Abstract

The cooling tube (4), for blowing and cooling freshly-extruded melt-spun continuous polymer filaments (3), has at least one perforated tube (7) in a sieve structure for the cooling air to pass through. At least one covering ring (9) is at the inner or outer side of the perforated tube, in a release mounting. The filament cooling tube has a covering ring at the perforated tube in the form of a metal strip curved into a circle, and the free ends are bonded together.

Description

Die Erfindung betrifft ein Kühlrohr zum Anblasen und Kühlen frisch gesponnener synthetischer Endlosfäden, wobei das Kühlrohr mindestens ein siebartig gelochtes Rohr für den Durchtritt von Kühlluft aufweist.The invention relates to a cooling tube for blowing and cooling freshly spun synthetic continuous filaments, wherein the cooling tube for at least one sieve-like perforated tube for has the passage of cooling air.

Wenn das Kühlrohr an unterschiedliche Kühlbedingungen angepaßt werden mußte, wechselte man bisher das ganze Kühlrohr oder aber zumindest das siebartig gelochte Rohr aus. Die Veränderung der Kühlbedingungen war z. B. dann nötig, wenn sich die Anzahl der Fäden und/oder deren Titer erheblich änderte.If the cooling pipe had to be adapted to different cooling conditions, changed So far, the entire cooling tube or at least the sieve-like perforated tube. The Change in cooling conditions was e.g. B. necessary if the number of threads and / or changed the titer significantly.

Auch dann, wenn man die Länge der Kühlstrecke verändern wollte, war das Auswechseln des gelochten Rohres notwendig.Even if you wanted to change the length of the cooling section, you had to replace the perforated pipe necessary.

Der Erfindung liegt die Aufgabe zugrunde, das Kühlrohr auf einfache, kostengünstige Weise an unterschiedliche Kühlbedingungen anpassen zu können. Die Aufgabe wird dadurch gelöst, daß mindestens ein Abdeckring an der Innenseite oder Außenseite des siebartig gelochten Rohres lösbar angeordnet ist. Der Abdeckring kann mit der gewünschten Breite ausgebildet werden, um einen entsprechenden Teil der Innenseite oder Außenseite des siebartig gelochten Rohres abzudecken.The invention has for its object the cooling tube in a simple, inexpensive manner to be able to adapt to different cooling conditions. The task is solved that at least one cover ring is perforated on the inside or outside of the sieve Tube is detachably arranged. The cover ring can be formed with the desired width be perforated to a corresponding part of the inside or outside of the sieve To cover the pipe.

Befinden sich die zu kühlenden Fäden innerhalb des Kühlrohres, kann man den Abdeckring z. B. an der Innenseite des gelochten Rohres anbringen. Laufen die Fäden außen am Kühlrohr vorbei, kann der Abdeckring z. B. außen am gelochten Rohr angeordnet werden.If the threads to be cooled are inside the cooling tube, you can use the cover ring e.g. B. attach to the inside of the perforated tube. Run the threads on the outside of the cooling tube over, the cover ring z. B. be arranged on the outside of the perforated tube.

An einem Kühlrohr können auch mehrere Abdeckringe in mehr oder weniger großem Ab­ stand angeordnet werden, wobei man z. B. mittels Stützstegen den gegenseitigen Abstand fixiert.Several cover rings can be attached to a cooling tube in more or less large dimensions stood to be arranged, with z. B. by means of support webs the mutual distance fixed.

Ausgestaltungsmöglichkeiten des Kühlrohres mit zugehörigen Abdeckringen werden mit Hilfe der Zeichnung erläutert. Es zeigt:Design options for the cooling tube with associated cover rings are included Help explained in the drawing. It shows:

Fig. 1 den Längsschnitt durch ein Kühlrohr in schematischer Darstellung, Fig. 1 is a longitudinal section through a cooling tube in a schematic representation;

Fig. 2 einen Abdeckring in perspektivischer Darstellung und Fig. 2 is a cover ring in perspective and

Fig. 3 ein Kühlrohr, an welchem die Fäden außen vorbeilaufen. Fig. 3 shows a cooling tube, on which the threads run outside.

Eine Polymerschmelze wird in an sich bekannter Weise durch einen Spinnbalken (1) und ein Spinnpaket (2) mit Düsenlöchern gepreßt, so daß zahlreiche Fäden (3) gebildet werden. Die Fäden werden nach unten abgezogen und aufgewickelt (nicht dargestellt).A polymer melt is pressed in a manner known per se through a spinning beam ( 1 ) and a spinning package ( 2 ) with nozzle holes, so that numerous threads ( 3 ) are formed. The threads are pulled down and wound up (not shown).

Das Kühlrohr (4) der Fig. 1 umgibt die Fäden, es besteht aus einer zylindrischen Rückwand (5) mit Lufteinlaß (6) und einem siebartig gelochten Rohr (7) für den Durchtritt der zu den Fäden strömenden Kühlluft. Der Ringraum (8) kann strömungsleitende Einbauten enthalten, die der besseren Übersichtlichkeit wegen weggelassen wurden. The cooling tube (4) of Fig. 1 surrounds the filaments, it consists of a cylindrical rear wall (5) with air inlet (6) and a sieve-like, perforated tube (7) for the passage of the air flowing to the filaments cooling air. The annular space ( 8 ) can contain flow-conducting internals which have been omitted for the sake of clarity.

An der Innenseite des gelochten Rohres (7) ist ein Abdeckring (9) lösbar angeordnet, der den Durchtritt von Kühlluft an dieser Stelle verhindert. Fig. 2 zeigt den Abdeckring (9) in perspektivischer Darstellung, er besteht aus einem Metallband, dessen freie Enden zusam­ mengeführt und verstellbar und lösbar aneinander befestigt sind. In Fig. 2 sind Schraubver­ bindungen (10) und (11) an der Innenseite des Ringes vorgesehen, doch sind hier z. B. auch Federverbindungen möglich. Diese Verbindungen sind in der Lage die Bandenden zusammenzuhalten und gleichzeitig den Ring und dessen Radius aufzuweiten, so daß der Abdeckring (9) an der Innenseite des Rohres (7) angepreßt sitzt.On the inside of the perforated tube ( 7 ), a cover ring ( 9 ) is detachably arranged, which prevents the passage of cooling air at this point. Fig. 2 shows the cover ring ( 9 ) in perspective, it consists of a metal strip, the free ends are brought together and adjustable and releasably attached to each other. In Fig. 2 screw connections ( 10 ) and ( 11 ) are provided on the inside of the ring, but here z. B. also spring connections possible. These connections are able to hold the band ends together and at the same time widen the ring and its radius, so that the cover ring ( 9 ) is pressed against the inside of the tube ( 7 ).

Durch Verstellen oder Lösen der Verbindungen (10) und (11) kann der Abdeckring entfernt und z. B. durch einen anders geformten Abdeckring ersetzt werden, der z. B. eine andere Breite (b) aufweist.By adjusting or loosening the connections ( 10 ) and ( 11 ), the cover ring can be removed and z. B. be replaced by a differently shaped cover ring, the z. B. has a different width (b).

Abweichend von Fig. 1 kann der Abdeckring auch so angeordnet werden, daß er an der Außenseite des siebartig gelochten Rohres (7) anliegt.Deviating from FIG. 1, the covering can also be arranged so that it abuts against the outside of the sieve-like, perforated tube (7).

Mit dem Abdeckring wird der Ort und die Intensität der Kühlung der Fäden (3) in gewünsch­ ter Weise variiert, es können gleichzeitig auch mehrere Abdeckringe eingesetzt werden. In Fig. 1 ist der Bereich des gelochten Rohres (7), durch den Kühlluft zu den Fäden strömt, punktiert angedeutet.With the cover ring, the location and the intensity of the cooling of the threads ( 3 ) is varied in the desired manner, several cover rings can also be used at the same time. In Fig. 1 the area of the perforated tube ( 7 ) through which cooling air flows to the threads is indicated by dotted lines.

Bei der Ausführungsform der Fig. 3 umgeben die abwärts laufenden Fäden (3) das Kühlrohr (4), dem man Luft von oben, unten oder seitlich zuführt. Die Luft tritt durch das gelochte Rohr (7) nach außen, um die Fäden anzublasen.In the embodiment of Fig. 3, the downward threads ( 3 ) surround the cooling tube ( 4 ), to which air is supplied from above, below or from the side. The air exits through the perforated tube ( 7 ) to blow the threads.

Der Abdeckring (9) ist hier außen auf das Rohr (7) aufgespannt und lösbar befestigt, die Aus­ führung der Befestigung ist nicht dargestellt.The cover ring ( 9 ) is clamped on the outside of the tube ( 7 ) and releasably attached, the imple mentation of the attachment is not shown.

Abweichend von Fig. 3 kann der Abdeckring auch so angeordnet werden, daß er an der Innenseite des siebartig gelochten Rohres (7) anliegt.Deviating from FIG. 3, the cover ring can also be arranged so that it abuts the inner side of the sieve-like, perforated tube (7).
