Abstract

A reusable yarn carrier for threads consists in its essential part of a cylindrical basic body (1) made of hard paper, wood or plastic having a flush exchangeable covering (3) which possesses, over the end face on the yarn run-off side, a circular groove (5), the inner wall (5'') of which projects beyond the outer wall (5'). The plastic covering (3) is crimped over the outer edge (4) of the end face and is fastened to the inner groove wall (5''). In an alternative version, the basic body (1) is equipped with a head part (2). The head part (2) serves for receiving a linear-density disc and makes handling easier. <IMAGE>

Description

Die Erfindung betrifft einen Garnträger zur mehrfachen Verwendung für Fäden, bestehend aus einem im wesentlichen zylindrischen Grundkörper mit einer Wandstärke von wenigstens 4 mm, frei von inneren Einbauten, aus einem Hartpapier, einem Holz oder einem Kunststoff, mit einem auswechselbaren Ueberzug.The invention relates to a yarn carrier for multiple use for threads, consisting of an essentially cylindrical base body with a wall thickness of at least 4 mm, free of internal fittings, made of hard paper, wood or plastic, with a replaceable cover.

Garnträger sind Massenprodukte und bestehen meistens aus spiralgewickeltem Karton oder Kunststoff. Sie haben sich als Einweghülsen für hohe Aufwickelgeschwindigkeiten bewährt (Chemiefasern/Textil-Industrie, Juni 1976, Seiten 522-525).Yarn carriers are mass products and mostly consist of spiral-wound cardboard or plastic. They have proven themselves as disposable cores for high winding speeds (man-made fibers / textile industry, June 1976, pages 522-525).

Mehrfach verwendbare Garnträger, sogenannte Kopshülsen, weisen Innenaufbauten auf, sind nicht vollkommen wuchtfrei herzustellen und daher für höhere Geschwindigkeiten ungeeignet.Reusable thread carriers, so-called head tubes, have internal structures, are not completely balanced, and are therefore unsuitable for higher speeds.

Aus der GB-A-993228 ist eine Einweghüse bekannt, die aus Papier gefertigt und mit einem an ihrem äusseren Rand eigebördelten Kunststoffüberzug versehen ist. Allerdings sind solche Hülsen zur Stapelung aufeinander und Wiederverwendung völlig ungeeignet. Eine Mehrfachverwendung hat sich bei Hülsen dieser Art als unwirtschaftlich erwiesen, da die bekannten Hülsen vor allem an ihren Stirnseiten und Oberflächen beschädigt oder deformiert werden. Garnträgerhülsen müssen eine bestimmte Stabilität aufweisen, damit sie nicht von dem auf sie aufzuspulenden Garn verformt oder zusammengedrückt werden. Eine solche Hülse ist nicht wiederverwendbar. Das Aussortieren erfolgt meistens von Hand und kann nicht nur auf optisch sichtbare Mängel beschränkt werden; es müssen auch versteckte Mängel erfasst werden, um bei einer wiederverwendbaren Hülse, Rundlaufprobleme und Ablaufbehinderungen des Garnes zu vermeiden. Die bekannten Garnhülsen müssen eine definierte, möglichst homogene Oberfläche aufweisen und sind daher relativ aufwendig in ihrer Herstellung und Kontrolle.From GB-A-993228 a disposable sleeve is known, which is made of paper and is provided with a plastic coating flanged on its outer edge. However, such sleeves are completely unsuitable for stacking on top of one another and for reuse. Multiple use with sleeves of this type has proven to be uneconomical, since the known sleeves are damaged or deformed, especially on their end faces and surfaces. Yarn carrier sleeves must have a certain stability so that they are not deformed or compressed by the yarn to be wound on them. Such a sleeve is not reusable. Sorting is usually done by hand and cannot be limited to visible defects only; hidden defects must also be recorded in order to avoid run-out problems and flow problems of the yarn in the case of a reusable sleeve. The known yarn tubes have to have a defined surface which is as homogeneous as possible and are therefore relatively complex to manufacture and control.

Ein grosses Problem stellt neuerdings die Entsorgung der Einweghülsen dar. Die Forderung nach einer Hülse aus abbaubarem Kunststoff ist aus wirtschaftlichen Gründen noch nicht erfüllbar. Es wird versucht, Sammelstellen für das Recycling der leeren Hülsen einzurichten, aber eine Lösung für die Aufarbeitung der in grossen Mengen anfallenden Hülsen besteht noch nicht.The disposal of disposable sleeves has recently become a major problem. For economic reasons, the demand for a sleeve made of degradable plastic cannot yet be met. Attempts are being made to set up collection points for recycling the empty tubes, but there is still no solution for processing the tubes in large quantities.

Aufgabe der Erfindung ist es, einen Garnträger zur Verfügung zu stellen, welcher mehrfach einsetzbar ist und die Nachteile der bekannten Garnträger nicht aufweist.The object of the invention is to provide a yarn carrier which can be used multiple times and does not have the disadvantages of the known yarn carriers.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die garnablaufseitige Stirnseite aus einer äusseren Wand und einer inneren Wand besteht, wobei der Ueberzug bündig über die äussere Kante der äusseren Wand des Grundkörpers gebördelt ist und beide Stirnseiten des Garnträgers einen gleichen Innendurchmesser aufweisen.This object is achieved according to the invention in that the end of the yarn outlet on the yarn outlet side consists of an outer wall and an inner wall, the cover being flanged flush over the outer edge of the outer wall of the base body and both end faces of the yarn carrier having the same inner diameter.

Ein wesentlicher Vorteil des gleichen Innendurchmessers ist es, dass ein oder mehrere der erfindungsgemässen Garnträger rasch und unmittelbar auf den Dorn einer Spulmaschine aufgeschoben werden können.A major advantage of the same inner diameter is that one or more of the yarn carriers according to the invention can be quickly and directly pushed onto the mandrel of a winding machine.

Der Grundkörper besteht bevorzugt aus Hartpapier oder Holz, dessen Oberfläche nicht kritisch ist, dass heisst, nicht definiert zu sein braucht. Solche Hülsen können daher ohne grossen Aufwand wirtschaftlich hergestellt werden. Der Grundkörper kann aber auch aus jedem Kunststoff bestehen, welcher sich allerdings im Gebrauch nicht verformen darf, damit seine Wiederverwendbarkeit gewährleistet ist. Die Wandstärke der Hülse sollte wenigstens 4 mm, bevorzugt 6 mm betragen, was ein mehrfaches der Dicke eines Ueberzuges darstellt. Sie ist jedoch weitgehend von den Stabilitätsanforderungen an den Grundkörper abhängig, was wiederum vom aufzuwickelnden Garn bestimmt wird.The base body preferably consists of hard paper or wood, the surface of which is not critical, that is to say does not need to be defined. Such sleeves can therefore be manufactured economically with little effort. The base body can also consist of any plastic, which, however, must not deform during use, so that its reusability is guaranteed. The wall thickness of the sleeve should be at least 4 mm, preferably 6 mm, which is a multiple of the thickness of a coating. However, it is largely dependent on the stability requirements for the base body, which in turn is determined by the yarn to be wound up.

Zweckmässig ist im Grundkörper eine kreisförmige Rinne vorgesehen. Sie dient zur versenkbaren Aufnahme eines Kunststoffüberzuges. Damit entsteht im Innern der Garnträgerhülse ein Hohlraum ohne Einbauten. Dies erlaubt, auf einen Dorn, je nach seiner Länge, mehreren hintereinander angeordnete Garnträgern aufzustecken. Die äussere Kante der Rinne ist vorteilhafterweise niedriger als die innere und gewährleistet einen einwandfreien Ablauf eines Garnes. Ausserdem ist die vorstehende innere Kante ein Schutz bei der Stapelung und dem Transport einer vollen Spule. Das Spulengewicht lastet auf dieser Kante.A circular channel is expediently provided in the base body. It is used to retract a plastic cover. This creates a cavity in the interior of the yarn carrier sleeve without any internals. Depending on its length, this allows a number of yarn carriers arranged one behind the other to be attached to a mandrel. The outer edge of the trough is advantageously lower than the inner one and ensures that a yarn runs smoothly. In addition, the protruding inner edge is a protection when stacking and transporting a full spool. The coil weight rests on this edge.

Die äussere Fläche des Grundkörpers ist bündig mit einem auswechselbaren Kunststoffüberzug versehen, der über die äussere Kante der garnablaufseitigen Stirnfläche gebördelt ist. Auswechselbar bedeutet, dass der Kunststoffüberzug bei einer Beschädigung leicht ausgetauscht werden kann, was durch Aufschneiden und Abziehen des alten Ueberzuges und Aufziehen eines neuen erfolgt. Das Austauschen erfolgt zweckmässigerweise automatisch. Der Ueberzug kann aus jedem Kunststoff oder Papier bestehen, auf dem das aufgewickelte Garn keine Rillenspuren hinterlässt und der gegen Schlag weitgehend unempfindlich ist. Seine Oberfläche kann entsprechend dem zu verarbeitenden Garn entweder glatt oder rauh oder beispielsweise orangenhautartig gestaltet sein. Eine glatte Oberfläche, insbesondere über der Stirnseitenkante, erlaubt einen beschädigungslosen Abzug des Garnes, beispielsweise in der Weberei, beim Texturieren und bei der Kettherstellung. Der Einzug und die Befestigung in der um 360 Grad verlaufenden Rinne gewährleistet eine sichere vollständige Verankerung des Kunststoffüberzugs.The outer surface of the base body is flush with an exchangeable plastic cover which is flanged over the outer edge of the end surface on the yarn outlet side. Interchangeable means that the plastic cover can be easily replaced if damaged, which is done by cutting and peeling off the old cover and fitting a new one. The replacement is conveniently done automatically. The cover can be made of any plastic or paper on which the wound yarn leaves no groove marks and which is largely insensitive to impact. Its surface can be either smooth or rough or, for example, orange peel-like in accordance with the yarn to be processed. A smooth surface, especially over the front edge, allows the yarn to be pulled off without damage, for example in weaving, texturing and warp-making. The retraction and fastening in the 360-degree channel ensures that the plastic cover is securely anchored completely.

Der Grundkörper kann aber auch mit einem Kopfteil versehen sein, der einen Auflagering trägt. In diesem Fall ist die Rinne mit der äusseren niedrigeren und inneren höheren Wand im Kopfteil vorgesehen. Der mit dem Kopfteil verbundene Auflagering hat den Vorteil, dass darauf Garnbezeichnungen angebracht werden können, die sonst an einer unzweckmässigen Stelle angebracht werden müssen. Ein Anbringen der Bezeichnung direkt auf einem Kunststoffüberzug ist gerade für einen Mehrweggebrauch unzweckmässig. Ein weiterer Vorteil ist darin zu sehen, dass mittels des Ringes auf einfache Weise eine volle Spule vom Dorn abgezogen und beschädigunglos transportiert werden kann.The base body can also be provided with a head part which carries a support ring. In this case, the gutter with the outer lower and inner higher wall is provided in the head part. The support ring connected to the head part has the advantage that yarn names can be attached to it, which would otherwise have to be attached at an inappropriate point. Attaching the designation directly to a plastic cover is particularly inappropriate for reusable use. Another advantage is the fact that the ring can be used to easily pull a full spool off the mandrel and transport it without damage.
