Description

Die Erfindung betrifft eine Schneide- und Wickelvorrichtung für Folienstreifen, bei der im Anschluß an eine Längsschneide-Station zum Schneiden von Folienstreifen aus einer Bahn die im wesentlichen in einer horizontalen Reihe angeordneten Folienstreifen zu einer Aufspul- beziehungsweise Wickeleinheit geführt werden. Sie betrifft ferner ein Verfahren zum Spulen- beziehungsweise Wickelkernwechsel beim Aufwickeln der Folienstreifen.The invention relates to a cutting and winding device for film strips, in which, following a slitting station for cutting film strips from a web, the film strips arranged essentially in a horizontal row are guided to a winding or winding unit. It also relates to a method for changing the spool or winding core when winding up the film strips.

Bei den bekannten Anlagen zur Herstellung von Folienstreifen wird eine fortlaufende Folienbahn von gleichbleibender Breite zu einzelnen Folienstreifen zerschnitten. Dies geschieht mit Hilfe einer senkrecht zur Bahnlaufrichtung angeordneten Reihe ortsfester Trennmesser, die zueinander gleichen Abstand haben und mit ihren gegen die Bahnbewegung gerichteten Schneiden in die Bahn hineinragen. Die fertigen Folienstreifen werden dann einzeln auf einer Aufspuleinheit auf Spulen oder flanschlose Wickelkerne aufgewickelt. Dabei können die einzelnen Aufspuleinheiten in Laufrichtung der Folienstreifen in einer Reihe hintereinander oder nebeneinander angeordnet oder bei einer größeren Zahl aufzuwickelnder Folienstreifen können auch mehrere Reihen von Aufspuleinheiten in Etagen übereinander angeordnet sein.In the known systems for the production of film strips, a continuous film web of constant width is cut into individual film strips. This is done with the help of a row of stationary separating knives arranged perpendicular to the web running direction, which have the same distance to each other and protrude into the web with their cutting edges directed against the web movement. The finished film strips are then individually wound onto spools or flangeless winding cores on a winding unit. The individual winding units can be arranged in a row one behind the other or next to one another in the running direction of the film strips, or if there are a large number of film strips to be wound up, several rows of winding units can also be arranged one above the other in tiers.

Wenn die Spulen beziehungsweise Bandwickel ihren vorgesehenen Durchmesser erreicht haben, wird ein Spulenwechsel erforderlich. Hierzu werden die einzelnen Folienstreifen von ihren jeweiligen Spulen abgetrennt. Dann wird die volle Spule abgenommen und ein Leerkern aufgesteckt, worauf der jeweilige Folienstreifen zum weiteren Aufwickeln wieder angelegt wird. Wesentliche Nachteile dieser Art des Spulenwechselvorganges ist die dabei entstehende Abfallmenge sowie die erhebliche Umrüst- und Wechselzeit.When the reels or tape windings have reached their intended diameter, a reel change is required. For this, the individual film strips separated from their respective coils. Then the full spool is removed and an empty core is plugged on, whereupon the respective film strip is put on again for further winding. The main disadvantages of this type of bobbin changing process are the amount of waste generated and the considerable changeover and changing time.

Aus zahlreichen Veröffentlichungen sind Verfahren beziehungsweise Vorrichtungen bekannt, die diese Nachteile beseitigen sollen. So wird in der DE 34 14 636 ein Verfahren zum Spulenwechsel beschrieben, bei dem die Abfallmenge, welche beim Aufspulen mehrerer Reihen von Aufspuleinheiten, welche hintereinander angeordnet sind reduziert werden soll. Aus der DE 34 18 741 ist eine Schneid- und Wickelvorrichtung bekannt, bei der jeweils die getrennten Folienstreifen auf fest mit einer Wickelwelle verbundene Kerne aufgewickelt werden und wobei jeweils vier Wickelwellen innerhalb eines Wickelsterns vorhanden sind, welche axial verschiebbar sind und einer Entstückungs- sowie einer Bestückungseinrichtung zugeführt werden können, welche gleichzeitig die Entstückung einer Wickelwelle von Wickelkernen und die Bestückung einer anderen Welle mit neuen Wickelkernen besorgt. Aus der DE 23 46 330 ist eine Rollenschneid- und Wickelmaschine für Folienstreifen bekannt, bei der im Anschluß an eine Längsschneidestation zum Schneiden von Bahnstreifen aus einer Bahn eine Trennstation zum Auseinanderführen jeweils benachbarter Bahnstreifen zu gesonderten Wickelachsen vorgesehen ist, wobei in Längsnuten jeder Wickelachse Ausrichtkämme mit radialen Ausrichtkanten verstellbar angeordnet sind, welche die Wickelhülsen positionieren. Aus der DE 23 65 606 ist eine entsprechende Vorrichtung bekannt, bei der im Anschluß an eine Längsschneidestation zum Schneiden von Folienstreifen aus einer Bahn die Folien auf einzelne Wickelkerne geführt werden und wobei jedem Wickelkern eine auf dem Umfang des Wickels aufliegende Antriebsrolle zugeordnet ist.Methods and devices are known from numerous publications which are intended to eliminate these disadvantages. For example, DE 34 14 636 describes a method for changing bobbins in which the amount of waste which is to be reduced when winding up several rows of winding units which are arranged one behind the other. From DE 34 18 741 a cutting and winding device is known in which the separate film strips are wound onto cores which are fixedly connected to a winding shaft, and four winding shafts are present within a winding star, which are axially displaceable and one denaturing and one Assembly device can be supplied, which simultaneously takes care of the denaturing of a winding shaft of winding cores and the equipping of another shaft with new winding cores. From DE 23 46 330 a reel cutting and winding machine for film strips is known, in which, following a longitudinal cutting station for cutting web strips from a web, a separation station is provided for separating adjacent web strips into separate winding axes, with alignment combs in the longitudinal grooves of each winding axis radial alignment edges are arranged adjustable, which position the winding tubes. From DE 23 65 606 a corresponding device is known in which, following a slitting station for cutting strips of film from a web, the films on individual Winding cores are guided and each winding core is assigned a drive roller resting on the circumference of the winding.

Die Erfindung betrifft eine Vorrichtung sowie ein Verfahren zum Schneiden und Aufwickeln von Folienstreifen, bestehend aus einer Querschneidestation für eine Folienbahn, einer anschließenden Längsschneideeinrichtung zum Trennen der Bahn in Folienstreifen sowie aus einer mit Wickelkernen bestückbaren Aufwickelvorrichtung für die Folienstreifen.The invention relates to a device and a method for cutting and winding up film strips, consisting of a cross-cutting station for a film web, a subsequent slitting device for separating the web into film strips, and a winding device for the film strips that can be equipped with winding cores.

Aus der EP-A 0 031 298 ist ein Verfahren beziehungsweise eine Vorrichtung zur Herstellung von Bandrollen von aus einem breiten Band geschnittenen schmalen Bandstreifen bekannt, wobei aus einem Materialband zunächst mindestens eine quer zur Bandbreite verlaufende Reihe Löcher eingestanzt wird. Dann wird ein mit druckklebendem Klebemittel versehener Klebestreifen unter Überdeckung der Löcher auf das Band aufgebracht und dieses so in Streifen geschnitten, daß jeder Streifen ein überdecktes Loch mindestens einer der Löcherreihen enthält. Beim Aufwickeln des Bandstreifens auf einen Rollenkern befindet sich ein überdecktes Stanzloch nahe dem beim Aufrollen vorauslaufenden und/oder nachlaufenden Bandstreifenende. Nun wird ein solcher Bandstreifen dem Rollenkern zugeführt und aufgewickelt, wobei auf die Außenseite des Klebstreifens Druck ausgeübt wird. Das vorauslaufende Bandstreifenende wird hierdurch auf dem Rollenkern angeklebt. Bei vollständig aufgewickelter Bandstreifenrolle wird durch den Druck auf den Klebstreifen über dem Loch am nachlaufenden treifenende dieses Ende auf die darunter liegende Wicklung der Bandstreifenrolle aufgeklebt. Diese Vorrichtung ist beim Schneiden in sehr schmale Streifen, beispielsweise 3,81 mm breite Streifen aus einer Magnetbandbahn kaum anwendbar, da das Ankleben eines Streifens am Rollenkern nicht zu bewerkstelligen ist.EP-A 0 031 298 discloses a method and an apparatus for producing tape rolls from narrow tape strips cut from a wide tape, at least one row of holes running across the tape being punched out from a material tape. An adhesive strip provided with pressure-sensitive adhesive is then applied to the tape, covering the holes, and the tape is cut into strips such that each strip contains a covered hole in at least one of the rows of holes. When the strip is wound onto a roll core, there is a covered punch hole near the end and / or the end of the strip that is leading and / or trailing. Now such a strip of tape is fed to the roll core and wound up, pressure being exerted on the outside of the adhesive strip. The leading end of the strip is glued to the roll core. When the tape roll is completely wound up, pressure is applied to the adhesive tape above the hole at the trailing end of the tape to glue this end to the winding of the tape roll underneath. This device can hardly be used when cutting into very narrow strips, for example 3.81 mm wide strips from a magnetic tape web, since it is not possible to glue a strip onto the roll core.

Ferner sind Wickelvorrichtungen für geschnittene Bahnstreifen bekannt, bei denen die Streifen über einen sogenannten Spreizkamm geführt werden, das sind Stifte, die die Folienstreifen in verschiedene Richtungen ablenken und wobei die Streifen mit einer Vorrichtung gemäß der oben genannten DE 23 65 606 aufgewickelt werden. Dies bedingt, wie schon oben ausgeführt, einen umfangreichen Aufwand beim Spulenwechsel, sobald der volle Wickelumfang erreicht ist. Wird beispielsweise eine 65 cm breite Magnetbandbahn in 3,81 mm breite Streifen längs geschnitten, welche auf Wickelkerne aufgewickelt werden, so müssen cirka 170 Bandwickel am Ende festgeklebt und von der Wickelachse abgenommen werden, wonach diese Wickelachsen neu mit Kernen bestückt werden, auf denen dann die Anfänge der Folienstreifen befestigt werden müssen. Dies kann eine erhebliche Umrüstzeit bedeuten, die etwa so lang ist wie die Aufwickelzeit. Ein weiterer Arbeitsgang entsteht dadurch, daß die fertigen Bandwickel zum Transport gegebenenfalls mit Zwischenlagefolien versehen und aufeinander gestapelt in größeren Gebinden verschickt werden müssen.Furthermore, winding devices for cut web strips are known, in which the strips are guided over a so-called spreading comb, which are pins which deflect the film strips in different directions and the strips are wound up with a device according to DE 23 65 606 mentioned above. As already explained above, this requires extensive effort when changing the bobbin as soon as the full winding circumference is reached. If, for example, a 65 cm wide magnetic tape web is cut lengthways into 3.81 mm wide strips, which are wound on winding cores, then about 170 tape windings have to be glued at the end and removed from the winding axis, after which these winding axes are newly equipped with cores, on which then the beginnings of the film strips must be attached. This can mean a considerable changeover time, which is approximately as long as the winding time. A further work step arises from the fact that the finished tape rolls may have to be provided with intermediate layers for transport and stacked on top of each other in larger containers.

Außerdem beansprucht die oben beschriebene Vorrichtung einen erheblichen räumlichen Umfang. Daher bestand die Aufgabe, eine Wickelvorrichtung der oben genannten gattungsmäßigen Art zu finden, welche

  • kompakt aufgebaut ist
  • erheblich reduzierte Umrüstzeiten beim Wickelwechsel mit sich bringt
  • bereits weitgehend versandfertige Wickelpakete liefert.
In addition, the device described above takes up a considerable amount of space. Therefore, the task was to find a winding device of the generic type mentioned above, which
  • is compact
  • significantly reduced changeover times when changing the wrap
  • already delivers ready-to-ship winding packages.

1. Aufbau der erfindungsgemäßen Vorrichtung1. Structure of the device according to the invention

Figur 1 zeigt schematisch die Seitenansicht einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung. Die von einer (nicht gezeichneten) Gieß- oder Extrusionseinrichtung kommende Folienbahn (1) wird in Pfeilrichtung über eine weiter unten noch zu beschreibenden Querschneideeinrichtung (2) sowie nachfolgend über einen Schleifenzieher (8) zum Ausgleich von Bahnspannungsschwankungen geführt. Nachfolgend wird die Bahn mittels einer Trennmesseranordnung (9), deren Achse senkrecht zur Folienbahnrichtung angeordnet ist oder eines Rollenschneiders in schmale Streifen (4) längs geschnitten. Derartige Anordnungen sind aus zahlreichen Veröffentlichungen bekannt, beispielsweise aus der DE 24 05 849 oder der DE 37 01 716 der Anmelderin, wo insbesondere Anordnungen zum Schneiden von Magnetbandbahnen in Folienstreifen beschrieben sind.Figure 1 shows schematically the side view of a preferred embodiment of the device according to the invention. The film web (1) coming from a casting or extrusion device (not shown) is fed in the direction of the arrow via a cross cutting device (2) to be described further below and subsequently via a loop puller (8) to compensate for web tension fluctuations guided. The web is subsequently cut lengthwise into narrow strips (4) by means of a separating knife arrangement (9), the axis of which is arranged perpendicular to the direction of the film web, or a reel cutter. Such arrangements are known from numerous publications, for example from DE 24 05 849 or DE 37 01 716 from the applicant, where in particular arrangements for cutting magnetic tape webs in film strips are described.

Die geschnittenen Streifen werden zwischen einer anschwenkbaren Andruckwalze (6), deren Breite mindestens so groß ist wie die gesamte Folienbahnbreite sowie einem Führungs-Saugkamm (3) hindurchgeführt. Der Saugkamm besteht (Figur 2) aus einer Anzahl senkrecht angeordneter Segmente (5), deren Zahl und Breite der Anzahl und Breite der Folienstreifen entspricht und die mit Unterdruck beaufschlagbar sind. Die Segmente sind jeweils voneinander im Abstand angeordnet. Der Saugkamm ist lateral in Folienlaufrichtung verschiebbeziehungsweise schwenkbar.The cut strips are passed between a pivotable pressure roller (6), the width of which is at least as large as the entire width of the film web, and a guide suction comb (3). The suction comb consists (FIG. 2) of a number of vertically arranged segments (5), the number and width of which corresponds to the number and width of the film strips and which can be subjected to negative pressure. The segments are spaced from each other. The suction comb is laterally pivotable in the film running direction.

Benachbart dem Saugkamm (3) befindet sich in Laufrichtung der Streifen ein vertikal zur Folienebene sowie quer zur Laufrichtung verschiebbares Schneidrad (7) oder ein querbewegtes Schneidmesser.Adjacent to the suction comb (3) in the direction of travel of the strips is a cutting wheel (7) which can be moved vertically to the film plane and transversely to the direction of travel, or a cutting knife which is moved transversely.

Die Aufwicklung der Folienstreifen (4) wird durch eine drehbare Aufwickelvorrichtung (10) bewerkstelligt, bestehend aus mindestens zwei Armen (12, 12′) , an deren freien Enden sich jeweils als Wickelachse eine antreibbare Welle (13, 13′) befindet. Auf die Wickelwellen sind beispielsweise Flanschspulen oder flanschlose Wickelkerne (14, 14′) aufspannbar. Bevorzugt zur Bewicklung gemäß der erfindungsgemäßen Vorrichtung sind flanschlose Wickelkerne und besonders bevorzugt stapelbare Wickelkerne gemäß DE 24 48 853, welche so aufeinander gestapelt auf eine Wickelwelle gespannt werden, daß die Wickel beziehungsweise die Wickelflächen praktisch abstandslos aneinander liegen. Zwischen den Wickelkernen können sich als Zwischenlagen dünne kreisförmige Folien (21), bestehend aus Kunststoff, Pappe oder Papier befinden, deren Durchmesser gleich oder vorzugsweise größer ist als der maximale Durchmesser der Bandwickel.The winding of the film strips (4) is accomplished by a rotatable winding device (10) consisting of at least two arms (12, 12 '), at the free ends of which a drivable shaft (13, 13') is located as the winding axis. On the winding shafts For example, flange coils or flangeless winding cores (14, 14 ') can be clamped. Flange-less winding cores and particularly preferably stackable winding cores according to DE 24 48 853 are preferred for the winding according to the device according to the invention, which are stacked on top of one another so that they are tensioned on a winding shaft in such a way that the windings or the winding surfaces are practically spaced apart. Between the winding cores there can be thin circular foils (21) consisting of plastic, cardboard or paper, the diameter of which is equal to or preferably greater than the maximum diameter of the tape winding.

Die bereits genannte Querschneideeinrichtung (2) dient zur Herstellung einer definierten Bandlänge, wobei eine Bandlänge mit der nachfolgenden mit einer bestimmten Klebestelle versehen wird. Gemäß Figur 3 besteht diese Einrichtung in einer bevorzugten Ausführung aus einem dreiteiligen Schneidtisch. Dieser besitzt zwei feste parallel angeordnete Auflageschienen (16, 17) quer zur Folienlaufrichtung sowie eine dazwischen angeordnete vertikal verschiebbare schmale Auflageschiene (18). Zwischen den beiden Spalten der Schienen (16, 17) und der vertikal verschiebbaren Schiene (18) können zwei Schneidrädchen (15, 15′) oder Schneidmesserklingen zum Querschneiden der Bahn (1) eintauchen. Als Klebeband (22) zum Verbinden der beiden getrennten Bahnstücke wird vorzugsweise ein mit einer Klebefläche versehenes Band verwendet, dessen beide seitliche Enden (19, 19′) von der Klebefläche (20) abgewandt unter stumpfem Winkel abgeknickt und klebstoffrei sind (Figur 4).The cross-cutting device (2) already mentioned is used to produce a defined strip length, one strip length being provided with the following one with a specific adhesive point. According to Figure 3, this device consists in a preferred embodiment of a three-part cutting table. This has two fixed support rails (16, 17) arranged parallel to one another transversely to the film running direction and a narrow support rail (18) arranged vertically displaceable between them. Between the two columns of the rails (16, 17) and the vertically displaceable rail (18), two cutting wheels (15, 15 ') or cutting knife blades for cross-cutting the web (1) can be immersed. As an adhesive tape (22) for connecting the two separate web pieces, a tape provided with an adhesive surface is preferably used, the two lateral ends (19, 19 ') of which are turned away from the adhesive surface (20), are bent at an obtuse angle and are adhesive-free (FIG. 4).

In einer anderen Ausführung kann der Schneidetisch aus lediglich zwei Auflageschienen bestehen, mit einem dazwischen befindlichen Spalt, wobei eine Schiene nach dem Trennen der Bahn horizontel um die Breite der Schiene (18) verschoben wird und wobei nachfolgend die Klebeverbindung hergestellt wird.In another embodiment, the cutting table can consist of only two support rails, with one in between located gap, wherein a rail is horizontally displaced after the separation of the web by the width of the rail (18) and wherein the adhesive connection is subsequently made.

Ebenso kann das Klebeband (22) auch nur ein klebstofffreies abgeknicktes Ende besitzen.Likewise, the adhesive tape (22) can also have only one glue-free, bent end.

2. Wirkungsweise der erfindungsgemäßen Vorrichtung zum Spulenwechsel2. Mode of operation of the device for changing bobbins according to the invention

Auf der gerade zum Stillstand gekommenen Wickelwelle (13) befinden sich die auf den Wickelkernen (14) aufgewickelten vollen Bandwickel (23) mit je einem Klebeband (22) auf dem äußeren Umfang des Bandwickels. Daraufhin wird die Walze (6) an den Saugkamm (3) angeschwenkt, dessen Segmente (5) mit Unterdruck beaufschlagt werden, so daß sie die Folienstreifen (4) ansaugen. Die drehbare Walze (6) ist auf ihrer zylindrischen Fläche (24) mit einer Flüssigkeit benetzt beispielsweise Wasser zum Anfeuchten der Unterseite der Folienbahnstreifen. Nun wird das Schneidrad (7) auf die Folienebene abgesenkt und quer zur Bahnrichtung werden die Folienstreifen (4) abgetrennt. Dabei bleibt von der Klebestelle (22) bis zum Folienende ein Folienrest (4′) von 5 bis 20 cm übrig, von der Schnittstelle bis zum Beginn des Saugkamms (3) etwa 5 bis 10 cm.On the winding shaft (13), which has just come to a standstill, the full tape windings (23) wound on the winding cores (14) are each with an adhesive tape (22) on the outer circumference of the tape winding. The roller (6) is then pivoted onto the suction comb (3), the segments (5) of which are subjected to negative pressure, so that they suck in the film strips (4). The rotatable roller (6) is wetted on its cylindrical surface (24) with a liquid, for example water, for moistening the underside of the film web strips. Now the cutting wheel (7) is lowered onto the film level and the film strips (4) are cut off transversely to the web direction. This leaves from the glue point (22) to the end of the film a film residue (4 ') of 5 to 20 cm, from the interface to the beginning of the suction comb (3) about 5 to 10 cm.

Sind die Folienstreifen abgetrennt, so dreht sich die Wickelvorrichtung (10) um 180°, so daß sich jetzt die auf der Wickelwelle (13′) bereits aufgesteckten unbewickelten Kerne (14′) benachbart zum Saugkamm befinden. Die Walze (6) wird vom Saugkamm weggeschwenkt, worauf dieser mit den festgehaltenen Streifenenden (4) an die Wickelwelle (13′) mit den Kernen (14′) bis auf einen geringen Abstand angeschwenkt wird, so daß er in die in Figur 1 gestrichelt gezeichnete Stellung gelangt. Auf den Wickelkernen (14′) kommen jetzt die angefeuchteten Unterseiten der Enden der geschnittenen Streifen (4) zu liegen. Ebenso können auch die Leerkerne (14′) vorher durch eine entsprechende Einrichtung befeuchtet worden sein. Zur Erleichterung des eben beschriebenen Einfädelns kann die äußere Peripherie der zwischen den Wickelkernen vorgesehenen Zwischenlagefolien (21) in die offenen Spalten (25) zwischen den Segmenten (5) des Führungs-Saugkamms (3) eintauchen. Dies kann erleichtert werden, indem die Wickelwelle (13′) zum Beispiel kurz anläuft und damit die Zwischenlagen infolge Zentrifugalkraft gestrafft werden.Are the film strips separated, the winding device (10) rotates through 180 °, so that the unwound cores (14 ') already plugged onto the winding shaft (13') are located adjacent to the suction comb. The roller (6) is pivoted away from the suction comb, whereupon the latter with the held strip ends (4) the winding shaft (13 ') with the cores (14') is pivoted to a short distance, so that it reaches the position shown in dashed lines in Figure 1. On the winding cores (14 ') now come the moistened undersides of the ends of the cut strips (4) to lie. Likewise, the empty cores (14 ') may have been moistened beforehand by an appropriate device. To facilitate the threading just described, the outer periphery of the intermediate layer foils (21) provided between the winding cores can be immersed in the open gaps (25) between the segments (5) of the guide suction comb (3). This can be facilitated by the winding shaft (13 ') starting up briefly, for example, and the intermediate layers being tightened as a result of centrifugal force.

Jetzt wird die Wickelwelle (13′) erst langsam dann schneller angetrieben und der Wickelvorgang beginnt, während gleichzeitig der Unterdruck von den Segmenten (5) weggenommen wird. Der Saugkamm wird entweder plötzlich oder allmählich zunehmend mit dem Wickeldurchmesser (23′) des neu entstehenden Bandwickels weggeschwenkt und gelangt wieder an seine ursprüngliche Position (Figur 1). Während dieses Wickelvorgangs, der mit hoher Geschwindigkeit, etwa bis 1000 m/min. erfolgen kann, können auf dem Arm (12) der Vorrichtung (10) alle fertigen Bandwickel (23) komplett als Einheit abgenommen und versandfertig verpackt werden, beispielsweise in einer Verpackungseinheit gemäß der DE-PS 26 55 254 oder gemäß den DE-GM 87 16 579 und 87 16 580 oder 88 03 062 der Anmelderin. Daraufhin wird die Welle (13) mit leeren Wickelkernen neu bestückt.Now the winding shaft (13 ') is only slowly driven then faster and the winding process begins, while at the same time the negative pressure is removed from the segments (5). The suction comb is either suddenly or gradually swiveled away with the winding diameter (23 ') of the newly emerging tape roll and returns to its original position (Figure 1). During this winding process, the high speed, up to about 1000 m / min. can take place, on the arm (12) of the device (10) all finished tapes (23) can be completely removed as a unit and packed ready for dispatch, for example in a packaging unit according to DE-PS 26 55 254 or DE-GM 87 16 579 and 87 16 580 or 88 03 062 from the applicant. The shaft (13) is then re-equipped with empty winding cores.

Zweckmäßigerweise wird eine definierte Bandlänge der Folienbahn durch die bereits beschriebene Querschneideeinrichtung (2) hergestellt. Dies geschieht, indem in bestimmten Abständen die Folienbahn auf dieser Einrichtung mit den Schneidrädchen (15, 15′) bei stillstehender Bahn quergeschnitten wird, anschließend wird die Auflageschiene nach unten verschoben und das auf ihr befindliche schmale Bandstück auf irgend eine Weise entfernt. Dann wird ein Klebeband (22) aufgelegt und die beiden Bandenden werden durch die Klebefläche (20) miteinander verbunden. Zwischen den Bandenden befindet sich ein kurzer Abstand, der einige Millimeter bis einige Zentimeter betragen kann. Erreicht diese Klebestelle den Bandwickel auf der Wickelwelle (13 oder 13′), haftet das Bandende und der Wickelvorgang wird beendet. Er kann dann wie oben beschrieben in einem neuen Zyklus fortgesetzt werden.A defined strip length of the film web is expediently achieved by the cross-cutting device already described (2) manufactured. This is done by cutting the film web at certain intervals on this device with the cutting wheels (15, 15 ') while the web is stationary, then the support rail is moved down and the narrow piece of tape located on it is removed in some way. Then an adhesive tape (22) is put on and the two tape ends are connected to each other by the adhesive surface (20). There is a short distance between the tape ends, which can be a few millimeters to a few centimeters. If this glue point reaches the tape winding on the winding shaft (13 or 13 '), the tape end is liable and the winding process is ended. It can then be continued in a new cycle as described above.

Aus dem vorstehend Beschriebenen ist zu ersehen, daß mit der erfindungsgemäßen Vorrichtung die Umrüstzeiten beim Wickelwechsel wesentlich verkürzt werden und daß gleichzeitig jeweils ein komplettes versandfertiges Gebinde abgenommen werden kann. Auf diese Weise ist es möglich, beispielsweise bei der Herstellung von magnetischen Aufzeichnungsträgern durch Beguß einer magnetischen Dispersion auf einen unmagnetischen Schichtträger, online nach dem Trocknen und Kalandrieren der begossenen Folienbahn diese in Längsstreifen zu trennen und aufzuwickeln, zumal der kompakte Aufbau der erfindungsgemäßen Vorrichtung diesem Arbeitsgang entgegenkommt.It can be seen from what has been described above that the changeover times for changing the wrap are substantially shortened with the device according to the invention and that a complete package ready for dispatch can be removed at the same time. In this way it is possible, for example in the production of magnetic recording media by pouring a magnetic dispersion onto a non-magnetic substrate, online after drying and calendering the cast film web into longitudinal strips and winding them up, especially since the compact structure of the device according to the invention this operation accommodates.

Der Weiterverarbeiter kann dann beispielsweise zum Zweck des Loadens oder Windens von Magnetband und Cassetten leicht die Klebestellen bei jedem Magnetbandwickel, dem sogenannten Pancake an dem abstehenden Ende der Klebestelle öffnen, die kurzen Folienreste (4′) entfernen und dann die Magnetbandstreifen in Loader oder Winder gemäß dem bekannten Stand der Technik einführen.The processor can then, for example, for the purpose of loading or winding magnetic tape and cassettes, easily open the glue points on each magnetic tape roll, the so-called pancake at the protruding end of the glue point, remove the short film residues (4 ') and then according to the magnetic tape strips in loader or winder introduce the known prior art.
