Description
Die Erfindung betrifft eine Frottierwebmaschine mit einer zwischen Riet und Brustbaum in 'Schussrichtung verlaufenden Breithaltevorrichtung, wobei das Gewebe durch Bewegung des Brustbaums und der Breithaltevorrichtung periodisch bezüglich der Rietanschlagstelle verschoben wird und die Frottierwebmaschine mit einer Vorrichtung zur Bildung einer Einlegekante ausgestattet ist.The invention relates to a terry loom with a straight line extending between the reed and the breast beam in 'shooting direction spreader device, wherein the fabric of the reed stop point is shifted by movement of the breast beam and the spreader device periodically with respect to and the loom is equipped with a device for forming an insertion edge.
Bei derartigen Frottierwebmaschinen erfolgt die Schlingenbildung nach dem Prinzip der Gewebesteuerung. Während sich das Riet in herkömmlicher Weise bewegt, wird das Gewebe durch die gemeinsame Bewegung des Brustbaums und der Breithaltevorrichtung periodisch von der Rietanschlagstelle weggezogen, so dass nach jedem Vollanschlag des Riets für die nachfolgende Schlingenbildung der Florkette zwei oder drei Teilanschläge erzeugt werden (Dreischuss- oder Vierschuss-Frottierware). Die Bildung der Einlegekante erfolgt dabei in an sich bekannter Weise wie bei Normalgeweben, z. B. wie in der US-PS 3457966 offenbart, indem die am Rand des Gewebes vorstehenden Enden eines Schussfadens bis zur Beendigung des Schusseintrages in gestreckter Lage festgehalten, anschliessend in das nächste Fach eingelegt und dort zusammen mit dem folgenden Schussfaden angeschlagen werden. Somit wird das Einlegeende des Fadens durch Fachwechsel im jeweils folgenden Webmasch. gegen Herausgleiten gesichert.In terry weaving machines of this type, the loop is formed on the principle of fabric control. While the reed moves in a conventional manner, the tissue is periodically pulled away from the reed attachment point by the joint movement of the breast tree and the spreader device, so that after each full stop of the reed, two or three partial stops are generated for the subsequent looping of the pile chain (three-shot or Four-shot terry towels). The formation of the insert edge takes place in a manner known per se as in normal tissues, for. B. as disclosed in US-PS 3457966 by the projecting at the edge of the fabric ends of a weft until the end of the weft insertion in a stretched position, then inserted into the next compartment and struck there together with the following weft. Thus, the insertion end of the thread by changing the subject in the following weaving. secured against sliding out.
Im Falle der eingangs genannten Frottierwebmaschine ist diese Sicherung des Einlegeendes aufgrund des während der Teilanschläge offenbleibenden Randfadenfachs bei bestimmten Garnen bzw. Kantenbindungen nicht gewährleistet. Hierdurch ergibt sich der Nachteil, dass die Einlegeenden in gewissen Fällen ganz oder teilweise unter Schlingenbildung hervorstehen.In the case of the terry weaving machine mentioned at the outset, this securing of the insert end is not guaranteed for certain yarns or edge bindings due to the edge thread compartment remaining open during the partial sewing operations. This has the disadvantage that in some cases the inserts protrude wholly or partially with loop formation.
Aufgabe der Erfindung ist es, die eingangs genannte Frottierwebmaschine so zu verbessern, dass hervorstehende Einlegeenden bzw. Schlingen mit Sicherheit vermieden werden und bei sämtlichen Garnen bzw. Kantenbindungen einwandfreie Einlegekanten erzielt werden.The object of the invention is to improve the terry weaving machine mentioned at the outset in such a way that protruding insert ends or loops are avoided with certainty and perfect insert edges are achieved with all yarns or edge bindings.
Zur Lösung dieser Aufgabe dient die im Kennzeichen von Anspruch 1 aufgeführte Massnahme.The measure listed in the characterizing part of
Hierdurch lässt sich erreichen, dass die Randkettfäden zangenartig gegen das betreffende Einlegeende gedrückt werden, so dass dieses auch bei von der Rietanschlagstelle weggezogenem Gewebe zwischen den Randkettfäden gehalten wird. Somit wird eine saubere Einlegekante ohne hervorstehende Einlegeenden bzw. Schlingen erhalten.This allows the edge warp threads to be pressed like pliers against the insertion end in question, so that this is held between the edge warp threads even when the fabric is pulled away from the reed attachment point. This ensures a clean insert edge without protruding insert ends or loops.
Zwar ist darauf hinzuweisen, dass in der FR-A 643 846 und CH-A 345618 bereits eine das Fach im Bereich der Randkettenfäden verengende Umlenkvorrichtung offenbart ist. Allerdings ist diese Vorrichtung dort nicht im Zusammenhang mit einer Frottierwebmaschine der im vorliegenden Anspruch 1 genannten Art offenbart. Ferner muss die bekannte Umlenkvorrichtung beweglich angeordnet sein, so dass sie aus einer Arbeitsposition, in der sie das Fach verengt, in eine Positions gebracht werden kann, in der sie die Kettfäden freigibt.It should be pointed out that FR-A 643 846 and CH-A 345618 already disclose a deflection device which narrows the compartment in the area of the edge warp threads. However, this device is not disclosed there in connection with a terry weaving machine of the type mentioned in the
Nach einer besonders vorteilhaften Ausführung der Erfindung kann die Umlenkvorrichtung eine einen Schlitz enthaltende Führungsplatte aufweisen. Dies ergibt eine einfache Fertigung der Umlenkvorrichtung.According to a particularly advantageous embodiment of the invention, the deflection device can have a guide plate containing a slot. This results in simple manufacture of the deflection device.
Die Umlenkvorrichtung kann auch mit verstellbaren, einen Schlitz bildenden Backen versehen sein. Hierdurch ergibt sich der Vorteil einer besonders flexiblen Anpassung an verschiedene Garndicken und Gewebearten.The deflection device can also be provided with adjustable, slit-forming jaws. This gives the advantage of a particularly flexible adaptation to different yarn thicknesses and types of fabric.
Schliesslich kann die Umlenkvorrichtung mit einer schiebelehrenartigen Skala ausgebildet sein. Hierdurch ist eine messbare bzw. reproduzierbare Einstellung des Schlitzes gewährleistet.Finally, the deflection device can be designed with a slide gauge scale. This ensures a measurable or reproducible setting of the slot.
