ABSTRACT:
A can forming method and apparatus wherein cut-burrs of a can blank are removed from the ends thereof and an adhesive film is stuck onto the preheated ends of the blank and, then, said ends are subjected to high-frequency induction heating for melting said films to join said ends together in such a manner as to prevent edge effect and associated deformations from occurring, thereby to form a lapped seam having a remarkably high adhesive strength substantially without pin-hole formation.
