  • Publication number: 20040016332
    Abstract: A blade holder for a mat board cutting machine, the blade holder including an open sided recess for receiving a blade, a screw for adjusting the extension of the blade from the recess and a magnet for releasably holding the blade within the recess. A cutter head for use with a mat board cutting machine, the cutter head including a blade carrier pivotably mounted to the cutter head for holding a blade holder. The blade holder includes an open sided recess for receiving a blade, a screw for adjusting the extension of the blade from the recess and a magnet for releasably holding the blade within the recess. A mat board cutting machine including a clamp for holding mat boards against a deck and a cutter head mounted to the clamp for cutting the mat board. The clamp is held between clamp hinges which include screws to exert a compressive force against the end of the clamp.

  • Patent number: 6572326
    Abstract: The present invention comprises a cart loading machine that provides for improved operating efficiencies, and includes a cart loading station, an infeed conveyor, a pattern forming area, a carrier sheet and wiping mechanism, and a fork loading apparatus. The cart loading station includes a framework defining a cart loading position and a cart waiting position. With the carrier in its extended position having carried a fully formed pattern to the cart loading position, a wiping mechanism is extended from beneath the carrier plate to contact the bundles as they sit on the carrier so that when the carrier moves back to its retracted position, the bundles are blocked and stripped therefrom. The wiping mechanism is then retracted below the carrier to permit the loading of a subsequent pattern of bundles thereon. This wiping mechanism eliminates the need for an overhanging blocking mechanism thereby permitting more efficient loader design and easier access to the pattern forming and bundle stripping areas.
