Abstract

Weld free metal bottles mfre. Cold formed aerosol can blanks with the open end worked in four stages in turn, the first two stages in particular being inserted in the tool holder where the tool makes a conical circular movement 90 degrees to the cam axis, as the tool coupling rod is displaced eccentrically to the revolving drive axle. The four stages are (i) edge folding by means of a tapered tool head with rounded grooves to turn over the can edges (ii) reduction in can diameter using a tool conforming to a slightly oversized can shape. (iii) edge trimming by rotating cutters (iv) edge over-lapping by rotating rollers.
