... 4450EP APPARATUS AND METHOD FOR RESHAPING CONTAINERS An apparatus for reshaping a container 12 includes a mold 210 of the split type. The container 12 has a body member 14, a closed lower end member 16 and a cone-shaped open upper end member 18. The mold 210 has a pair of upper clamping members 250,252 and a lower clamping member 272 which slide along a liner 228. The upper clamping members 250,252 and a seal 262 for closing the container 12 act on the double seam 19 between the upper end member 18 and the body member 14, thus ensuring that the upper end member 18 and the double seam 19 do not deform during reshaping. The seam 17 between the lower end member 16 and the body member 14 is gripped between the lower clamping member 272 and a support member 258. During reshaping, compressed air is supplied to the interior of the container 12, causing it to expand outwardly while the clamping members move inwardly. See figure 5 ...
