Ein Prägezylinder 1, insbesondere ein Heißprägezylinder 1 zum rotativen Heißprägen von Mustern von einer Folie auf einen Papierbogen oder eine Papierbahn in einer Fo l i enprägemaschi ne ist mit mindestens einem Haltering 2 zur Aufnahme von Prägestempeln 3 versehen. In axialer Richtung des Heißprägezylinders 1 gesehen, können eine Mehrzahl dieser Halteringe 2 nebeneinander auf dem Heißprägezylinder 1 angeordnet sein. Der Haltering 2 weist in Umfangsrichtung des Heißprägezylinders 1 verlaufend im Querschnitt ein liegendes H-Profi l auf. Ein Innendurchmesser d2, z. B. d2 = 550 mm, des Halteringes 2 ist auf einen Außendurchmesser D1, z. B. D1 = 600 mm, des Heißprägezylinders 1 angepaßt, so daß der Haltering 2 bei unbeheiztem Heißprägezyl1nder 1 in axialer Richtung verschi ebbar ist.An embossing cylinder 1, in particular a hot embossing cylinder 1 for the rotary hot embossing of patterns from a film onto a sheet of paper or a paper web in a foil embossing machine is provided with at least one retaining ring 2 for receiving embossing dies 3. Seen in the axial direction of the hot stamping cylinder 1, a plurality of these retaining rings 2 can be arranged next to one another on the hot stamping cylinder 1. The retaining ring 2 has a horizontal H profile running in cross section in the circumferential direction of the hot stamping cylinder 1. An inner diameter d2, e.g. B. d2 = 550 mm, the retaining ring 2 is on an outer diameter D1, z. B. D1 = 600 mm, des Hot stamping cylinder 1 adapted so that the retaining ring 2 can be moved in the axial direction when the hot stamping cylinder 1 is not heated.
In einer U-fÖrmigen Nut 6 des Halteringes 2, die einer Mantelfläche 4 des Heißprägezylinders 1 zugewandt Ist, sind elektrisch beheizbare Heizelemente 7 angebracht. Eine nach außen weisende U-förmige Nut 8 des Halterings 2 wird von zwei parallel gegenüberliegenden Seitenwänden 9, 11 und einer Grundfläche 12 begrenzt. Diese Nut 8 weist in ihrem Querschnitt eine Tiefe tδ, z. B. t8 = 12,5 mm, und eine Breite bδ, z. B. bδ = 33 mm, auf und ist im vorliegenden Beispiel endlos umlaufend ausgebi Idet .In a U-shaped groove 6 of the retaining ring 2, which faces a lateral surface 4 of the hot stamping cylinder 1, electrically heated heating elements 7 are attached. An outwardly facing U-shaped groove 8 of the retaining ring 2 is delimited by two parallel opposite side walls 9, 11 and a base area 12. This groove 8 has a depth tδ, z. B. t8 = 12.5 mm, and a width bδ, z. B. bδ = 33 mm, and in the present example is endlessly trained idi.
In beiden Seitenwänden 9, 11 dieser Nut δ sind eine Vielzahl von achsparallel zum Heißprägezylinder 1, senkrecht durch die Seitenwände 9, 11 verlaufender Bohrungen 13 mit einem Durchmesser d13, z. B. d13 = 6 mm, eingebracht. Diese Bohrung 13 setzt sich jeweils in einer Gewindebohrung 14 fort. In die Gewindebohrung 14 ist eine Gewindeschraube 16 eingeschraubt. Die Gewindeschrauben 16 in der linken Seitenwand 9 drücken jeweils direkt auf ein erstes Ende eines Druckstückes 17, z. B. eines Zylinderstiftes 17. In der rechten Seitenwand 11 ist jeweils zwischen Gewindeschraube 16 und einem Druckstück 18, z. B. einem Zylinderstift 18 eine Druckfeder 19, z. B. in Form eines Paketes von Te l Ierfedern, angeordnet. Ein in die U-fδrmige Nut 8 ragendes Ende des Zylinderstiftes 17, 1δ ist keilförmig ausgebi ldet, z. B. mit einer schräg verlaufenden Klemmfläche 21 versehen. Diese Klemmfläche 21 schließt mit einer Längsachse 22 des Zy 11 nderst1 ftes 17, 1β einen Winkel alpha, z. B. alpha « 45°, ein. Anstelle dieser so ausgebi ldeten Klemmfläche 21 sind auch andere Formen möglich, wie z. B. ein kegelförmiges Ende des Zylinderstiftes 17, 1δ.In both side walls 9, 11 of this groove δ are a plurality of axially parallel to the hot stamping cylinder 1, perpendicular through the side walls 9, 11 bores 13 with a diameter d13, z. B. d13 = 6 mm. This bore 13 continues in a threaded bore 14. A threaded screw 16 is screwed into the threaded bore 14. The threaded screws 16 in the left side wall 9 each press directly onto a first end of a pressure piece 17, e.g. B. a cylindrical pin 17. In the right side wall 11 is between the threaded screw 16 and a pressure piece 18, z. B. a cylinder pin 18 a compression spring 19, for. B. in the form of a package of Te l Ierfedern arranged. An in the U-shaped groove 8 protruding end of the cylindrical pin 17, 1δ is wedge-shaped, z. B. with an oblique provided clamping surface 21. This clamping surface 21 closes with a longitudinal axis 22 of the Zy 11 nderst1 ftes 17, 1β an angle alpha, z. B. alpha «45 °, a. Instead of this clamping surface 21 thus formed, other shapes are also possible, such as, for. B. a conical end of the cylindrical pin 17, 1δ.
In der U-förmigen Nut δ ist mindestens ein Prägestempel 3 angeordnet. Dieser Prägestempel 3 weist eine Höhe h3, z. B. h3 = 12,5 mm, und eine Breite b3, z. B. b3 = 30 mm, auf. Die Höhe h3 des Prägestempels 3 Ist größer als die Tiefe tδ der U-förmigen Nut δ und die Breite b3 des Prägestempels ist im Ausführungsbeispiel kleiner als die Breite bδ der U-förmigen Nut δ. Es ist aber auch möglich, daß die Höhe h3 und die Tiefe tδ gleich sind. An seiner radial nach außen weisenden Fläche 23 ist der Prägestempel 3 mit einer oder mehreren erhabenen übe rt ragungs f lache (n) 24 versehen. Diese übert ragungs f lache 24 ist im vorliegenden Beispiel als gleichseitiges Fünfeck ausgeführt. An beiden Seitenflächen 26, 27 sind in Umfangsrichtung des Halteringes 2 verlaufende, auf eine Krümmung des Halteringes 2 angepaßte Klemmflächen 28, 29 angeordnet. Diese in Umfangsrichtung gekrümmten Klemmflächen 2δ, 29 schließen mit der entsprechenden Seitenfläche 26, 27 einen Winkel beta, z. B. beta = 45°, ein. Eine Grundfläche 31 des Prägestempels 3 liegt auf der Grundfläche 12 der U-förmigen Nut δ auf. Diese Grundfläche 31 ist auf die Krümmung der Grundfläche 12 der U-förmigen Nut δ des Prägestempels 3 angepaßt und deshalb leicht gewölbt. Durch die Anordnung von den beiden achsensymmetrisch angeordneten Klemmflächen 28, 29 und der Grundfläche 31 Ist 1m unteren Bereich ein Querschnitt des Prägestempels 3 annähernd schwa Ibenschwanzförmi g. Somit weist der Prägestempel 3 eine entsprechend der Krümmung des Kalteringes 2 gekrümmte schwalbenschwanzartige Führung 32 auf. Im vorliegenden Ausführungsbeispiel sind vier Druckstücke 17, 18 angeordnet, die mit den Klemmflächen 28, 29 dieser schwalbenschwanzartigen Führung 32 zusammenwirken. Dabei wirken die beiden in der linken Seitenwand 9 ungefedert angeordneten Druckstücke 1δ als einstellbare Anschläge. Die beiden in der rechten Seitenwand 11 gefedert angeordneten Druckstücke 17 drücken den Prägestempel 3 gegen die beiden linken Druckstücke 1δ. Dabei entsteht mittels der unter den Winkeln alpha und beta angeordneten Klemmflächen 2δ, 29 bzw. Druckstücken 17, 1δ eine Kraft komponente in radialer Richtung, die den Prägestempel 3 auf die Grundfläche 12 der U-förmigen Nut δ drückt. Zur Ausrichtung des Prägestempels 3 in Umfangsrichtung ist beispielsweise in der Grundfläche 12 der U-förmigen Nut 8 eine Bohrung 33 eingebracht, in die ein als Anschlag dienender Stift eingebracht werden kann. Auch ist es möglich den Haltering in Umfangsrichtung mit einer Zahlenskala zu versehen.At least one stamp 3 is arranged in the U-shaped groove δ. This stamp 3 has a height h3, z. B. h3 = 12.5 mm, and a width b3, z. B. b3 = 30 mm. The height h3 of the die 3 is greater than the depth tδ of the U-shaped groove δ and the width b3 of the die is smaller than the width bδ of the U-shaped groove δ in the exemplary embodiment. But it is also possible that the height h3 and the depth tδ are the same. The embossing die 3 is provided on its radially outward-facing surface 23 with one or more raised protruding surfaces 24. This transmission surface 24 is designed as an equilateral pentagon in the present example. Clamping surfaces 28, 29, which extend in the circumferential direction of the holding ring 2 and are adapted to a curvature of the holding ring 2, are arranged on both side surfaces 26, 27. These circumferentially curved clamping surfaces 2δ, 29 close with the corresponding side surface 26, 27 an angle beta, z. B. beta = 45 °. A base surface 31 of the die 3 lies on the base surface 12 of the U-shaped groove δ. This base area 31 is on the curvature of the base area 12 adapted to the U-shaped groove δ of the die 3 and therefore slightly curved. Due to the arrangement of the two axially symmetrically arranged clamping surfaces 28, 29 and the base surface 31, a cross section of the embossing die 3 is approximately black in the lower region. The stamping die 3 thus has a dovetail-like guide 32 which is curved in accordance with the curvature of the cold ring 2. In the present exemplary embodiment, four pressure pieces 17, 18 are arranged, which cooperate with the clamping surfaces 28, 29 of this dovetail-like guide 32. The two pressure pieces 1δ arranged without spring in the left side wall 9 act as adjustable stops. The two pressure pieces 17, which are arranged in a spring-loaded manner in the right side wall 11, press the die 3 against the two left pressure pieces 1δ. This creates a force component in the radial direction by means of the clamping surfaces 2δ, 29 or pressure pieces 17, 1δ arranged at the angles alpha and beta, which presses the embossing die 3 onto the base surface 12 of the U-shaped groove δ. To align the embossing die 3 in the circumferential direction, for example, a bore 33 is made in the base 12 of the U-shaped groove 8, into which a pin serving as a stop can be inserted. It is also possible to provide the retaining ring with a number scale in the circumferential direction.
Zur Ausrichtung in Umfangsrichtung werden die beiden rechten Gewindeschrauben 16 gelöst, bis die Druckfedern 19 entspannt sind. Der Prägestempel 3 kann nun 1n Umfangsrichtung in die gewünschte Position verschoben werden. Die beiden Gewindeschrauben 16 werden anschließend wieder eingeschraubt, bis die Druckfedern 19 eine festgelegte Vorspannkraft auf die Druckstücke 17, 1δ erzeugen. Der Prägestempel 3 wird so an die gegenüberliegenden Druckstücke 17, 18 angepreßt. Soll nun der Prägestempel 3 in axialer Richtung des Heißprägezylinders 1 verschoben werden, werden die beiden Gewindeschrauben 16 der ungefederten Druckstücke 17 gleichmäßig verdreht. Gegebenenfalls wird die Vorspannkraft der Druckfedern 19 der gefederten, gegenüberliegenden Druckstücke 18 nachreguliert. For alignment in the circumferential direction, the two right threaded screws 16 loosened until the compression springs 19 are relaxed. The stamp 3 can now be moved in the circumferential direction into the desired position. The two threaded screws 16 are then screwed in again until the compression springs 19 generate a predetermined pretensioning force on the pressure pieces 17, 1δ. The embossing stamp 3 is pressed against the opposing pressure pieces 17, 18. If the stamping die 3 is now to be moved in the axial direction of the hot stamping cylinder 1, the two threaded screws 16 of the unsprung pressure pieces 17 are rotated uniformly. If necessary, the biasing force of the compression springs 19 of the sprung, opposing pressure pieces 18 is readjusted.
