  • Patent number: 5603253
    Abstract: A method and apparatus are provided for cutting a decorative groove in a matboard. The matboard is positioned adjacent a guide. A carrier is adapted to be moved along the guide with two blades oriented in separate planes which intersect each other and which lie at an oblique angle relative to the matboard. One of the blades is inserted into the matboard at a selected first depth. The carrier is moved along the guide for a predetermined length of travel to make a first cut in the matboard defining a first side of the groove. The blade is then retracted. Then the other blade is next inserted into the matboard to a selected depth at least intersecting the first cut. The carrier is then moved back to the initial location to make a second cut in the matboard defining a second side of the groove. In a preferred embodiment, the tips of the blades are offset from each other relative to the length of the groove.

  • Patent number: 5503053
    Abstract: A sheet material cutting mechanism for cutting sheet materials two rotary blades and a mechanism for pressing down a sheet material to be cut. When the motor is started, a screw shaft 2 rotates, and a rotary blade assembly 4 starts to move to the right in FIG. 1 . Then, the roller 12 rotates by friction with a frame 1, and a first rotary blade 10 rotates by the rotation of a roller. At the same time, a second rotary blade 20 also rotates by the frictional force generated between the rubber roller 22 and the frame 1. The sheet material, fed into the sheet material receiving portion 17, is pressed by the rubber roller 22 against the surface 5 of the frame 1 immediately before cutting to prevent lifting or bending of the sheet material, thereby producing satisfactory cutting of the sheet material.

  • Patent number: 5327805
    Abstract: Apparatus for fabricating discrete segments of cushioned web material for use as dunnage. The apparatus includes a mobile supply cart having at least one substantially horizontal support arm for receiving the hollow core of rolled web material. The apparatus also includes a separate driven rugation device with feed rollers for directing multiple plies of the web material in overlying, contacting relationship along a single path of travel. The separate cart and rugation device may be removably interconnected for lateral alignment. Driven interdigitized texturing rolls downstream of the feed rollers emboss a raised pattern on the web material, and a plurality of separating rollers downstream from the texturing rolls separate the plies of web material and direct them in divergent paths of travel. Combining rolls recombine the plies of textured web material such that the embossed areas of each ply do not directly overlie each other but are offset, creating void areas between the adjacent plies.
