  • Patent number: 5307961
    Abstract: The invention relates to a device for pouring viscous mixtures having solid ingredients including a holder and an exit die rotatably mounted below the holder and having an intake bore through which the mixture passes under pressure. A spiral-shaped stripping element is attached to the holder and has a free end extending downwardly into the intake bore. The exit die rotates with respect to the spiral-shaped stripping element, so that the solid ingredients within the mixture are serially directed through the exit die. The free end of the stripping element extends in the direction of rotation of the exit die.

  • Patent number: 5188212
    Abstract: The invention relates to a rotating transport apparatus for transporting objects from a first conveyor to a second conveyor, each conveyor having a longitudinal extending central axis. The apparatus includes a swivel arm with an axis, and a rotary plate rotatably mounted on the swivel arm axis, extending at least partially to the first and second conveyors. A drive is provided for rotating the rotary plate. Carriers are rotatably mounted beneath the rotary plate, in regular intervals along the periphery of the rotary plate. The carriers have gripper and a carrier axis for counter rotation for consecutively gripping the object, conveyed by the first conveyor. The objects are transported to a second conveyor, and placed on the second conveyor without altering the orientation of the object with respect to the first conveyor. The operating radius between the center of the rotary plate and the carriers is variable.

  • Patent number: 5088707
    Abstract: A method and apparatus for producing numerically correct partial stacks from individual leaves or sheets interfolded in a U-shaped or zigzag form on an interfolder. A double stream is formed from one or more streams of sheets by staggering or guiding together. This double stream is then continuously folded into zigzag form and piled up in a continuously growing stack, from which partial stacks of a specific size are separated. Gaps are formed in the streams of sheets which simplify the introduction of separating elements into the stack. For this purpose, sheets are removed from the streams of sheets and optionally placed accurately in position on successive sheets.

  • Patent number: 5087464
    Abstract: The present invention is directed to a method for producing multi-layered confectionery comprising aligning the confectionery on a conveyor system in rows oriented at right angles to the transport direction of movement of the conveyor system; building up the confectionery layer by layer by a first, a second and succeeding applicators for delivering a confectionery mass deposited onto the confectionery the applicators being arranged one behind the other along the transport direction; optically detecting each row of confectionery before the row reaches the second and all succeeding applicators; generating a signal based upon the position of each row relative to the respective applicator; and this signal controlling the spatial position of the applicator and its application time interval in such a way that the delivered mass deposited by the applicator is placed exactly in a predetermined position onto the row of confectionery passing below the applicators.

  • Patent number: 5067698
    Abstract: A method and apparatus is provided for manufacturing toweling interfolded in a zigzag manner, particularly partially overlapping, interfolded toweling folded "n" times. The method includes alternatingly cutting sections of toweling of equal length from a first continuously advancing web of material and from a second continuously advancing web of material, separating each of the cut sections of toweling in the direction of advancement to a specified length by extraction devices, reconducting together each of the cut sections of toweling and with a staggering device ordering a first sequence such that the cut sections of toweling have an overlap which is adjustable and equal, continuously folding with a pair of counter rotating folding rollers the first sequence of cut sections of toweling in a zigzag manner to a second sequence, and forming the second sequence of cut toweling folded in a zigzag manner into a folded stack.

  • Patent number: 5005816
    Abstract: An interfolder device for folding sheet material in a zig-zag manner which uses a pair of counter rotating rollers for receiving the sheet material and an elongated guide track disposed below the counter rotating rollers for receiving, supporting and conveying the sheet material as it is folded on the guide track. There is also provided a dynamic pressure means consisting of a vacuum that is coupled to the guide track by means of perforations formed in the guide track in order to apply a brake to the sheet material as it is supported and conveyed along the track during its folding process.

  • Patent number: 4994010
    Abstract: There is provided a method and apparatus for the attachment of clasps on letter envelopes incorporated into a machine for the manufacture of letter envelopes. The clasps, at the conclusion of the folding operation of the envelope machine, following the folding down of the lateral flaps of the envelope, are attached to the newly formed back sides of the letter envelopes. The apparatus is arranged for this purpose at the downstream end of a lateral folding mechanism of the envelope machine and includes a stationary opposing support plate.

  • Patent number: 4936816
    Abstract: A process and apparatus for opening the sealing flaps of a carton using drive elements for spreading or folding such sealing flaps open as required for packaging cartons having sealed bottoms. The boxes are inverted and lowered from a floating position with the bottom up and the sealing flaps hanging down. The flaps are placed on drive elements which move away from each other and in the flap opening direction. The box is then moved to a packaging area in the inverted position and lowered over the materials to be packaged.

  • Patent number: 4896480
    Abstract: A method and apparatus for placing a cover on a box is provided wherein the box cover is first lowered inclined and placed on the opening of a moving box such that its edge leading in the direction of motion grips across the edge of the opening of the box leading in the direction of motion, and its edge trailing in the direction of motion, which edge is inclined upwardly, remains supported. The box is moved or advanced in the direction of motion so that the box pulls the cover from the support supporting the trailing edge of the cover and the latter places itself on the opening of the box. Pressure is then applied to the cover from above in order to completely force the cover over the edges of the opening of the box.

  • 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.
