Description

Die vorliegende Erfindung bezieht sich auf einen Wickeldorn zur Herstellung von einseitig offenen zylindrischen und Rollreifen aufweisenden Behältern aus mit Kunstharz versehenem Fasermaterial. The present invention relates to a winding mandrel for manufacture from containers with cylindrical and rolling hoops that are open on one side Synthetic resin coated fiber material.

Bei der Herstellung von Behältern mit Rollreifen wird im allgemeinen der zylindrische Mantelkörper zunächst ausgebildet, auf den anschließend ringförmige Verstärkungen in Form von Rollreifen aufgebracht werden. Bei Behältern aus Kunststoff ist es möglich, die Rollreifen auf den zylindrischen Behältermantel nachträglich aufzusetzen und durch Klebung zu verbinden; dies bedingt eine Fertigung von getrennten Teilen und damit eine Werkstoffanhäufung an den Stellen der Rollreifen. In the manufacture of containers with rolling hoops, generally the cylindrical shell body is initially formed, on the subsequently ring-shaped Reinforcements are applied in the form of rolling hoops. For containers made of plastic it is possible to add the rolling hoops to the cylindrical container shell afterwards put on and bonded together; this requires a production of separate Parts and thus an accumulation of material at the points of the rolling tires.

Nach der vorliegenden Erfindung können Behälter mit Hilfe eines Wickeldornes hergestellt werden, wobei Werkstoffanhäufungen wie auch Klebestellen an den Rollreifen vermieden werden. Dies wird dadurch erreicht, daß auf dem Umfang des Wickeldornes mit Verbindungskanälen verbundene Ringnuten vorgesehen sind, in welchen an sich bekannte verlorene auflösbare oder aufblasbare Kerne eingelegt sind. According to the present invention, containers can be made with the aid of a winding mandrel are produced, with material accumulations as well as glue points on the rolling tires be avoided. This is achieved in that on the circumference of the winding mandrel annular grooves connected to connecting channels are provided in which per se known lost dissolvable or inflatable cores are inserted.

Gemäß einem weiteren Merkmal der Erfindung sind über den Ringnuten des Wickeldornes elastische Dichtstreifen oder aufblasbare Membranringe angeordnet. An der Trennstelle für die beiden Behälter ist ein mit einem Anschlußventil versehener Verbindungskanal vorgesehen, der in die die Ringnuten miteinander verbindenden Kanäle mündet. According to a further feature of the invention are over the annular grooves the winding mandrel arranged elastic sealing strips or inflatable membrane rings. At the point of separation between the two containers there is one with a connection valve Connection channel provided in the channels connecting the annular grooves to one another flows out.

Die Erfindung wird im folgenden an Hand der Zeichnungen an einem Ausführungsbeispiel erläutert. The invention is in the following with reference to the drawings on a Embodiment explained.

Es zeigt Fig. 1 einen fertiggewickelten Behälter, Fig. 2 teilweise im Schnitt zwei auf einen Dorn gewickelte Behälter, F i g. 3 und 4 in vergrößerter Schnittdarstellung Einzelheiten einer Ringnut mit eingelegtem aufblasbarem Kern, F i g. 5 einen vergrößerten Teilschnitt an der Trennstelle der beiden Behälter, an der ein Ventil für Druckgas- bzw. Lösungsmittelzuführung zu den Verbindungskanälen angeordnet ist.1 shows a completely wound container, FIG. 2 partially in section two containers wound on a mandrel, FIG. 3 and 4 in enlarged Sectional view of details of an annular groove with an inserted inflatable core, F i g. 5 shows an enlarged partial section at the point of separation of the two containers, on which a valve for the supply of pressurized gas or solvent to the connecting channels is arranged.

Wie in Fig. 2 dargestellt, werden für die gleichzeitige Herstellung zweier einseitig offener Behälter Bodenteile 1 auf die Stirnseiten eines Wickeldornes 2 aufgesetzt. Anschließend werden die Mantelflächen 3 im Wickelverfahren hergestellt. Die Bodenteile 1 sind so gestaltet, daß der Wickeldorn 2 durch sie in der Wickelmaschine gehalten und mitgenommen wird. In der Mantelfläche des Wickeldornes sind für jeden im Behälter vorgesehenen Rollreifen 4 Ringnuten 5 über den Dornumfang vorgesehen. Zur Bildung der Vorsprünge auf dem Wickeldorn für die Sicken in der Mantelfläche des Behälters sind in den Ringnuten 5 z. B. aufblasbare Schläuche 6 oder entsprechend geformte verlorene und auflösbare Kerne eingelegt. Die Ringnuten 5 sind mit Verbindungskanä- len 7 im Wickeldorn 2 verbunden, und an der vorgesehenen Trennstelle 13 zum Auftrennen des Mantelkörpers ist ein in die Verbindungskanäle 7 mündender Verbindungskanal 8 angeordnet, der an ein Ventil 9 angeschlossen wird, über welches die aufblasbaren Kerne 6 unter Druck gesetzt werden können. Die Ausnehmung für das Ventil 9 auf dem Wickeldorn 2 wird von einem Stopfen 10 überdeckt, um eine einwandfreie Oberfläche für den Wickeldorn zu bilden und zu vermeiden, daß Harz beim Wickelverfahren in diese Ausnehmung eindringt. As shown in Fig. 2, are used for simultaneous manufacture two container base parts 1 open on one side on the end faces of a winding mandrel 2 put on. The lateral surfaces 3 are then produced using the winding process. The base parts 1 are designed so that the winding mandrel 2 through them in the winding machine is held and taken away. In the outer surface of the mandrel are for everyone 4 ring grooves 5 provided over the circumference of the mandrel are provided in the container. To form the projections on the mandrel for the beads in the outer surface of the container are in the grooves 5 z. B. inflatable tubes 6 or equivalent Shaped lost and dissolvable cores inserted. The annular grooves 5 are equipped with connecting channels len 7 connected in the winding mandrel 2, and at the intended separation point 13 for separating of the jacket body is a connecting channel opening into the connecting channels 7 8 arranged, which is connected to a valve 9, via which the inflatable Cores 6 can be pressurized. The recess for the valve 9 on the Winding mandrel 2 is covered by a plug 10 in order to have a perfect surface to form for the winding mandrel and to avoid resin in the winding process this recess penetrates.

Die F i g. 3 und 4 erläutern die Funktion des aufblasbaren Kerns 6. In den Ringnuten 5 ist der aufblasbare Kern, z. B. ein Schlauch 6, eingelegt. F i g. 3 stellt die Lage des Schlauches 6 im aufgeblasenen Zustand dar, während Fig. 4 die Lage des Schlauches im entspannten Zustand darstellt. Um zu verhindern, daß beim Wickeln Harz zwischen Nut und Schlauch läuft, sind in der Mantelfläche des Wickeldornes 2 Dichtstreifen 11 vorgesehen, an welche sich der aufblasbare Schlauch 6 unter Druck anlegt und damit den Hohlraum zur Ringnut abdichtet. Die Dichtstreifen können auch als Ringmembran ausgebildet werden, die, unter Druckgas gesetzt, sich hervorwölben und einen Vorsprung bilden, auf den die gewünschten Sicken gewickelt werden können. The F i g. 3 and 4 explain the function of the inflatable core 6. In the annular grooves 5, the inflatable core, for. B. a hose 6 is inserted. F i g. 3 shows the position of the tube 6 in the inflated state, while Fig. 4 shows the position of the hose in the relaxed state. To prevent, that resin runs between the groove and the hose during winding are in the jacket surface of the winding mandrel 2 sealing strips 11 are provided, to which the inflatable tube 6 applies under pressure and thus seals the cavity to the annular groove. The sealing strips can also be designed as an annular membrane, which, when pressurized gas, is bulge out and form a protrusion on which the desired beads are wound can be.

Fig. 5 zeigt das Ventil 9 und den Stopfen 10 in vergrößerter Darstellung. In dieser Darstellung ist angenommen, daß der fertige Behälter an seinem offenen Ende mit Flanschringen 12 und darin eingearbeiteten Dichtnuten versehen sein muß. Diese Flanschringe 12 sind vor dem Beginn des Wickelns an der Trennstelle 13 auf den Wickeldorn 2 aufgebracht worden. Die Ränder werden nach dem Auftrennen längs der Trennebenel3 bis zu dem vorgesehenen Behälterrand 14 abgedreht. Fig. 5 shows the valve 9 and the plug 10 in an enlarged view. In this illustration it is assumed that the finished container is at its open The end must be provided with flange rings 12 and sealing grooves incorporated therein. These flange rings 12 are open at the separation point 13 before winding begins the winding mandrel 2 has been applied. The edges will be lengthways after ripping the parting plane 3 turned down to the intended container edge 14.
