Description

Die Erfindung betrifft ein Band aus einem bei Wärmezufuhr schrumpfba­ ren vernetzten Kunststoff, welches nach Art einer Manschette um einen langgestreckten Gegenstand herumlegbar und nach dem Verbinden der Bandkanten durch Wärmezufuhr auf den Gegenstand schrumpfbar ist.The invention relates to a tape from a heat-shrinkable heat Ren networked plastic, which in the manner of a cuff around one elongated object foldable and after connecting the Band edges can be shrunk by applying heat to the object.

Für die nachträgliche Isolierung und Abdeckung von Verbindungsstellen von elektrischen Kabeln oder Leitungen werden seit langem Schrumpf­ schläuche verwendet, die über die Verbindungsstelle geschoben und dann auf die Verbindungsstelle aufgeschrumpft werden. Für die nachträgliche Abdeckung bzw. Isolierung von Verbindungsstellen bereits verbundener elektrischer Kabel haben sich Manschetten aus wärmeschrumpfbarem Kunststoff durchgesetzt, die als Band um die Verbindungsstelle herumgelegt, an ihren Längskanten mechanisch fest verbunden und anschließend auf die Verbindungsstelle aufgeschrumpft werden.For the subsequent insulation and covering of connection points of electrical cables or wires have been shrinking for a long time used hoses that are pushed over the connection point and then be shrunk onto the joint. For the subsequent covering or insulation of connection points already connected electrical cables have cuffs heat shrinkable plastic enforced, which as a band around the Connection point laid around, mechanically fixed on its longitudinal edges connected and then shrunk onto the connection point  will.

Die Verbindung der Längskanten erfolgt beispielsweise durch Klemmschienen, aber auch durch Verkleben der einander überlappenden Bandkanten (DE-AS 15 25 815).The longitudinal edges are connected, for example, by Clamping rails, but also by gluing the overlapping one another Band edges (DE-AS 15 25 815).

Der Längsschlitz einer solchen Muffe wird zur zusätzlichen Abdichtung häufig noch mit einer mit der Manschette verklebbaren Lasche oder Zunge unterlegt.The longitudinal slot of such a sleeve becomes an additional seal often with a tab that can be glued to the cuff or Tongue underlaid.

Zur Herstellung eines Abzweiges in einer solchen Muffe wird das Band, aus dem die Manschette gebildet ist, vor dem Schrumpfen zwischen den abzweigenden Leitungen mittels einer Klammer zusammengehalten.To produce a branch in such a sleeve, the tape, from which the cuff is formed, before shrinking between the branching lines held together by a bracket.

Nachteilig bei diesen bekannten Konstruktionen ist, daß durch die Verschlußschienen und die für den Eingriff der Verschlußschiene erforderlichen Randverdickungen der Manschette eine vielfach störende verdickte Längsnaht entsteht. Ein weiterer Nachteil ist darin zu sehen, daß große Längen von Kabeln oder Rohren oder Leitungen mit solchen Manschetten nicht einstückig bzw. kontinuierlich umhüllt werden können.A disadvantage of these known constructions is that Lock rails and for the engagement of the lock rail required thickening of the edge of the cuff a frequently disruptive thickened longitudinal seam is formed. Another disadvantage is there too see that great lengths of cables or pipes or lines with such cuffs not encased in one piece or continuously can be.

Der vorliegenden Erfindung liegt von daher die Aufgabe zugrunde, ein Band anzugeben, welches ohne zusätzliche Verschlußelemente, wie z. B. Verschlußschienen, um Kabel, Rohre oder Leitungen herumgelegt und verschlossen werden kann und welches darüber hinaus geeignet ist, Kabel, Rohre oder Leitungen größerer Länge kontinuierlich zu ummanteln.The present invention is therefore based on the object Specify tape, which without additional closure elements such. B. Locking rails, laid around cables, pipes or lines and can be closed and which is also suitable Cables, pipes or lines of greater length continuously encase.

Diese Aufgabe wird dadurch gelöst, daß die zu verbindenden Band­ kantenbereiche aus nicht vernetztem Kunststoff bestehen und die Verbindung der Bandkanten durch Schmelzschweißen erfolgt. Durch die Erfindung wird die vor dem Schrumpfen erforderliche feste Verbindung der Bandkanten durch Schweißen erreicht. Neben der hohen mechanischen Festigkeit der Schweißnaht entsteht darüber hinaus noch der Vorteil, daß die Schweißnaht gegenüber einer durch Verschlußschienen zusam­ mengehaltenen oder verklebten Naht wesentlich dichter gegen Eindrin­ gen von Feuchtigkeit ist. Die Ausbildung der Bandkantenbereiche aus nicht vernetztem Kunststoff ist aus dem Grunde erforderlich, da sich vernetzte Kunststoffe nicht verschweißen lassen. Damit genügend Material für die Schweißnaht zur Verfügung steht, hat es sich als zweckmäßig erwiesen, die Bandkantenbereiche gegenüber der Wanddicke des Bandes verdickt auszubilden. Diese verdickten Randbereiche haben darüber hinaus noch den Vorteil, daß sie für den Reckvorgang herangezogen werden können. Als Material für das Band kann nahezu jeder beliebige vernetzbare Kunststoff verwendet werden. Es hat sich jedoch als vorteilhaft erwiesen, das Band aus einem vernetzten Polyäthylen herzustellen, dem Silangruppen aufgepfropft sind, wobei die Bandkantenbereiche aus nicht vernetztem Polyäthylen bestehen. Ein mit Silangruppen gepfropftes Polyäthylen läßt sich ohne großen maschinellen Aufwand leicht vernetzen. Ist es beispielsweise erforderlich, daß auch der Bereich der Schweißnaht vernetzt ist, so kann man dies dadurch erreichen, daß die Bandkantenbereiche aus einem peroxydisch vernetzbaren Polyäthylen bestehen. Der Schweißnahtbereich wird dann nach dem Verschweißen durch zusätzliche Erwärmung, durch welche das Vernetzungsmittel, d. h. in diesem Fall die Peroxyde, aktiviert werden, vernetzt. Zumindest eine der Oberflächen des Bandes ist, wie an sich bekannt, mit einem Dicht-Korrosionsschutz und/oder Klebemittel beschichtet. Das Band ist zweckmäßigerweise einstückig extrudiert.This object is achieved in that the band to be connected edge areas are made of non-cross-linked plastic and the The band edges are connected by fusion welding. Through the Invention becomes the firm connection required before shrinking the strip edges are reached by welding. In addition to the high mechanical Strength of the weld seam also has the advantage that the weld seam compared to one through closure rails quantity-held or glued seam is much denser against penetration moisture. The formation of the band edge areas Non-cross-linked plastic is necessary because of the reason Do not let cross-linked plastics weld. That is enough  Material for which the weld seam is available, it has proven to be Proven to be the band edge areas compared to the wall thickness of the tape thickened. These have thickened edge areas furthermore the advantage that they are for the stretching process can be used. The material for the tape can be almost any cross-linkable plastic can be used. It has However, it has been shown to be advantageous to crosslink the tape To produce polyethylene, the silane groups are grafted, wherein the band edge areas consist of non-cross-linked polyethylene. A Polyethylene grafted with silane groups can be easily network machine effort easily. For example it is required that the area of the weld seam is also networked, so this can be achieved in that the band edge areas from one peroxide crosslinkable polyethylene. The weld area is then after welding by additional heating, by which the crosslinking agent, d. H. in this case the peroxides, be activated, networked. At least one of the surfaces of the tape is, as is known per se, with a sealing corrosion protection and / or Adhesive coated. The band is expediently in one piece extruded.

Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines Bandes wie oben beschrieben, welches sich dadurch auszeichnet, daß ein Band aus vernetzbarem Kunststoff mittels eines Extruders und eines als Breitschlitzdüse ausgebildeten Formwerkzeuges extrudiert wird, daß innerhalb des Formwerkzeuges an die Längskanten des Bandes je ein Streifen aus einem vom Kunststoffmaterial des Bandes unter­ schiedlichen Kunststoff angeformt wird, daß der Kunststoff des Bandes vernetzt wird, wobei die durch die Streifen gebildeten Randbereiche des Bandes unvernetzt bleiben, daß nach dem Vernetzen das Band auf eine Temperatur oberhalb des Kristallitschmelzpunktes erwärmt, quer zur Längsrichtung des Bandes gereckt und abschließend im gereckten Zustand abgekühlt wird. Mit Hilfe des erfindungsgemäßen Verfahrens ist es gelungen, Bänder, die quer zu ihrer Längsrichtung schrumpfbar sind, in nahezu unendlicher Länge herzustellen. Die Vernetzung wird zweckmäßigerweise bei Gegenwart von Feuchtigkeit vorgenommen, wozu es erforderlich ist, daß ein mit Silanen gepfropftes Polyäthylen verwendet wird. Die Randbereiche des Bandes werden gegenüber der Wanddicke des Bandes verdickt extrudiert und dienen als Kraft­ angriffsbereich beim kontinuierlichen Reckvorgang bzw. als Zusatz­ schweißmaterial. Dabei ist es erforderlich, daß durch die Reck­ vorrichtung die Randbereiche gekühlt werden, um die erforderliche Reckkraft auf das Band aufbringen zu können. Das Verfahren zur Herstellung des Bandes beschränkt sich nicht auf feuchtigkeits­ vernetzbare Kunststoffe, sondern ist in gleicher Weise einsetzbar für Kunststoffe, die mittels energiereicher Strahlung vernetzt werden. Hierbei werden während der Vernetzung die Kantenbereiche des Bandes abgedeckt und somit nicht vernetzt.The invention further relates to a method for producing a Volume as described above, which is characterized in that a belt made of crosslinkable plastic by means of an extruder and a molding tool designed as a slot die extruded will that within the mold to the long edges of the belt one strip each from one of the plastic material of the band under different plastic is molded that the plastic of the tape is cross-linked, the edge regions formed by the strips of the tape remain unconnected, that after connecting the tape on a temperature warmed above the crystallite melting point, across stretched to the longitudinal direction of the tape and finally in the stretched Condition is cooled. With the help of the method according to the invention succeeded in making tapes that shrink transversely to their longitudinal direction are to be produced in almost infinite lengths. The networking will expediently made in the presence of moisture, for what it it is necessary that a polyethylene grafted with silanes is used. The edge areas of the tape are opposite the  Wall thickness of the tape extrudes thickened and serve as a force area of attack during continuous stretching or as an additive welding material. It is necessary that through the horizontal bar device the peripheral areas are cooled to the required To be able to apply stretching force to the belt. The procedure for Production of the tape is not limited to moisture crosslinkable plastics, but can be used in the same way for Plastics that are cross-linked using high-energy radiation. Here, the edge areas of the tape become during crosslinking covered and therefore not networked.

Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung einer Umhüllung für langgestrecktes Gut unter Verwendung eines Bandes nach einem oder mehreren der vorgenannten Ansprüche. Das Band wird dabei nach Art einer Manschette um den Gegenstand herumgelegt, an seinen Randbereichen verschweißt und anschließend geschrumpft. Dabei erfolgt die Verschweißung zweckmäßigerweise durch Spiegelschweißen. Beim Spiegelschweißen werden die zu verschweißenden Bandkantenbereiche mittels eines beheizten Werkzeuges, beispielsweise einer Zunge oder eines Spiegels, auf Schmelztemperatur gebracht und gegeneinander gepreßt, bis die Schmelzzone erstarrt ist. Um eine über den gesamten Umfang durchgehend vernetzte Manschette bzw. Umhüllung zu erreichen, werden die Randbereiche während oder nach der Verschweißung vernetzt. Hierbei ist es zweckmäßig, wie bereits erwähnt, die Randbereiche aus einem peroxydisch vernetzbaren Kunststoff zu extrudieren.The invention further relates to a method for producing a Wrapping for elongated goods using a tape behind one or more of the preceding claims. The tape will be there wrapped around the object like a cuff, on his Edge areas welded and then shrunk. This is done the welding expediently by mirror welding. At the The strip edge areas to be welded are mirror-welded by means of a heated tool, for example a tongue or of a mirror, brought to melting temperature and against each other pressed until the melting zone has solidified. To one over the entire To reach the extent of the continuously connected cuff or covering, the edge areas are cross-linked during or after welding. As already mentioned, it is expedient here for the edge regions to extrude a peroxidically crosslinkable plastic.

Die Erfindung betrifft weiterhin ein Verfahren zur kontinuierlichen Umhüllung von durchlaufendem langgestreckten Gut. Hierbei wird das von einer Vorratsspule ablaufende Band kontinuierlich um das durchlaufende langgestreckte Gut zu einem Schlitzrohr geformt, an seinen Längskanten verschweißt und nach dem Schweißen zum Schrumpfen gebracht. Mit besonderem Vorteil läßt sich das genannte Verfahren zum Umhüllen von gewellten Metallrohren verwenden, wobei die Schrumpfung so durchgeführt wird, daß das Bandmaterial nahezu dem Wellenverlauf des Metallrohres folgt. Für das ummantelte Metallrohr entsteht dadurch der Vorteil, daß die eigentliche Flexibilität des metalli­ schen Wellrohres durch den zusätzlichen Kunststoffmantel nicht wesentlich eingeschränkt wird. Bei ummantelten Wellrohren, die nach der herkömmlichen Technik hergestellt wurden, bei denen ein glatter Kunststoffmantel auf die Wellenberge des Wellrohres aufextrudiert wurde, war die Flexibilität sehr stark eingeschränkt.The invention further relates to a method for continuous Wrapping of continuous elongated goods. Here is the from a supply reel continuously running around the continuous elongated material formed into a slotted tube its longitudinal edges welded and after welding to shrink brought. The above-mentioned method for Use enveloping corrugated metal pipes, causing the shrinkage is carried out so that the strip material almost the waveform follows the metal pipe. For the covered metal tube is created thereby the advantage that the actual flexibility of the metalli corrugated pipe due to the additional plastic jacket is significantly restricted. With coated corrugated pipes, the  the conventional technology, in which a smoother Plastic jacket extruded onto the corrugations of the corrugated pipe flexibility was very limited.

Um eine saubere Oberfläche der Umhüllung zu erreichen, hat es sich als zweckmäßig erwiesen, nach dem Verschweißen die im Bereich der Schweißnaht gelegene Verdickung zu entfernen und danach die Umhüllung auf das Metallwellrohr aufzuschrumpfen. Weitere Gegenstände der Erfindung sind verschiedene Muffen unter Verwendung eines erfin­ dungsgemäßen Bandes. Bei einer Abzweigmuffe besteht die Muffe aus zwei Bändern, die an ihren Längskanten miteinander stumpf verschweißt sind. Die Abzweige werden durch nochmalige Verschweißung einer bestimmten Länge der Schweißnähte gebildet. Bei einer T-förmigen Abzweigmuffe ist die Muffe aus einem kreuzförmigen Band hergestellt, welches über den T-förmigen Abzweig gelegt und an den Berührungslini­ en verschweißt ist. Eine Doppel-T-förmige Abzweigmuffe zeichnet sich dadurch aus, daß zwei identische kreuzförmige Bänder übereinander­ gelegt und an den in Längsrichtung des Kabels bzw. der Leitung oder des Rohres verlaufenden Berührungskanten verschweißt sind.In order to achieve a clean surface of the wrapper, it has proven to be useful after welding the in the area of Remove the thickening located at the weld seam and then the covering shrink onto the corrugated metal pipe. Other objects of the Invention are various sleeves using an invented appropriate band. In the case of a branch sleeve, the sleeve consists of two tapes butt-welded together on their long edges are. The branches are welded together again certain length of the weld seams formed. With a T-shaped Branch sleeve, the sleeve is made of a cross-shaped band, which is placed over the T-shaped branch and on the contact line is welded. A double T-shaped branch sleeve stands out characterized in that two identical cruciform tapes one above the other placed and on the in the longitudinal direction of the cable or line or contact edges of the pipe are welded.

Um das kontinuierlich zugeführte Metallwellrohr 10, hierbei kann es sich jedoch auch um ein Glattrohr handeln, wird das von einer Vorratsspule 11 abgezogene Band 1 zu einem Schlitzrohr geformt, im Bereich seiner Bandkanten mittels einer Spiegelschweißeinrichtung 12 verschweißt und in nicht dargestellter Weise der Schweißgrat entfernt. Mittels einer Nach­ wärmvorrichtung 13 wird die Schweißnaht 5 so weit erwärmt, daß die Peroxyde zerfallen und das Kunststoffmaterial der Schweißnaht 5 sowie der angrenzenden Bereiche vernetzt wird. Das so umhüllte Rohr wird dann in einen Durchlaufofen 14 eingeführt, in dem das Kunststoffband auf Schrumpftemperatur gebracht wird, so daß es sich der Wellenform des Wellrohres 10 folgend auf dieses auflegt. Fig. 7 shows a method in a schematic representation, with which a metallic corrugated tube 10 can be continuously wrapped with a plastic band made of cross-linked material. The continuously supplied corrugated metal tube 10 , but this can also be a smooth tube, the strip 1 drawn off from a supply reel 11 is formed into a slotted tube, welded in the region of its strip edges by means of a mirror welding device 12 and the welding burr removed in a manner not shown. By means of a warming device 13 , the weld 5 is heated to such an extent that the peroxides disintegrate and the plastic material of the weld 5 and the adjacent areas are crosslinked. The tube thus encased is then introduced into a continuous furnace 14 , in which the plastic strip is brought to shrinking temperature, so that it follows the waveform of the corrugated tube 10 thereon.

Die Fig. 8 zeigt in der Draufsicht ein vorgerecktes Band 1, welches kreuzförmig durch Spritzgießen hergestellt ist. Die Randbereiche 3 a und 3 b aus unvernetztem Kunststoff sind beim Spritzgießen mit angeformt. Das dargestellte Band ist biaxial, d. h. in zwei senkrecht zueinander stehenden Achsen, die dem Verlauf der Kreuzbalken folgen, gereckt. Ein solches Band kann zur Herstellung einer T-Abzweigverbin­ dung eingesetzt werden, indem das Band um den T-Abzweig herumgelegt und an seinen Bandkanten 3 a und 3 b verschweißt wird. Nach dem Verschweißen wird - wie oben beschrieben - geschrumpft. Die Reckung des Bandes 2 kann auch dadurch erzielt werden, daß die Mittel­ bereiche 2 der das Kreuz bildenden Balken im Querschnitt halbkreis­ förmig gereckt werden (siehe Fig. 8a). Zur Herstellung eines Doppel-T-Abzweiges werden zwei der in den Fig. 8 bzw. 8a dargestell­ ten Bänder 1 über den Doppel-T-Abzweig gelegt, an den Kanten 3 a und 3 b verschweißt und anschließend geschrumpft. Fig. 8 shows in plan view a prestretched belt 1 which is cross-shaped by injection molding. The edge regions 3 a and 3 b made of non-cross-linked plastic are molded on during injection molding. The band shown is stretched biaxially, ie in two mutually perpendicular axes that follow the course of the crossbeams. Such a band can be used to produce a T-branch connection by laying the band around the T-branch and welding it to its band edges 3 a and 3 b . After welding - as described above - shrinking. The stretching of the band 2 can also be achieved in that the central regions 2 of the cross-forming beams are stretched semicircular in cross section (see Fig. 8a). To prepare a double-T-feeder, two of the set shown in Figs. 8 and 8a dargestell ten ribbons 1 through the double-T-branch, at the edges 3 a and 3 b are welded and then shrunk.

Die Fig. 9 zeigt eine Abzweigmuffe, wie sie beispielsweise in der Nachrichtentechnik zur Abzweigung von Kabeln dienen. Um die nicht sichtbare Abzweigstelle wird ein aus zwei Einzelbändern 1 herge­ stelltes Band, welches durch Verschweißen der Längskanten 3 a und 3 b hergestellt ist, herumgelegt und an seinen noch nicht verbundenen Längskanten 3 a und 3 b (in der Fig. 9 obenliegend) verschweißt. Im Bereich des Abzweigs werden die beim Verbinden der Bänder bzw. des Bandes erzeugten Schweißnähte miteinander verschweißt, wie bei 15 dargestellt und anschließend die Abzweigmuffe geschrumpft. Wie bei allen auf der Baustelle herzustellenden Schweißnähten wird auch die Schweißnaht 15 durch Spiegelschweißen mit einem elektrisch oder gasbeheizten Spiegel hergestellt. Fig. 9 shows a branch sleeve, as they are used for example in telecommunications to branch cables. To the invisible branching point is a Herge of two single belts 1 notified band which is a fabricated by welding the longitudinal edges 3 and 3 b, wrapped and at its not yet associated longitudinal edges 3 a and 3 b (in Fig. 9 on top) welded . In the region of the branch, the weld seams produced when the strips or the strip are connected are welded to one another, as shown at 15 , and the branch sleeve is then shrunk. As with all weld seams to be produced on the construction site, the weld seam 15 is also produced by mirror welding with an electrically or gas-heated mirror.
