Abstract
A method of coining the score line of container end panels having displaceable portions includes holding a portion of the end panel and coining the score line area thereof between the tapered peripheral edges of the ends of a coining punch and a coining die while controlling the flow of material from the coined area. The apparatus includes a pressure sleeve for engaging a portion of the end panel against the top of the coining die, a control die for supporting the remainder of the end panel and a coining punch for engaging the end panel in the area to be scored. The coining punch and coining die are provided with tapered or beveled shoulders which cooperate to coin the metal therebetween.
