Abstract

In a novel method, a self-attaching or sealing sheet (21) is made. This has a number of projections (5) for interlocking, which include a stem and mushroom-like head, each broadly resembling a press-stud, and are formed integrally with their substrate (19). Fluid or plasticised thermoplastic is supplied into the gap (17) between pressure- (15) and moulding- (1) rollers. The moulding roller includes depressions. The rollers turn in opposite directions, thus forming the substrate in the gap between them. An additional band (7) of soluble material is fed to the moulding roller. This has through-holes (9) forming cavities, their locations matching those of the depressions (3) in the moulding roller. Also claimed is the closure section and a closure, made as described.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Haftverschlußteiles mit einer Vielzahl von einstückig mit einem Träger ausgebildeten Verhakungsmitteln in Form von Verdickungen aufweisenden Stengeln, bei dem ein thermoplastischer Kunststoff in plastischem oder flüssigem Zustand dem Spalt zwischen einer Druckwalze und einer Formwalze zugeführt wird, wobei die Formwalze mit Vertiefungen versehen ist und beide Walzen in entgegengesetztem Drehsinn angetrieben werden, so daß der Träger im Spalt zwischen den Walzen gebildet wird. Die Erfindung betrifft auch ein Haftverschlußteil, das nach diesem Verfahren hergestellt worden ist, sowie einen Haftverschluß, der zumindest aus einem solchen Haftverschlußteil besteht.The invention relates to a method for producing an adhesive fastener part with a plurality of hooking means formed in one piece with a carrier in the form of thickened stems, in which a thermoplastic Plastic in the plastic or liquid state the gap between a pressure roller and a forming roller is fed, the Forming roller is provided with depressions and both rollers in opposite directions Direction of rotation are driven so that the carrier in the gap between the Rolling is formed. The invention also relates to an adhesive fastener part has been produced by this method, and an adhesive fastener, the at least consists of such a fastener part.

Ein solches Verfahren ist aus dem Stand der Technik insbesondere durch die US 5.077.870 der Minnesota Mining and Manufacturing Company bekannt. Bei diesem bekannten Verfahren werden die Stengel der Verhakungsmittel durch zylindrisch geformte Hohlräume der Formwalze gebildet. Die so gebildeten Stengel müssen dann in einem nachgeschalteten Arbeitsgang durch ein weiteres Walzenpaar bearbeitet werden, um die Verdickungen der Verhakungsmittel auszubilden. Außerdem müssen die Hohlräume der Formwalze auf eine definierte Temperatur gekühlt werden.Such a method is known from the prior art in particular through the US 5,077,870 to Minnesota Mining and Manufacturing Company. At In this known method, the stems of the hooking means are removed cylindrically shaped cavities of the forming roll are formed. The so educated Stems then have to go through another in a subsequent operation A pair of rollers are machined to thicken the interlocking means to train. In addition, the cavities of the forming roll must be defined Temperature can be cooled.

Durch die US 5.242.646 ist des weiteren bekannt, eine Spritzgußform zu verwenden, die sich aus einer Basisform zusammensetzt, in welcher der Träger gebildet wird, auf die eine Stengelform aus einem wasserlöslichen Material folgt und bei der zuletzt zur Ausbildung der Verdickungen der Verhakungsmittel eine Kopfform aufgesetzt wird. Im Bereich der Kopfform wird daher ein Durchlaß angebracht, durch den ein beispielsweise polymeres Material in die zusammengesetzte Form einfließen kann. Diese Form der Herstellung eines Haftverschlußteiles erfordert viele Arbeitsgänge, da jeweils die Gußform zusammengesetzt mit dem polymeren Material gefüllt und anschließend die verschiedenen Formteile wieder voneinander getrennt werden müssen. In einem weiteren Arbeitsgang wird dann das auflösbare Material entfernt. Dadurch ist dieses Herstellungsverfahren sehr zeit- und kostenaufwendig.From US 5,242,646 is also known to an injection mold use, which is composed of a basic form in which the carrier is formed, on the stem form of a water-soluble material follows and at the last to form the thickening of the hooking means a head shape is put on. Therefore, in the area of the head shape Passage attached through which, for example, a polymeric material in the compound form can flow. This form of making one The fastener part requires many operations, since the mold is assembled filled with the polymeric material and then the different molded parts must be separated from each other again. In the dissolvable material is then removed in a further operation. Thereby this manufacturing process is very time consuming and costly.

Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein weniger aufwendiges und damit zugleich kostengünstigeres Verfahren zur Herstellung von Haftverschlußteilen bereitzustellen, daß zudem die kontinuierliche Herstellung solcher Haftverschlußteile ermöglicht.Based on this prior art, the present invention The task is based on a less complex and therefore less expensive Process for the production of adhesive fastener parts to provide that also enables the continuous production of such fastener parts.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruches 1. Dadurch, daß der Formwalze zusätzlich ein Band aus auflösbarem Material zugeführt wird, das Hohlräume aufweist, deren Position an die Lage der Vertiefungen der Formwalze angepaßt ist, fließt der thermoplastische Kunststoff sowohl in die Hohlräume des auflösbaren Materials als auch in die Vertiefungen der Formwalze. Durch eine solche Anordnung wird der Träger und werden die Stengel im Spalt zwischen den Walzen gebildet. Die Trägerdicke ergibt sich aus dem Spalt zwischen der Druck- und der Formwalze, der nicht von dem Band aus auflösbarem Material ausgefüllt wird. Sie ist daher beliebig und je nach Einsatzzweck des so herzustellenden Haftverschlußteiles bestimmbar. Durch diese Herstellungsweise entfällt eine Nachbearbeitung durch ein weiteres Walzenpaar. Da das Band aus auflösbarem Material in Form eines Endlosbandes zugeführt werden kann, ist ein kontinuierliches und damit zeit- und kostengünstiges Herstellungsverfahren möglich.This object is achieved by the features of claim 1. that the form roller additionally fed a strip of dissolvable material is, which has cavities, the position of which corresponds to the position of the depressions of the Form roller is adapted, the thermoplastic flows into both Cavities of the dissolvable material as well as in the depressions of the form roller. With such an arrangement, the carrier and the stems are in the Gap formed between the rollers. The beam thickness results from the gap between the pressure and the forming roller, which cannot be released from the belt Material is filled out. It is therefore arbitrary and depending on the application of the adhesive fastener part to be manufactured in this way. By this way of production post-processing by another pair of rollers is not necessary. There the strip of dissolvable material is fed in the form of an endless belt is a continuous and therefore time and cost effective Manufacturing process possible.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens ist das auflösbare Material ein wasserlösliches Material, vorzugsweise Gelatine. Außerdem kann das Band an seinen seitlichen Begrenzugen in Längsrichtung eine Perforation aufweisen, in die entsprechende Vorsprünge der Formwalze eingreifen. Hierdurch wird das Anpassen der Positionen der Hohlräume des Bandes an die Lage der Vertiefungen der Formwalze erleichtert.In a preferred embodiment of the method according to the invention the dissolvable material is a water-soluble material, preferably gelatin. In addition, the belt can be adjusted longitudinally at its lateral boundaries have a perforation in the corresponding projections of the forming roll intervention. This will adjust the positions of the cavities of the Band relieved to the location of the recesses of the forming roller.

Die Höhe der Stengel des fertigen Haftverschlußteiles kann je nach Einsatzzweck variabel eingestellt werden, indem die Dicke des auflösbaren Materials variiert wird. Diese einfache Handhabung ist dadurch möglich, daß die Dicke des auflösbaren Materials gerade der Höhe der Stengel des fertigen Haftverschlußteiles entspricht.The height of the stem of the finished fastener part can vary depending on the application can be adjusted variably by the thickness of the dissolvable material is varied. This simple handling is possible because the Thickness of the dissolvable material just the height of the stem of the finished Adhesive part corresponds.

Die Stengel des so hergestellten Haftverschlußteiles werden in einfacher Weise durch Auflösen des Materials, aus dem das Band besteht, freigelegt. Um das Material aufzulösen, wird das mittels der beiden Walzen hergestellte Haftverschlußteil in einer bevorzugten Ausführungsform der Erfindung im Anschluß an die Walzen durch ein Wasserbad geführt. Das Auflösen des Materials kann durch Ultraschallbehandlung und/oder Erwärmung des Wasserbades beschleunigt werden. Es ist nur ein nachgeschalteter Arbeitsgang für das Entfernen des auflösbaren Materials erforderlich. Ein solcher zusätzlicher Arbeitsgang kann sehr viel einfacher eingerichtet werden als der zusätzliche Walzvorgang, der im Stand der Technik bekannt ist, da hier keine Justierung eines Walzenpaares erforderlich wird.The stems of the adhesive fastener part thus produced are simple by dissolving the material that makes up the tape. To do that To dissolve material, the adhesive closure part produced by means of the two rollers in a preferred embodiment of the invention following the rollers are passed through a water bath. The dissolving of the material can accelerated by ultrasound treatment and / or heating of the water bath will. It is just a downstream step for removing the dissolvable material required. Such an additional operation can can be set up much easier than the additional rolling process, which in the The state of the art is known since there is no adjustment of a pair of rollers is required.

Das erfindungsgemäße Verfahren kann grundsätzlich mit jedem thermoplastischen Kunststoff ausgeführt werden, wobei je nach Verwendungszweck vorzugsweise Polypropylen, Polyamid, Polyethylen, Polyester, PVC und/oder schwerentflammbarerer Kunststoff verwendet werden. Auch Co-bzw. Terpolymere, die einen oder mehrere der genannten thermoplasti schen Kunststoffe enthalten, sind gut geeignet.In principle, the method according to the invention can be used with any thermoplastic Plastic are carried out, preferably depending on the intended use Polypropylene, polyamide, polyethylene, polyester, PVC and / or flame retardant plastic can be used. Also Co or. Terpolymers, one or more of the above-mentioned thermoplastics are well suited.

Die Ausbildung der Verdickungen an den Stengeln kann unterschiedlich sein. Sie können die Form von Pilzköpfen oder die Form von Drei- bis Sechsecken aufweisen. Zusätzlich können die Ecken der drei- bis sechseckigen Verdickungen abgerundet sein, was die Verhakungswahrscheinlichkeit vergrößert.The thickening of the stems can vary. They can be the shape of mushroom heads or the shape of triangles to hexagons exhibit. In addition, the corners of the triangular to hexagonal thickening be rounded, which increases the likelihood of snagging.

Der Träger kann eine Dicke von 0,1 bis 5 mm aufweisen und der Stengeldurchmesser kann 0,1 bis 3 mm betragen. Die Stengelhöhe kann 0,2 mm oder eine beliebige größere Höhe aufweisen.The carrier can have a thickness of 0.1 to 5 mm and the stem diameter can be 0.1 to 3 mm. The stem height can be 0.2 mm or have any greater height.

Wenn dann das Band 7 aus Gelatine der Formwalze 1 zugeführt wird, ist jeder Hohlraum 9 des Bandes 7 über einer Vertiefung 3 der Formwalze positioniert. Zur Vereinfachung dieser Positionierung weist das Band 7 aus Gelatine zusätzlich in Längsrichtung eine Perforation 11 auf, die mit entsprechenden Vorsprüngen 13 der Formwalze 1 zusammenwirkt und so die Positionierung und den Transport des Bandes 7 erleichtert.The belt 7 shown in FIG. 2 made of gelatin becomes the molding roll 1 in shape fed into an endless belt and has open cavities along its entire length 9, which are positioned so that they the position of the recesses 3 of the Forming roller 1 are assigned. Then if the belt 7 made of gelatin the form roller 1 is supplied, each cavity 9 of the band 7 is over a recess 3 of the form roller positioned. To simplify this positioning the band 7 made of gelatin additionally has a perforation 11 in the longitudinal direction on, which cooperates with corresponding projections 13 of the forming roll 1 and so the positioning and transport of the belt 7 facilitated.

Die Dicke a des Bandes 7 ist variabel ab in etwa 0,2 mm bis zu einer beliebigen Dicke einstellbar. Diese Dicke a bestimmt die jeweilige Höhe der Stengel der zu bildenden Verhakungsmittel 5. Der Durchmesser der Hohlräume 9 beträgt in etwa 0,1 bis 3 mm. Aber auch hier kann die Dicke der Hohlräume 9 anders eingestellt werden.The thickness a of the band 7 is variable from about 0.2 mm to any one Adjustable thickness. This thickness a determines the respective height of the stem of the hooking means to be formed 5. The diameter of the cavities 9 is approximately 0.1 to 3 mm. But here too the thickness of the cavities 9 be set differently.

Im Ausführungsbeispiel beträgt diese Dicke in etwa 0,1 - 3 mm. Die Druckwalze 15 und die Formwalze 1 werden in entgegengesetztem Drehsinn angetrieben, und dem genannten Spalt 17 wird mittels eines insgesamt mit 23 bezeichneten Extruders ein thermoplastischer Kunststoff in plastischem oder flüssigem Zustand zugeführt. Dabei fließt der thermoplastische Kunststoff in den Spalt 17 und von dort in die Hohlräume 9 des Bandes 7 und die Vertiefungen 3 der Formwalze 1.In cooperation with the forming roller 1, a pressure roller 15 is arranged the gap 17 between the pressure roller 15 and that on the forming roller 1 located band 7 of gelatin the thickness of the carrier 19 of the finished Adhesive fastener part 21 determines. In the exemplary embodiment, this is Thickness about 0.1 - 3 mm. The pressure roller 15 and the forming roller 1 are in opposite direction of rotation, and the said gap 17 is a thermoplastic by means of an extruder generally designated 23 Plastic supplied in a plastic or liquid state.
