  • Patent number: 3977287
    Abstract: A cutting blade for cutting a multi-layer stack of fabric sheets comprises a relatively flat elongated blade body having a leading edge and a trailing edge. The leading edge of the blade body has a knife edge for cutting through the multi-layer stack of fabric sheets as the cutting blade is moved forwardly into the stack. A bevelled tip is provided on the cutting blade for cutting through the fabric sheets as the blade makes a downstroke through the stack. The bevelled tip has a leading point at the leading edge of the blade and a trailing tip at the trailing edge of the blade. The leading tip pierces the top sheet of the stack and defines a rearward facing upwardly angled cutting edge which imparts a forward acting force on the blade to balance the rearward acting force imparted to the cutting blade by the forward cutting movement of the leading edge as the cutting blade moves forwardly through the stack.
