  • Patent number: 4674258
    Abstract: A method and apparatus for inserting insert items into an enclosure, the ert items being selectively compiled by data coding. At the insertion station of the apparatus the insertion items are inserted without reduction in speed by top belts and bottom belts, past lateral insertion guides which are pivoted into the inside edges of the enclosure, directly into the enclosure which is aligned by means of movable cams operated in timed relation to the apparatus and which is opened by top and bottom vacuum devices. The filled enclosure is then conveyed by a segmental roller such that the insertion items retain their speed throughout the insertion operation and do not stop.

    Inventors: Gunter Ehlscheid, Klaus Munsch
  • Patent number: 4586598
    Abstract: A method and apparatus for delivering articles from a high-speed production achine manufacturing hygienic articles, such as sanitary napkins, whereby the sanitary articles, which are separated from the production line and transported at high speed, are turned, aligned and slowed down successively, whereby the interval in the timed sequence of the articles is reduced significantly. Packs of the articles containing a preselected number of units are formed from the flow of sanitary articles so slowed down, and delivered for further processing.

  • Patent number: 4537588
    Abstract: A rotary punch device for making window cut-outs in envelopes and cardboard oxes, with a clamping device for clamping a metal foil having a cutting edge etched out of the foil material. Vacuum bores in the cylindrical surface of the rotary punch retain the material for treatment in position while the punched-out portion of the window is initially also retained by a vacuum and blown away by an air blast on completion of the punch operation.

  • Patent number: 4160894
    Abstract: A desired pattern to be cut from a moving web of material by a focused laser beam is traced by eccentrically mounting the focal lens 3 in a rotatable carrier 4. The lens may also be radially displaceable (FIG. 3), inclined and rotatable (FIG. 4), doubly rotatable (FIG. 5), and/or the carrier 4 may be linearly displaceable (FIG. 6). By suitably and simultaneously controlling the various motion parameters, whose resultants are superimposed on one another, any desired cutting pattern can be traced. The movements are primarily uni-directional rather than oscillatory, which greatly simplifies the implementing hardware, and since all of the laser beam reflecting mirrors involved are fixedly mounted and move only in planes parallel to the web, the laser beam focal length always remains constant.

  • Patent number: 4049945
    Abstract: A method and apparatus for cutting a predetermined pattern in a moving web of material, such as paper, cardboard or the like is disclosed wherein a laser beam is deflected by a series of pivotable mirrors. The pivoting of the mirrors is controlled so as to cause the laser beam to trace and cut a predetermined pattern. The laser beam moves only in rectilinear motion, as does the web of material to be cut. Since the directions of motions are not parallel, any pattern may be cut by controlling the relative speeds of the laser beam and the moving web of material.

  • Patent number: 3935799
    Abstract: Blanks removed from a paper web are cut for the making of card envelopes with a printed closure or for the making of so-called banker envelopes with a broad closure. Blanks cut for the making of card envelopes must be turned in their plane before being conveyed for the following processing. The apparatus for turning the blanks includes a turntable with suction air bores, segmented rollers, a belt acting as a slideway and conveying chains.
