  • Patent number: 7861628
    Abstract: A calibration procedure is carried out for determining the displacement distance from a reference point to the center of the blade in a web cutter in a mail inserter. A photosensor is placed near the paper plane of the web cutter to sense a web edge at the reference point downstream or upstream from the blade. At the start of the calibration procedure, the blade is caused to cut the web for providing a web edge. The web edge is moved in a backward and forward motion over the photosensor a few times for determining the theoretical center position of the photosensor relative to the position where the web is cut by the blade. By taking into account the chip-out width, the displacement distance from the center of the photosensor to the center of the chip out blade can be determined.

  • Patent number: 7380484
    Abstract: A method and apparatus for continuous, high-speed production of punched strip having an array of high-tolerance closely-spaced holes with positive ejection of waste punch-out material. A first pair of opposed rotary dies, one a female die and the other a male/female die, punches a first set of holes in a strip fed continuously between the dies, and a second pair of opposed rotary dies, one the male/female die and the other a male die, punches a second set of holes in the strip between the first set of holes, the strip being wrapped about the common male/female die during punching of the first and second sets of holes to continuously index the strip with the two opposed pairs of rotary dies to ensure production of the high-tolerance closely-spaced holes.

  • Publication number: 20080072721
    Abstract: A method and apparatus for cutting segments of wire from an advancing wire strand is disclosed. The segments can have a selectively predetermined length, and are cut from a strand traveling into a machine at a feed speed. The machine includes a moveable cutter that accelerates to the feed speed of the strand in a direction along the strand. A length of strand extending past the cutter is determined at real time based on a signal from a proximity sensor. When the speed of the cutter closely matches the feed speed and when the length of the strand extending past the cutter is determined to be equal to the predetermined length, the cutter is commanded to cut the strand and return to a home position.

  • Publication number: 20070227324
    Abstract: A cylindrical punch member equipped at the leading end thereof with a hole-punching blade is movably supported on a base frame in a hole-punching direction. A drive means is equipped that applies thrusting force to the punch member; a cam follower member disposed between the base frame and punch member engages a cam means disposed at either the base frame or punch member. An oblique cam surface inclined at a predetermined angle with regard to a hole-punching direction is equipped in cam means to give rotational drive force around an axis of rotation to the punch member that is moved in the hole-punching direction by the drive means. This configuration causes each of a plurality of cylindrical punch members to rotate around their axes of rotation when moved in a hole-punching direction by drive means thereby punching a hole in a sheet with a reduced shear force; the centrifugal force of that punch member rotation causing paper cutting debris to be scattered evenly under the punch member.

  • Patent number: 7258049
    Abstract: A method of operating a flying shear for cutting a rolled strip, which includes at least one drum provided with a blade, includes synchronizing a peripheral speed of the blade with a feed rate of the rolled strip, and cutting the rolled strip by effecting a partial penetration of the blade in the rolled strip to produce a weakened location of the rolled strip, and by tearing the rolled strip at the weakened location by a tensile force.

    Abstract: A high-speed shear with a knife, particularly a chisel-type knife with a knife edge, arranged on at least one of two oppositely arranged drums, wherein the knife can be accelerated to the feeding speed of the rolled strip and the drums can be adjusted relative to each other for carrying out a cut. At least one drive unit provided for the drums serves to accelerate the drums to the speed of the rolled strip to be cut and at least one of the drums may be provided with a separately controllable adjusting device. The chisel-type knife of the knife drum is mounted so as to protrude from the cutting circle towards the anvil or the surface portion of the second drum acting as an anvil and to mount the chisel-type knife of the knife drum so as to be resiliently supported against a predetermined restoring force.

  • Patent number: 7097727
    Abstract: A pad forming process forms a stack of sheets, each sheet bearing adhesive on at least a portion of one side thereof. A sheet cutting die is provided having sheet collection cavity therein. A web comprising a linerless elongated sheeting having one side at least partially covered with an adhesive is advanced past the die. The die cuts the web to form a first cut sheet which is retained within the sheet collection cavity of the die. The web continues to advance past the die. The die then cuts the web to form a second cut sheet from the web which is retained within the sheet collection cavity of the die, wherein the second cut sheet adheres to the first cut sheet within the sheet collection cavity to form a stack of sheets.

  • Patent number: 7080584
    Abstract: To produce at least one perforation in a non-woven sheet (N) of fibers or filaments, the sheet (N) is brought into contact with a perforated cylinder (2), equipped with at least one insert (8). Each insert includes, at one end, a plane surface (S), and is provided with a recess (8b) which emerges in the plane surface (S), and which has a sharp edge (8g) formed by the intersection of the inner surface (8f) of the recess (8b) with the plane surface (S). A perforation in the non-woven sheet (N) is obtained by cutting out a portion (P) of the non-woven sheet (N) by shearing of the fibers or filaments of the non-woven sheet (N), between the sharp edge (8g) of the insert (8) and a perforating member (9) driven simultaneously in translation and in rotation about its own axis.
