An apparatus ( 10 ) and method for crosscutting a web ( 12 ) of material has employs a knife ( 24 ) that is angled relative to the surface of the web. Orienting the knife so that an upper portion of the cutting edge engages the web after a lower portion of the cutting edge engages the web facilitates cutting the web at a transverse cut angle (beta) of about 20 degrees. Simultaneously orienting the knife so that the upper portion of the cutting edge engages the web at a different position along the side edge than the lower portion of the cutting edge facilitates cutting the web at a horizontal cant angle (alpha) in the range of about 10 degrees to about 50 degrees.
