Description

Elektrischer RasierapparatElectric shaver
Die Erfindung bezieht sich auf einen elektrischen Rasierapparat mit einem Gehäuse, in welchem ein elektrischer Antrieb für die oszillierende Bewegung von Schneidmessern eines Scherkopfes angeordnet ist, wobei der Scherkopf wenigstens zwei miteinander zusammenwirkende Schneidelemente aufweist, welche relativ zueinander verschieblich angetrieben sind.The invention relates to an electric shaver with a housing in which an electric drive for the oscillating movement of cutting blades of a shaving head is arranged, wherein the shaving head has at least two interacting cutting elements which are displaceably driven relative to one another.
Ein Trockenrasierapparat der eingangs genannten Art ist beispielsweise aus der US-A 2,339,677 bekannt geworden. Bei dieser Ausbildung ist der aus einem Scherkopfrahmen, einem Obermesser und einem Untermesser gebildete Scherkopf auf einer oberen Ge- häusefläche eines Gehäuses quer zur Bewegungsrichtung eines in Längsrichtung oszillierend angetriebenen Untermesεers hin- und herbewegbar angeordnet. Der Antrieb erfolgt über einen Doppelexzenter. Eine weitere bekannte Ausbildung ist dem DE-U 17 11 665 zu entnehmen. Das Antriebselement des elektrischen Antriebs ist hier über Getriebeelemente, wie z.B. Zahnradgetriebe oder einen Doppelexzenter oder doppelarmige Hebel sowohl mit dem Untermesser als auch mit dem mit einem Obermesser ausgestatteten Scherkopf gekoppelt, um das Untermesser und zusätzlich den kompletten Scherkopf in Bewegung zu versetzen. Insgesamt wird bei einer derartigen Ausbildung dem Elektromotor eine hohe Leistung abverlangt, wodurch auch höhere Speieher1eistung und demzufolge eine geringere Anzahl an Rasuren pro Ladung der Speicherzellen beobachtet wird. Aus der DE-AI 36 31 120 ist es bekannt geworden, in eine hin- und hergehende Richtung angetriebene Massen, wie beispielsweise Exzenter und Kupplungselemente sowie Untermesser, mittels exzentrischer Schwunggewichte in ein dynamisches Gleichgewicht zu versetzen, um unerwünschte Schwingungen zu unterdrücken. Auch eine derartige Ausgestaltung erfordert eine Erhöhung der Leistungsabgäbe des elektrischen Antriebs . Schließ- lieh ist der DE 197 36 776 C2 eine Ausbildung zu entnehmen, bei welcher der Antriebsmotor elastisch gelagert ist und über Kuppelstangen mit einem ein Schermesser tragenden Scherkopfteil verbunden ist. Bei einer derartigen Ausbildung wird unmittelbar die Vibration des Motors zum Antrieb des Scherblatts zusätzlich zu dem vom Motor selbst abgeleiteten oszillierenden Antrieb der Schermesser abgeleitet.A dry shaver of the type mentioned is known for example from US-A 2,339,677. In this embodiment, the shaving head, which is formed from a shaving head frame, an upper knife and a lower knife, is arranged on an upper housing surface of a housing such that it can be moved back and forth transversely to the direction of movement of a lower knife driven in an oscillating manner in the longitudinal direction. The drive takes place via a double eccentric. Another known training can be found in DE-U 17 11 665. The drive element of the electric drive is coupled here via gear elements, such as a gear transmission or a double eccentric or double-armed lever, both to the lower knife and to the shaving head equipped with an upper knife, in order to set the lower knife and additionally the complete shaving head in motion. Overall, with such a design, the electric motor is required to have a high output, as a result of which higher storage output and, consequently, a lower number of shaves per charge of the storage cells is observed. From DE-AI 36 31 120 it has become known to move masses driven in a reciprocating direction, such as eccentrics and coupling elements as well as bottom knives, into dynamic equilibrium by means of eccentric balance weights in order to suppress unwanted vibrations. Such a configuration also requires an increase in the power output of the electric drive. Finally, DE 197 36 776 C2 shows an embodiment in which the drive motor is mounted elastically and via coupling rods with a shaving head part carrying a shaving knife connected is. With such a design, the vibration of the motor for driving the shaving blade is derived in addition to the oscillating drive of the shear blades derived from the motor itself.
Bei den bekannten Ausbildungen erfolgt somit der Antrieb eines Scherblatts relativ zu den oszillierenden Messern entweder in der Bewegungsrichtung der Oszillation oder im wesentlichen normal auf diese Oszillation, wodurch die Schneidleistung und die Sicherheit des Erfassens von schwer zu erfassenden Barthaaren nur unwesentlich beeinflußt wird.In the known designs, the shear blade is thus driven relative to the oscillating knives either in the direction of movement of the oscillation or essentially normally to this oscillation, as a result of which the cutting performance and the reliability of the detection of hard-to-grasp whiskers is only negligibly influenced.
Die Erfindung zielt nun darauf ab, eine Einrichtung der eingangs genannten Art zu schaffen, welche neben einer Erhöhung der Schneidleistung und einer Verringerung des Gleitwiderstandes des Scherblatts an der Haut auch die Sicherheit für das Erfassen von schwer zu erfassenden Barthaaren weiter erhöhen soll . Zur Lösung dieser Aufgabe besteht die erfindungsgemäße Ausbildung im wesentlichen darin, daß ein wenigstens ein Scherblatt tragender Teil des Scherkopfes um wenigstens eine von der Richtung der oszillierenden Bewegung der Schneidmesser verschiedene, sich in Richtung der längeren Achse des Gehäuses erstreckende Achse schwenkbar angelenkt und zu einer Schwenkbewegung um diese Achse angetrieben ist. Dadurch, daß die zusätzliche Bewegung des Scherblatts relativ zu den oszillierenden Schneidmessern nun weder in der Richtung der oszillierenden Bewegung noch in einer Richtung quer hierzu, sondern in einer Schwenkbewegung um eine zentrale Achse erfolgt, wird neben einer bedeutenden Verringerung des Gleitwiderstandes der Effekt beobachtet, daß durch die Schrägstellung relativ zur durch den Benutzer vorgegebene Bewegungsrichtung des Scherblatts bei der oszillierenden Bewegung um die zentrale Achse auch Haare sicher erfaßt werden, welche bei konventionellen Rasierapparaten kaum oder nur schwer zu erfassen sind. Neben einer deutlichen Verbesserung des Handhabungskom- forts wird somit die Schneidleistung gleichfalls verbessert. Dieser Effekt kann dadurch verbessert werden, daß der wenigstens ein Scherblatt tragende Teil des Scherkopfes um zwei einander kreuzende und von der Richtung der oszillierenden Bewegung der Schneidmesser verschiedene Achsen schwenkbar angelenkt ist.The invention now aims to provide a device of the type mentioned, which, in addition to increasing the cutting performance and reducing the sliding resistance of the shaving blade on the skin, is also intended to further increase the security for detecting hard-to-grasp whiskers. To achieve this object, the design according to the invention essentially consists in that a part of the shaving head which carries at least one shaving blade is pivotably articulated about at least one axis which differs in the direction of the oscillating movement of the cutting knives and extends in the direction of the longer axis of the housing and for a pivoting movement is driven about this axis. The fact that the additional movement of the shaving blade relative to the oscillating cutting knives now takes place neither in the direction of the oscillating movement nor in a direction transverse thereto, but in a pivoting movement about a central axis, in addition to a significant reduction in the sliding resistance, the effect is observed that due to the inclination relative to the direction of movement of the shaving blade specified by the user during the oscillating movement about the central axis, hair can also be reliably detected, which is difficult or difficult to detect in conventional shavers. In addition to a significant improvement in handling convenience, the cutting performance is also improved. This effect can be improved in that the part of the shaving head carrying at least one shaving blade is separated by two crossing axes different from the direction of the oscillating movement of the cutting knife is pivotally articulated.
Mit Vorteil ist die erfindungsgemäße Ausbildung so getroffen, daß die Lagerung des das Scherblatt tragenden Teiles des Scherkopfes als kardanische Lagerung, vorzugsweise als Kugelkopflagerung, ausgebildet ist. Eine derartige Kugelkopflagerung führt insgesamt zu einer wesentlich besseren Anpassung des Scherblatts an unregelmäßige Konturen der Haut und damit zu ei- ner verbesserten Schneidleistung, welche durch die oszillierende Schwenkbewegung noch weiter unterstützt wird.The design according to the invention is advantageously made such that the mounting of the part of the shaving head that carries the shaving blade is designed as a gimbal mounting, preferably as a ball-head mounting. Such a spherical head bearing leads overall to a much better adaptation of the shaving blade to irregular contours of the skin and thus to an improved cutting performance, which is further supported by the oscillating pivoting movement.
In besonders einfacher Weise kann der Schwenkantrieb des das Scherblatt tragenden Teiles des Scherkopfes über am Scherkopf oder am Gehäuse schwenkbar gelagerte Kipphebel von wenigstens einem oszillierenden Messer abgeleitet sein, wobei zur Vermittlung einer entsprechenden oszillierenden Schwenkbewegung um die zentrale Achse mit Vorteil die Ausgestaltung so getroffen ist, daß zwei Kipphebel, insbesondere an den einander gegenüber- liegenden Längsinnenwänden des Scherkopfes, angeordnet sind, welche jeweils mit einem der gegenläufig zueinander angetriebenen Schneidmesser bzw. Messerblöcken gekuppelt sind. Neben der durch den Benutzer aufgrund der Führung des Rasierapparates über die Haut üblicherweise vorgegebenen, im wesentlichen gerad- linigen Arbeitsrichtung erfolgt somit während der linearen Verschiebung gleichzeitig immer wieder eine Verschwenkung quer zur Verschieberichtung, wobei diese oszillierende Verschwenkung quer zur Verschieberichtung die Möglichkeit bietet, den Anpreßdruck weiter herabzusetzen und dennoch zuverlässig unregelmäßig abste- hende Barthaare zu schneiden. Durch die Anlenkung und Dimensionierung der Kipphebel kann ein relativ großer Hub der Oszillation der Schneidmesser in einen kleinen Schwenkwinkel untersetzt werden, sodaß keine nennenswerte Mehrbelastung des Antriebes eintritt .In a particularly simple manner, the pivot drive of the part of the shaving head which carries the shaving blade can be derived from at least one oscillating knife via rocker arms pivotably mounted on the shaving head or on the housing, the configuration advantageously being designed to convey a corresponding oscillating pivoting movement about the central axis, that two rocker arms are arranged, in particular on the opposing longitudinal inner walls of the shaving head, which are each coupled to one of the cutting knives or knife blocks driven in opposite directions. In addition to the essentially straight-line working direction, which is usually predetermined by the user due to the guiding of the shaving apparatus over the skin, a pivoting transversely to the direction of displacement takes place simultaneously during the linear displacement, this oscillating pivoting transverse to the direction of displacement offering the possibility of the contact pressure further reduce and still reliably cut irregularly protruding whiskers. Due to the articulation and dimensioning of the rocker arms, a relatively large stroke of the oscillation of the cutting knives can be reduced to a small swivel angle, so that there is no significant additional load on the drive.
In einer konstruktiv besonders einfachen Ausgestaltung kann die Ausbildung so getroffen sein, daß der oder die Kipphebel um die sich quer zur Oszillationsrichtung der Schneidmesser erstreckende Schwenkachse des Scherkopfes schwenkbar angelenkt ist (sind) . Durch die Verschwenkung des ganzen Schneidkopfes quer zur Oszillationsrichtung am Gehäuse selbst wird eine weitere Verbesserung der Anpassung der Position des Scherblatts relativ zur Haut bei unregelmäßiger Hautkontur gewährleistet, wobei diese Schwenkachse gleichzeitig in besonders einfacher Weise für die am Getriebe oszillierende Verschwenkung durch entsprechende Anordnung der Kipphebel herangezogen werden kann.In a structurally particularly simple embodiment, the training can be such that the rocker arm or rockers around pivot axis of the shaving head extending transversely to the direction of oscillation of the cutting knives is (are) pivotably articulated. The pivoting of the entire cutting head transversely to the direction of oscillation on the housing itself ensures a further improvement in the adjustment of the position of the cutting blade relative to the skin with an irregular skin contour, this pivot axis simultaneously being used in a particularly simple manner for the oscillating pivoting on the gearbox by appropriate arrangement of the rocker arms can be.
Mit Vorteil ist die Ausbildung so getroffen, daß der das Scherblatt tragende Teil des Scherkopfes an einem lösbar mit dem Gehäuse verbundenen Teil des Scherkopfes schwenkbar angelenkt ist. Auf diese Weise wird die freie bzw. gedämpfte Schwenkbarkeit des Scherblatts um eine quer zur oszillierenden Schwenkbewegung verlaufende Achse gewährleistet und eine Abnahme des gesamten Scherkopfes, beispielsweise zu Reinigungszwecken, erleichtert. In besonders vorteilhafter Weise ist die Ausbildung so getroffen, daß die sich in Richtung der längeren Achse des Ge- häuses erstreckende Schwenkachse außermittig nahe einer Längsinnenwand versetzt angeordnet ist, wodurch die Zone, in welcher die Durchbrechungen der Scherkopffolie bei zentraler Anordnung der Achse nur eine geringe Schwenkverlagerung erfahren, reduziert wird.The design is advantageously made such that the part of the shaving head which carries the shaving blade is pivotably articulated on a part of the shaving head which is detachably connected to the housing. In this way, the free or damped pivotability of the shaving blade about an axis extending transversely to the oscillating pivoting movement is ensured and removal of the entire shaving head, for example for cleaning purposes, is facilitated. In a particularly advantageous manner, the design is such that the pivot axis extending in the direction of the longer axis of the housing is offset off-center near a longitudinal inner wall, which means that the zone in which the openings in the shaving head film with a central arrangement of the axis is only slight Experience swivel displacement is reduced.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. In dieser zeigen Fig.l eine Vorderansicht des Kopfbereiches eines Rasierapparates, aus welcher sich die Verschwenkbarkeit um eine Achse ersehen läßt; Fig.2 eine Draufsicht auf die Ausbildung nach Fig.l mit der Darstellung der Schwenkbewegung um die zentrale Achse; Fig.3 einen Schnitt durch den Kopfbereich einer ersten Ausbildung des Schwenkkopfes; Fig.4 einen Schnitt analog der Fig.3 durch eine abgewandelte Ausbildung, Fig.5 eine weitere ab- gewandelte Ausbildung im Schnitt analog der Fig.3, Fig.6, 7 und 8 eine weitere Ausbildung in Drstellungen analog den Fig.l bis 3 mit einer Verschwenkbarkeit lediglich um die zentrale Achse, und Fig. 9 eine weitere Ausbildung im Schnitt analog der Fig.8.The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. 1 shows a front view of the head region of a shaving apparatus, from which the pivotability about an axis can be seen; 2 shows a top view of the design according to FIG. 1 with the representation of the pivoting movement about the central axis; 3 shows a section through the head region of a first embodiment of the swivel head; 4 shows a section analogous to FIG. 3 through a modified embodiment, FIG. 5 shows another modified embodiment in section analogous to FIG. 3, FIGS. 6, 7 and 8 shows another embodiment in positions analogous to FIGS 3 with a pivotability only about the central axis, and FIG. 9 shows a further embodiment in section analogous to FIG. 8.
In Fig.l ist das Gehäuse eines Rasierapparates mit 1 bezeichnet. An das Gehäuse ist ein zweiteiliger Scherkopf 2 angeschlossen, dessen Schwenkkopfunterteil 3 eine Schwenkachse 4 für die Verschwenkung eines ein Scherblatt 5 tragenden Kopfteiles 6 aufweist. Das Scherkopfunterteil weist hierbei eine dachförmige Oberkante auf, sodaß die freie Verschwenkbarkeit des Scherblatts 5 mit dem das Scherblatt 5 tragenden Scherkopfteil 6 in Richtung der Doppelpfeile 7 ermöglicht wird. In der Draufsicht nach Fig.2 ist eine zentrale Achse 8 ersichtlich, um welche der Scherkopfoberteil 6 mit dem Scherblatt 5 in Richtung der Doppelpfeile 9 verschwenkbar angelenkt ist.In Fig.l the housing of a shaver is designated 1. A two-part shaving head 2 is connected to the housing, the lower part 3 of which has a pivot axis 4 for pivoting a head part 6 which carries a shaving blade 5. The lower part of the shaving head in this case has a roof-shaped upper edge, so that the free pivotability of the shaving blade 5 with the shaving head part 6 carrying the shaving blade 5 in the direction of the double arrows 7 is made possible. In the top view according to FIG. 2, a central axis 8 can be seen, about which the upper shaving head part 6 is articulated with the shaving blade 5 in the direction of the double arrows 9.
Eine technische Ausgestaltung einer derartigen zentralen Schwenkachse 8 ergibt sich beispielsweise aus der Ausbildung nach Fig.3. In Fig.3 greift der das Scherblatt 5 tragende Scherkopfoberteil 6 über eine ballige Lagerung 10 in den Scherkopf- unterteil 3 ein, wobei diese ballige Lagerung 10 gleichzeitig die Verschwenkbarkeit des ScherkopfOberteils 6 um die in Fig.l ersichtliche Achse 4 gewährleistet. Durch die ballige Ausgestaltung dieser Lagerung ist aber auch eine Verschwenkung um die zentrale Achse 8 möglich. Der Antrieb der Schermesser 11 und 12, welche zu gegenläufiger oszillierender Bewegung angetrieben sind, wird von einem Motor 13 gebildet, welcher über einen Doppelexzenter 14 mit entsprechenden Kupplungsgliedern 15 bzw. 16 für den Antrieb der Messer 11 und 12 zusammenwirken. Vom Kuppelglied 15 wird über eine Lasche 17 die oszillierende Bewegung ab- gegriffen und auf einen Winkelhebel 18 übertragen, welcher um eine Schwenkachse 19 schwenkbar im Scherkopfunterteil 3 festgelegt ist. Bei der oszillierenden Bewegung des Kuppelgliedes 15 wird somit der Schwenkhebel 18 um die Achse 19 jeweils verschwenkt, wodurch der ScherkopfOberteil 6 um die Achse 8 in der balligen Lagerung 10 entsprechend der Darstellung in Fig.2 oszillierend verschwenkt werden kann, wobei der Antrieb unmittelbar vom Oszillationsantrieb eines Schermessers abgeleitet ist. Bei der Ausbildung nach den Fig.4 und 5 sind gleiche Bauteile wie in Fig.3 mit gleichen Bezugszeichen bezeichnet. Die Ausbildung nach Fig.4 unterscheidet sich von der Ausbildung nach Fig.3 lediglich dadurch, daß an zwei gegenüberliegenden Seiten des ScherkopfUnterteils 3 jeweils um Schwenkachsen 19 schwenkbar die Schwenkhebel 18 angelenkt sind. Da die Schwenkhebel 18 jeweils mit den parallel zueinander, aber gegenläufig angetriebenen Kuppelgliedern 15 und 16 über die entsprechenden Laschen 17 zusammenwirken, wird die Schwenkbewegung um die zentrale Achse 8 weiter unterstützt.A technical configuration of such a central pivot axis 8 results, for example, from the design according to FIG. 3. In FIG. 3, the upper shaving head part 6 carrying the shaving blade 5 engages in the lower shaving head part 3 via a spherical bearing 10, this spherical bearing 10 simultaneously ensuring that the upper shaving head part 6 can be pivoted about the axis 4 shown in FIG. Due to the spherical configuration of this mounting, pivoting about the central axis 8 is also possible. The drive of the shear knives 11 and 12, which are driven to reverse oscillating movement, is formed by a motor 13 which cooperate via a double eccentric 14 with corresponding coupling members 15 and 16 for driving the knives 11 and 12. The oscillating movement is tapped from the coupling element 15 via a tab 17 and transmitted to an angle lever 18, which is fixed in the lower shaving head part 3 so as to be pivotable about a pivot axis 19. With the oscillating movement of the coupling member 15, the pivot lever 18 is thus pivoted about the axis 19, whereby the shaving head upper part 6 can be pivoted about the axis 8 in the spherical bearing 10 as shown in FIG. 2, the drive directly from the oscillation drive a shear knife is derived. In the embodiment according to FIGS. 4 and 5, the same components as in FIG. 3 are identified by the same reference numerals. The embodiment according to FIG. 4 differs from the embodiment according to FIG. 3 only in that the pivot levers 18 are articulated on two opposite sides of the lower shear head part 3 so that they can pivot about pivot axes 19. Since the pivot levers 18 each cooperate with the coupling members 15 and 16, which are driven parallel to one another but in opposite directions, via the corresponding tabs 17, the pivot movement about the central axis 8 is further supported.
Bei der Ausbildung nach Fig.5 ist nun anstelle der balligen Lagerung eine elastische Lagerung durch die Dichtelemente 20 und 21 gebildet. Bei einer Schwenkbewegung um die zentrale Achse 8 aufgrund der Verschwenkung der Schwenkhebel 18 werden diese Dichtungen 20 und 21 entsprechend deformiert, sodaß auch hier zusätzlich zu der Verschwenkbarkeit um die Achse 4, wie sie in Fig.l ersichtlich ist, eine oszillierende und vom Antrieb abge- leitete Verschwenkung um die zentrale Achse 8 erfolgt.In the embodiment according to FIG. 5, an elastic mounting is now formed by the sealing elements 20 and 21 instead of the spherical mounting. With a pivoting movement about the central axis 8 due to the pivoting of the pivot lever 18, these seals 20 and 21 are deformed accordingly, so that in addition to the pivotability about the axis 4, as can be seen in Fig.l, an oscillating and abge from the drive - Guided pivoting about the central axis 8 takes place.
In den Fig.6, 7 und 8 ist eine Ausbildung dargestellt, bei welcher auf die Schwenkbarkeit um die Achse 4 in Richtung des Doppelpfeiles 7 verzichtet wird. Der Scherkopfoberteil 6 ist, wie in Fig.6 dargestellt, lediglich um die Achse 8 schwenkbar, wobei die Schwenkbewegung in einem Schlitz 23 geführt erfolgt. In diesen Schlitz 23 des Scherkopfunterteils 3 greift ein seitlich auskragender Fortsatz 24 ein, welcher bei Verschwenken der Schwenkhebel 18 im Inneren des Schlitzes 23 um die Achse 8 ver- schwenkbar ist. Die Schwenkbewegung erfolgt somit ausschließlich um die zentrale Achse 8 im Sinne des Doppelpfeils 9, wie dies in Fig.7 ersichtlich ist.6, 7 and 8, an embodiment is shown in which the pivotability about the axis 4 in the direction of the double arrow 7 is dispensed with. As shown in FIG. 6, the upper shaving head part 6 can only be pivoted about the axis 8, the pivoting movement taking place in a slot 23. A laterally projecting extension 24 engages in this slot 23 of the lower shaving head part 3 and can be pivoted about the axis 8 when the pivoting lever 18 is pivoted inside the slot 23. The pivoting movement thus takes place exclusively around the central axis 8 in the sense of the double arrow 9, as can be seen in FIG.
Bei der Darstellung nach Fig.9 ist eine weitere abgewandelte Ab- bildung ersichtlich, bei welcher gleichfalls auf eine Verschwenkbarkeit im Sinne des Doppelpfeils 7 verzichtet wird. Hier erfolgt die Anlenkung des Scherkopfoberteiles 6 am Scherkopfun- terteil 3 über ballige Lagerflächen 25, wobei durch Verschwenken der Schwenkhebel 18 wiederum ausschließlich eine Verschwenkung um die zentrale Achse 8 erfolgt. Die Darstellung nach den Fig.6, 7 und 8 entspricht hierbei im wesentlichen der Darstellung in den Fig.l, 2 und 3, wohingegen die Darstellung in Fig.9 den Schnitten nach Fig.3, 4, 5 und 8 entspricht. Die Bezugszeichen für gleichbleibende Teile wurden hierbei jeweils gleich gewählt.A further modified illustration can be seen in the representation according to FIG. 9, in which a pivotability in the sense of the double arrow 7 is also dispensed with. Here the upper part 6 of the shaving head is articulated to the terteil 3 on spherical bearing surfaces 25, wherein by pivoting the pivot lever 18 in turn, only a pivoting about the central axis 8 takes place. The representation according to FIGS. 6, 7 and 8 essentially corresponds to the representation in FIGS. 1, 2 and 3, whereas the representation in FIG. 9 corresponds to the sections according to FIGS. 3, 4, 5 and 8. The reference numerals for the same parts were chosen the same.
Die Achse 8 muß keineswegs zentral angeordnet sein und kann be- vorzugt, wie in Fig.7 angedeutet in Richtung des Pfeiles 26 versetzt nahe einer Längsinnenwand des Gehäuses angeordnet sein, wodurch die Anzahl der über einen nennenswerten Schwenkweg bewegten Scherkopffoliendurchbrechungen erhöht wird. The axis 8 does not have to be arranged centrally and can, as indicated in FIG. 7, be arranged offset in the direction of the arrow 26 near a longitudinal inner wall of the housing, as a result of which the number of shear head film openings moved over a significant pivoting path is increased.
