Definitions
- the present invention relates to a flexible tape provided with a Velcro zipper according to the preamble of claim 1 and to a use of the flexible tape as a winding tape according to claim 10.
- a Velcro zipper has two flat closure parts, each of which has a pile, and which, when brought into contact with one another with slight pressure, adhere to one another.
- the locking parts brought into mutual engagement are able to withstand very considerable forces insofar as these run approximately parallel to their surface.
- the two closure parts can then be separated from one another again by lifting them off.
- Velcro zippers There are two types of Velcro zippers. In one type, for example in the one known under the brand name "Velcro", one closure part has a pile which consists exclusively of hooks and the other closure part has a pile which consists exclusively of loops. In the other type of Velcro zippers, both fastener parts have a pile that has both hooks and loops.
- the pile of the fastener parts is a relatively delicate element.
- the hooks which consist of a monofilament, can permanently deform under repeated pressure, for example against a hard surface.
- the loops of the loop pile can also be flattened over time on the base fabric in question will. In both cases, such "aging" phenomena mean that the two closure parts gradually become less grippy and do not adhere sufficiently to one another over time.
- a Velcro fastener the fastener parts of which are in engagement with one another, is exposed to pressure for a prolonged period. This also applies to the band of the generic type known from US Pat. No. 3,543,977 and provided with a Velcro zipper.
- the proposed flexible tape has the features specified in the characterizing part of claim 1.
- a belt which has a toothed belt piece as a locking mechanism at each of its ends.
- the teeth of the two toothed belt pieces engage with one another and prevent the belt ends from shifting in the longitudinal direction of the belt.
- Velcro fastener parts are arranged on the side of the toothed belt pieces, the pile parts of which have a significantly lower height than the associated toothed belt pieces. The Velcro fastener parts are used to hold the strap ends in place and therefore have not the task of taking tensile forces in the longitudinal direction of the belt.
- the toothed belt pieces which are not spacers in the sense of the subject matter of the invention, serve this purpose.
- the embodiment shown in US-A-3,464,094 is not a tape, but a liquid-tight seal between two parts. Between the pile parts, which are attached to these two parts, elongated strips of soft compressible material are arranged, which are higher than the pile. When the closure is closed, these two compressible strips are pressed together, thereby achieving the desired tightness. This compression maintains the flexibility and compressibility of the sealing strips. The pile is not protected under pressure.
- the Velcro zipper shown in FIGS. 1-5 is attached to a flexible band 11, for example by sewing or gluing. It has two closure parts 11 (Fig. 2) and 12 (Fig. 3). Both closure parts have a base fabric 13 which is provided with a pile. In the case of the closure part 11, this is a hook pile 14 in this example and a loop pile 15 in the closure part 12. However, the pile of both closure parts does not cover the entire width of the base fabric 13 but is divided into two pile sections 14a, 14b and 15a, 15b, respectively, which the two Cover edge areas of the base fabric 13. Between the pile sections 14a, 14b and 15a, 15b, a band-shaped spacer 16 is fastened to the base fabric 13, for example by gluing.
- the spacer 16 is made of a pressure-resistant material and consists for example of a solid and flexible plastic band.
- the spacer 16 has a thickness which at most corresponds to the height of the associated pile 14, 15 and which in the present exemplary embodiment is slightly smaller than the associated pile 14 or 15. In the present case it is the spacer is smaller by the amount than the associated pile 14 or 15, which is sufficient to bring the pile of the two closure parts into sufficient engagement with one another (cf. also FIG. 12).
- the closure part 11 is fastened to one side, leaving a rounded band tongue 17 (FIG. 4) near the end of the band 10.
- the closure part 12 is fastened at a distance from the closure part 11 on the other side of the band 10.
- the closure part 11 is also considerably shorter than the closure part 12. The reason for this arrangement (which is not shown to scale in FIG.
- the spacer 16 in the closure part 11 is longer than the pile sections 14a, 14b and protrudes beyond these pile sections on both ends.
- the end regions 16 'of the spacer 16 both in FIG. 4 and in FIG. 5 are chamfered, that is to say of a continuously decreasing thickness, so that they do not end in one step.
- the strip 10 shown can thus be wound up with the closure parts 11 and 12, for example, on a supply reel without substantial discontinuities.
- FIG. 6 If one observes FIG. 6, one can see a winding 20, indicated only schematically, of flat structures wound on a winding core 21 with the aid of the band 10 as a winding band in a scale formation (not shown in FIG. 6, designated 22 in FIG. 13).
- the winding tape 10 was pulled off a supply roll 23 during the winding-up process and passed between a pair of rolls 24 braked here to the roll 20.
- the path of the winding tape 10 is indicated by the dash-dotted line 25.
- the sheet 20 is no longer supplied with flat structures and the winding tape 10 has already wrapped around the roll 20 at least once more.
- the closure part 12 is fastened to the winding tape 10 on the side facing away from the winding 20 and has a length which exceeds that of the winding circumference.
- the closure part 11 is fastened on the side of the winding tape 10 facing the winding 20, so that only the end of the winding tape 10 visible in FIG. 6 is to be placed on the previously wound additional turn and pressed lightly, and the entire winding 20 is fixed .
- the side view of the winding 20 fixed with the winding tape 10 according to FIG. 10 shows that the tape tongue 17 at the end of the winding tape 10 remote from the winding core is stiffened by the extension 16 'of the spacer 16 via the closure part 11 (FIG. 2) and therefore protrudes from the winding circumference.
- the band tongue 17 thus forms a convenient handle for separating the closure parts 11 and 12 from one another.
- FIG. 11 shows that the length of the pile sections 15a and 15b of the closure part 12 (FIG. 5) far exceeds that of the closure part 11, which is not visible here. Part of the pile sections 15a and 15b is therefore freely accessible from the outside. But even if the wrap 20 is supported or unrolled on its circumference on the ground would, these pile sections 15a, 15b take no damage, because the spacer 16 arranged between them largely keeps the compressive stress emanating from the weight of the roll 20 away from the pile sections 15a, 15b.
- FIG. 13 shows a further advantageous property of the winding tape described here, for example, or the spacers present between the pile sections 15a, 15b and the pile sections 14a and 14b.
- the spacers 16, which - in the present example - as mentioned - consist of a solid but flexible plastic band and at their ends 16 '(see FIGS. 4 and 5) have a continuously decreasing thickness, form an ideal slip for a flat, spatula-like tool 28, with which the process of releasing the Velcro zipper can be initiated without damaging the pile sections.
- closure part 12 provided with the loop pile sections 15a and 15b is longer than the closure part 11 provided with the hook pile sections 14a, 14b, it is of course also possible to make both closure parts 11, 12 of the same length, or the closure part 11 with loop pile and to provide the closure part 12 with hook pile.
- the arrangement of the spacer (s) 16 is also adapted to the intended use in the example described.
- two spacer strips could also be attached to the edge regions of the band 10 and the space between these spacer strips could be occupied by a single pile section.

Abstract
Description
Die vorliegende Erfindung betrifft ein mit einem Klettenreissverschluss versehenes biegsames Band gemäss Oberbegriff des Anspruches 1 sowie eine Verwendung des biegsamen Bandes als Wickelband gemäss Anspruch 10.The present invention relates to a flexible tape provided with a Velcro zipper according to the preamble of claim 1 and to a use of the flexible tape as a winding tape according to
Bekanntlich hat ein Klettenreissverschluss zwei flächige Verschlussteile, die je einen Flor aufweisen, und die - wenn gegenseitig mit geringem Druck in Berührung gebracht - aneinander haften. Die in gegenseitigen Eingriff gebrachten Verschlussteile vermögen ganz erheblichen Kräften zu widerstehen, soweit diese etwa parallel zu ihrer Fläche verlaufen. Beide Verschlussteile können sodann durch abhebendes Abreissen wieder voneinander getrennt werden.As is known, a Velcro zipper has two flat closure parts, each of which has a pile, and which, when brought into contact with one another with slight pressure, adhere to one another. The locking parts brought into mutual engagement are able to withstand very considerable forces insofar as these run approximately parallel to their surface. The two closure parts can then be separated from one another again by lifting them off.
Dabei gibt es zweierlei Klettenreissverschlüsse. Bei der einen Art, beispielsweise bei jener, die unter dem Markennamen "Velcro" bekannt ist, besitzt das eine Verschlussteil einen Flor, der ausschliesslich aus Haken besteht und das andere Verschlussteil einen Flor, der ausschliesslich aus Schlingen besteht. Bei der anderen Art klettenreissverschlüsse besitzen beide Verschlussteile einen Flor, der sowohl Haken als auch Schlingen aufweist.There are two types of Velcro zippers. In one type, for example in the one known under the brand name "Velcro", one closure part has a pile which consists exclusively of hooks and the other closure part has a pile which consists exclusively of loops. In the other type of Velcro zippers, both fastener parts have a pile that has both hooks and loops.
Bei den bekannten Klettenreissverschlüssen ist der Flor der Verschlussteile ein relativ heikles Element. Namentlich die aus einem Monofilament bestehenden Haken können bei wiederholter und starker Druckbeanspruchung, beispielsweise gegen eine harte Unterlage, sich bleibend deformieren. Auch die Schlingen des Schlingenflors können mit der Zeit auf das betreffende Grundgewebe flachgedrückt werden. In beiden Fällen führen solche "Alterungs"-Erscheinungen dazu, dass die beiden Verschlussteile allmählich nicht mehr so griffig und mit der Zeit nicht mehr ausreichend aneinander haften. Dasselbe trifft zu, wenn ein Klettenverschluss, dessen Verschlussteile miteinander im Eingriff stehen, über längere Zeit einer Ueberbeanspruchung auf Druck ausgesetzt ist. Dies trifft auch auf das aus der US-A-3,543,977 bekannte, mit einem Klettenreissverschluss versehene Band der gattungsgemässen Art zu.In the known Velcro zippers, the pile of the fastener parts is a relatively delicate element. In particular, the hooks, which consist of a monofilament, can permanently deform under repeated pressure, for example against a hard surface. The loops of the loop pile can also be flattened over time on the base fabric in question will. In both cases, such "aging" phenomena mean that the two closure parts gradually become less grippy and do not adhere sufficiently to one another over time. The same applies if a Velcro fastener, the fastener parts of which are in engagement with one another, is exposed to pressure for a prolonged period. This also applies to the band of the generic type known from US Pat. No. 3,543,977 and provided with a Velcro zipper.
Es ist daher eine Aufgabe der Erfindung, ein mit einem Klettenreissverschluss versehenes biegsames Band der eingangs genannten Art derart zu verbessern, dass der Flor beider Verschlussteile, ob in gelöstem Zustand oder in gegenseitigem Eingriff, gegen eine Ueberbeanspruchung auf Druck weitgehend geschützt bleibt, so dass der Flor keinen Schaden erleidet.It is therefore an object of the invention to improve a flexible tape provided with a Velcro zipper of the type mentioned in such a way that the pile of both fastener parts, whether in the released state or in mutual engagement, remains largely protected against excessive pressure, so that the Flor suffered no harm.
Zur Lösung dieser Aufgabe weist das vorgeschlagene biegsame Band die im Kennzeichen des Anspruches 1 angegebenen Merkmale auf.To solve this problem, the proposed flexible tape has the features specified in the characterizing part of claim 1.
Aus der CH-A-360 592 ist nun ein Gurt bekannt, der als Verschliessmechanismus an jedem seiner Enden ein Zahnriemenstück aufweist. Im geschlossenen Zustand greifen die Zähne der beiden Zahnriemenstücke eineinander ein und verhindern ein Verschieben der Gurtenden in Gurtlängsrichtung. Seitlich der Zahnriemenstücke sind Klettenverschlussteile angeordnet, deren Florteile eine deutlich geringere Höhe haben als die zugeordneten Zahnriemenstücke. Die Klettenverschlussteile dienen dazu, die Gurtenden in ihrer Position zu halten und haben also nicht die Aufgabe, Zugkräfte in Längsrichtung des Gurtes zu übernehmen. Dazu dienen wie bereits dargelegt die Zahnriemenstücke, welche keine Abstandhalter im Sinne des Erfindungsgegenstandes sind.From CH-A-360 592 a belt is now known which has a toothed belt piece as a locking mechanism at each of its ends. When closed, the teeth of the two toothed belt pieces engage with one another and prevent the belt ends from shifting in the longitudinal direction of the belt. Velcro fastener parts are arranged on the side of the toothed belt pieces, the pile parts of which have a significantly lower height than the associated toothed belt pieces. The Velcro fastener parts are used to hold the strap ends in place and therefore have not the task of taking tensile forces in the longitudinal direction of the belt. As already explained, the toothed belt pieces, which are not spacers in the sense of the subject matter of the invention, serve this purpose.
Bei der in der US-A-3,464,094 gezeigten Ausführungsform handelt es sich nicht um ein Band, sondern um einen flüssigkeitsdichten Verschluss zwischen zwei Teilen. Zwischen Florteilen, die an diesen beiden Teilen angebracht sind, sind längliche Streifen aus weichem kompressiblem Material angeordnet, die höher sind als der Flor. Beim Schliessen des Verschlusses werden diese beiden kompressiblen Streifen zusammengedrückt, wodurch die gewünschte Dichtheit erzielt wird. Bei diesem Zusammendrücken wird die Flexibilität und die Kompressibilität der Dichtstreifen erhalten. Ein Schutz des Flores bei Druckbelastung erfolgt demnach nicht.The embodiment shown in US-A-3,464,094 is not a tape, but a liquid-tight seal between two parts. Between the pile parts, which are attached to these two parts, elongated strips of soft compressible material are arranged, which are higher than the pile. When the closure is closed, these two compressible strips are pressed together, thereby achieving the desired tightness. This compression maintains the flexibility and compressibility of the sealing strips. The pile is not protected under pressure.

Der in den Fig. 1-5 gezeigte Klettenreissverschluss ist auf einem biegsamen Band 11 befestigt, beispielsweise durch Vernähung oder Verklebung. Er besitzt zwei Verschlussteile 11 (Fig. 2) und 12 (Fig. 3). Beide Veschlussteile weisen ein Grundgewebe 13 auf, das mit einem Flor versehen ist. Beim Verschlussteil 11 ist dies in diesem Beispiel ein Hakenflor 14 und beim Verschlussteil 12 ein Schlingenflor 15. Allerdings bedeckt der Flor beider Verschlussteile nicht die ganze Breite des Grundgewebes 13 sondern ist in zwei Florabschnitte 14a, 14b bzw. 15a, 15b aufgeteilt, die die zwei Randbereiche des Grundgewebes 13 belegen. Zwischen den Florabschnitten 14a, 14b bzw. 15a, 15b ist ein bandförmiger Abstandhalter 16 auf dem Grundgewebe 13 befestigt, beispielsweise durch Verklebung. Der Abstandhalter 16 ist aus einem druckfesten Material und besteht beispielsweise aus einem massiven und biegsamen Kunststoffband.The Velcro zipper shown in FIGS. 1-5 is attached to a
Wie den Fig. 2 und 3 zu entnehmen ist, besitzt der Abstandhalter 16 eine Dicke, die höchstens der Höhe des zugeordneten Flors 14, 15 entspricht und die im vorliegenden Ausführungsbeispiel geringfügig kleiner ist als der zugeordnete Flor 14 bzw. 15. Im vorliegenden Fall ist der Abstandhalter um dasjenige Mass geringer als der zugeordnete Flor 14 bzw. 15, das ausreicht, um den Flor der beiden Verschlussteile in ausreichenden Eingriff miteinander zu bringen (vgl. auch Fig. 12). In Fig. 1 ist das Verschlussteil 11 unter Freilassung einer verundeten Bandzunge 17 (Fig. 4) in der Nähe des Endes des Bandes 10 auf dessen einer Seite befestigt. Dagegen ist das Verschlussteil 12 in einem Abstand vom Verschlussteil 11 auf der anderen Seite des Bandes 10 befestigt. Das Verschlussteil 11 ist auch erheblich kürzer als das Verschlussteil 12. Der Grund für diese (in Fig. 1 nicht massstäblich wiedergegebene) Anordnung ist, wie sich noch zeigen wird, in der bevorzugten Verwendung des Bandes 10 zu sehen. Ausserdem ist zu beachten, dass beim Verschlussteil 11 der Abstandhalter 16 länger ist als die Florabschnitte 14a, 14b und beiderends über diese Florabschnitte vorsteht. Die Endbereiche 16' des Abstandhalters 16 sowohl in Fig. 4 als auch in Fig. 5 sind abgeschrägt, das heisst von stetig abnehmender Dicke, so dass sie nicht in einer Stufe enden. Damit kann das dargestellte Band 10 mit den Verschlussteilen 11 und 12 ohne wesentliche Unstetigkeiten beispielsweise auf eine Vorratsspule aufgewickelt werden.As can be seen from FIGS. 2 and 3, the
Beachtet man die Fig. 6, so erkennt man einen nur schematisch angedeuten Wickel 20 von auf einem Wickelkern 21 mit Hilfe des Bandes 10 als Wickelband in Schuppenformation aufgewickelten Flächengebilden (in Fig. 6 nicht dargestellt, in Fig. 13 mit 22 bezeichnet). Das Wickelband 10 wurde während des Aufwickelvorganges von einer Vorratsrolle 23 abgezogen und zwischen einem hier gebremsten Paar Rollen 24 hindurch zum Wickel 20 geführt. Der Weg des Wickelbandes 10 ist mit der strichpunktierten Linie 25 angedeutet. Im dargestellten Zustand werden dem Wickel 20 keine Flächengebilde mehr zugeführt und das Wickelband 10 hat bereits den Wickel 20 mindestens einmal zusätzlich umschlungen. Der Verschlussteil 12 ist auf der dem Wickel 20 abgekehrten Seite auf dem Wickelband 10 befestigt und hat eine Länge, die jene des Wickelumfanges übersteigt. Das Verschlussteil 11 dagegen ist auf der dem Wickel 20 zugekehrten Seite des Wicklebandes 10 befestigt, so dass nur noch das in Fig. 6 sichtbare Ende des Wicklebandes 10 auf die zuvor schon aufgewickelte zusätzliche Windung aufzulegen und leicht anzudrücken ist und der gesamte Wickel 20 ist fixiert.If one observes FIG. 6, one can see a winding 20, indicated only schematically, of flat structures wound on a winding
Analoges geschieht beim Abwickeln des Wickels 20 (Fig. 7), bei dem das Wickelband wiederum zwischen den Rollen 24 hindurch vom Wickel 20 abgezogen und auf die nun angetriebene Vorratsrolle 23 aufgespult wird. Auch hier wird das seinerzeit am Wickelkern 21 befestigte Ende des Wickelbandes auf sich selbst auf der nun vollen Vorratsrolle 23 fixiert.The same happens when the
Im Schnitt der Fig . 8 erkennt man, dass der Kern 26 der Vorratsrolle 23 in den an ihre Seitenflansche 27 angrenzenden Bereichen etwas abgesetzt ist, um den Florabschnitt, der beim Aufwickeln auf die Vorratsrolle 23 direkt auf den Kern 26 zu liegen kommt, vom Druck der folgenden Windungen voll zu entlasten. Bei den auf die erste Windung folgenden Windungen sind es die unmittelbar aufeinander zu liegen kommenden Abstandhalter 16, die die daneben liegenden Florabschnitte vom Druck der übrigen Windungen des Wickelbandes weitgehend entlasten.In the section of Fig. 8 it can be seen that the
Aus Fig. 9 ist ersichtlich, dass wenn das Wickelband 10, mit einem der Verschlussteile 11 oder 12 zwischen den Rollen 24 hindurchläuft, diese Verschlussteile von der Druckwirkung im Rollenspalt weitgehend entlastet sind, weil diese Druckwirkung vom Abstandhalter 16 aufgenommen wird.It can be seen from FIG. 9 that when the winding
Die Seitenansicht des mit der Wickelband 10 fixierten Wikkels 20 gemäss Fig. 10 zeigt, dass die Bandzunge 17 an dem dem Wickelkern entfernten Ende des Wickelbandes 10 durch die Verlängerung 16′ des Abstandhalters 16 über das Verschlussteil 11 (Fig. 2) hinaus versteift ist und daher vom Wickelumfang absteht. Damit bildet die Bandzunge 17 eine bequeme Handhabe zum Trennen der Verschlussteile 11 und 12 voneinander.The side view of the winding 20 fixed with the winding
Die Frontansicht der Fig. 11 zeigt, dass die Länge der Florabschnitte 15a und 15b des Verschlussteiles 12 (Fig. 5) jene des hier nicht sichtbaren Verschlussteiles 11 bei weitem übertrifft. Ein Teil der Florabschnitte 15a und 15b ist also von aussen frei zugänglich. Aber selbst wenn der Wickel 20 auf seinem Umfang am Boden abgestützt oder abgerollt würde, nähmen diese Florabschnitte 15a, 15b keinen Schaden, weil der dazwischen angeordnete Abstandhalter 16 die vom Eigengewicht des Wickels 20 ausgehende Druckbeanspruchung weitgehend von den Florabschnitten 15a, 15b fernhält.The front view of FIG. 11 shows that the length of the
Schliesslich geht aus Fig. 13 eine weitere, vorteilhafte Eigenschaft des hier beispielsweise beschriebenen Wickelbandes bzw. der zwischen den Florabschnitten 15a, 15b und den Florabschnitte 14a und 14b vorhandenen Abstandhalter hervor.Finally, FIG. 13 shows a further advantageous property of the winding tape described here, for example, or the spacers present between the
Die Abstandhalter 16, die in vorliegendem Beispiel - wie erwähnt - aus einem massiven, jedoch biegsamen Kunststoffband und an ihren Enden 16′ (vgl. Fig. 4 und 5) eine stetig abnehmende Dicke aufweisen, bilden einen idealen Einschlupf für ein flaches, spatelartiges Werkzeug 28, mit dem der Vorgang des Lösens des Klettenreissverschlusses ohne Beschädigung der Florabschnitte eingeleitet werden kann.The
Während im beschriebenen Beispiel das mit den Schlingenflorabschnitte 15a und 15b versehene Verschlussteil 12 länger ist als das mit den Hakenflorabschnitten 14a, 14b versehene Verschlussteil 11, ist es selbstverständlich auch möglich, beide Verschlussteile 11, 12 gleich lang zu machen, oder das Verschlussteil 11 mit Schlingenflor und das Verschlussteil 12 mit Hakenflor zu versehen.While in the example described the
Auch die Anordnung des bzw. der Abstandhalter 16 ist im beschriebenen Beispiel dem Verwendungszweck angepasst.The arrangement of the spacer (s) 16 is also adapted to the intended use in the example described.
Für denselben Verwendungszweck könnten auch an den Randbereichen des Bandes 10 zwei Abstandhalterstreifen befestigt werden und der Zwischenraum zwischen diesen Abstandhalterstreifen könnte von einem einzigen Florabschnitt eingenommen werden.For the same purpose, two spacer strips could also be attached to the edge regions of the

- Tape according to Claim 1, characterised in that the end regions (16') of the spacers (16) of both fastener parts (11, 12) have a steadily decreasing thickness.
- Tape according to Claim 1 for holding together a coil (20) which consists of flat materials (22) wound together with the tape (10) onto a hub (21) of a coil, characterised in that the two fastener parts (11, 12) are arranged at the same end of the tape (10) and the second fastener part (12) is substantially longer than the first fastener part (11).
- Tape according to Claim 7, characterised in that the second fastener part (12) has a length which is greater than the circumference of the coil (20).
- Tape according to Claim 7, characterised in that fastener parts (11, 12) of a touch-and-close fastener are likewise arranged at the other end of the tape (10).
- Use of the tape according to one of Patent Claims 1-9 as a coiled tape (10) which comes to lie or lies between the coil layers of coils (20) of flat materials to be wound onto a hub (21) of a coil or unwound therefrom, characterised in that the coiled tape (10) is removably attached to the hub (21) of the coil by means of the touch-and-close fastener.
- Use according to Patent Claim 10, characterised in that one of the fastener parts (11, 12) is attached to or in the hub (21) of the coil and the other one of the fastener parts (12, 11) is attached to the side of the coiled tape (10) facing the hub of the coil in its end region near to the hub.
- Use according to Patent Claim 10, characterised in that the end region of the coiled tape (10) near to the hub is wrapped several times around the hub (21) of the coil and is attached to itself by means of the touch-and-close fastener.
- Use according to Patent Claim 10 or 11, characterised in that the end region of the coiled tape (10) remote from the hub bears the one fastener part (11) on the side facing the coil (20) and, with spacing therefrom, bears the other fastener part (12) on the side facing away from the coil (20), so that the coiled tape (10) can be fixed to itself in a removable manner after at least one additional wrapping of the coil (20).
- Use according to Patent Claim 10, characterised in that, in the interior of the hub (21) of the coil, a spool is provided, which is on the same or a parallel axis thereto, for receiving the coiled tape (10), and in that an opening, which may optionally be closable, is provided in the hub (21) of the coil for removing the coiled tape (10) from the spool.
- Use according to Patent Claim 13 of the tape according to Patent Claim 5, characterised in that a flat tool (28) is inserted between the spacers (16), lying one on top of the other, of both fastener parts for detaching the fastener parts (11, 12) from one another at the end of the coiled tape (10) remote from the hub, and in that the tool (28) and the circumference of the coil are moved relative to one another in the unwinding direction.
