<p>A method and apparatus for reforming the base profile of a can by using the difference in rotational speed of concentric shafts (A, B) to move a roller (5) radially into contact with the can base. A cam (10) is fixed to one (B) of the shafts and a pair of cam followers (12, 14) is mounted on a support block (6) which is connected to the other shaft (A) via linear bearings (7, 8). The support block also carries the reform roller and causes it to rotate around the can base. (Figure 5)</p> |
