Definitions
- the invention relates to a textile tool having a point or edge or a stitch-forming part.
- Textile tools often have very fine structures, such as in particular tips, edges, hooks, tongues and the like, which must be particularly stable.
- the stability is achieved for example by appropriate wear protection layers that extend over tips, hooks, tongues or cutting the textile tool away.
- wear protection layers such as chrome plating, metal overlays, hard coatings or the like provide a high abrasion resistance.
- these wear protection layers thus lend the textile tool increased robustness, they can unexpectedly increase the sensitivity of the textile tool to atypical loads.
- wear protection layers in particular in the region of large curvatures, such as points, hooks or edges, at untypical loads, such as impact or impact or in contact with other hard objects, such as other textile tools, tend to flake off.
- wear protection layer often go unnoticed, especially if the chrome layer has only loosened but not fallen off.
- suitable wear-resistant coatings increase the useful life of a textile tool, they may at the same time increase the sensitivity of the textile tool to harsh handling, particularly during shipping or assembly.
- the textile tool according to the invention has a body on which at least one tip or cutting edge or a stitch-forming part, for example, consisting of a hook and a tongue, is formed.
- a wear protection layer is provided on the body, which extends at least over the tip or the cutting edge.
- the wear protection layer is eg a metal layer, eg a chromium layer.
- the tip, the cutting edge or the stitch-forming part is provided with a cap made of a removable protective compound.

Abstract
Description
Die Erfindung betrifft ein Textilwerkzeug, das eine Spitze oder Schneide oder einen maschenbildenden Teil aufweist.The invention relates to a textile tool having a point or edge or a stitch-forming part.
Textilwerkzeuge haben häufig sehr feine Strukturen, wie insbesondere Spitzen, Schneiden, Haken, Zungen und dergleichen, die besonders standfest sein müssen. Die Standfestigkeit wird beispielsweise durch entsprechende Verschleißschutzschichten erzielt, die sich über Spitzen, Haken, Zungen oder Schneiden des Textilwerkzeugs weg erstrecken. Insbesondere erbringen solche Verschleißschutzschichten, wie Chromauflagen, Metallauflagen, Hartstoffauflagen oder Ähnliches eine hohe Abrasionsfestigkeit. Obwohl diese Verschleißschutzschichten dem Textilwerkzeug somit eine erhöhte Robustheit verleihen, können sie doch die Empfindlichkeit des Textilwerkzeugs gegen untypische Belastungen unerwartet erhöhen. Beispielsweise können Verschleißschutzschichten, insbesondere im Bereich großer Krümmungen, wie Spitzen, Haken oder Schneiden, bei untypischen Belastungen, wie Schlag oder Stoß oder bei Berührung mit anderen harten Gegenständen, wie andere Textilwerkzeugen, zum Abplatzen neigen. Solche Abplatzer der Verschleißschutzschicht bleiben häufig unbemerkt, insbesondere, wenn die Chromschicht nur gelockert aber noch nicht abgefallen ist. Während geeignete Verschleißschutzschichten somit die Einsatzdauer eines Textilwerkzeugs erhöhen, können sie unter Umständen zugleich die Empfindlichkeit des Textilwerkzeugs gegen raue Behandlung, insbesondere während des Transports oder der Montage erhöhen.Textile tools often have very fine structures, such as in particular tips, edges, hooks, tongues and the like, which must be particularly stable. The stability is achieved for example by appropriate wear protection layers that extend over tips, hooks, tongues or cutting the textile tool away. In particular, such wear protection layers, such as chrome plating, metal overlays, hard coatings or the like provide a high abrasion resistance. Although these wear protection layers thus lend the textile tool increased robustness, they can unexpectedly increase the sensitivity of the textile tool to atypical loads. For example, wear protection layers, in particular in the region of large curvatures, such as points, hooks or edges, at untypical loads, such as impact or impact or in contact with other hard objects, such as other textile tools, tend to flake off. Such chipping the wear protection layer often go unnoticed, especially if the chrome layer has only loosened but not fallen off. Thus, while suitable wear-resistant coatings increase the useful life of a textile tool, they may at the same time increase the sensitivity of the textile tool to harsh handling, particularly during shipping or assembly.
Es ist bekannt, mehrere Textilwerkzeuge, insbesondere Strickwerkzeuge, zum Zwecke des Versands zu einem Block zusammenzufassen. Dazu stellt die

Davon ausgehend ist es Aufgabe der Erfindung ein Konzept zum Schutz von Textilwerkzeugen wenigstens während des Transports und dem isolierten Handling vor dem Einbauen in Textilmaschinen und/oder während des Einbaus anzugeben.On this basis, it is an object of the invention to provide a concept for the protection of textile tools at least during transport and the isolated handling prior to installation in textile machines and / or during installation.
Diese Aufgabe wird mit dem Textilwerkzeug nach Anspruch 1 gelöst:This object is achieved with the textile tool according to claim 1:
Das erfindungsgemäße Textilwerkzeug weist einen Körper auf, an dem wenigstens eine Spitze oder Schneide oder ein maschenbildender Teil, z.B. bestehend aus einem Haken und einer Zunge, ausgebildet ist. Außerdem ist an dem Körper eine Verschleißschutzschicht vorgesehen, die sich wenigstens über die Spitze oder die Schneide erstreckt. Die Verschleißschutzschicht ist z.B. eine Metallschicht, z.B. eine Chromschicht.The textile tool according to the invention has a body on which at least one tip or cutting edge or a stitch-forming part, for example, consisting of a hook and a tongue, is formed. In addition, a wear protection layer is provided on the body, which extends at least over the tip or the cutting edge. The wear protection layer is eg a metal layer, eg a chromium layer.
Die Spitze, die Schneide oder der maschenbildende Teil ist mit einer Kappe aus einer entfernbaren Schutzmasse versehen. Diese Kappe bedeckt die Spitze, die Schneide bzw. den maschenbildenden Teil vorzugsweise ganz und schützt diese somit gegen Beschädigung durch Stoß oder Schlag. Andere harte Gegenstände, die während des Transports oder bei der Montage auf das Textilwerkzeug, insbesondere seine Spitze oder Schneide bzw. seinen maschenbildenden Teil einwirken, können somit kaum noch Beschädigungen der Verschleißschutzschicht bewirken. Auf diese Weise wird vermieden, dass das betreffende Textilwerkzeug (z.B. Nadel, Wirknadel, Schlingengreifer oder Stricknadel)während des Transports oder bei der Montage auf eine Weise vorgeschädigt wird, die dann während des Einsatzes zu dem vorzeitigen Verschleiß des Textilwerkzeugs führen könnte. Insbesondere wird die Entstehung von Mikrorissen in der Verschleißschutzschicht verhindert. Ebenso wird verhindert, dass sich Teile der Verschleißschutzschicht teilweise oder ganz lösen und somit das Material des darunter liegenden Körpers dem abrasiven Angriff von Textilfäden ausgesetzt wird. Wenn der maschenbildende Teil eines Strickwerkzeugs entsprechend von Schutzmasse eingehüllt ist, wird weiter verhindert, dass Haken und/Zunge von Stricknadeln beschädigt werden.The tip, the cutting edge or the stitch-forming part is provided with a cap made of a removable protective compound. This cap preferably completely covers the tip, the cutting edge or the stitch-forming part and thus protects them against damage by impact or impact. Other hard objects that act on the textile tool, in particular its tip or blade or its mesh-forming part during transport or during assembly, thus can hardly cause damage to the wear protection layer. In this way it is avoided that the textile tool in question (for example needle, knitting needle, loop taker or knitting needle) is pre-damaged during transport or assembly in a manner which could lead to premature wear of the textile tool during use. In particular, the formation of microcracks in the wear protection layer is prevented. It is also prevented that parts of the wear protection layer partially or completely dissolve and thus the material of the underlying body is exposed to the abrasive attack of textile threads. If the stitch forming part of a knitting tool is covered with protective compound, the hook and / or the tongue are further prevented from being damaged by knitting needles.
Die Schutzmasse haftet vorzugsweise adhäsiv an dem maschenbildenden Teil, der Spitze oder der Schneide und ihrer unmittelbaren Umgebung. Die Schutzmasse bildet dabei einen dämpfenden elastischen oder auch plastischen Körper. Vorzugsweise besteht sie aus Kunststoff, zum Beispiel einer thermoplastischen Schmelztauchmasse. Die Schutzmasse bildet dabei eine Dickschichtbeschichtung. Vorzugsweise ist die von der Schutzmasse gebildete Schicht deutlich dicker als die Verschleißschutzschicht. Vorzugsweise übersteigt die Dicke der Schutzmasse das 10 fache der Dicke der Verschleißschutzschicht. Unabhängig davon und vorzugsweise ist die Dicke der Schutzmasse (gemessen senkrecht zu der Oberfläche des Textilwerkzeugs) größer als der Krümmungsradius der Spitze oder Schneide.The protective compound preferably adheres adhesively to the stitch-forming part, the point or the cutting edge and their immediate surroundings. The protective compound forms a damping elastic or plastic body. Preferably it consists of plastic, for example a thermoplastic hot-dip mass. The protective compound forms a thick-film coating. Preferably, the layer formed by the protective compound is significantly thicker than the wear protection layer. Preferably, the thickness of the protective compound exceeds 10 times the thickness of the wear protection layer. Regardless and preferably, the thickness of the protective compound (measured perpendicular to the surface of the textile tool) is greater than the radius of curvature of the tip or blade.
Die aus der entfernbaren Schutzmasse bestehende Kappe wird vorzugsweise durch erstarrte, zuvor flüssige und somit formlose Schutzmasse gebildet. An einer Spitze wird die Kappe beispielsweise durch einen erstarrten Schutzmassetropfen gebildet. Ist die zu schützende Partie des Textilwerkzeugs eine Schneide, wird die Kappe vorzugsweise durch eine Wulst bestehend aus erstarrter vormals flüssiger und somit formloser Schutzmasse gebildet.The cap consisting of the removable protective compound is preferably formed by solidified, previously liquid and therefore informal protective compound. At a tip, the cap is formed, for example, by a solidified protective drop. If the part of the textile tool to be protected is a cutting edge, the cap is preferably formed by a bead consisting of solidified formerly liquid and thus informal protective compound.
Vorzugsweise wird die Schutzmasse zum Aufbringen auf das Textilwerkzeug thermisch verflüssigt. Es ist möglich, die Kappe aus Schutzmasse in einem einzigen Auftrag aufzubringen. Es kann auch zweckmäßig sein, die Kappe (d.h. den Tropfen oder die Wulst) durch mehrere nacheinander aufgebrachte Schutzmasseschichten zu bilden. Die Schutzmasseschicht kann durch kurzzeitiges Eintauchen des Textilwerkzeugs in flüssige Schutzmasse auf das Textilwerkzeug aufgebracht werden. Es ist auch möglich, die Schutzmasse auf das Textilwerkzeug aufzustreichen, aufzutropfen oder aufzusprühen.Preferably, the protective composition is thermally liquefied for application to the textile tool. It is possible to apply the protection compound cap in a single application. It may also be desirable to form the cap (i.e., the drop or the bead) by a plurality of successively applied protective layers. The protective compound layer can be applied to the textile tool by brief immersion of the textile tool in liquid protective compound. It is also possible to spread the protective compound on the textile tool, drip or spray.

Die Wirknadel 2 weist einen Körper 3 auf, der vorzugsweise aus Stahl besteht. An einem Ende 4, das der Einwirkung auf ein Textil und einen Faden dient und deshalb den Wirkabschnitt bildet, ist der Körper 3 mit einer Spitze 5 versehen, in deren Nachbarschaft ein Haken 6 vorgesehen sein kann.
