Mandrel for holding cans during trimming - has hard disc with cutting edge mounted with spring loading between main mandrel parts

摘要

The mandrel (1) has the metal tin (21) mounted on it and consists of two main parts (5, 6) which are screwed together. In between the two parts are mounted, a hard disc with cutting edge (27) and a number of axially movable spring loaded segments (11). A combined rotating pressing tool and cutter is mounted with its axis parallel to the mandrel. The tool consists of a ring (20) mounted over an elastomer ring (19) and a hard disc (17) with cutting edge (26). This edge is in line with the cutting edge on the mandrel. When the tool is pressed against the tin or the mandrel, the disc will trim the edge of the tine, while the elastomer ring reduces the dia. at the top of the tin.
