Abstract: The impression cylinder (2), which together with the cylinder (1) that prints the image, forms the printing nip, co-operates with two transfer cylinders (3, 4) which feed or remove the sheets, and has an essentially closed cylindrical circumferential surface, into which, at the beginning of each impression segment, a suction strip (5, 6) is inset to apply suction to the front edge of a sheet. The two transfer cylinders (3, 4) are similarly provided with suction strips (7, 8; 13, 14) which are arranged in good register with the suction strips (5, 6) of the impression cylinder (2), and moreover have dipping grippers (10, 12; 16, 18), which are located in gaps in the dipping strips. Sheet transfer to and from the impression cylinder (2) is effected by alternately switching on and off the suction air at the relevant suction strips.

Abstract: Each document (W1) is provided with a security feature in the form of a foil component (2) which is permanently attached to the document and cannot be changed without destroying it. Before the foil components are applied to the documents, they are provided with machine-readable image information which is variable from one foil component to another (3a, 4a). Once the foil component has been applied, the documents are passed through a reading device which reads the variable image information (3a, 4a) and controls a printer which applies a copy of this variable image information to the document outside the foil component. This can be in particular a combination of characters (7a) which is printed as part of a serial number (6a).

Abstract: The endless band is provided with print marks (D) at equal distances, this distance (r) corresponding to the circumference of the largest pack goods item (P) to be banded, plus an overlap. A strip-shaped glue coat (L) for closing the band loops (5a) is applied transversely to the longitudinal direction of the band at a constant predetermined distance (s) in front of each print mark (D). During banding, after the looping of the pack goods (P) the band movement is stopped when a print mark (D) is read by a print mark reader. At standstill, a glue coat (L) is located directly at the closing mechanism. While the free band end is retained, the endless band is retracted until the band loop (5a) surrounds the pack goods (P) with a specific tension. The closing of the band loop and the severance of the latter then take place.

Abstract: A procedure for producing a reference model for checking the printing quality of an image composed of at least two drawings starts with printed test sheets. The sheets are aligned so that drawings printed in a first printing are in register. The images are recorded, storing the densitometric pixel values which constitute the images in memory. The minimum value obtained is associated with each pixel and a model for the first drawing is obtained. The same procedure is followed for producing a second drawing and another model. The models thus obtained are recombined in order to form the reference model of the image to be checked.

Abstract: A net of parallel lines is generated with the aid of a computer. The ratio of the width to the spacing of two consecutive lines is equal to r.sub.o. The spacing and width of the lines are successively modulated such that their ratio is equal to r.sub.o. Subsequently, the straight lines can if so chosen be transformed into differently shaped lines or the width of the strokes can be altered in order to reproduce geometrical or artistic images.

Abstract: An automatic handling apparatus for handling stacking boards/stacking pallets comprising a carrying arm with an actuating mechanism (17-23) which operates the carrying arm in three different planes (X, Y, and Z) and about a rotational vertical axis (W). The stacking board is designed as a stackable pallet (1). This exhibits on its underside, on opposite side borders (1a, 1b), in each case two hollow feet (2) and in each case two hollow latching protuberances (4,5) with a smaller engagement depth than that of the feet. The feet (2,3) on each longitudinal border of the pallet are located opposite the hollow latching protuberances (4,5) on the other longitudinal border. In this manner, when a plurality of pallets are stacked one upon the other, depending on the orientation of the pallets, either a tightly packed storage stack can be produced. In the case of this storage stack, the feet of the pallet placed on top are sunk into the hollow feet of the pallet located thereabove.

Abstract: The rotary screen printing machine has a form cylinder (1) which carries a screen printing stencil (3), and an impression cylinder (2) having at least one cylinder pit (4), in which sheet grippers (5) are installed. In their closing position, the sheet grippers (5) do not project above the printing surface of the impression cylinder (2). Arranged inside the form cylinder (1) is an adjustable doctor (6) which can be controlled by an actuating mechanism (7, 8, 9) in such a way that, during a printing operation, the doctor (6) is pressed against the inside of the screen printing stencil (3), but is lifted off from this screen printing stencil when the open region of a cylinder pit (4) of the impression cylinder (2) passes the form cylinder (1).

Abstract: The stacking board is designed as a stackable pallet (1). This exhibits on its underside, on opposite side borders (1a, 1b), in each case two hollow feet (2) and in each case two hollow latching protuberances (4, 5) with a smaller engagement depth than that of the feet. The feet (2, 3) on each longitudinal border of the pallet are located opposite the hollow latching protuberances (4, 5) on the other longitudinal border. In this manner, when a plurality of pallets are stacked one upon the other, depending on the orientation of the pallets, a tightly packed storage stack can be produced. In the case of this storage stack, the feet of the pallet placed on top are sunk into the hollow feet of the pallet located thereabove. Alternatively, a working stack can be produced, in which case the feet of a pallet placed on top engage into the hollow latching protuberances of the pallet located therebeneath. Thus, adjacent pallets are spaced apart from one another by a predetermined distance.

Abstract: The draw roller is designed as a suction roller with a rotatable roller casing having orifices, and the material web loops around the draw roller along a circumferential portion. The internal suction-air supply connectable to a negative-pressure source opens out on the inner circumference of the roller casing and is designed so that a stationary suction surface of wedge-shaped form is obtained on the casing circumference. The wedge tip is directed opposite to the direction of rotation of the roller casing and is located at the start of said circumference portion in the roller center. The suction surface widens obliquely outwards on both sides with an increasing looping angle and, at the end of the circumferential portion, has a width corresponding to the total width of the material web.

Abstract: The apparatus has a distributor (11) with a straight conveying section (12), on which the N bundles of notes originating from a stack of sheets of notes are advanced one behind the other up to N predetermined bundle positions. Fitted underneath the conveying section (12), having an adjustable base (13), are N magazines in the form of vertical compartments which are located vertically underneath the bundle positions. Once all N bundle positions on the conveying section (12) are occupied by bundles, the base (13) is swung down, so that all N bundles can drop simultaneously into the N magazine compartments. After closing of the base, the next N bundles pass on the conveying section (12) into their bundle positions and, after opening of the base, can drop into the magazines as the second layer.

Abstract: The installation for quality control of printed sheets (1) comprises means (8-13) for transferring said sheets, and cameras (2, 4, 6) for checking the print quality. The transfer means (8-13) are designed to transport the sheets in a plane and to allow the print quality of each of the faces of the sheet to be checked as well as a quality check using transparency to be carried out in succession and in a single pass. The means for checking each face are two cameras (2, 3) located on either side of said plane at two offset locations, the transfer means being designed to leave an open window at the side of each camera. A third camera (6) carries out the check using transparency.

Abstract: An image processing apparatus includes a data acquisition stage for acquiring data representative of several spatially separated regions of a sample. The apparatus also includes data storage means for storing reference data corresponding to the sample data. The two sets of data are compiled and analyzed to determine if the sample is shifted from a nominal position.

Abstract: A sequence of H sheets of notes, for example 100 sheets, is first of all checked for misprints, and the note positions having misprints of each sheet are stored in a computer. The sheets of this sequence then pass a numbering machine (4), which has freely programmable numbering units, which are controlled by the computer. In this case, the numbering takes place in such a way that all the satisfactory note prints within the sequence of sheets, excluding the misprints, receive a consecutive sequence of numbers, the sequence of numbers of H notes in one and the same note position being the continuation of the sequence of numbers of the H notes in a neighboring note position. The next sequence of H sheets receives the subsequent sequence of numbers.

Abstract: The printing unit has two cooperating cylinders (1, 4) which form the printing nip and which have printing saddles (2, 5) separated by cylinder pits (3, 6). The paper web (7) passing through the printing nip is transported in the pilgrim-step mode, in order to print formats adjoining one another. The two cylinders (1, 4) are angularly adjustable relative to one another, in respect of the position of their printing saddles (2, 5) cooperating in the printing nip, in a manner offset by the amount of a circumferential distance which is approximately equal to the difference between the circumferential length (S) of a printing saddle and the circumferential length (B) of a printing image. The impression zone is therefore only approximately as large as the printing image, and the impression-free zone available for retracting the paper web is correspondingly enlarged.

Abstract: The web-fed printing machine has two cylinders (2, 3) which form the nip, a paper-web-directing device (10) with an infeed roller (14) and a discharge roller (15), which are arranged adjustably on both sides of the nip (S), and an upstream web-feeding device (20), which likewise exhibits an infeed roller (22) and a discharge roller (23). In order to align the paper web, the web-directing device (10) can be displaced in a plane running through the axes of the rollers, and can be adjusted as a function of the signals from web-edge sensors (16, 17) such that it can be adjusted in the direction of the axes of rotation of the rollers and can be pivoted into an oblique position. The web-feeding device (20) can be pivoted about a stationary spindle (24) and is connected mechanically to the web-directing device.

Abstract: An image acquisition system includes a transport mechanism for transporting sheets of objects past a sensor. The sensor scans the objects and generates data streams which are scaled by a multiplier to compensate for the speed variation of the transport mechanism. At speeds much lower than a nominal speed, the scanning rate of the sensor is increased to generate several data streams for each scanned line, which are then combined in a single speed corrected signal stream for further processing.

Abstract: The device has a sheet-transfer cylinder (2) with a movable setting plate (3) which bears the sheet grippers (4) and whose lateral ends are individually adjustable during each revolution of the transfer cylinder (2) with the aid in each case of a roller lever (9) in the circumferential direction in such a way that the sheet transferred to the impression cylinder is in a position which corresponds to the precise printing register. For this purpose, each roller lever (9) mounted movably on the transfer cylinder (2) is guided in a guide path (15c), surrounding the cylinder axis (1) in an annular manner, of an actuator (15, 16) which is suspended pivotably above the cylinder axis (1). Said actuator is provided with individually adjustable stops (19a, 19b) which, by interaction with peripheral cams (24a to 24d) pivot the relevant actuator (15, 16) by a predeterminable amount during each revolution of the transfer cylinder (2) and thus displace the relevant end of the setting plate (3).

Abstract: The counting station has a transporting section (2b), on which the banderoled packs of notes (P) are moved at certain intervals uniformally past the rotating counting disk (1a, 1a') of a note-counting device (1, 1') fixedly installed on this transporting section. Downstream of the transporting section (2b) there is a diverter (9) with two further transporting sections (2c, 2d), of which one receives packs of notes having the correct number of notes of value and the other receives packs of notes having the incorrect number of notes of value.
