A container-forming apparatus comprising a movable mandrel supporting the casing and the end member, which closes the open end of the casing and an end sealing station comprising a clamping means in order to press together the edge of the casing, said casing being transferred to the end sealing station by the mandrel, and the edge of the end member, said edge being turned longitudinally towards the casing. The clamping means comprises a piston moving back and forth in the longitudinal direction of the casing, said piston having pushing surfaces approaching the sliding axle in the pushing direction causing the clamping action. The pushing surfaces are the countersurfaces of the clamping members, said clamping members being arranged to turn towards the frame of the clamping means. The countersurfaces form the front portion of the piston, said front portion tapering into a V-shape in the pushing direction in order to turn the clamping surfaces of the clamping members outwards towards the clamping countersurfaces positioned on the frame of the clamping means. |
