An elongated strip of sheet material is transported over a frame and along a transversely movable carriage on which upper and lower circular rotary cutting knives are mounted to slit the strip longitudinally into a desired portion to be processed immediately and a remnant portion for later use. The free edge of the desired portion is urged against a longitudinal guide, adjustably secured to the carriage, for adjusting the width of the desired portion. The strip is urged against the guide by a vertical crab wheel, locatable against the strip, and disposed at a slight acute angle to the longitudinal direction of the strip. The carriage and the guide are freely movable in a transverse direction to accommodate non-linearities in the strip.
