  • Publication number: 20130133492
    Abstract: With known trimming shears having a pair of scrap-cutting blades on the discharge side, the moving upper scrap-cutting blade must be moved as closely as possible past the trimmed plate edge in order to push the cutoff edge still hanging on the plate downward against the lower fixed scrap-cutting blade, which requires precise adjustment of the upper scrap-cutting blade. To that end, according to the invention, the distance between the upper scrap-cutting blade (2) or the lower scrap-cutting blade (3) and the trimming blade plane (5) is set prior to trimming in accordance with the thickness of each heavy plate (10) to be trimmed by displacement of the upper scrap-cutting blade (2) and/or the lower scrap-cutting blade (3) in a displacement direction with at least one component transverse to the trimming blade plane (5).

  • Patent number: 4738175
    Abstract: A defect detection system is especially applicable to string type potatoes for removing the black spots and includes removing or sorting out potatoes with black spots. It includes a pair of line scanning cameras focused on opposite sides of a vertical on a common line, spaced above the conveyor belt to the height of the potato. Such opposite sight lines provide for effective sensing of leading or trailing edges of the potato. To provide for effective cutting, the cutting blade units have offset blades to allow overlap and a spacing so that areas of uncertainty created by the two cameras are eliminated. To minimize down-time of the system, the vision light, power and punch modules are separately removable. Moreover, they are located on a cantilevered base above the moving belt. This cantilevering in conjunction with pivoted supports allows for a seamless belt and easy removal of that belt.

  • Patent number: 4548114
    Abstract: A cylindrical body resembling a piece of pipe has the sharp edge of a utility-knife blade extending into the bore of the body to cut a longitudinal slit in the wall of a piece of plastic tubing that is pushed or pulled through the bore. A removable stop protruding into the bore momentarily stops the piece of tubing until another utility blade, connected to a guide and handle positioned at an angle across the cylindrical body, is pulled into the slitted end of the tubing to cut on a line that intersects the longitudinal slit. A pointed angular piece is thereby cut out and removed to leave in the end of the piece of tubing a notch with a surface slanting outward toward the end of the piece of tubing for functioning as an inclined plane to spread the tubing. A linkage connected between the angular guide and the stop removes the stop to permit completion of slitting. A handle with a triangular blade is also connected transversely to the cylindrical body for cutting the slitted tubing into lengths.

The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.

  • Patent number: 4255993
    Abstract: A method and apparatus for acting on angle irons or the like. A vertical stack of angle irons is provided and the angle irons are fed one at a time to a punching position. At the punching position a hole of selected size is punched in the angle iron, and the angle iron is fed from the punching position in a linear direction of movement to a cutting position. The length of the angle iron to be cut is determined by measuring the length of angle iron in the direction of movement past the cutting position, and the angle iron is cut at the cutting position. Cutting is accomplished using a crankshaft with at least one cutting blade operatively connected to the crankshaft at a portion thereof offset from a line between the bushings, guide structures being provided for guiding the linear movement of the cutting blade. Each cut angle iron is removed from the cutting position in a direction normal to the linear direction of movement of the angle iron to the cutting position.

  • Patent number: 4202232
    Abstract: Apparatus for trimming the front, head and foot ends of brochures has a stationary platform which supports one brochure at a time. A first knife which trims the front end of the brochure on the platform descends in a vertical plane ahead of two additional knives which thereupon simultaneously trim the head and foot ends of the same brochure as soon as the first knife completes the trimming of the front end. The first knife is pivoted forwardly and away from the additional knives while the additional knives move toward and trim the brochure on the platform. This insures that the first knife is held out of the way while the additional knives move to positions in which their forward ends extend beyond the trimmed front end of the brochure.
