With Plural Tool Stations Patents (Class 83/357)
  • Patent number: 7798039
    Abstract: The invention relates to a cross cutting device and a corresponding operating method for manufacturing cut-out portions from a flat material web which is moved in a direction of transportation. The device has two cross cutting units which each have a fixed blade and a rotating blade arranged on a rotational element, and said cross cutting units are spaced apart from one another in the direction of transportation. The second rotational element can be connected to a suction device in such a way that in a case of application the cut-out portion is at least temporarily secured on the second rotational element. According to the invention, the second rotational element has, along its circumferential face, a plurality of zones, to which suction air can be applied individually and/or in combination, in order to secure cut-out portions of different formats.

  • Patent number: 6065379
    Abstract: A finisher provided with a punching unit which punches a sheet. The punching unit has five punching rods, a drive shaft which rotates to drive the punching rods, five pairs of circular cam and eccentric cam which are fitted around the drive shaft and a switching board which moves the drive shaft in its axial direction reciprocally at a specified pitch. With a one-pitch movement of the drive shaft in its axial direction, three of the five punching rods (in a three-hole mode) or two of the five (in a two-hole mode) come into contact with the respective eccentric cams, and the three rods or the two rods are moved to make three holes or two holes in a sheet. The selection between the three-hole mode and the two-hole mode is automatically carried out in accordance with the sheet size.

  • Patent number: 4648862
    Abstract: Apparatus is provided in which booklets of interleaved cigarette papers can be made from continuously moving strands of strip paper in which a cutting knife used to sever the paper strips precisely follows movement of the strip. Movement of a driven input shaft is brought onto the moving platform and used to operate the cutting knife. Paper from bobbins is converged by formers and a spreader into a strand advanced by nip rolls through a cutting station. The knife in the station cuts a booklet from the strand while the station moves with the strand. A driven rotatory shaft of non-circular section transmits its rotation to a sleeve that slides therealong as the station reciprocates relative to a shaft. The sleeve is operably connected e.g. by gearing or by a cam and follower to the knife so that rotation thereof brings about the cutting movement.
