Description

Die Erfindung betrifft Aufwickelrohre oder Aufwickelhülsen für biegsame, lagenweise aufzuwickelnde Materialien, z.B. Stoffbahnen.The invention relates to take-up tubes or take-up sleeves for flexible, layer-wise wound materials, e.g. Fabric panels.

Bei herkömmlichen Aufwickelrohren ist die Position des Beginns der aufzuwickelnden Materialbahn relativ zum Aufwickelrohr in der Regel nicht fest vorgegeben und demzufolge der Anfang der Bahn nicht eindeutig fixiert. Beim Aufwickeln der Materialbahn ergibt sich eine Unstetigkeitsstelle bzw. eine Stoßstelle, insbesondere beim Aufwickeln von dickeren Materialbahnen aufgrund der Überlappung zwischen der ersten und der zweiten sowie weiteren Wickellagen. Weiterhin können sich in Achsrichtung des Aufwickelrohres Verziehungen der Materialbahn bei der anfänglichen Auflage der Bahn ergeben, so dass der Aufwickelvorgang leicht schräg erfolgen kann.In conventional wind-up tubes, the position of the beginning of the material web to be wound up is generally not fixed relative to the take-up tube, and consequently the beginning of the web is not clearly fixed. When winding the material web results in a discontinuity or a joint, especially when winding thicker material webs due to the overlap between the first and the second and further winding layers. Furthermore, in the axial direction of the take-up tube, distortions of the material web may result in the initial application of the web, so that the winding-up process can be carried out slightly obliquely.

Aufgabe der Erfindung ist, die vorbeschriebenen Nachteile auszuschalten und die bei Aufwickelrohren bekannter Art auftretenden Überlappungen der ersten Wickellagen und Verziehungen der Materialbahn beim Aufwickeln zu vermeiden.The object of the invention is to eliminate the disadvantages described above and to avoid the overlaps occurring during Aufwickelrohren known type of the first winding layers and distortions of the web during winding.

Gemäß der Erfindung wird dies dadurch erreicht, dass in der äußeren Umfangsfläche des Aufwickelrohres bzw. der Aufwickelhülse in axialer Richtung eine rinnenförmige, nutenförmige, muldenförmige oder dergl. Vertiefung vorgesehen ist, in die der Anfangsrand der Materialbahn eingelegt und darin festgelegt wird. Diese Festlegung erfolgt vorzugsweise durch eine Klebeverbindung zwischen Aufwickelrohr und Materialbahn.According to the invention this is achieved in that in the outer peripheral surface of the take-up tube or the take-up in the axial direction, a trough-shaped, groove-shaped, trough-shaped or the like. Well is provided, in which the initial edge of the web is inserted and fixed therein. This determination is preferably carried out by an adhesive bond between the winding tube and material web.

Die Vertiefung ist zweckmäßigerweise so ausgebildet, dass sie einen in Aufwickelrichtung etwa keilförmig verlaufenden Querschnitt hat, so dass die eine Begrenzungsfläche der Nut oder Rinne in etwa radialer Richtung verläuft, während die andere Begrenzungsfläche der Nut einen nahezu tangentialen Verlauf zur Umfangsfläche besitzt. Alternativ kann die Rinne bzw. Nut auch konvexe oder konkave Form haben, wobei der Übergang dieser Form in die Umfangsfläche des Rohres zumindest in Aufwickelrichtung für einen glatten Übergang gerundet ist.The recess is expediently designed so that it has a wedge-shaped in the winding approximately cross-section, so that the one boundary surface of the groove or groove extends in an approximately radial direction, while the other boundary surface of the groove has a nearly tangential course to the peripheral surface. Alternatively, the groove may also have a convex or concave shape, wherein the transition of this shape in the peripheral surface of the tube is rounded at least in the winding direction for a smooth transition.

Die Vertiefung im Aufwickelrohr und/oder die Randbegrenzung des Anfangsteiles der Materialbahn weisen wahlweise eine durchgehende oder stellenweise unterbrochene oder punktförmige Haftverbindung auf, so dass damit die Materialbahn am Anfang der Bahn eindeutig und nicht verschiebbar mit dem Aufwickelrohr verbunden ist und die Gefahr eines Verziehens der Materialbahn beim Aufwickeln entfällt.The recess in the winding tube and / or the boundary of the initial part of the web optionally have a continuous or locally interrupted or punctiform adhesive bond, so that thus the web at the beginning of the web is clearly and not slidably connected to the take-up tube and the risk of warping the web when winding is eliminated.

Das Aufwickelrohr oder die Aufwickelhülse für eine Materialbahn ist in Fig. 1 in perspektivischer Ansicht mit 1 bezeichnet und weist eine rinnen- oder nutförmige Vertiefung 2 auf, die von einem Ende des Aufwickelrohres achsparallel bis zum anderen Ende des Aufwickelrohres mit gleichem Querschnitt verläuft. Die Nut bzw. Rinne 2 stellt eine Aussparung geringer Tiefe dar, die V-förmig oder keilförmig im Querschnitt ausgebildet ist und einen etwa radial verlaufenden Schenkel 3 sowie einen etwa tangential verlaufenden Schenkel 4 besitzt, wobei der etwa tangential verlaufende Schenkel 4 weitgehend kontinuierlich in die Umfangsfläche übergeht. Das Aufwickelrohr oder die Aufwickelhülse ist ein zylindrischer Aufnahmeträger für die Materialbahn, der aus Karton oder Kunststoff besteht und der aus Gewichts- und Stabilitätsgründen rohrförmig ausgeführt ist. Die Tiefe dieser Aussparung beträgt einen Bruchteil der Rohr- oder Hülsendicke, so dass durch diese Aussparung die mechanische Stabilität des Aufwickelrohres oder der Aufwickelhülse 1 nicht beeinträchtigt wird. Mit 6 ist eine Materialbahn dargestellt, die sich über die volle Breite des Aufwickelrohres 1 erstreckt und deren Anfangs-Querrand 8 einen in axialer Richtung durchgehenden oder unterbrochenen Streifen 7 besitzt, der mit dem nahezu tangentialen Schenkel 4 der rinnenförmigen oder nutenförmigen Vertiefung 2 eine Haftverbindung eingeht, wobei wahlweise die Fläche 4 des Rohres oder die Fläche 7 der Materialbahn 6 oder beide einen Kleber aufweisen, der die Haftverbindung zwischen beiden herstellt.The winding tube or the winding sleeve for a material web is in Fig. 1 designated in perspective view with 1 and has a trough-shaped or groove-shaped recess 2 which extends from one end of the take-up tube axially parallel to the other end of the take-up tube with the same cross-section. The groove or channel 2 is a recess of shallow depth, which is V-shaped or wedge-shaped in cross section and has an approximately radially extending leg 3 and an approximately tangentially extending legs 4, wherein the approximately tangentially extending leg 4 is substantially continuous in the Peripheral surface passes. The take-up tube or the take-up tube is a cylindrical receiving carrier for the material web, which consists of cardboard or plastic and which is made tubular for weight and stability reasons. The depth of this recess is a fraction of the tube or sleeve thickness, so that the mechanical stability of the take-up tube or the take-up sleeve 1 is not affected by this recess. 6 shows a material web which extends over the full width of the Aufwickelrohres 1 extends and whose initial transverse edge 8 has a continuous or interrupted in the axial direction strip 7, which forms an adhesive bond with the almost tangential leg 4 of the channel-shaped or groove-shaped recess 2, optionally the surface 4 of the tube or the surface 7 of the web 6 or both have an adhesive which establishes the adhesive bond between the two.

In Fig. 2 ist die Vertiefung in Form eines Querschnittes längs der Schnittlinie I - I im Ausschnitt dargestellt. Die Linie 3 bezeichnet den einen Schenkel der Verbindung, der etwa radial im Rohr oder in der Hülse ausgebildet ist, während die Linie 4 eine etwa gerade Linie darstellt, die angenähert tangential zur Umfangslinie des Rohres bzw. der Hülse ausgebildet ist, so dass der Anfang 7 bzw.8 der Materialbahn 6 in die Vertiefung 3, 4 eingelegt werden und an der Stelle 5 weitgehend kontinuierlich in die Umfangsfläche des Rohres bzw. der Hülse 1 übergehen kann. Die Dimension des Schenkels 3 entspricht dabei in etwa der Dicke der Materialbahn 6, so dass in eingelegtem Zustand der Materialbahn in die Vertiefung ein kontinuierlicher Verlauf der Umfangsfläche bei eingelegter Materialbahn 6 mit möglichst geringer Unstetigkeit am Übergang 5 vorgesehen ist. Der Streifen 7 der Materialbahn ist mit der Fläche 4 durch eine Klebeverbindung festgelegt, wobei die Klebeschicht 9 auf der Unterseite des Streifens 7 oder auf der Oberseite der Vertiefung 4 oder auf beiden ausgebracht sein kann, und die jeweilige Klebefläche vorher z.B. durch eine Schutzfolie abgedeckt ist.In Fig. 2 the recess in the form of a cross section along the section line I - I is shown in the cutout. The line 3 denotes the one leg of the connection, which is formed approximately radially in the tube or in the sleeve, while the line 4 represents an approximately straight line, which is formed approximately tangential to the circumferential line of the tube or the sleeve, so that the beginning 7 and 8 of the material web 6 are inserted into the recess 3, 4 and at the point 5 can pass substantially continuously into the peripheral surface of the tube or the sleeve 1. The dimension of the leg 3 corresponds approximately to the thickness of the material web 6, so that in the inserted state of the material web in the recess a continuous course of the peripheral surface is provided with inserted material web 6 with the least possible discontinuity at the transition 5. The strip 7 of the material web is fixed to the surface 4 by an adhesive bond, wherein the adhesive layer 9 may be applied to the underside of the strip 7 or on the top of the recess 4 or both, and the respective adhesive surface is previously covered for example by a protective film ,

Bei der Ausführungsform nach Fig. 3 ist die den Übergang zu der Umfangsfläche des Rohres 1 darstellende Fläche 4 im Querschnitt leicht gebogen ausgeführt, so dass an der Stelle 5 ein nahtloser und weitgehend frei von Unstetigkeit ausgebildeter Übergang erzielt wird.In the embodiment according to Fig. 3 is the transition to the peripheral surface of the tube 1 performing surface 4 is slightly bent in cross-section, so that at the point 5 a seamless and largely free of discontinuity trained transition is achieved.

Die Figuren 4 und 5 zeigen weitere Ausgestaltungen der Erfindung. In Fig. 4 ist die Vertiefung in der äußeren Rohr-Umfangsfläche muldenförmig ausgebildet, wobei die Tiefe der Mulde entsprechend dem Anfangs-Querstreifen 7 der Materialbahn angepasst ist und der Beginn der Materialbahn einen verstärkenden Querstreifen 8 hat, so dass die Mulde durch einen z.B. verstärkten Querstreifen 7 bewirkt, dass ein nahtloser und stetiger Übergang erzielt wird, wenn die zweite Materialbahnlage 6' und weitere Materialbahnlagen aufgewickelt werden.The FIGS. 4 and 5 show further embodiments of the invention. In Fig. 4 the recess in the outer tube peripheral surface is trough-shaped, wherein the depth of the trough is adapted according to the initial transverse strip 7 of the material web and the beginning of the material web has a reinforcing transverse strip 8, so that the trough by an example reinforced transverse strip 7 causes that a seamless and steady transition is achieved when the second material web layer 6 'and further material web layers are wound up.

In Fig. 6 ist eine Muldenform der Vertiefung dargestellt, wobei die beiden Seitenwände der Vertiefung symmetrisch und angenähert tangential zur Umfangsfläche verlaufend ausgebildet sind und die Materialbahn die Mulde weitgehend ausfüllt.In Fig. 6 a trough shape of the recess is shown, wherein the two side walls of the recess are formed symmetrically and approximately tangent to the peripheral surface and the material web largely fills the trough.
