Abstract

To produce a twisted yarn, in a combined spinning/twisting process, at least two spinners (52,53) each deliver spun yarns (a,a') which are fed to a centering point on the axis of a two-for-one twister. They are twisted initially in one direction to pass to a second centering point to be given an opposed twist. They pass through the second centering point within a yarn balloon between the centering points to be wound on to a bobbin (22) with is rotated within the yarn balloon.

Bei einem in der DE 43 31 801 C1 beschriebenen Verfahren zur Herstellung eines Zwirns in einem integrierten Spinn-Zwirnprozess sind zur Herstellung von zwei Spinnfäden zwei Spinnaggregate in Form von OE-Spinnrotoren innerhalb eines Doppeldraht-Zwirnsaggregates angeordnet, das dazu dient, die von den beiden Spinnaggregaten erzeugten Spinnfäden nach Art des Doppeldrahtprinzips zu verzwirnen. Bei diesem bekannten Verfahren bzw. der entsprechenden bekannten Vorrichtung wird das aufgelöste Fasermaterial den Spinnaggregaten durch die vom Fadenballon definierte Hüllfläche hindurch zugeführt. Infolge der Integration der Spinnaggregate in die Zwirneinrichtung sind den Spinnrotoren hinsichtlich ihrer Abmessungen, insbesondere der Durchmesser, bestimmte bauliche Grenzen gesetzt.Der bekannte integrierte Spinn-Zwirnprozess ist damit nur bedingt für die Vearbeitung von Kammgarnen geeignet, da Kammgarne in der Regel eine Stapellänge zwischen 120-160 mm besitzen, was Rotoren mit entsprechend größeren Durchmessern voraussetzt. Bei dem bekannten System können unter Umständen auch Schwierigkeiten beim Hindurchführen von Fasern mit größerer Stapellänge durch den Fadenballon auftreten.In one described in DE 43 31 801 C1 Process for making a twine in one Integrated spinning and twisting processes are in the making of two spinning threads two spinning units in Form of OE spinning rotors within a double wire twisting unit arranged, which serves the filaments produced by the two spinning units to twist according to the type of double wire principle.
