    Abstract: A cutting assembly includes a knife assembly having a knife holder and a knife blade, a counter knife, and a scoring tip holder. In one arrangement, the counter knife is secured to a ring strander drum, the knife holder and scoring tip holder are carried by a clamping element, and knife blade is disposed between the counter knife and the knife holder. In a closed position, the clamping element causes the knife and scoring tip holders to generate a compressive force against the counter knife, thereby securing the knife blade within the cutting assembly. In an open position, the clamping element positions the knife and scoring tip holders in a spaced relationship relative to the counter knife, thereby allowing removal of the knife blade from the cutting assembly. Accordingly, an operator can replace the knife blade in the cutting assembly without having to remove the entire cutting assembly from the ring strander device.

  • Patent number: 6178864
    Abstract: A device for sawing stacks of panels comprises cutting means consisting of a pair of similar carriages located on opposite sides of the stack. Each carriage mounts a first and a second circular saw and a first and a second circular scoring saw. Both carriages can move in two directions along an axis transversal to the feed axis of the stack so as to make a first and a second cut to corresponding defined first and second cutting depths and substantially coinciding in a vertical plane in such a way as to saw right through the stack of panels.

  • Patent number: 5713260
    Abstract: The invention pertains to an apparatus for the precise adjustment of a longitudinally movable component on a spatial axis, especially for the adjustment of the lateral position of the pre-scoring saw blade of a circular saw. This apparatus distinguishes itself by a threaded bolt that is movable around its longitudinal axis, which is parallel to the spatial axis, and has two coaxial thread sections of identical thread orientation and unequal thread pitch. A first thread section engages in a first threaded hole that is immovable in the longitudinal direction of the spatial axis, while the other threaded section engages in a second threaded hole on the longitudinally movable component.

  • Patent number: 5287786
    Abstract: A portable electric cutting and scoring saw for use on laminated or veneer products is disclosed. The scoring saw is disposed in front of the cutting saw and turns in the opposite direction. The saw is designed primarily for the craftsman cabinet maker where the use of large industrial bench saws is not feasible. In one embodiment, the scoring saw cuts at a fixed depth and the cutting saw depth of cut can be varied by changing the blade with one of a different diameter. In another embodiment, the cutting and scoring saw depth of cut and angle of cut can be adjusted simultaneously with depth and tilt adjustments. In addition, in this embodiment, the saw motor can be easily removed and replaced with one of different horsepower and R.P.M. In yet another embodiment the electric motor has a battery power-pack attached thereto that can be readily recharged. The battery power-pack makes the portable electric cutting and scoring saw completely self contained.

  • Patent number: 5275075
    Abstract: An apparatus and method for forming a fold construction in a triple wall corrugated paper board comprises a pair of spaced apart main frame plates having four support plates connected therebetween in a direction which is transverse to a feed direction for the paper board. A pair of shaft carrier plates which have linear bearings thereon, are mounted for sliding movement to the support shafts between the frame plates. Spreader tubes are engaged around the support shafts for maintaining a selected and accurate distance between the carrier plates. Upper and lower shafts are rotatably mounted between the carrier plates and carry knives, scoring members or other fold forming elements for scoring or cutting the paper board to form segments of the fold construction. A table is fixed between the carrier plates that cooperates with a hold down roller which is rotatably mounted between the plates, to hold the paper board down and prevent curling or warping as the fold construction is formed.

  • Patent number: 5193428
    Abstract: The disclosure herein describes an attachment assembly for mounting to a conventional bench saw; the assembly comprises a rigid member which is mounted to the power-operated main shaft of the bench saw. The member has two projecting rods at one end thereof which are adapted to engage a spring biased pin-carrying plate pivotally mounted to a movable structure of the bench saw; the function of the pins is to fixedly secure the rigid member to the movable structure after the attachment is installed and the tool fixedly set for a cutting operation. The cooperation of the projecting rods with the pins is such as to prevent vertical, lateral and angular movements of the member which would otherwise exist due to the reaction forces exerted during the cutting operation whilst permitting at all time controlled vertical and angular positioning by means of table saw handwheels.
