    Abstract: In contrast to typical machines though, the present invention discloses a device which allows the plate to "float" within the mechanism, so that any inaccuracies in dimensional tolerances between plate and knife are absorbed in a damping of the plate or bed of the mechanism. In this situation, the depth of the cut of the score line can be very reliably controlled, which results in the repeatable manufacturing of a child resistant, yet senior effective package. There is used a spring pre-load for this plate, which is such that cutting takes place yet, as the tool closes, the plate and package come in "metal to metal" contact, assuring "near perfect" cuts of the blister package. Extremely high tolerances are maintained, assuring packages which pass all levels and types of QA testing.

  • Patent number: 5160340
    Abstract: Method and apparatus for skullcap and other bone cutting during autopsy. A power driven rotary cutter in the form of a circular blade saw is mounted on a carrier which moves around the skull of the cadaver and permits the cutter to move radially, toward and away from the axis of the skull. A follower which engages the skull controls the depth of cut so that only the skull bone is cut without damage to the brain tissue in the skull. The cutter is driven by a cable from a remote motor to minimize the weight of the cutter assembly on the carrier. The casing in which the cutter is mounted can be a handpiece of a cable driven tool. The cutter can also be used manually by removing the handpiece from the carrier. Power to the cutter is controlled so that the cutter cuts only bone and stops when soft tissue is engaged by the cutter, which avoids serious damage to soft tissue, and also avoids serious injury to the user if the blade slips.

  • Patent number: 5136910
    Abstract: Flat multi-layered work pieces, such as panels with a decorative or finish surface coating (5), are prescored and cut through by the same saw blade to avoid damage to the surface coating. For this purpose a circular saw (1) is guided along a guide rail (7) and its saw blade (4) is adjustable to a prescoring depth and to at least one lateral prescoring position to make a first prescoring cut only through the cover layer (5) in a sawing direction in synchronism with the blade rotation direction. If necessary, the blade is adjusted to a second lateral prescoring position to make a second prescoring cut only through the cover layer (5) in a cutting direction in synchronism with the blade rotation. Finally, the saw blade (4) is adjusted to its full cutting depth and to a lateral position between the two prescoring positions and a full cut is made through the entire work piece (6) in a sawing direction counter to the rotation direction of the saw blade.

  • Patent number: 5046392
    Abstract: A method and apparatus for severing a length of insulating batting and simultaneously cutting only the insulating material thereof is provided. The insulating material between the severed edge of the insulation batting and the cutting line through the insulating material can be removed to expose a length of backing which can be secured to the uncut portion of the insulation batting length when the insulation batting length is wrapped around a length of a heating and cooling duct or the like. The apparatus includes a pair of rotating cutting wheels rotatably mounted on a carriage movable along an elongate carriage rail. A pinion gear mounted to each rotating cutting wheel for rotation therewith meshes with a rack secured to the elongate carriage rail to cause rotation of the rotating cutting wheel in response to movement of the carriage along the carriage rail.

  • Patent number: 4921563
    Abstract: A method is disclosed for making plastic products that enables adjacent portions thereof to be easily folded into juxtaposed relationship. A hinge is formed by utilizing an angled or curved cutting tool to create a continuous slit which in a preferred configuration (when viewed in profile) is generally L-shaped so that it extends from one surface of the product to a first location that is within the products' body and then extends therein from the first location to a second location also within the thickness of the body. The slit opens onto the one surface and thereby forms a flexible bridge integral with those portions of the product adjacent thereto, the bridge permitting such adjacent portions to be flexibly folded into juxtaposed relationship.

  • Patent number: 4905558
    Abstract: The invention relates to apparatus for cutting a series of spaced-apart continuous linear slits in a sheet of flexible plastics material, for example in the manufacture of an ajustable width blind. In one embodiment the apparatus includes a feed roller for feeding sheeting to be slit to a support means, a plurality of slitting blades movable in a direction transverse to the direction of travel of the sheeting and means for controlling the blades so that they cut to a depth less than the thickness of the material. In a second embodiment the blades are stationary and are adapted to cut in the direction of travel of the material. The blades may be mounted on leaf springs biased towards the material to be cut, means being provided for controlling the biasing force. Alternatively, a stop may be provided to control the depth of cut of the blades.

  • Patent number: 4854205
    Abstract: A cutting device comprising a support roller (8) freely rotatable in both directions to absorb the pressure of cutting, and a carrier (9) movable in the direction of the longitudinal axis of the support roller (8) on which is fastened a cutting tool (26,27) which can be brought into contact with the roll of material to be cut and present on the support roller (8). The improvement comprises lowering of the cutting tool (26,27) into an operating position, and raising from the operating position, by turning of an eccentric element (14,34) coupled with a pivotable arm (17) holding the cutting tool (26,27). The cutting tool (26,27) is suspended on the arm (17) and thereby limited in regard to its raising and lowering movement. A leaf spring (21) fixed on the arm (17) is braced on the upper end (28) of the cutting tool (26,27) to exert a penetrating force on the cutting tool (26,27) when the arm (17)is lowered.
