Abstract

Es wird eine Heizeinrichtung zum Erwärmen eines laufenden Fadens geschaffen, deren langgestreckter Heizkörper eine U-förmige Nut aufweist, in welcher mehrere Fadenführer angebracht sind. An den Fadenführern erfährt der durch die Heizeinrichtung laufende Faden jeweils eine Ablenkung. Die Anordnung der Fadenführer ist so gestaltet, daß jeweils mindestens zwei in Fadenlaufrichtung nebeneinanderliegende Fadenführer einer Anzahl n Fadenführer so angeordnet sind, daß die Anzahl von Vorzeichenänderungen des Richtungsgradienten der Fadenlaufkurve kleiner als die Anzahl (n-1) Fadenführer ist.

Figure 00000001
A heating device for heating a running thread is created, the elongated heating element of which has a U-shaped groove in which several thread guides are attached. The thread running through the heating device is each deflected on the thread guides. The arrangement of the thread guides is designed such that at least two thread guides of a number n thread guides lying next to each other in the thread running direction are arranged such that the number of changes in the sign of the direction gradient of the thread running curve is smaller than the number (n-1) of thread guides.
