Abstract

The process for winding a paper or cardboard web (12) comprises feeding it over a carrier roller and forming a nip between this and a drum. When the drum is full, the web is cut by cutters (26) which begin cutting near the edges of the web and move towards the middle where the cuts meet. The web is then transferred to a new, empty drum. An Independent claim is included for a winding machine for carrying out the process.

Description

Die Erfindung betrifft ein Verfahren zum Aufwickeln einer Materialbahn wie insbesondere einer Papier- oder Kartonbahn, bei dem die Materialbahn über eine Tragtrommel geführt und zwischen der Tragtrommel und dem Tambour ein Wickelspalt gebildet wird und die Materialbahn für einen jeweiligen Tambourwechsel durchtrennt wird. Sie betrifft ferner eine Wickelmaschine gemäß dem Oberbegriff des Anspruchs 15.The invention relates to a method for winding a material web such as in particular a paper or cardboard web in which the material web guided over a carrier drum and between the carrier drum and a winding gap is formed for the drum and the material web for one each drum change is severed. It also concerns one Winding machine according to the preamble of claim 15.

Eine entsprechende Wickelmaschine wird beispielsweise am Ende einer der Herstellung oder Veredelung einer Materialbahn dienenden Maschine eingesetzt. Sie kann beispielsweise auch dazu dienen, eine bereits fertig gewickelte Wickelrolle umzuwickeln. Bei der betreffenden Maschine kann es sich beispielsweise um eine Papier-, Karton- oder Tissuemaschine handeln.A corresponding winding machine is, for example, at the end of a the production or refinement of a machine that serves as a material web used. For example, it can also be used to finish one to wind the wound winding roll. With the machine in question it is, for example, a paper, cardboard or tissue machine.

Zum Trennen der Materialbahn für einen jeweiligen Tambourwechsel sind verschiedene Einrichtungen bekannt. So werden neben Gooseneck und Randkobra heute zunehmend auch mit Hochdruck betriebene Wasserstrahldüsen eingesetzt. Ein Nachteil von Gooseneck und Randkobra besteht darin, daß die Materialbahn nicht sauber auf den neuen, noch leeren Tambour aufgeführt werden kann. Zudem gewährleistet das Trennen mit Luft keinen sauberen Schnitt, was insbesondere bei stark längs orientierten Papieren dazu führen kann, daß die Bahn nicht über die gesamte Breite reißt, sondern nach dem Trennen eines Teils der Bahn nur noch ein Längsriß auftritt. Der Gooseneck weist überdies den Nachteil auf, daß er eine aufwendige Mimik benötigt, um die Blasdüse in die Bahnmitte zwischen dem vollen und dem neuen, noch leeren Tambour einschwenken zu können.To separate the material web for a respective reel change various facilities known. So in addition to Gooseneck and Edge cobra today increasingly also with high-pressure water jet nozzles used. There is a disadvantage of Gooseneck and Randkobra in that the material web is not clean on the new, nor empty Drum can be performed. The separation also ensures not a clean cut with air, which is particularly the case with strongly longitudinal ones Papers can result in the web not covering the entire Width tears, but only after part of the web separates Longitudinal crack occurs. The Gooseneck also has the disadvantage that it elaborate facial expressions are required to place the blow nozzle in the middle of the web swing in the full and the new, still empty drum can.

Ziel der Erfindung ist es, ein Verfahren sowie eine Wickelmaschine der eingangs genannten Art zu schaffen, mit denen bei minimalem baulichem Aufwand ein möglichst sicherer Trennvorgang gewährleistet ist.The aim of the invention is to provide a method and a winding machine to create the type mentioned, with which with minimal structural The safest possible separation process is guaranteed.

Hinsichtlich des Verfahrens wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Materialbahn mittels zweier allgemein quer zur Bahnlaufrichtung verfahrbarer Trennelemente geschnitten wird, indem die beiden Trennelemente im Bereich der beiden Bahnränder zur Bildung eines Streifens im Abstand vom jeweiligen Bahnrand angesetzt und anschließend bei laufender Materialbahn zumindest bis zur Bahnmitte verfahren werden.With regard to the method, this object is achieved according to the invention solved that the material web by means of two generally transverse to the web running direction movable dividers is cut by the two Separating elements in the area of the two web edges to form a Strips at a distance from the respective web edge and then with the material web running, at least move to the center of the web become.

Entsprechend ist die erfindungsgemäße Wickelmaschine dadurch gekennzeichnet, daß zwei allgemein quer zur Bahnlaufrichtung verfahrbare Trennelemente vorgesehen sind, die zum Schneiden der Materialbahn im Bereich der beiden Bahnränder zur Bildung eines Streifens im Abstand vom jeweiligen Bahnrand ansetzbar und anschließend bei laufender Materialbahn zumindest bis zur Bahnmitte verfahrbar sind.Accordingly, the winding machine according to the invention is characterized in that that two generally traversable to the web direction Separating elements are provided, which for cutting the material web in Area of the two web edges to form a strip at a distance attachable from the respective web edge and then with the material web running can be moved at least to the middle of the track.

Bei den Trennelementen kann es sich insbesondere um Schneidelemente handeln. The separating elements can in particular be cutting elements act.

Aufgrund dieser Ausbildung ist bei jedem Tambourwechsel stets ein äußerst sicherer und zuverlässiger Trennvorgang gewährleistet, wobei der hierfür erforderliche bauliche Aufwand auf ein Minimum reduziert ist.Because of this training, there is always an extreme with every reel change ensures safe and reliable separation process, the the structural effort required for this is reduced to a minimum.

In bestimmten Fällen ist es zweckmäßig, wenn die Materialbahn mittels der Trennelemente in Bahnlaufrichtung vor der Tragtrommel geschnitten wird.In certain cases, it is useful if the material web by means of cut the dividing elements in the direction of web travel in front of the carrier drum becomes.

Bei einer zweckmäßigen alternativen Ausführungsform wird die Materialbahn mittels der Trennelemente auf der Tragtrommel geschnitten.In an expedient alternative embodiment, the material web cut on the carrier drum by means of the separating elements.

Insbesondere in dem Fall, daß die Materialbahn mittels der Trennelemente vor der Tragtrommel oder auf dieser geschnitten wird, ist es von Vorteil, wenn die Materialbahn vorzugsweise so geschnitten, daß sich die durch die beiden Trennelemente erzeugten Schnittlinien im Bereich der Bahnmitte überschneiden.Especially in the case that the material web by means of the separating elements before or on the carrier drum, it is advantageous if the material web is preferably cut so that the through the two separating elements produced cutting lines in the area of the center of the web overlap.

Erfolgt der Schneidvorgang bei an der Tragtrommel anliegendem vollem Tambour, so kann ein jeweiliger Streifen in einem zwischen einem neuen, noch leeren Tambour und dem vollen Tambour gelegenen Bereich auf der Tragwalze durchtrennt werden. Dabei kann ein jeweiliger Streifen beispielsweise mittels einer Blasdüse, eines Schabers oder eines Wasserstrahls durchtrennt werden. If the cutting process is carried out with the full on the carrier drum Drum, so a respective strip in a between a new, empty drum and the full drum area on the Carrier roller to be cut. A respective strip can, for example by means of a blowing nozzle, a scraper or a water jet be severed.

Dabei kann ein jeweiliger Streifen mittels einer Blasdüse, eines Wasserstrahls oder eines beweglichen Elements wie insbesondere eines Abschlagmessers durchtrennt werden.However, the cutting process takes place at a distance from the carrying drum arranged full drum, so a respective strip in the exposed area between a new, still empty drum and be cut through the full drum. A respective strip can be used by means of a blowing nozzle, a water jet or a movable one Elements such as a cutting knife in particular.

In bestimmten Fällen ist es zweckmäßig, wenn ein jeweiliger Streifen mittels eines in den Wickelspalt zwischen der Tragtrommel und dem neuen Tambour eingeführten doppelseitig wirkenden Klebeelements, vorzugsweise mittels eines zweiseitigen Klebebands, durchtrennt wird.In certain cases it is advisable to use a respective strip one in the winding nip between the carrier drum and the new one Drum inserted double-sided adhesive element, preferably by means of a double-sided adhesive tape.

Grundsätzlich kann die Materialbahn mittels der zwei Trennelemente auch an dem neuen, noch leeren Tambour geschnitten werden.In principle, the material web can be made by means of the two separating elements can also be cut on the new, still empty drum.

Bei einer weiteren zweckmäßigen Ausführungsform wird die Materialbahn mittels der Trennelemente in Bahnlaufrichtung nach der Tragtrommel geschnitten. Dabei wird die Materialbahn zweckmäßigerweise so geschnitten, daß sich die durch die beiden Trennelemente erzeugten Schnittlinien im Bereich der Bahnmitte überschneiden.In a further expedient embodiment, the material web cut by means of the separating elements in the direction of web travel after the carrier drum. The material web is expediently cut in such a way that the cutting lines generated by the two separating elements overlap in the area of the web center.

Zur Unterstützung des Anwickelns der ersten Lagen an den neuen Tambour kann beispielsweise ein doppelseitiges Klebeband verwendet werden.To support the winding of the first layers on the new drum For example, double-sided adhesive tape can be used.
