ABSTRACT:
A can is provided that includes a tubular can body having a separation line extending from one end to the other with a label over it to prevent the separation line from opening during shipment or storage. The label includes a partial circumferential collar cut extending from one edge of the label material toward the other edge and having a termination point spaced from the other edge of the label. According to one method of manufacture the cuts in the label are formed by severing the label stock just before it is wound upon the fiber body during the manufacture of the tube from which can length pieces are cut. The knife is moved rectilinearly parallel to the tube with the same component of velocity that the label has parallel to the axis of the tube thereby providing a cut in the label at right angles to the can axis.
