Description

Vorrichtung zum Abwickeln einer Stoffbahn von ihrer Speicher-Rolle Die Erfindung betrifft eine Vorrichtung zum Abwickeln einer Stoffbahn von ihrer Speicher-Rolle.Device for unwinding a web of material from its storage roll The invention relates to a device for unwinding a web of material from it Memory role.

Die Erfindung dient also zum Abwickeln von Material, insbesondere dünnen und weichen Papiers von Lagerrollen (einzelnen oder mehreren), zwecks Zusammenbringens oder Schichtens in vielfache Lagen, Leimen, Falten, Längs- und Querforieren, Loch stanzen, Längs- und Querschneiden und ähnlicher Vorgänge. Ein fehler- und störungsfreies Arbeiten wird dabei durch eine Kombination oder Einzel aggregate folgender Art erfindungsgemäß erreicht: Rei der Vorrichtung sind über die ganze Bahnbreite wirksame angetriebene Abzugsrollen vorgesehen und in Abzugsrichtung der Bahn weitere angetriebene Rollen, die die Bahn nur über einen schmalen Randbereich erfassen. Zwecks einwandfreien Arbeitens bediente man sich zumeist aufwendiger Kanten-Regelungsvorrichtungen. The invention thus serves to unwind material, in particular thin and soft paper from storage rolls (single or multiple) for the purpose of bringing them together or layering in multiple layers, gluing, folding, longitudinal and transverse perforation, hole punching, longitudinal and cross cutting and similar processes. An error-free and trouble-free Work is carried out according to the invention by a combination or individual units of the following type Achieved: Rei of the devices are effectively driven over the entire width of the web Take-off rollers provided and further driven rollers in the take-off direction of the web, which cover the web only over a narrow edge area. In order to be flawless For the most part, complex edge control devices were used.

Die Erfindung besteht nun darin, daß die vorgeordneten Zug- und Abmeßrollenpaare nur auf einer Seite der Bahn vorgesehen sind. The invention consists in the fact that the upstream tension and metering roller pairs are only provided on one side of the track.

Dadurch findet ein besonders guter Geradlauf der Bahn statt, selbst dann noch, wenn das Papier über die Bahnbreite verschiedene Zugspannung aufweist. This results in a particularly good straight run of the track itself then even if the paper has different tensile stress across the width of the web.

Als Vorteil ergibt sich, daß die Regelvorrichtung überflüssig wird und daß das Einfädeln der Bahn leichter ist. Tangential- und Peripherierollen, die meist je Paar nur auf eine Materialbahn einwirken, sind nur einzeln (nicht in unter gegenseitigem Druck stehenden Paaren) angeordnet, und ihre Einwirkung auf das gezogene Material entsteht lediglich durch Oberflächenkontakt und Reibung. The advantage is that the control device is superfluous and that threading the web is easier. Tangential and peripheral rollers that usually only act on one sheet of material per pair, are only available individually (not in under mutual pressure standing pairs), and their action on the drawn Material is created only through surface contact and friction.

Es ist dabei zu bemerken, daß ihre Antriebswirkung proportional zur Papierspannung ist, d. h. vom Zug der Zugrollen und der erforderlichen Abzugskraft von den Lagerrollen beeinflußt wird. It should be noted that their driving effect is proportional to Paper tension is d. H. from the pull of the pulling rollers and the required pull-off force is influenced by the bearing rollers.

Vorteil a) Wenn große Abzugskraft erforderlich ist (schwere Materialrollen), erhöht sich der Tangential- und Peripherie-Rollenzug automatisch, kann aber nie einen eigenen Vortrieb und damit Spannungsverlust erwirken. b) Faltenbildung, die durch Quertriebs-Antriebsrollen, die über die ganze Breite des Materials beiderseitig einwirken, wird vermieden. c) Die fliegende, einseitige Lagerung der Zug- und Abmeßrollen ist übersichtlicher und ermöglicht leichteres Einfädeln des Materials. Advantage a) If a large pull-off force is required (heavy material rolls), the tangential and peripheral roller tension increases automatically, but never can achieve their own propulsion and thus loss of tension. b) wrinkling, the by means of transverse drive rollers that cover the entire width of the material on both sides act is avoided. c) The flying, one-sided mounting of the tension and measuring rollers is clearer and enables easier threading of the material.

Die Material-Abwickel-Vorrichtung bietet folgende Vorteile: d) einseitig unterstützte Aufhängung bzw. Montage der Materialrollen, e) Verstellbarkeit der Rollenposition in axialer Richtung während des Betriebs oder Abwickelns, f) Erleichterung des Abwickelns im Moment des Anlaufens durch Nachgeben. The material unwinding device offers the following advantages: d) one-sided supported suspension or assembly of the material rolls, e) adjustability of the Roll position in the axial direction during operation or unwinding, f) relief of unwinding at the moment of starting by giving way.

In der Zeichnung ist ein Ausführungsbeispiel der Abwickelvorrichtung im Aufriß in Fig.1 schematisch dargestellt, und F i g. 2 zeigt eine Draufsicht. In the drawing is an embodiment of the unwinding device shown schematically in elevation in FIG. 1, and FIG. 2 shows a plan view.

Mit 1 ist die auf einer Achse 2 lagernde Speicher-Rolle bezeichnet. Das abzuspulende Materialband ist 3. Vor der Rolle 1 sind übereinander achsparallel, möglicherweise versetzt zueinander, sogenannte Tangential- und Peripherie-Abzugsrollen 4 und 5 angeordnet, über die das Materialband läuft und deren Umfangsgeschwindigkeit gleich oder größer ist als die der noch weiter vorn in Abzugsrichtung einseitig angeordneten Zug- und Abmeßrollenpaare 6 und 7, welche das Materialband an einem nur schmalen Rand erfassen. 1 with the storage roller mounted on an axis 2 is designated. The material strip to be unwound is 3. In front of the roll 1 are axially parallel on top of each other, possibly offset to one another, so-called tangential and peripheral take-off rollers 4 and 5 arranged, over which the material strip runs and their peripheral speed is equal to or greater than that of the one-sided further forward in the withdrawal direction arranged tension and metering roller pairs 6 and 7, which the strip of material on a capture only the narrow edge.
