ABSTRACT:
Metallic wire card clothing is provided having a sharpened leading edge on each of the longitudinally aligned teeth formed in a metallic strip by an apparatus which includes a punch. During punching, the relative direction of travel of the punch is illustrated as inclined at an acute angle in relation to the moving strip and a die cooperating therewith. The method contemplates thus inclining the strip and while the strip is so inclined, punching the teeth as the strip is continuously fed past the die. The strip may be inclined in respect to the direction of travel of the punch either transversely or longitudinally, preferably, both.
