Parallel zum Anfang 6 der ersten Lage 2 der Papierbahn ist ein streifenförmiges Verbindungsklebemittel 7 für das Verbinden des Anfanges 6 der neuen Vorratspapierbahnrolle 1 mit der zu Ende gehenden Papierbahnrolle angeordnet. Dieses Verbindungsklebemittel 7 kann aus einem bekannten Leimauftrag oder aus einem bekannten doppelseitig klebendem Klebestreifen bestehen. Das Verbindungsklebemittel 7 kann mit einer seiner Seitenlinien deckungsgleich zum Anfang 6 der ersten Lage 2 der Papierbahn verlaufen oder in einem gleichmäßigen Abstand a zum Anfang 6 der ersten Lage 2 der Papierbahn angeordnet sein (Fig. 4). Der Anfang 6 der ersten Lage 2 der Papierbahn ist mittels, einer Anzahl von aus Heißschmelzkleber 15 bestehenden Tropfen 16 auf der zweiten Lage 9 der Papierbahn befestigt. Mehrere dieser Tropfen 16 sind in Papierlaufrichtung gesehen hintereinander fadenförmig aufgebracht, so daß sich eine Fadenform 8 (Fig. 2) ausbildet, welche teilweise, vorzugsweise zur Hälfte, sowohl auf dem Anfang 6 der ersten Lage 2 der Papierbahn als auch teilweise auf der zweiten Lage 9 der Papierbahn angeordnet ist. Längsachsen 11 durch die Fäden 8 verlaufen dabei parallel zu seitlichen Rändern der Papierbahnrolle 1. Die Fäden 8 sind über die gesamte Breite der Papierbahnrolle 1 in einem Abstand b zueinander angeordnet. Der Abstand b kann entsprechend der Grammatur des zu verarbeitenden Papiers frei gewählt werden. Eine Länge l der Fäden 8 kann bis zu einer Breite des streifenförmigen Verbindungsklebemittels 7 betragen. Der zu verwendende Heißschmelzkleber 15 sollte zu 100 Prozent aus festen Bestandteilen bestehen, kein Wasser sowie keine flüchtigen oder brennbaren Lösungen enthalten, nach dem Auftragen bei Raumtemperatur schnell erstarren, somit schnell Anziehen und eine minimale Schrumpfung aufweisen.One symbolized by the top layers Supply paper web roll 1 as a new supply roll for Connect to the paper web of an almost expired one Paper web roll has at its outermost, i.e. H. first Layer 2 a parallel to an axis of rotation of the Paper web roll 1 beginning 6.

A distance b the drop 16 with one another can be the same as in the first Design example to be dimensioned. This also happens Applying the drops 16 and connecting two Paper webs as in the first embodiment spelled out. After connecting both paper webs the beginning 6 of the first layer 2 is torn the paper web in the form of a semicircle-like Aufrißstelle 17 to the second layer 9 of the Paper web remaining, a diameter d having circular drops 16 Hot melt adhesive 15.

Die Tropfen 16 aus Heißschmelzkleber 15 können auch eine dreieckige, sternförmige, ovale oder jede andere beliebige geometrische Form aufweisen.The drops 16 from hot melt adhesive 15 can also be a triangular, star-shaped, oval or any other have any geometric shape.

Der Anfang 6 der Papierbahn kann auch schräg statt parallel zur Rotationsachse der Vorratspapierbahnrolle 1 verlaufen, oder auch V-, W- oder Doppel-W-förmig.The beginning 6 of the paper web can also take place at an angle parallel to the axis of rotation of the stock roll 1 run, or also V, W or double W-shaped.

Bei einem weiteren Ausführungsbeispiel ist vorgesehen, mehrere Tropfen 22 aus schnell erstarrendem Material, z. B. Heißschmelzkleber 15 auf der zweiten Lage 9 der Vorratspapierbahnrolle 1 in Vorratspapierbahnrollen-Längsachsenrichtung gesehen, voneinander beabstandet so anzuordnen, daß ein Teil der Peripherie der Tropfen 22 ebenfalls mit dem Anfang 6 der Papierbahn stoffschlüssig verbunden ist. Dabei kann im Bereich des Anfanges 6 der Papierbahn ein streifenförmiges Verbindungsklebemittel 7 aufgebracht sein (Fig. 5).In a further exemplary embodiment, several drops 22 of rapidly solidifying material, e.g. B. hot melt adhesive 15 on the second layer 9 of the Stock roll of paper 1 in Stock paper web roll longitudinal axis direction seen, spaced from each other so that part of the Periphery of the drops 22 also with the beginning 6 of the Paper web is integrally connected. It can in Area of the beginning 6 of the paper web strip-shaped connecting adhesive 7 applied be (Fig. 5).

Statt Heißschmelzkleber als schnell erstarrendes Material, welches nach dem Abbinden nicht mehr klebt, kann auch ein Reaktionsklebstoff, d. h. ein Klebstoff, der durch chemische Reaktion abbindet, verwendet werden. Dieses Abbinden oder Verfestigen erfolgt entweder physikalisch, z. B. durch Abkühlen, d. h. Verdunsten von Lösungs- oder Dispersionsmitteln, oder chemisch. Beides oder eine Kombination von Beiden führt zu maximaler Festigkeit.Instead of hot melt glue as a rapidly solidifying Material that no longer sticks after setting, can also be a reactive adhesive, i.e. H. an adhesive, which sets by chemical reaction can be used. This setting or hardening takes place either physically, e.g. B. by cooling, d. H. Evaporate from Solvents or dispersants, or chemically. Both or a combination of both leads to maximum Strength.

Es ist auch möglich, einen durch Zurechtschneiden neu gebildeten Anfang einer Vorratspapierbahnrolle elektrostatisch so aufzuladen, daß dieser auf der zweiten Lage der Vorratspapierbahnrolle zumindest solange festgehalten wird, bis die vorgenannten Tropfen bzw. Fäden den Anfang der Vorratspapierbahnrolle auf der zweiten Lage der Vorratspapierbahnrolle stoffschlüssig festgelegt haben. It is also possible to recreate one by trimming it formed beginning of a stock paper roll charge electrostatically so that this on the second layer of the stock paper roll at least is held until the aforementioned drops or threads the beginning of the supply paper web roll on the second layer of the supply paper web roll cohesively have determined.
