ABSTRACT:
A more versatile and improved mechanism is provided for internally maintaining can side seams uniformly aligned, for instance as they advance from a forming horn for registration with a molten solder jet or equivalent applicator. In a preferred form an elongated cage-type horn extension comprises circumferentially spaced rods or tubes arranged to progressively deflect successive can bodies thereon radially outwardly from circular to ellipsoidal cross-section. The extension incorporates interchangeable slot formations selectively to accurately guide and accommodate different seam widths. The rods or tubes, when worn from use, may be rotated about their axes to present fresh, unworn surfaces engageable with the can interiors on their side seams. The invention insures uniformity of the soldered side-seam joints and avoids interference with lithography on the can bodies.
