ABSTRACT:
Apparatus for use in an automatic and continuous manufacture line for manufacturing the outer cylindrical cases of dry cells comprising a former, line conveyors and a rotary flanger. Every rectangular blank shifted into the former is pre-formed by a pre-curl punch to form a desired arc and this pre-formed blank is then rolled around a forming roll to form a cylindrical body. The line conveyors serve to feed the cylindrical bodies discharged from the former in a horizontal direction, then in a vertical direction and then in a direction slanted downward in such a manner that the longitudinal axis of each of the bodies is always along the feeding direction, and to turn each of the bodies by 90.degree. at the end of the line conveyors. The rotary flanger receives each of the bodies continuously fed from the line conveyors in each of recesses provided around the outer circumference of a rotary feed turret and presses both ends of the body in such a manner that only one end of the body is bent inward to form a flange of an outer cylindrical case.
