Definitions
- the invention relates to an adhesive connection formed by two adhesive fastener parts, in which a first adhesive fastener part is provided on an active side of a film-shaped carrier with a plurality of hooking means protruding from the carrier, which have thickenings at the free ends of flexible stubble, which become during Press on the active side of a second fastener part with the same hooking means provided on it.
- European patent specification 37 652 discloses an adhesive connection of this type, in which the stubble on each fastener part is arranged at substantially equal distances from one another in each direction and in each direction the number of stubble present on a fastener part per unit length varies from the number of distinguishes stubble present on the other fastener part per unit length and does not form an integral multiple of this number in the other fastener part.
- the aim of this is to ensure that when shear forces acting parallel to the film-shaped carrier act on the adhesive connection, the two adhesive fastener parts cannot move relative to one another.
- this effect is in the known fastener parts not reached to the same extent in all places, so that when shear forces occur, the two fastener parts can twist against each other or even shift in some places.
- the invention has for its object to provide an adhesive connection in which the adhesive fastener parts cannot move against each other when shear forces parallel to the film-shaped carrier occur.
- the two fastener parts can not move against each other in the two directions mentioned even when shear forces occur. Since shear forces in other directions can be divided into two components that extend in the two directions mentioned, the two adhesive fastener parts can also are not displaced against each other by shear forces which act on the two adhesive fastener parts in the adhesive connection in directions deviating from the first or from the second direction.
- the distance of the grid lines from one another is at least as large as the sum of the thickness of a stubble of the first closure part and measured in the direction of this distance a thickening of the second closure part.
- the two directions mentioned form an acute angle with one another.
- the first direction is perpendicular to the second direction.
- the thickenings can be shaped differently in plan view.
- the cross section of the stubble can be shaped differently.
- the thickenings are round and the diameter of the thickening is approximately twice as large as the diameter of the essentially round cross section of the stubble. Hooking means of this type are known and are also referred to as "mushroom heads".
- Different shaped adhesive fastener parts can be produced by joining the repeats in different ways. However, it is expedient to arrange the repeats in such a way that the adhesive closure part is in the form of a band and the one, preferably the second, direction extends in the longitudinal direction of the band. Adhesive fastener parts of any length can then be cut off from such a tape, it then being irrelevant whether the interface is currently on a dividing line of two repeats or a repeat cuts through.
- the centers of the hooking means are arranged at every second crossing point of straight lines forming a grid, which are parallel to two mutually perpendicular directions and whose distances from one another are half as large as the distances from the grid lines of the first fastener part.
- each hooking means consists of a flexible stubble 13, which protrudes vertically from the film-shaped carrier and carries a mushroom-shaped round thickening 14 at its free end.
- the stubble 13 is round in cross section and has a diameter of 0.5 mm.
- the diameter of the thickening 14 arranged coaxially to the stubble 13 is 1 mm.
- the arrangement of the hooking means 11 in the repeat 10 is based on a grid which consists of two grid lines 15 extending parallel in a first direction, namely in the longitudinal direction of the repeat, and four parallel to one another, in one to the other first direction perpendicular second direction, namely the width direction of the repeat, extending raster line 16 is formed.
- These six grid lines intersect at eight crossing points 17 and thereby form four angles at each crossing point.
- At each crossing point 17 only one hooking means 11 is arranged such that each stubble 13 is arranged at an angle and thereby touches the two legs of the angle. As a result, each stubble 13 touches one of the two mutually perpendicular grid lines 15 and 16.
- each grid line 15 and 16 there is therefore a series of hooking means 11, the stubble 13 of which touch this grid line.
- the angles at which the hooking means 11 are located are selected such that in each of these rows touching a grid line 15 or 16, the hooking means are alternately on different sides of the grid line 15 or 16 concerned and for each pair of grid lines, for example 15, the stubble 13 touching a grid line 16 are arranged either on the sides facing away from one another or on the sides of the grid line 15 facing each other.
- FIG. 2 shows the top view of a section of a band in which the hooking means 11 are arranged after the repeat of FIG. 1, two repeats arranged alongside one another in the longitudinal and in the width direction being shown in this exemplary embodiment.
- an adhesive fastener part formed by a portion of this tape has a much larger number of repeats in both the length and width directions.
- the width direction of the repeat that is the horizontally extending direction in FIG. 2, as the longitudinal direction of the band, contrary to the impression resulting from FIG. 2.
- FIG. 4 shows the top view of the active side of a second adhesive fastener part, which forms a particularly good adhesive connection with the first adhesive fastener part.
- this second adhesive closure part is based on a grid which is formed from two sets of grid lines 25 and 26 which are parallel to one another, which are parallel to two mutually perpendicular directions and whose distances d 'are equal to one another. These distances d 'are half the distances d of the grid lines of the first adhesive fastener part.
- the hooking means 21 are arranged such that center points 27 of their plan view coincide with the crossing points of the grid lines 25 and 26, with a hooking means 21 being arranged on every grid line 25 and 26 only at every second crossing point.
- the distance b of the grid lines of the first closure part from each other in both directions is 1.81 mm. This is less than the sum of the double diameter of a stubble of the first adhesive fastener part and the simple diameter of a thickening of the second adhesive fastener part, which together gives 2 mm.
- any thickening of the second fastener part strikes the stubble of the first fastener part in an attempt to move it in a direction parallel to the two mutually perpendicular grid lines, these directions in which the stubble of the first fastener part stops form for the thickening of the second fastener part, are different with each thickening of the second fastener part.
- the two fastener parts are thereby secured against movements parallel to the carrier. It is therefore essential that the distances between the grid lines of the first closure part are smaller than the sum of the double thickness, measured in the direction of these distances, of a stubble of the first adhesive closure part and a thickening of the second adhesive closure part.
- the distance between the grid lines 15 and 16 of the first adhesive fastener part should be at least as large as the sum of the thickness of a stubble 13 of the first adhesive fastener part and a thickening 21 of the second adhesive fastener part measured in the direction of these distances.
Abstract
Description
Die Erfindung bezieht sich auf eine durch zwei Haftverschlußteile gebildete Haftverbindung, bei der ein erster Haftverschlußteil auf einer aktiven Seite eines folienförmigen Trägers mit einer Vielzahl von aus dem Träger vorstehenden Verhakungsmitteln versehen ist, die an den freien Enden von biegsamen Stoppeln Verdickungen aufweisen, die sich beim Andrücken an die aktive Seite eines zweiten Haftverschlußteils mit an diesem vorgesehenen gleichartigen Verhakungsmitteln verhaken.The invention relates to an adhesive connection formed by two adhesive fastener parts, in which a first adhesive fastener part is provided on an active side of a film-shaped carrier with a plurality of hooking means protruding from the carrier, which have thickenings at the free ends of flexible stubble, which become during Press on the active side of a second fastener part with the same hooking means provided on it.
Durch die europäische Patentschrift 37 652 ist eine Haftverbindung dieser Art bekannt, bei der die Stoppeln auf jedem Haftverschlußteil in jeder Richtung in im wesentlichen gleichen Abständen voneinander angeordnet sind und in jeder Richtung die Anzahl der auf einem Haftverschlußteil pro Längeneinheit vorhandenen Stoppeln sich von der Anzahl der auf dem anderen Haftverschlußteil pro Längeneinheit vorhandenen Stoppeln unterscheidet und kein ganzteiliges Vielfaches dieser Anzahl beim anderen Haftverschlußteil bildet. Dadurch soll erreicht werden, daß beim Einwirken von zum folienförmigen Träger parallelen Scherkräften auf die Haftverbindung die beiden Haftverschlußteile sich nicht gegeneinander verschieben können. Diese Wirkung wird jedoch bei den bekannten Haftverschlußteilen nicht an allen Stellen in gleichem Maße erreicht, so daß beim Auftreten von Scherkräften sich die beiden Haftverschlußteile gegeneinander verdrehen oder an manchen Stellen sogar verschieben können.European patent specification 37 652 discloses an adhesive connection of this type, in which the stubble on each fastener part is arranged at substantially equal distances from one another in each direction and in each direction the number of stubble present on a fastener part per unit length varies from the number of distinguishes stubble present on the other fastener part per unit length and does not form an integral multiple of this number in the other fastener part. The aim of this is to ensure that when shear forces acting parallel to the film-shaped carrier act on the adhesive connection, the two adhesive fastener parts cannot move relative to one another. However, this effect is in the known fastener parts not reached to the same extent in all places, so that when shear forces occur, the two fastener parts can twist against each other or even shift in some places.
Der Erfindung liegt die Aufgabe zugrunde, eine Haftverbindung zu schaffen, bei der die Haftverschlußteile beim Auftreten von zum folienförmigen Träger parallelen Scherkräften sich gegeneinander nicht bewegen können.The invention has for its object to provide an adhesive connection in which the adhesive fastener parts cannot move against each other when shear forces parallel to the film-shaped carrier occur.
Diese Aufgabe ist gemäß der Erfindung durch die Kombination der folgenden Merkmale gelöst:
- a) die Verhakungsmittel sind nach einem Rapport angeordnet, der sich in zwei zueinander senkrechten Richtungen beliebig oft wiederholt,
- b) jedem Rapport liegt ein Raster zugrunde, das von zwei einer ersten Richtung und von vier einer zweiten Richtung parallelen Rastergeraden gebildet ist, die sich in 2 x 4 = 8 Kreuzungspunkten schneiden und dadurch an jedem Kreuzungspunkt vier Winkel bilden,
- c) an jedem Kreuzungspunkt ist nur ein Verhakungsmittel so angeordnet, daß die Stoppeln neben jeder der ersten und zweiten Rastergeraden abwechselnd an verschiedenen Seiten der Rastergeraden liegen, und
- d) die Abstände der Rastergeraden voneinander sind gleich groß und jeder Abstand ist kleiner als die Summe der in Richtung dieses Abstandes gemessenen doppelten Dicke einer Stoppel des ersten Haftverschlußteiles und einer Verdickung des zweiten Haftverschlußteiles.
- a) the hooking means are arranged according to a repeat which is repeated as often as required in two mutually perpendicular directions,
- b) each repeat is based on a grid which is formed by two grid lines parallel to one another in a first direction and by four grid lines parallel to one another, which intersect at 2 x 4 = 8 crossing points and thereby form four angles at each crossing point,
- c) at each crossing point, only one hooking means is arranged such that the stubble next to each of the first and second grid lines lies alternately on different sides of the grid line, and
- d) the distances between the grid lines are equal and each distance is smaller than the sum of the double thickness, measured in the direction of this distance, of a stubble of the first fastener part and a thickening of the second fastener part.
Dadurch wird erreicht, daß die beiden Haftverschlußteile sich in den beiden genannten Richtungen auch beim Auftreten von Scherkräften nicht gegeneinander verschieben können. Da Scherkräfte in anderen Richtungen in zwei Komponenten aufgeteilt werden können, die sich in den beiden genannten Richtungen erstrecken, können die beiden Haftverschlußteile auch nicht durch Scherkräfte gegeneinander verschoben werden, die in von der ersten oder von der zweiten Richtung abweichenden Richtungen auf die beiden Haftverschlußteile in der Haftverbindung einwirken.This ensures that the two fastener parts can not move against each other in the two directions mentioned even when shear forces occur. Since shear forces in other directions can be divided into two components that extend in the two directions mentioned, the two adhesive fastener parts can also are not displaced against each other by shear forces which act on the two adhesive fastener parts in the adhesive connection in directions deviating from the first or from the second direction.
Damit die Verhakungsmittel nicht zu eng aneinander stehen und dadurch das Aneinaneinanderdrücken der beiden Haftverschlußteile behindert wird ist bei einer vorteilhaften Ausführungsform vorgesehen, daß der Abstand der Rastergeraden voneinander mindestens so groß ist wie die Summe der in Richtung dieses Abstandes gemessenen Dicke einer Stoppel des ersten Verschlußteiles und einer Verdickung des zweiten Verschlußteiles.So that the interlocking means are not too close to each other and thereby the pressing together of the two fastener parts is hindered, in an advantageous embodiment it is provided that the distance of the grid lines from one another is at least as large as the sum of the thickness of a stubble of the first closure part and measured in the direction of this distance a thickening of the second closure part.
In manchen Spezialfällen kann es vorteilhaft sein, wenn die beiden genannten Richtungen einen spitzen Winkel miteinander bilden. Bei einer vorteilhaften Ausführungsform ist jedoch vorgesehen, daß die erste Richtung senkrecht zur zweiten Richtung ist.In some special cases it can be advantageous if the two directions mentioned form an acute angle with one another. In an advantageous embodiment, however, it is provided that the first direction is perpendicular to the second direction.
Die Verdickungen können in der Draufsicht verschieden geformt sein. Auch kann der Querschnitt der Stoppeln verschieden geformt sein. Bei einer vorteilhaften Ausführungsform ist vorgesehen, daß die Verdickungen rund sind und der Durchmesser der Verdickung etwa doppelt so groß ist wie der Durchmesser des im wesentlichen runden Querschnitts der Stoppel. Verhakungsmittel dieser Art sind bekannt und werden auch als "Pilzköpfe" bezeichnet.The thickenings can be shaped differently in plan view. The cross section of the stubble can be shaped differently. In an advantageous embodiment it is provided that the thickenings are round and the diameter of the thickening is approximately twice as large as the diameter of the essentially round cross section of the stubble. Hooking means of this type are known and are also referred to as "mushroom heads".
Durch verschiedenes Aneinanderfügen der Rapporte können verschieden geformte Haftverschlußteile hergestellt werden. Zweckmäßig ist es jedoch, die Rapporte so anzuordnen, daß der Haftverschlußteil bandförmig ausgebildet ist und sich die eine, vorzugsweise die zweite Richtung in Längsrichtung des Bandes erstreckt. Von einem solchen Band können dann Haftverschlußteile beliebiger Länge abgeschnitten werden, wobei es dann nicht darauf ankommt, ob die Schnittstelle gerade an einer Trennlinie von zwei Rapporten liegt oder einen Rapport durchschneidet.Different shaped adhesive fastener parts can be produced by joining the repeats in different ways. However, it is expedient to arrange the repeats in such a way that the adhesive closure part is in the form of a band and the one, preferably the second, direction extends in the longitudinal direction of the band. Adhesive fastener parts of any length can then be cut off from such a tape, it then being irrelevant whether the interface is currently on a dividing line of two repeats or a repeat cuts through.
Bei einer vorteilhaften Ausführungsform ist vorgesehen, daß bei dem zweiten Haftverschlußteil die Mittelpunkte der Verhakungsmittel an jedem zweiten Kreuzungspunkt von ein Raster bildenden Geraden angeordnet sind, die zu zwei zueinander senkrechten Richtungen parallel sind und deren Abstände voneinander halb so groß sind wie die Abstände der Rastergeraden des ersten Haftverschlußteiles.In an advantageous embodiment it is provided that in the second fastener part, the centers of the hooking means are arranged at every second crossing point of straight lines forming a grid, which are parallel to two mutually perpendicular directions and whose distances from one another are half as large as the distances from the grid lines of the first fastener part.
Die Erfindung ist in der folgenden Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispieles im einzelnen erläutert:The invention is explained in detail in the following description of an embodiment shown in the drawing:
Es zeigen:

- Fig. 2

Die Fig. 1 und 2 zeigen in stark vergrößertem Maßstab die Draufsichten der aktiven Seite eines ersten Verschlußteiles, wobei in Fig. 1 nur der Teil der Draufsicht dargestellt ist, der einen Rapport 10 der Verteilung von Verhakungsmitteln 11 auf einem folienförmigen Träger 12 zeigt. Wie aus Fig. 3 ersichtlich ist, besteht jedes Verhakungsmittel aus einer biegesamen Stoppel 13, die senkrecht aus dem folienförmigen Träger vorsteht und an ihrem freien Ende eine pilzkopfförmige runde Verdickung 14 trägt. Die Stoppel 13 ist im Querschnitt rund und hat einen Durchmesser von 0,5 mm. Der Durchmesser der koaxial zur Stoppel 13 angeordneten Verdickung 14 beträgt 1 mm.1 and 2 show, on a greatly enlarged scale, the top views of the active side of a first closure part, only the part of the plan view being shown in FIG. 1, which shows a
Wie aus Fig. 1 ersichtlich ist, liegt der Anordnung der Verhakungsmittel 11 im Rapport 10 ein Raster zugrunde, das von zwei in einer ersten Richtung, nämlich in der Längsrichtung des Rapports, sich parallel erstreckenden Rastergeraden 15 und vier einander parallelen, sich in einer zur ersten Richtung senkrechten zweiten Richtung, nämlich der Breitenrichtung des Rapports, erstreckenden Rastergeraden 16 gebildet ist. Diese sechs Rastergeraden schneiden sich in acht Kreuzungspunkten 17 und bilden dadurch an jedem Kreuzungspunkt vier Winkel. An jedem Kreuzungspunkt 17 ist nur ein Verhakungsmittel 11 so angeordnet, daß jede Stoppel 13 in je einem Winkel angeordnet ist und dabei die beiden Schenkel des Winkels berührt. Dadurch berührt jede Stoppel 13 je eine der beiden zueinander senkrechten Rastergeraden 15 und 16. Längs jeder Rastergeraden 15 und 16 befindet sich also eine Reihe von Verhakungsmitteln 11, deren Stoppeln 13 diese Rastergerade berühren. Hierbei sind die Winkel, in denen sich die Verhakungsmittel 11 befinden, so ausgewählt, daß in jeder dieser eine Rastergerade 15 oder 16 berührenden Reihe die Verhakungsmittel sich abwechselnd an verschiedenen Seiten der betreffenden Rastergeraden 15 oder 16 befinden und bei jedem Paar von Rastergeraden z.B. 15, die eine Rastergerade 16 berührenden Stoppeln 13 entweder auf den einander abgekehrten Seiten oder auf den einander zugekehrten Seiten der Rastergeraden 15 angeordnet sind.As can be seen from FIG. 1, the arrangement of the
Die Abstände d der Rastergeraden 15 und 16 voneinander sind gleich. Dieser Abstand d beträgt bei dem dargestellten Ausführungsbeispiel 1,81 mm. Daraus ergibt sich ein Rapport mit der Länge a = 7,26 mm und der Breite b = 3,63 mm.The distances d between the
In Fig. 2 ist die Draufsicht eines Ausschnittes eines Bandes dargestellt, bei dem die Verhakungsmittel 11 nach dem Rapport nach Fig. 1 angeordnet sind, wobei bei diesem Ausführungsbeispiel je zwei in der Längs- und in der Breitenrichtung nebeneinander angeordnete Rapporte dargestellt sind. Natürlich weist ein Haftverschlußteil, der durch einen Abschnitt dieses Bandes gebildet ist, einen viel größere Anzahl von Rapporten sowohl in der Längs- als auch in der Breitenrichtung auf. Für die Herstellung des Bandes hat es sich als zweckmäßig erwiesen, als Längsrichtung des Bandes, entgegen dem sich aus Fig. 2 ergebenden Eindruck, die Breitenrichtung des Rapportes, also die in Fig. 2 sich waagerecht erstreckende Richtung zu wählen.FIG. 2 shows the top view of a section of a band in which the hooking means 11 are arranged after the repeat of FIG. 1, two repeats arranged alongside one another in the longitudinal and in the width direction being shown in this exemplary embodiment. Of course, an adhesive fastener part formed by a portion of this tape has a much larger number of repeats in both the length and width directions. For the production of the band, it has proven to be expedient to choose the width direction of the repeat, that is the horizontally extending direction in FIG. 2, as the longitudinal direction of the band, contrary to the impression resulting from FIG. 2.
In Fig. 4 ist die Draufsicht der aktiven Seite eines zweiten Haftverschlußteiles dargestellt, der mit dem ersten Haftverschlußteil eine besonders gute Haftverbindung bildet. Diesem zweiten Haftverschlußteil liegt für die Anordnung der Verhakungsmittel 21 ein Raster zugrunde, das aus zwei Scharen voneinander parallelen Rastergeraden 25 und 26 gebildet ist, die zu zwei zueinander senkrechten Richtungen parallel sind und deren Abstände d' voneinander gleich sind. Diese Abstände d' sind halb so groß wie die Abstände d der Rastergeraden des ersten Haftverschlußteiles. Bei diesem Ausführungsbeispiel sind die Verhakungsmittel 21 so angeordnet, daß Mittelpunkte 27 ihrer Draufsicht sich mit den Kreuzungspunkten der Rastergeraden 25 und 26 decken, wobei auf jeder Rastergeraden 25 und 26 immer nur an jedem zweiten Kreuzungspunkt ein Verhakungsmittel 21 angeordnet ist. Da bei dem zweiten Haftverschlußteil auf einer dem Rapport nach Fig. 1 entsprechenden Flächeneinheit in der ersten Richtung statt zwei doppelt so viele, also vier Rastergeraden und in der zweiten Richtung statt vier doppelt so viele, also acht Rastergeraden angeordnet sind, ergeben sich für die gleiche Flächeneinheit 32 Kreuzungspunkte, von denen nur die Hälfte mit Verhakungsmitteln besetzt sind, so daß der Anzahl von acht Verhakungsmitteln auf dem ersten Verschlußteil, sechzehn Verhakungsmittel auf dem zweiten Verschlußteil zugeordnet sind. Die Anzahl der Verhakungsmittel auf den beiden Verschlußteilen verhält sich also wie 1:2.FIG. 4 shows the top view of the active side of a second adhesive fastener part, which forms a particularly good adhesive connection with the first adhesive fastener part. For the arrangement of the hooking means 21, this second adhesive closure part is based on a grid which is formed from two sets of
Werden die beiden Haftverschlußteile mit ihren aktiven Seiten aneinandergedrückt, dann drängen sich die Verhakungsmittel 21 des zweiten Verschlußteiles zwischen die Verhakungsmittel 11 des ersten Verschlußteiles. Der Abstand b der Rastergeraden des ersten Verschlußteiles voneinander in beiden Richtungen beträgt je 1,81 mm. Das ist weniger als die Summe des doppelten Durchmessers einer Stoppel des ersten Haftverschlußteiles und des einfachen Durchmessers einer Verdickung des zweiten Haftverschlußteiles, was zusammen 2 mm ergibt. Der lichte Abstand der Stoppeln voneinander ist 1,81 mm minus des doppelten Durchmessers einer Stoppel = 1 mm, also nur 0,81 mm, was weniger ist als der Durchmesser einer Verdickung des zweiten Haftverschlußteiles, nämlich weniger als 1 mm. Das hat zur Folge, daß jede Verdickung des zweiten Haftverschlußteiles bei einem Versuch, sie in jeweils einer Richtung parallel zu den beiden einander senkrechten Rastergeraden zu bewegen, an die Stoppeln des ersten Verschlußteiles anstößt, wobei diese Richtungen, in denen die Stoppeln des ersten Verschlußteiles Anschläge für die Verdickung des zweiten Haftverschlußteils bilden, bei jeder Verdickung des zweiten Haftverschlußteiles verschieden sind. Die beiden Haftverschlußteile sind dadurch gegen Bewegungen parallel zu dem Träger gesichert. Es kommt also im wesentlichen darauf an, daß die Abstände der Rastergeraden des ersten Verschlußteils voneinander kleiner sind als die Summe der in Richtung dieser Abstände gemessenen doppelten Dicke einer Stoppel des ersten Haftverschlußteils und einer Verdickung des zweiten Haftverschlußteiles.If the two adhesive fastener parts are pressed against one another with their active sides, then the hooking means 21 of the second locking part press between the hooking means 11 of the first locking part. The distance b of the grid lines of the first closure part from each other in both directions is 1.81 mm. This is less than the sum of the double diameter of a stubble of the first adhesive fastener part and the simple diameter of a thickening of the second adhesive fastener part, which together gives 2 mm. The clear distance between the stubble is 1.81 mm minus twice the diameter of a stubble = 1 mm, i.e. only 0.81 mm, which is less than the diameter of a thickening of the second adhesive fastener part, namely less than 1 mm. As a result, any thickening of the second fastener part strikes the stubble of the first fastener part in an attempt to move it in a direction parallel to the two mutually perpendicular grid lines, these directions in which the stubble of the first fastener part stops form for the thickening of the second fastener part, are different with each thickening of the second fastener part. The two fastener parts are thereby secured against movements parallel to the carrier. It is therefore essential that the distances between the grid lines of the first closure part are smaller than the sum of the double thickness, measured in the direction of these distances, of a stubble of the first adhesive closure part and a thickening of the second adhesive closure part.
Eine zu dichte Anordnung der Verhakungsmittel des ersten Haftverschlußteiles in Bezug auf die entsprechende Dicke der Verdickung des zweiten Haftverschlußteiles könnte dazu führen, daß das Eindringen der Verdickungen 21 des zweiten Haftverschlußteiles zwischen die Verdickungen des ersten Haftverschlußteiles behindert wird. Aus diesem Grunde sollte der Abstand der Rastergeraden 15 und 16 des ersten Haftverschlußteiles voneinander mindestens so groß sein, wie die Summe der in Richtung dieser Abstände gemessenen Dicke einer Stoppel 13 des ersten Haftverschlußteiles und einer Verdickung 21 des zweiten Haftverschlußteiles. Beim dargestellten Ausführungsbeispiel ist dieser Abstand b = 1,81 mm größer als die Summe des Durchmessers einer Stoppel = 0,5 mm und einer Verdickung des Verhakungsmittels 21 des zweiten Haftverschlußteiles = 1 mm, nämlich 1,81 mm > 1,5 mm.A too tight arrangement of the hooking means of the first fastener part with respect to the corresponding thickness of the thickening of the second fastener part could lead to the penetration of the
Die im vorstehenden angegebenen Abmessungen sind die Abmessungen eines vorteilhafte Ausführungsbeispiels, diese Abmessungen können ganz andere Größen haben. Wesentlich ist, daß die Größenverhältnisse stimmen, wie sie oben angegeben und in den Ansprüchen beansprucht sind.The dimensions given above are the dimensions of an advantageous embodiment, these dimensions can have completely different sizes. It is essential that the proportions are correct, as stated above and claimed in the claims.
