal section of one connecting flange portion back to form the seam. A larger hem roller reduces forming stresses and improves quality. Apparatus also connects panels by seaming a cap over adjacent connecting flange portions. The apparatus may be manually driven or motor driven.
