Abstract (en)
[origin: US4648299A] A tear-open strip is severed from a band of material having a width equal to the desired length of the tear-open strip by cooperation between a stationary knife-edge defining member and a pivotal knife-edge defining member. The knife edges form chords of a hyperboloid of revolution and are inclined relative to one another. The pivotal knive-edge defining member is provided with suction ports adjacent to the cutting edge whereby a severed strip may be transported by the knife to an intermittently moving sheet of packaging material to which the strip is subsequently bonded.
