  • Patent number: 4879935
    Abstract: A cutter in which a reciprocating knife is driven by an eccentric mechanism. The knife has a drive portion that flexes laterally in a plane perpendicular to the drive axis of the eccentric mechanism. The eccentric drive axis is offset along the perpendicular plane away from the axis on which the knife reciprocates. The offset of the eccentric drive axis allows the flexible drive portion to be kept straighter during the downstroke than in previous cutters. The increased straightening provides greater columnar strength and reduces deflection and stress of the drive portion during the time the knife is in compression. During the upstroke the knife is bent to a greater degree than in the previous cutters, but during this time the knife is in tension, the tension forces opposing rather than aiding the bending. The offset therefore provides for a longer service life for a blade of equal size or allows a reduction in size and mass of the knife to maintain an equivalent service life.

  • Patent number: 4685363
    Abstract: A bed for supporting sheet material to be cut or otherwise worked on is made of a densely packed array of relatively short, stiff bristles with pointed upper ends which penetrate the sheet material to inhibit it from moving laterally relative to the bed. Vacuum may be used in the space containing the bristles to aid in holding the sheet material to the bed and to normalize the holding effect of the bristles with respect to different sheet materials. Pressurized air may also be used in the bristle space to aid in removing cut sheet material from the bed and the bristles are shaped to facilitate such removal. Various different cutters are useable with the bed to provide a complete sheet material cutting machine.
