ABSTRACT:
An apparatus for accurately and efficiently cutting a web of sheet material into individual cut segments, and which comprises a pivotal rocker arm, and means for periodically oscillating the rocker arm which includes an endless chain having one or more cams carried thereby. Each cam is positioned to operatively engage the rocker arm during its traverse of a portion of the trackway followed by the chain to thereby oscillate the rocker arm. The rocker arm is operatively connected to a pair of cutting knives so the knives oscillate therewith, and toggle means is provided for actuating the cutting knives during each forward oscillation thereof.
