Description

Die Erfindung betrifft eine Bodenbelag-Warenbahn mit einer einen Pol aufweisenden Oberseite und einer mindestens teilweise mit einer Beschichtungsmasse versehenen Unterseite. Insbesondere befaßt sich die Erfindung mit sogenannten künstlichen Rasen für Sportfelder und dergleichen.The invention relates to a floor covering material web with an upper side having a pole and an underside at least partially provided with a coating material. In particular, the invention is concerned with so-called artificial turf for sports fields and the like.

Bekannte derartige Warenbahnen besitzen einen gewebten, gewirkten oder gestrickten textilen Grundträger, in dem die Polfäden verankert sind und dessen Unterseite ganz oder teilweise mit einer weichelastischen Beschichtungsmasse, insbesondere Weich-PVC, versehen ist. Bei nur partieller Rückenbeschichtung des textilen Grundträgers zur besseren Fixierung der Polfäden ist es auch bekannt, den mit dem Pol versehenen textilen Grundträger auf einer Unterlage zu befestigen, welche im wesentlichen aus einer mit einer Beschichtungsmasse überzogenen textilen Kernlage besteht, wobei es sich auch in diesem Fall bei der Beschichtungsmasse insbesondere um Weich-PVC handelt. Diese Unterlage kann eine vollständig geschlossene Schicht bilden oder vertikale Durchlässe definierende Öffnungen besitzen.Known webs of this type have a woven, knitted or knitted textile base support, in which the pile threads are anchored and the underside of which is wholly or partly provided with a flexible coating material, in particular soft PVC. In the case of only partial back coating of the textile base support for better fixing of the pile threads, it is also known to fasten the textile base support provided with the pile on a base, which essentially consists of a textile core layer covered with a coating material, which is also the case in this case the coating composition is in particular soft PVC. This document can be a completely closed one Form a layer or have openings defining vertical passages.

Besonders für Sportstätten wird neuerdings die Forderung erhoben, einen in Rede stehenden Bodenbelag leicht anbringen und wieder entfernen zu können, zum Beispiel um zu einer gewissen Zeit eine erste Sportart auf einem Hartbelag ausüben zu können, zu einer anderen Zeit aber auf einem rasenähnlichen Bodenbelag Fußball, Hockey oder dergleichen zu spielen.Especially for sports facilities, the requirement has recently been raised to be able to easily attach and remove a floor covering in question, for example in order to be able to practice a first type of sport on a hard surface at a certain time, but at another time football on a grass-like floor covering, To play hockey or the like.

Diese Forderung läßt sich nun erfindungsgemäß mit Bodenbelag-Warenbahnen der eingangs erwähnten Art dann erfüllen, wenn bei diesen Warenbahnen zumindest längs einer Kante in einem streifenförmigen Bereich die Dicke der Beschichtungsmasse geringer gehalten wird als in dem angrenzenden Warenbahnbereich, wenn ferner in dem streifenförmigen Bereich ein erstes Element eines aus Flauschband und Hakenband bestehenden Klettenverschlusses befestigt wird und wenn schließlich das zweite Element des Klettenverschlusses zum Verbinden zweier aneinander benachbarter Warenbahnen vorgesehen ist. Zum Belegen eines Sportfelds mit einem künstlichen Rasen werden dann einfach die Warenbahnen nebeneinander und aneinanderstoßend verlegt und mit den bekannten sogenannten Klettenverschlüssen miteinander verbunden, so daß sie sich zum Entfernen des künstlichen Rasens wieder leicht voneinander lösen und aufrollen lassen.This requirement can now be met, according to the invention, with flooring material webs of the type mentioned at the outset if the thickness of the coating composition is kept smaller at least along one edge in a strip-shaped area than in the adjacent material web area, if a first in the strip-shaped area Element of a Velcro tape and hook tape is attached Velcro and when the second element of the Velcro is finally provided for connecting two adjacent webs. To cover a sports field with an artificial turf, the webs are simply laid side by side and abutting and connected with the known so-called Velcro fasteners, so that they can be easily detached from each other and rolled up to remove the artificial turf.

Bei den sogenannten Flauschbändern der bekannten Klet- tenverschlüs'se handelt es sich um nach Art eines Henkelplüschs ausgebildete textile Bänder, in deren Plüschhenkeln sich die aufrecht stehenden Polelemente der Hakenbänder verfangen, wenn man Haken-und Flauschband gegeneinander drückt. Bei den Polelementen der Hakenbänder handelt es sich um Abschnitte von steifen Kunststoffäden, die an ihren oberen, freien Enden haken- oder pilzkopfförmig ausgebildet sind.The so-called fleece tapes of the well-known Velcro fasteners are textile tapes designed in the manner of a handle plush, in the plush handles of which the upright pole is located Elements of the hook straps get caught when you press the hook and loop straps against each other. The pole elements of the hook straps are sections of stiff plastic threads that are designed in the shape of hooks or mushrooms at their upper, free ends.

Wenn vorstehend von Flausch- und Hakenband die Rede ist, so sollen hierunter natürlich auch kurze Bandabschnitte verstanden werden, die in Abständen voneinander an den Warenbahnkanten angebracht werden.If we are talking about fleece and hook tape above, this should of course also be understood to mean short tape sections which are attached to the web edges at intervals from one another.

Um eine völlig ebene Oberfläche des Bodenbelags zu erzielen, entspricht bei einer bevorzugten Ausfüh- rungsform der Erfindung die Höhe der von den genannten streifenförmigen Bereich gebildeten Aussparung zumindest ungefähr der Dicke des Klettenverschlusses.In order to obtain a completely flat surface of the floor covering, corresponds, in a preferred exporting - the thickness approximately of the invention, the height of the recess formed by the said strip-shaped region is at least approximately of the velcro fastening.

Prinzipiell kann das eine der beiden Elemente eines Klettenverschlusses in beliebiger Weise an der Warenbahn befestigt werden. Da die üblicherweise verwendeten Beschichtungsmassen aber auch gute Kleber bilden, empfiehlt es sich, bei der Herstellung der erfindungsgemäßen Warenbahn das eine Element des Klettenverschlusses auf die Unterseite der Warenbahn aufzulegen, solange sich die Beschichtungsmasse noch nicht verfestigt hat, d.h. bei einer bevorzugten Ausführungsform der erfindungsgemäßen Warenbahn ist das erste Element des Klettenverschlusses durch die Beschichtungsmasse mit der Warenbahn verklebt. Da besonders vorteilhafte Beschichtungsmassen unter Wärmeeinwirkung und/oder Wärmeentwicklung polymerisieren oder kondensieren, empfiehlt es sich ferner, das gegen eine solche Wärmeeinwirkung unempfindliche Flauschband des Klettenverschlusses mit der Warenbahn zu verkleben.In principle, one of the two elements of a Velcro fastener can be attached to the web in any way. However, since the coating compositions usually used also form good adhesives, it is advisable to place one element of the Velcro fastener on the underside of the web during the manufacture of the fabric web as long as the coating material has not yet solidified, ie in a preferred embodiment of the fabric web according to the invention the first element of the Velcro fastener is glued to the web by the coating compound. Since particularly advantageous coating compositions polymerize or condense under the influence of heat and / or heat, it is also advisable to to glue the Velcro fastener of the Velcro fastener, which is insensitive to such heat, to the product web.

Bei der Herstellung der eingangs erläuterten bekannten Bodenbeläge mit einer Unterlage wird deren textile Kernlage durch Tauchen mit der Beschichtungsmasse überzogen. In diesem Fall läßt sich die genannte Aussparung besonders einfach dadurch erzeugen, daß die Beschichtungsmasse vor ihrer Verfestigung in dem streifenförmigen Bereich zumindest teilweise wieder entfernt, insbesondere mit Hilfe eines Rakels oder dergleichen. abgestreift wird. Auf diese Weise kann man sich ein nachträgliches Abfräsen oder dergleichen ersparen.In the production of the known floor coverings with an underlay, the textile core layer is coated with the coating composition by dipping. In this case, the above-mentioned recess can be produced particularly simply by at least partially removing the coating composition before it solidifies in the strip-shaped region, in particular with the aid of a doctor blade or the like. is stripped. In this way, subsequent milling or the like can be saved.

Durch die Erfindung wurde ferner ein besonders einfaches Verlegeverfahren geschaffen, bei dem die Warenbahnen mit an ihren Längskanten angebrachten ersten Klettenverschluß-Elementen aneinanderstoßend ausgelegt werden, worauf die einander benachbarten Längskantenbereiche zweier Warenbahnen, vom einen Ende der Warenbahnen beginnend, über jeweils eine kurze Strecke angehoben und nach oben umgebogen werden, und wobei ferner, an dem genannten Ende beginnend, das bandförmige zweite Klettenverschluß-Element von oben her in den so geöffneten Spalt zwischen den Warenbahnen eingeführt und unter diesen abgelegt wird, worauf die Längskantenbereiche der beiden Warenbahnen auf das zweite Klettenverschluß-Element abgesenkt und über dieses miteinander verbunden werden. Dieses Verfahren läßt sich am einfachsten durch ein Gerät ausführen, das erfindungsgemäß durch ein pflugscharähnliches Werkzeug zum Öffnen des Spalts zwischen zwei einander benachbarten Warenbahnen, eine Aufnahme für einen Vorrat des zweiten Klettenverschluß-Elements sowie ein inbesondere als drehbar gelagerte Rolle ausgebildetes, unmittelbar über der Unterkante des Werkzeugs angeordnetes Umlenkelement für das zweite Klettenverschluß-Element gekennzeichnet ist. Man braucht dann nur das eine Band des Klettenverschlusses, insbesondere das Hakenband, am Ende zweier miteinander zu verbindenden Warenbahnen zu befestigen, zum Beispiel am Untergrund anzunageln, worauf mit dem Gerät der Stoßstelle zwischen den beiden einander benachbarten Warenbahnen entlanggefahren und dabei gleichzeitig das Hakenband unter den beiden Warenbahnen ausgelegt wird, so daß nach dem Zurückfallen der Längskantenbereiche auf das Hakenband die beiden Warenbahnen durch das Hakenband miteinander verbunden sind.The invention also provides a particularly simple laying method in which the webs are designed to be abutted with first Velcro fastener elements attached to their longitudinal edges, whereupon the adjacent longitudinal edge regions of two webs, starting from one end of the webs, are each raised over a short distance and are bent upwards, and further, starting at the end mentioned, the band-shaped second Velcro fastener element is inserted from above into the gap between the webs and opened underneath them, whereupon the longitudinal edge regions of the two webs onto the second Velcro fastener. Element lowered and connected to each other via this. This method can be carried out most simply by a device which, according to the invention, uses a ploughshare-like tool to open the gap between two mutually adjacent material webs, a receptacle for a supply of the second Velcro fastener element, and a deflection element for the second Velcro fastener element, which is designed in particular as a rotatably mounted roller and is arranged directly above the lower edge of the tool, is characterized. You then only need to fasten one strap of the Velcro fastener, in particular the hook strap, at the end of two webs to be connected to one another, for example nailing it to the ground, whereupon the device travels along the joint between the two adjacent webs and at the same time the hook strap under the two material webs is designed so that akenband to H after the dropping back of the longitudinal edge regions of the two material webs are joined together by hook tape.

Das in Fig. 1 gezeigte Stück eines künstlichen Rasens 1o weist einen insbesondere gewirkten textilen Grundträger 12 auf, in dem aus Kunststoff extrudierte Polbändchen 14 verankert sind. Durch die Verankerung der Polbändchen im Grundträger 12 auf dessen Unterseite entstandene rippenförmige Vorsprünge wurden mit einer Rückenbeschichtungsmasse 14 beschichtet, um die Polbändchen 14 im Grundträger 12 sicher zu befestigen. Die Rückenbeschichtungsmasse 14 besteht zweckmäßigerweise aus thermoplastischen Material und insbesondere aus Weich-PVC. Zwischen den beschichteten Rippen bleibt das lockere Gewirke des Grundträgers 12 also wasserdurchlässig.The piece of an artificial lawn 10 shown in FIG. 1 has an in particular knitted textile base support 12, in which pole strips 14 extruded from plastic are anchored. By anchoring the pole ribbons in the base support 12 on its underside, rib-shaped projections were coated with a backing coating 14 in order to securely fix the pole ties 14 in the base support 12. The back coating mass 14 suitably consists of thermoplastic Ma material and especially from soft PVC. The loose knitted fabric of the base support 12 thus remains permeable to water between the coated ribs.

Das in Fig. 2 gezeigte Stück einer elastischen und gleichfalls wasserdurchlässigen Unterlage 2o besitzt eine textile Kernlage aus Kernfäden 22; welche mit einem geschäumten thermoplastischen Material, insbesondere geschäumten Weich-PVC 24 überzogen ist. Dieser Überzug bildet an der Unterseite der Unterlage 2o noppenförmige Vorsprünge 26, zwischen denen sich in vertikaler Richtung durchgehende Öffnungen 28 befinden.The piece of an elastic and also water-permeable base 20 shown in FIG. 2 has a textile core layer made of core threads 22; which is covered with a foamed thermoplastic material, in particular foamed soft PVC 24. This coating forms on the underside of the base 2o knob-shaped projections 26, between which there are openings 28 in the vertical direction.

Die Fig. 3 zeigt eine Draufsicht auf ein Stück des textilen Kerns 3o der Unterlage 20, bei dem es sich erfindungsgemäß um eine Raschelware handelt, bei der zwischen von den Fäden 22 gebildeten Maschenreihen 32 im Abstand voneinander angeordnete Felder 34 liegen, in denen Kunststoffbändchen 36 zickzackförmig zwischen den Maschenreihen 22 hin- und hergeführt sind. Taucht man eine solche Struktur in eine flüssige Kunststoffmasse, die später zum Beispiel unter Wärmeeinwirkung verfestigt werden kann, und spannt die so hergestellte Unterlage waagerecht auf, so bilden sich auf ihrer Unterseite von selbst die in Fig. 2 gezeigten noppenförmigen Vorsprünge 26. Das beschriebene erfindungsgemäße Herstellungsverfahren führt also besonders einfach zu der in Fig. 2 gezeigten Struktur.Fig. 3 shows a plan view of a piece of the textile core 3o of the base 2 0 , which according to the invention is a Raschelware, in which there are fields 34, spaced apart from one another, between rows of stitches 32 formed by the threads 22, in which plastic bands 36 are guided back and forth between the rows of stitches 22 in a zigzag shape. If one dips such a structure into a liquid plastic mass, which can later be solidified, for example, under the influence of heat, and stretches the base produced in this way horizontally, the knob-shaped projections 26 shown in FIG. 2 automatically form on its underside Manufacturing process thus leads particularly simply to the structure shown in FIG. 2.

Die Fig. 4 zeigt ein Stück einer modifizierten Unterlage 20' mit noppenförmigen Vorsprüngen 26' und Öffnungen 28', die sich von der Ausführungsform nach Fig. 2 nur dadurch unterscheidet, daß auf der Oberseite der Unterlage 20' erfindungsgemäß wulstartige Vorsprünge 29' die Öffnungen 28' umgeben, so daß sich zwischen diesen wulstartigen Vorsprüngen wannenförmige Vertiefungen 27' ergeben. Die wulstartigen Vorsprünge 29' lassen sich durch eine leichte Modifikation des erfindungsgemäßen Herstellungsverfahrens für die in Rede stehenden Unterlagen leicht erzielen, da man einfach das noch nicht verfestigte Überzugsmaterial veranlassen muß, über die Ränder der Felder 34 (siehe Fig. 3) geringfügig hinauszufließen, gegebenenfalls im Zuge des Aufschäumens des Überzugsmaterials.Fig. 4 shows a piece of a modified base 2 0 'with knob-shaped projections 26' and openings 28 ', which differs from the embodiment of FIG. 2 only in that on the upper side of the base 2 0 'according to the invention bead-like projections 29', the openings 28 'is surrounded, so that between these bead-like projections trough-shaped recesses 27' result. The bead-like projections 29 'can easily be achieved by a slight modification of the manufacturing method according to the invention for the documents in question, since one simply has to cause the as yet unconsolidated covering material to flow slightly beyond the edges of the fields 34 (see FIG. 3), if necessary in the course of foaming the coating material.

Die Fig. 6 zeigt einen Querschnitt durch kleine Teilstücke der bandförmigen Bestandteile eines bekannten sogenannten Klettenverschlusses. Mit 5o wurde das sogenannte Flauschband, mit 52 das sogenannte Hakenband bezeichnet. Beide besitzen einen meist mit Kunststoff beschichteten oder kaschierten, bandförmigen textilen Grundträger 54 bzw. 56, in dem beim Flauschband 5o Flüschhenkel 58 verankert sind, während im Grundträger 56 des Hakenbands 52 Anker 6o mit pilzkopfförmigen freien Enden befestigt sind, die aus verhältnismäßig steifen Kunststoffäden bestehen.6 shows a cross section through small sections of the band-shaped components of a known so-called Velcro fastener. The so-called loop tape was designated with 5o, the so-called hook tape with 52. Both have a mostly plastic-coated or laminated, band-shaped textile base support 54 or 56, in which 5o tufted handles 58 are anchored in the loop tape, while anchors 6o are fastened in the base support 56 of the hook tape 52 with mushroom-shaped free ends, which consist of relatively stiff plastic threads .

Der in Fig. 5 dargestellte Schnitt durch die einander zugekehrten Längsrandbereiche zweier nebeneinander verlegter Bodenbelag-Warenbahnen 7o und 72 läßt erkennen, daß jede dieser Warenbahnen aus einem künstlichen Rasen 1o und einer Unterlage 2o besteht, deren Oberseite mit der Unterseite des künstlichen Rasens in geeigneter Weise verbunden ist, beispielsweise durch Kleben oder Verschweißen der Rückenbeschichtungsmasse 14 des künstlichen Rasens mit dem Überzug 24 der Unterlage 20. In an die Stoßstelle 74 der beiden Warenbahnen 70, 72 angrenzenden streifenförmige Bereichen 76 der Unterlage 2o der beiden Warenbahnen wurde die Weich-PVC-Masse des Überzugs 24 auf der Unterseite teilweise entfernt, so daß streifenförmige Aussparungen 78 entstehen, in denen jeweils ein Flauschband 5o mit nach unter gekehrten Plüschhenkeln befestigt ist. Diese beiden Flauschbänder und damit die Warenbahnen 7o und 72 lassen sich dann durch ein die Stoßstelle 74 überbrückendes Hakenband 52 miteinander verbinden, wobei diese Verbindung erfindungsgemäß leicht wieder lösbar ist. Die Fig. 5 läßt auch erkennen, daß der erfindungsgemäß verwendete Klettenverschluß 50, 52 dank der Aussparungen 78 nicht aufträgt, so daß sich die Warenbahnen 7o und 72 im Bereich der Stoßstelle 74 nicht nach oben wölben.The two in Fig. Section 5 represented by the facing longitudinal edge portions adjacent laid flooring webs 7o and 72 reveals that each of these webs composed of an artificial turf 1o and a base 2o, the upper face suitable to that of the artificial R Asens bottom in Is connected, for example by gluing or welding the back coating 14 of the artificial turf to the Cover 24 of document 2 0 . In the joint 74 of the two webs 7 0, 72 adjacent strip-shaped regions 76 has the base 2o of the two webs of the plasticized PVC composition of the coating 24 on the underside is partially removed so that strip-shaped recesses are formed 78, in each of which a fleece 5o is attached with plush handles swept under. These two fleece tapes and thus the webs 7o and 72 can then be connected to one another by a hook tape 52 bridging the joint 74, this connection being easily detachable according to the invention. 5 also shows that the Velcro fastener 5 0 , 52 used according to the invention does not bulge thanks to the cutouts 78, so that the webs 7o and 72 do not bulge upward in the region of the joint 74.

Die Fig. 7 zeigt die beiden Warenbahnen 7o und 72 schräg von oben, nachdem sie aneinanderstoßend auf dem Boden ausgelegt wurden. Ferner zeigt diese Fig. ein Hilfsgerät für das Verbinden der erfindungsgemäßen Warenbahnen, welches ein Führungsgestell 100 besitzt, an dem eine Achse lo2 zum Tragen eines Hakenbandvorrats 104 sowie unten eine Art Pflugschar lo6 befestigt sind. Unmittelbar über der Pflugschar ist außerdem im Führungsgestell 100 eine Umlenkrolle lo8 für das Hakenband 52 drehbar gelagert.Fig. 7 shows the two webs 7o and 72 obliquely from above after they have been laid together on the floor. Furthermore, this Figure shows. An auxiliary device for connecting the webs of the invention, which has a guide frame 100 are fixed to the an axis lo2 for supporting a akenbandvorrats H 1 0 4 and below a kind of ploughshare lo6. Immediately above the ploughshare, a guide roller lo8 for the hook band 52 is also rotatably mounted in the guide frame 100.

Erfindungsgemäß ist die Pflugschar 106 so ausgebildet, daß sich mit ihr die Stoßstelle 74 der beiden Warenbahnen 70, 72 so öffnen läßt, wie dies in Fig. 7 dargestellt ist. Zwischen die durch die Pflugschar nach oben gewölbten und nach der Seite zu auseinandergedrängten Längskantenbereiche der Warenbahnen 7o und 72 läßt sich auf diese Weise das Hakenband 52 einführen und so unter den Warenbahnen ablegen. Wenn man also mit dem Einlegen des Hakenbands am einen Ende der beiden Warenbahnen 7o und 72 beginnt und dort das freie Ende des Hakenbands befestigt, so wird dieses beim Hindurchfahren durch die Stoßstelle 74 in Warenbahnlängsrichtung abgerollt und unter den Flauschbändern 5o der beiden Warenbahnen abgelegt. Wenn die Längskantenbereiche der beiden Warenbahnen hinter dem im Fig.7 gezeigten Gerät dann wieder auf das Hakenband herabfallen und von der Bedienungsperson des Verlegegeräts betreten werden, erfolgt eine hinreichend feste Verbindung von Flauschbändern und Hakenband und damit der beiden aneinanderstoßenden Warenbahnen 70, 72.According to the ploughshare 1 0 6 is designed so that the joint 74 of the two webs 7 0 , 72 can be opened with it, as shown in Fig. 7. Between the bulging upwards through the ploughshare and to the side apart The crowded longitudinal edge areas of the webs 7o and 72 can be inserted in this way, the hook tape 52 and thus placed under the webs. So if you start inserting the hook tape at one end of the two webs 7o and 72 and fasten the free end of the hook tape there, it is rolled off in the longitudinal direction of the web as it passes through the joint 74 and placed under the fleece tapes 5o of the two webs. When the longitudinal edge portions of the two webs then again fall behind that shown in the Figure 7 device to the hook tape and be entered by the operator of the installation device is carried out, a sufficiently firm connection of knit loops and hook tape, and thus the two abutting webs 7 0., 72

Die Warenbahnen können auf einem entsprechenden Untergrund lose verlegt werden. Mit Hilfe auf ihrer Unterseite mit einem Selbstkleber beschichteter Hakenbänder läßt sich aber auch eine Verbindung zwischen den Warenbahnen und dem Untergrund erreichen. Die Vorschubrichtung des Verlegegeräts wurde in Fig. 7 mit einem Pfeil gekennzeichnet.The material webs can be laid loosely on a suitable surface. With the help of hook tapes coated with a self-adhesive on their underside, a connection between the material webs and the substrate can also be achieved. The direction of advance of the laying device was marked with an arrow in FIG. 7.

Die am unteren Ende des Gestells 100 befestigte Pflugschar lo6 hat in der Ansicht von vorn die Gestalt eines gleichschenkligen Dreiecks mit konkaven Seiten, wobei die von der Spitze dieses 'Dreiecks definierte obere Längskante der Pflugschar in Fig. 7 mit 106 a bezeichnet wurde. Die Pflugschar endet vor der Umlenkrolle lo8 und läßt einen Spalt für den Durchtritt des Hakenbands 52 frei, und es versteht sich von selbst, daß die Stoßstelle 74 durch die Pflugschar nur so weit geöffnet werden muß, daß das Führungsgestell 100 mit der Umlenkrolle 108 in den geöffneten Spalt hineinpaßt.The ploughshare lo6 fastened to the lower end of the frame 100 has the shape of an isosceles triangle with concave sides in the view from the front, the upper longitudinal edge of the ploughshare defined by the tip of this ' triangle being designated in FIG. 7 with 1 0 6 a. The ploughshare ends in front of the deflection roller lo8 and leaves a gap for the passage of the hook band 52, and it understands it goes without saying that the joint 74 must only be opened so far by the ploughshare that the guide frame 100 with the deflection roller 1 0 8 fits into the open gap.
