Abstract: The present invention entails a rotary cutting die having one or more scrap strippers secured thereon for stripping scrap corrugated board pieces from adjacently disposed scrap cutting blades during a corrugated board die cutting operation. Each scrap stripper comprises a resilient member having a base and an angled flexible finger extending from the base so as to define an open area between the angled finger and the base. During a die cutting operation, the entire scrap stripper including the angled finger and base is compressed as the stripper passes through the nip defined between the cutting die and an associated anvil. As the stripper exits the nip, it expands causing the underlying scrap piece to be stripped from adjacently disposed blades. In addition, the angled finger extending from the base extends outwardly and engages the underlying cut piece of scrap and pushes or urges the cut scrap against the underlying anvil.

Abstract: The invention is a magnetic knife sheath that permits easy transport and protection of knives in a relatively small sheath. The sheath has either one or two magnetically charged faces. The user places the knife blade against a magnetically charged face and the knife blade is held in place by magnetic attraction between the knife and the magnetically charged face or faces.

Abstract: A folding knife according to one embodiment is provided and includes (a) a handle defining a blade cavity; (b) a blade having a first end which is pivotably coupled to the handle about a pivot; and (c) a biasing element disposed within the blade cavity of the handle. The blade has a detent formed therein on a lower edge thereof proximate to the pivot. The biasing element has a fixed first end and an opposing free second end which has a rounded ball member formed thereat. As the blade is closed towards the retracted position, the blade contacts and deflects the second end of the biasing element until the rounded ball member of the second end engages the blade detent, resulting in the blade being held in the retracted position.

Abstract: Apparatus and methods are disclosed for cutting a sheet of material into single supports where each of the single supports has an array area to which is bound an array of chemical compounds. The sheet comprises a plurality of score lines. The apparatus comprises an input conveyor, an output conveyor, a driver for moving the sheet from the input conveyor to the output conveyor and a breaking mechanism for breaking the sheet into single supports. The input conveyor, the output conveyor and the driver are each adapted to move the sheet without contacting the array area and an area on a surface of the support opposite the array area. Likewise, the breaking mechanism breaks the sheet into the single supports along the score lines without contacting the array area and an area on a surface of the support opposite the array area.

Abstract: A cutting system includes a bandsaw employing a saw blade with an improved cutting edge. The system may employ an upper tensioning assembly and/or a lower tensioning assembly to offset the blade with respect to conventional bandsaw arrangements for applying a continuous tensioning force against the blade during use. In use, the system increases the quality of the cut and provides a straighter cut while decreasing the amount of dust generated in the cutting process as compared to conventional methods, namely, the use of circular saws.

Abstract: An efficient and safe device designed to perform the difficult task of opening tightly fitting Shrink Wrap plastic packaging material and security tape around a product or product case, particularly that used for the distribution of CD-ROM'S, DVD'S, videogames, and videotapes. The device quickly cuts a clean slit opening in the Shrink Wrap and security tape along the inserted edge of the packaged product. The cutting element of the device can be in the form of a wire or blade, and function via heating, mechanical cutting action, and/or ultrasonic vibration. A multiple-capacity alignment channel guides various shaped products into proper cutting position. Sensors may activate the cutting/slitting action, with adequate heat, vibration, and/or mechanical cutting being applied for a time period sufficiently long, or until sufficient temperature is reached, to cut through the Shrink Wrap material and security tape without damaging the underlying product or product case.

Abstract: A linkage device for coupling a linear positioning apparatus to a machine includes a pair of coupling mechanisms formed of plural plate members in various configurations.

Abstract: Provided is a method for repairing an aperture in a panel in which, a) a plug is inserted in a such aperture to fill same and project above the surface of the panel, b) the plug is adhered in the aperture and c) the plug is flush cut with such surface to repair the panel. Also provided is a tool for flush cutting such projection wherein a blade is mounted across a frame, which blade is mounted at about 90 degrees to the plane of such frame so as to be parallel with the surface of the panel when the frame is mounted upright thereon, to provide clearance for the hand that guides the frame while flush cutting the projection from the panel. Desirably the ends of the saw blade are recessed between smooth feet of the frame so that the blade is elevated slightly above the panel surface, to reduce or avoid scratching thereof during the flush cutting step.
