  • 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.

  • Patent number: 5001955
    Abstract: A movement and rotational movement of the movable blade of the paper-cutter of this invention is constructed with a mechanically engaging mechanism such as a screw mechanism or a pinion/rack mechanism, so that there are no technical problems found with the conventional type of the paper-cutters such as slackening and/or cutting-off of the wire and coming-off of the wire from the drum. Moreover, since it is not necessary for an additional means for providing tension force on the wire, a longer-term stable cutting operation can be achieved. Furthermore, since the fluctuation in the manufacturing accuracy and deformation caused during the production process of the screw grooves as well as case body itself can be controlled and minimized by the screw mechanisms to some extent, the strict requirements for components accuracy can be reduced, resulting in an effective cost-down.

  • Patent number: 4979410
    Abstract: The invention is embodied in a tube cutting station in a tube producing mill. The cutting station includes a rotating press assembly and an axially moving cutting assembly. The cutting assembly is accelerated axially to a velocity which matches that of the tubing being produced. Once the cutting assembly reaches the same velocity as the tubing line, the press assembly can cause downward movement of a cutting blade through the tubing. The press assembly of the present invention is alternately rotated in opposite directions to maximize the rotational extent and time available for acceleration and deceleration of the press assembly, and therefore enables the use of lightweight drive motors. Slower acceleration and deceleration also reduces wear on components used to drive and stop the press assembly.

  • Patent number: 4907392
    Abstract: A machine for applying a twist-type tie to the neck of a bag has a path and sets of endless belts which come together at a nip along the path to propel a bag neck which passes into the nip forwardly to a typing zone in the path. Here a twist-type ribbon crosses the path and is secured at its end in a holder. An endless chain carries a pusher tab up to the tying zone behind the bag neck, causing the bag neck to gather behind and deflect the ribbon, then pauses, and thereafter resumes its forward motion to drive the bag neck out of the machine. During the pause a bag clamp secures the bag neck against a surface that is along the path and a needle lifts a portion of the ribbon upwardly behind the gathered bag neck and brings that portion of the ribbon to the holder so that the ribbon loops below the bag neck in the form of leading and trailing segments. While the needle is so extended, a twister hook gathers its leading and trailing segments and twists them together.

    Abstract: The scroll-saw disclosed is constructed so as to make the task of clamping and un-clamping the saw-blade very simple and very quick. The quick-change facility makes it possible for a craftsman to contemplate cutting intricate designs having myriads of internal shapes. The electric motor of the scroll-saw is connected to the blade by means of a clutch. The clutch is operated by a foot-pedal. The blade is kept in constant tension by a spring. The scroll-saw includes a shoe, which is guided from up/down movement--when up, the shoe is clear of the blade--when down, the shoe comes into contact with the blade, and allows the blade to be de-tensioned. Thus, the blade can be un-clamped, and moved to the next internal shape to be cut, while the vertical position of the blade is controlled by the shoe. The movement of the shoe also is controlled by the foot-pedal.

    Abstract: A portable sawmill is constructed to produce dimensioned lumber from logs in remote logging locations. The portable sawmill employs but a single, disk shaped rotating blade which is powered by a relatively low horsepower engine. The engine and blade are mounted upon a carriage which traverses the length of a log to effectuate first a horizontal cut and then a vertical cut with a single saw blade in returning along the length of the log. The blade is oriented for vertical cutting as it progresses along the track away from the operator. The orientation of the blade is automatically reversed at the remote end of the log. The saw blade then cuts the log while in a horizontal orientation as it returns to the operator position. The maximum speed of longitudinal traverse of the carriage is separately adjustable for both vertical and horizontal cuts.

  • Patent number: 4545275
    Abstract: An elongated blade has a notch in its leading edge, with parallel chisel edges adapted to chop through the oriented fibers (boron or graphite) of uncured sheet material as the blade is reciprocated vertically at a high frequency relative to its forward velocity (five cycles per blade width). The notch is about half as deep as the blade width and has a vertical extent (between the chisel edges) of about 60 percent of the blade's vertical stroke. The blade has a lower edge which forms a 135 degree angle with it's leading edge, and which lower edge is spaced below the lower notch chisel edge by approximately the width of the blade.

  • Patent number: 4328724
    Abstract: A block of material such as a clay is fed onto a support comprising spaced apart supports, and a cutting frame, having tensioned cutting wires, is moved in a substantially vertical plane through the block and between the supports so that the cutting wires cut completely through the block without interruption of the cutting motion. The cutting wires lie in a plane extending at an acute angle to the plane of feed of the block. The cut block is then removed from the support. Feeding of the block onto the support and removal of the cut block from the supports occurs in a single plane and are effected substantially simultaneously by means of a pushing device. The method and apparatus of this invention is particularly applicable to the cutting of individual clay batches into a number of individual brick mouldings. An advantage of a preferred embodiment of this invention is that cut portions can be produced without marking of the cutting surfaces and/or the cutting edges of the cut portions.

  • Patent number: 4201104
    Abstract: A glass cutter of the type having a pillar post capable of limited angular movement about a vertical axis is disclosed. The pillar post is provided in a conventional head which is adapted to traverse a glass sheet in one and an opposite direction, and the glass cutter can score in both directions because the tool is designed to trail this vertical axis, and thereby provide a castering action in both directions. The tool is mounted in a small pendulum which is gravity biased to assume a ready position such that traversing movement of the head and pillar post in one direction, in conjunction with engagement between the tool and the edge of the glass sheet itself, moves or swings the pendulum to a first limit position such that the tool trails the said vertical axis achieving the above castering action.
