ABSTRACT:
This disclosure relates to the formation of a can body having at least one necked-in end portion wherein at least the end portion of the can body is of a lapped construction with a deformable bonding material therein. It is customary to neck-in ends of can bodies utilizing a necking die with a floating center post. The clearance in such die construction takes into consideration the extra thickness of the side seam. It is now proposed to make the clearance between the die ring and the center post such that when the necking in occurs, the side seam will be compressed, thereby assuring side seam end portions of a uniform thickness. It is also proposed to effect a reduction in the thickness of the deformable bonding material which will provide increased seam strength, better creep resistance, and last, but not least, superior double seaming latitude because of uniformity and consistency of dimensions.
