Abstract

In a sleeve-shaped winding core for thin, web-shaped winding material, in order to simplify the fixing of one end of the winding material to the winding core, an adhesive layer (12) of a permanent adhesive is first applied to the winding core, which is formed from numerous paper or cardboard webs. A strip-shaped top web (13) of, for example, paper or cardboard is then wound helically onto this adhesive layer (12), the longitudinal edges (14) of this top web (13) being kept at a specific distance apart. As a result, a helical strip (15) of adhesive layer remains free on the outside, is arranged in a recessed manner relative to the top web (13), and serves to fix the end of the winding material to the winding core (9).

Description

Die Erfindung bezieht sich auf einen hülsenförmigen Wickelkern iür dünnes bahnförmiges Wickelgut, z.B. Papier, Metallfolien, Kunststoffolien, Textilien oder dergleichen, bestehend aus zahlreichen miteinander verbundenen Papier- oder Pappebahnen und einer sich über seine Außenumfangsfläche erstreckenden Klebeschicht zur Fixierung des einen Endes des Wickelgutes am Wickelkern.The invention relates to a sleeve-shaped winding core for thin web-shaped winding material, e.g. Paper, metal foils, plastic foils, textiles or the like, consisting of numerous interconnected paper or cardboard webs and an adhesive layer extending over its outer peripheral surface for fixing the one end of the winding material to the winding core.

Es ist bekannt, zur Befestigung des einen Endes des Wickelguts am Wickelkern ein doppelseitig wirkendes Klebeband auf die Hülsenoberfläche parallel zur Hülsenachse aufzubringen, dessen Außenseite zunächst durch einen Schutzstreifen abgedeckt ist. Beim Verarbeiten der hülsenförmigen Wickelkerne muß dieser Schutzstreifen vorher von Hand entfernt werden, was einen zusätzlichen Arbeitsschritt bedeutet. Außerdem können die Wickelkerne dadurch nicht in vollautomatischen Anlagen verarbeitet werden, in welchen ein ununterbrochener Wechsel der hülsenförmigen Wickelkerne stattfindet.It is known to apply a double-sided adhesive tape to the core surface parallel to the core axis for fixing the one end of the winding material to the core, the outside of which is initially covered by a protective strip. When processing the sleeve-shaped winding cores, this protective strip must first be removed by hand, which means an additional step. In addition, the winding cores cannot be processed in fully automatic systems, in which there is an uninterrupted change of the sleeve-shaped winding cores.

Es ist ferner bekannt, für obige Zwecke mittels Pinsel oder durch Aufsprühen eine Klebeschicht auf die Oberfläche des hülsenförmigen Wickelkerns aufzubringen, und zwar ohne Verwendung eines Abdeckstreifens. Dieses Verfahren läßt sich jedoch nur unmittelbar beim Anwender der Wickelkerne durchführen und die Wickelkerne müssen auch sofort verarbeitet werden.It is also known for the above purposes to apply an adhesive layer to the surface of the sleeve-shaped winding core by means of a brush or by spraying, without using a cover strip. However, this method can only be carried out directly by the user of the winding cores and the winding cores must also be processed immediately.

Schließlich ist es auch bekannt, zur Befestigung des einen Endes des Wickelguts am Wickelkern auf die Oberfläche des hülsenförmigen Wickelkerns eine sog. Heißkleberbahn aufzubringen. Auch diese Methode ist umständlich, denn der Kleber muß dann beim Anwender, vor Verarbeitung des Wickelkerns, erst mittels einer Heizvorrichtung wieder aktiviert werden.Finally, it is also known to apply a so-called hot-melt adhesive strip to the surface of the sleeve-shaped winding core in order to attach one end of the winding material to the winding core. This method is also cumbersome, because the adhesive must then be reactivated by the user before using the winding core by means of a heating device.

Der Erfindung liegt die Aufgabe zugrunde, die obigen Mängel beim Stand der Technik zu vermeiden und die Klebeschicht zur Befestigung des einen Endes des Wickelguts am Wickelkern so auszubilden und anzuordnen, daß die hülsenförmigen Wickelkerne in vollautomatischen Anlagen hergestellt und auch verarbeitet werden können, d.h. daß zur Aktivierung der Klebeschicht keine zusätzlichen Arbeitsschritte erforderlich sein sollen.The invention has for its object to avoid the above shortcomings in the prior art and to form and arrange the adhesive layer for attaching one end of the winding material to the winding core so that the sleeve-shaped winding cores can be produced and also processed in fully automatic systems, ie Activation of the adhesive layer should not require any additional work steps.

Gemäß der Erfindung wird obige Aufgabe dadurch gelöst, daß ein aus einem Dauerkleber gebildeter Klebeschicht-Streifen seitlich durch eine auf der Klebeschicht wendelförmig aufgewickelten Deckbahn aus z.B. Papier oder Pappe begrenzt ist, wobei der Abstand zwischen den Längsrändern der Deckbahn die Breite des wendelförmigen Klebeschicht-­Streifens bestimmt. Ein hülsenförmiger Wickelkern mit diesen Merkmalen kann vorteilhaft in vollautomatischen Anlagen hergestellt und auch verarbeitet werden. Da der wendelförmig verlaufende Klebeschicht-Streifen nicht bündig mit der Außenumfangsfläche der Deckbahn verläuft, sondern etwas tiefer sitzt als diese, wird vorteilhaft beim Versand der hülsenförmigen Wickelkerne ein Zusammenkleben derselben vermieden. Beim Anwender dieser Wickelkerne braucht man nicht, wie bisher, erst einen zusätzlichen Schutzstreifen zu entfernen, sondern das Ende des Wickelguts kann sofort am Wickelkern befestigt werden. Beim Verarbeitungsvorgang bleibt das Wickelgut automatisch an dem aus einem Dauerkleber bestehenden Klebeschicht-­Streifen haften, denn aufgrund der wendelförmigen Anordnung des Klebeschicht-Streifens entfällt das Suchen eines "Anfangs" der Klebeschicht. Da der Abstand zwischen den Längsrändern der Deckbahn variiert werden kann, können auch die Breite des wendelförmigen Klebeschicht-Streifens und damit die jeweils benötigte Haltekraft der Klebeschicht entsprechend beeinflußt werden.According to the invention, the above object is achieved in that an adhesive layer strip formed from a permanent adhesive is laterally wound through a cover sheet of e.g. Paper or cardboard is limited, the distance between the longitudinal edges of the cover sheet determining the width of the helical adhesive layer strip. A sleeve-shaped winding core with these features can advantageously be manufactured and also processed in fully automatic systems. Since the helically extending adhesive layer strip does not run flush with the outer circumferential surface of the cover sheet, but rather sits somewhat lower than this, sticking together of the sleeve-shaped winding cores is advantageously avoided when shipping. When using these winding cores, there is no need to remove an additional protective strip, as before, but the end of the winding material can be attached to the winding core immediately. During the processing operation, the material to be wound automatically adheres to the adhesive layer strip consisting of a permanent adhesive, because the helical arrangement of the adhesive layer strip means that there is no need to find a "start" for the adhesive layer. Since the distance between the longitudinal edges of the cover sheet can be varied, the width of the helical adhesive layer strip and thus the required holding force of the adhesive layer can also be influenced accordingly.

Nach einer Ausgestaltung der Erfindung besteht der Dauerkleber aus einem LatexkleberAccording to one embodiment of the invention, the permanent adhesive consists of a latex adhesive

Nach noch einer weiteren Ausgestaltung der Erfindung beträgt die Dicke der Deckbahn vorzugsweise um ca. 0,1 mm.According to yet another embodiment of the invention, the thickness of the cover sheet is preferably around 0.1 mm.

Die Erfindung wird anschließend anhand der Zeichnung eines Ausführungsbeispiels erläutert. Die Zeichnung zeigt einen Längsschnitt durch einen Teil eines hülsenförmigen Wickelkerns gemäß der Erfindung; wobei die einzelnen Lagen zur besseren Veranschaulichung übertrieben dick gezeichnet sind.The invention is subsequently explained on the basis of the drawing of an exemplary embodiment. The drawing shows a longitudinal section through part of a sleeve-shaped winding core according to the invention; the individual layers are drawn excessively thick for better illustration.

Der Hauptkörper 10 des hülsenförmigen Wickelkerns 9 besteht aus wendelförmig gewickelt en Papier- oder Pappebahnen, die in einer Vielzahl von miteinander verklebten Lagen vorgesehen sind. Auf die äußerste Lage 11 dieses Hauptkörpers 10 ist eine Klebeschicht 12 aus einem sog. Dauerkleber, z.B. einem Latexkleber aufgebracht. Auf diese Klebeschicht 12 ist eine streifenförmige Deckbahn 13 aus z.B. Papier oder Pappe wendelförmig so aufgewickelt, daß ihre Längsränder 14 voneinander beabstandet sind. Die Deckbahn 13 läßt daher einen Klebeschicht-Streifen 15 aus dem Dauerkleber nach außen frei, d.h., die Längsränder 14 der Deckbahn 13 begrenzen seitlich diesen Klebeschicht-­Streifen 15. Der Abstand zwischen den Längsrändern 14 der Deckbahn 13 bestimmt somit die Breite des Klebeschicht-­Streifens 15, an dem das Ende eines dünnen bahnförmigen Wickelguts 16 befestigt wird.The main body 10 of the sleeve-shaped winding core 9 consists of helically wound paper or cardboard webs, which are provided in a plurality of layers bonded together. On the outermost layer 11 of this main body 10 there is an adhesive layer 12 made of a so-called permanent adhesive, e.g. applied a latex glue. On this adhesive layer 12 is a strip-shaped cover sheet 13 made of e.g. Paper or cardboard is wound helically so that its longitudinal edges 14 are spaced apart. The cover sheet 13 therefore leaves an adhesive layer strip 15 exposed to the outside from the permanent adhesive, ie the longitudinal edges 14 of the cover sheet 13 laterally delimit this adhesive layer strip 15. The distance between the longitudinal edges 14 of the cover sheet 13 thus determines the width of the adhesive layer strip 15, to which the end of a thin web-shaped winding material 16 is attached.

Die Deckbahn 13 kann aus Papier oder Pappe bestehen. Die Dicke der Deckbahn 13 beträgt vorzugsweise um ca. 0,1 mm.The cover sheet 13 can be made of paper or cardboard. The thickness of the cover sheet 13 is preferably around 0.1 mm.
