Abstract: The device for satinizing and embossing metallized or surface-treated packaging foils comprises three embossing rolls, all three embossing rolls cooperating with one another and the packaging foil being capable of being passed under pressure between the first and the second and between the first and the third embossing rolls in order to produce a satin-finish and a pattern. The first, driven embossing roll has a tooth array composed of individual teeth that are arranged in a homogenous grid, and the other two embossing rolls each have a surface structure that differs from that of the first embossing roll. At least one of the additional embossing rolls has structural elements that are arranged individually or in groups but not in the same grid as on the first roll, the structural element being composed of individual teeth and being arranged circularly on the embossing roll. Such an arrangement provides an effective breaking of the paper substrate of the foil and thus a surface having improved properties.

Abstract: In the method for the authentication of identification features that are embossed on a packaging foil together with satin-finishing and the embossing of logos, a number of identification features is embossed on-line as a pattern and read by a suitable apparatus and evaluated by means of an image evaluation method. The embossing device (1) suitable therefor includes at least two embossing rollers (2, 3, 15), a reading unit, and an evaluating unit, one of the embossing rollers (2) being driven by the motor drive mechanism (5) and having individual teeth (8) of which a number of teeth for embossing identification features have a different shape, height, or surface structure while the remaining teeth serve for satin-finishing, and one of the mating rollers (3) being provided with circumferential rings (10). Such a method and such a device allow a relatively simpler embossing device with relatively lower requirements with regard to the embossing quality than in methods of the prior art.

Abstract: The device for satinizing and embossing flat materials comprises an embossing roll and at least one mating roll, said rolls being connected to a driving system and adapted to be driven individually or in common and to be resiliently pressed against one another while the individual teeth are flattened, and the embossing teeth being designed such as to produce in the corresponding locations of said flat material during its passage embossed marks whose appearance varies according to the viewing angle of the observer and/or the kind and/or the position of the lighting source, the embossing teeth which produce said variable marks having a different geometrical shape and/or surface than the satinizing teeth intended for satinizing. To this end, the surfaces of said embossing teeth and/or portions of the tooth space bottom are provided with microstructures. These microstructures allow producing largely forgery-proof marks which may furthermore provide a very decorative effect.

Abstract: The invention relates to a device for embossing and/or glazing films. The device for embossing includes a first and second embossing roll, through which flat material can be fed under pressure, in order to create a pattern. An additional embossing roll is connected downstream of the second embossing roll, this additional embossing roll interacting with the first or preceding embossing roll. The patterned flat material may be fed between these embossing rolls, in order to be embossed again with essentially the same pattern. In a simplified embodiment, only a total of two rolls are used. In order to achieve as precise an embossing as possible, with special effects, the first driven embossing roll is provided with teeth, while at least one other embossing roll comprises rings or longitudinal ribs, or is smooth.

Abstract: A point-of-use liquid application device adapted to be selectively adhered to a plant and activated by the fingers of a human hand. Upon activation a liquid solution is released from a liquid-tight fluid reservoir and is delivered to an individual predetermined plant. The device incorporates a primary substrate with at least one adhesive area; a backing substrate releasably covering the at least one adhesive area; a liquid-tight fluid reservoir containing a liquid solution at least partially attached to the primary substrate; and a dispersion strip in contact with a portion of the liquid-tight fluid reservoir. The design of the device facilitates attachment to the plant by wrapping the primary substrate around a portion of the plant and attaching a portion of the at least one adhesive area to a portion of the primary substrate. The liquid solution may be an herbicide and may include an absorption enhancement agent.

Abstract: A device for satinizing and simultaneously embossing flat materials that includes at least two embossing rolls. One roll is connected to a driving system. The rolls are adapted to be driven individually or in common and are adapted to be resiliently applied against each other. Pyramidal or conical teeth of the rolls have flattened tips. The teeth of at least one roll are shaped so as to produce embossed signs in corresponding locations of the passing flat material so that the appearance of the embossed signs changes according to at least one of a viewing angle of the observer, a kind, and the position of the lighting source.

Abstract: The device for the satining and embossing of innerliners for tobacco, food and pharmaceutical products, comprises a roll with a pin up configuration of the teeth and a roll with a pin down configuration of corresponding recesses. At only one of the rolls the part corresponding to the logo has been worked on to form the logo, whereas the recesses, respectively the teeth, on the other roll have not been altered in their shape. This allows a lower cost production of the rolls since no matching pairs of rolls have to be produced and exchanged for wear or changing logo.

Abstract: The apparatus for satin-finishing and embossing flat material comprises a first toothed roller and at least a second toothed roller, with the rollers being disposed in such a way that a tooth each of a roller engages between four teeth of the other roller. One of the rollers comprises at least a microstructure and the other roller is provided at the respective place with a counter-pressure surface. The microstructure is applied to a hard surface layer which is applied via an intermediate layer to the roller surface. The method is especially advantageous if a film with a thermoplastic intermediate layer is used. Such an apparatus allows embossing logos with microstructures at all desired locations of the rollers, thus offering a high amount of security against falsification and a large variety of design features.

Abstract: The invention relates to a device for embossing and/or glazing films. Said device comprises at least one first and one second embossing roll, through which the flat material can be fed under pressure, in order to create a pattern. At least one additional embossing roll (4) is connected downstream of the second embossing roll (3), said additional embossing roll interacting with the first (2) or preceding (3) embossing roll. The patterned flat material (6) can be fed between these embossing rolls, in order to be embossed again with essentially the same pattern. In a simplified embodiment, only a total of two rolls (2, 4) is used. In order to achieve as precise an embossing as possible, with special effects, the first driven embossing roll (2) is provided with teeth (8), while at least one other embossing roll (3, 4, 20) comprises rings (10) or longitudinal ribs (12), or is smooth.

Abstract: The device for embossing and/or calendering foils comprises at least one first and one second embossing roll between the flat material is passed under pressure in order to produce a pattern. The second embossing roll is followed by at least another embossing roll which cooperates with the first or the preceding embossing roll and between which the patterned flat material is passed in order to receive essentially the same pattern in a re-embossing procedure. In the case of complex treatments, it is advantageous to synchronize the embossing rolls. Particularly in the case of paper having a thin metallization, the following additional embossing roll which re-embosses the pattern allows to avoid higher contact pressures causing increased wear, and a substantially improved folding behavior is obtained.

Abstract: The invention relates to a device for embossing and/or satin-finishing a flat material, comprising at least two embossing rolls that are linked with a drive and that can be driven individually or jointly. The rolls can be elastically pressed against each other and the pyramidal teeth of the rolls have a flattened tip. In order to produce an embossed structure with variable optical effects the teeth (T2) of at least one of the rolls are adapted to provide the flat material, especially the metallized packaging foil, with a sign (L) whose aspect varies depending on the visual angle of the viewer (O) and/or kind and/or location of the source of light (LS). These teeth (T2) have, for example, a height that is inferior to that of the remaining teeth (T1). The inventive device allows not only production of special effects by embossing but also production of security features that are especially forgery-proof.

Abstract: The embossing rolls of embossing devices serving for the treatment of two-dimensionally extending materials, preferably in the packaging industry, may be made exchangeable if they are disposed in suitable interchangeable units. An interchangeable unit may e.g. take the form of a sleeve having its ends provided with fitting surfaces. The mount of an embossing device comprises corresponding seats which are very precisely adapted to the actual interchangeable unit. In the inserted condition, i.e. when the fitting surfaces of the retaining elements are inserted in the associated seats, the embossing roll contained in an exchangeable unit is thus placed in its operational position without requiring any further adjusting operations. Particularly the driven embossing roll of such an embossing device is thus substantially less complicated to exchange, thereby allowing quick maintenance and production changeovers.

Abstract: The embossing process is effected between a pair of embossing rollers provided with toothings of the same kind which comprise rows of pyramidal teeth extending in the axial and the circumferential directions. Compared to the theoretical pyramid shape, the heads of the teeth are flattened while the edges of the pyramids are cut. The rollers, which are mutually displaceable in the axial direction, are thus able to catch in a stable mutual position of maximum penetration and to remain in this position in operation. This allows a safe mutual synchronization of the rollers and an optimal embossing of any kind of materials, especially of paper foils.

Abstract: Two rolls, more particularly embossing rolls are provided which are pressed against each other by pneumatic cylinders for the purpose of fashioning a flat material passing between the rolls. The ends of one of the roll axles are journalled in slides which are actuatable by the cylinders in such a manner as to be deflectable in the pressure direction and in the travelling direction of the material. The elastically suspended roll is thus capable of automatically adjusting itself in such a manner that the axles of the two rolls can adjust to irregularities of the flat material and thus allow a disturbance-free and qualitatively optimal treatment of the material.

Abstract: This process consists in raising the temperature of a probe immersed in the fluid to a temperature threshold corresponding to an electric resistance (R.sub.1), in measuring at least a second temperature threshold corresponding to a second resistance (R.sub.2, R.sub.3), in measuring the time elapsed between these different thresholds and in calculating a parameter of the fluid linked to the thermal transfer between the probe and the fluid, i.e., the temperature, the velocity, the viscosity, the density, the specific heat or the thermal conductivity.
