  • Patent number: 9302408
    Abstract: A miter box fence system includes a fixed vertical portion and a movable portion that may be moved with respect to the fixed vertical portion. The movable portion includes a notch that allows one edge of crown molding to be placed in the notch while the other edge of the crown molding extends towards the fixed vertical portion. The movable portion may be moved with the crown molding in place until the crown molding makes appropriate contact with the bottom of the notch and with the fixed vertical portion. The movable portion may then be secured in place. Because the notch in the movable portion creates a stop for cutting crown molding, and because the notch is below the flat portion of the movable portion, the miter box fence system may be used to cut both crown molding and flat stock without modification.

    Abstract: A fully automated optical fiber cutter includes a fiber cutter body and a fiber clamp. The fiber cutter body includes a cutter cover body and a cutter main body, which are pivotally connected. Inside the cutter main body is provided with a movable blade-fixation seat, which comprises a blade for fiber cutting. The fiber clamp is installed on the cutter main body. The fiber clamp includes a clamp main body and a clamp cover body, which are pivotally connected. The cutter cover body, the clamp cover body and the blade-fixation seat are linked by a linkage component. When the fiber in use, the cutter cover body is pressed to drive the clamp cover body close and push the blade-fixation seat to move, thereby the blade is aligned to cut the fiber.

  • Patent number: 8528453
    Abstract: High-pressure water jet cutting techniques generate numerous handling problems both for the plates being cut and for cut parts. These problems can be resolved by the device according to the disclosed embodiments. This device includes a plurality of wires held under stress at a predetermined stress level above a plate being cut. These wires intercept a jet cutting the plate. This interception results in the creation of a micro-fastener holding the cut part to the plate. This micro-fastener can be easily broken. The plurality of wires also prevents the boiling effect of water in a cutting pool, this boiling resulting from the impact of the water jet in the pool.

  • Publication number: 20120079929
    Abstract: A film clamping and cutting device of a film wrapping machine is revealed. A connecting plate of a film clamping and cutting unit is located by a braking part. Moreover, by moment of a rotating machinery before stopping, a film clamping and cutting unit main body assembled on the rotating machinery is driven to continue moving. Under the movement of the unit main body, a pulling force is generated by a pull cord arranged between the connecting plate and a vertical-wheel of the unit main body. The pulling force rotates the vertical-wheel so that both a film clamping and cutting rod assembled with the vertical-wheel and a clamp fall toward a blade block to clamp and cut off a film. The film is also pulled and cut by an elastic recovery force of the film clamping and cutting rod. Therefore automatic film clamping and cutting is carried out.

    Abstract: A method for optimizing the cutting of sheets of material that are stacked on a bench in a cutting machine. Before cutting the sheets, a beam descends to hold the sheets fast while guillotine blade descends and cuts the sheets. After the sheets have been cut, the blade and beam are lifted, with the lower edge of the beam following the sharp edge of the blade. A definite distance between the blade and the top of the stack is determined while the blade rises after cutting the sheets. The rise of the blade is terminated at the upper end of that distance, which is determined by a pick-up mounted stationary on the holdfast beam. This pick-up detects the position of the rising blade in relation to the holdfast beam.

  • Patent number: 4637288
    Abstract: An improvement is set forth in a sawing apparatus having a workpiece support structure and an operator moveable electrically operated saw having a first normally biased off switch controlling application of electric power thereto, the switch being positioned to be controlled by the hand of an operator which controls movement of the saw. The improvement comprises a device adapted for gripping, positioning and clamping a workpiece relative to the workpiece support structure and a second normally biased off switch connected in series with the first normally biased off switch, the second switch being positioned to be controlled by the off hand of the operator while the off hand is utilizing the device. Since both hands of an operator must be holding onto normally off switches and since both switches are in positions removed from the area of movement of the saw blade, the operator is protected from accidently cutting himself.

  • Patent number: 4589314
    Abstract: The present invention relates to an apparatus for cutting motion picture film negatives. The improvements in the present invention film cutting apparatus enable the film cutter to cut the motion picture film negative with a precise, even, clean cut at a location mid-way between adjacent frames of film footage. This is necessary when using a new technique of negative cutting and splicing that allows no frame loss and still maintains all of the requirements of professional (state of the art) motion picture film processing. This has never before been done. The improvements include individual film seating plates which press the lengths of motion picture film to be cut against individual film support and ejection plates to assure that the lengths of film are securely held prior to and during the cutting operation. The present invention also provides safety features to assure that the operator will not accidentally cut himself during the operation.

  • Patent number: 4313359
    Abstract: A device cuts vertically fed paper against a cutting edge by means of a carriage driven cutting wheel. There is a chute means downstream from the cutting edge and secured to a pivotable guideway bar, rotated by movement of the carriage during cutting operation. The paper is held against the cutting edge during cutting on one side by the chute means which tilts the paper to be cut toward a deposit tray and on the other side by a pivotable flap biased by a pressure roller mounted on the carriage. In the non-cutting mode, the flap and chute are substantially coextensive to help provide a gap-free pathway for paper being fed into the device.

  • Patent number: 4228707
    Abstract: The invention relates to cutters, and provides a cutter comprising a base and a cutting-blade carrying arm. The base and the arm may be parts of a one-piece plastic molding which incorporates a connection between the base and the arm, which connection permits movement of the arm relative to the base during the cutting action. The arm may carry at least one flexible member which engages the material to be cut prior to engagement of the material by the cutting blade, whereby the material is restrained from movement during the cutting action.
