Abstract
An apparatus and method are disclosed for plastically deforming and closing an very open, non-cylindrical shell (28) having axially extending lips (20c, 20t) spaced sufficiently far apart to permit a wound spool of strip material to pass laterally between such lips, the apparatus including a pair of closure jaws (670,676) having concave cylindrical surfaces for contacting the exterior surface of such a shell between such lips, the concave surfaces having a curvature corresponding to the desired final cylindrical shape for such a shell; a pivotable arm (608-612) for placing the closure jaws in an open configuration about such a shell and a linkage (614-674) operatively connected to the pivotable arm for closing the closure jaws about such a shell to move such lips into close proximity and form such shell into a cylindrical shape between such lips and thereafter for opening the jaws without contacting the closed shell as the jaws open.
