Abstract

Bei einem Fadenliefergerät (1), das zum bedarfsgerechten Positivliefern von einem Faden (2) ein mit einem Elektromotor (9) verbundenes Fadenlieferrad (6) aufweist, weist einen Fadenlaufweg (3) auf, der durch Fadenleitmittel (25, 26) unter einem Winkel zu der Drehachse (7) des Fadenlieferrads (6) festgelegt ist, der grösser als die Summe aus 90° und einem zusätzlichen spitzen Winkel ist. Dieser zusätzliche spitze Winkel α ist grösser als der Steigunswinkel eines Fadenwickels auf dem Fadenlieferrad (6), bei dem benachbarte Windungen aneinander anliegen. Dadurch ergibt sich ein ruhiger Ablauf des auf dem Fadenlieferrad (6) liegenden Fadens (2).

Figure 00000001
In the case of a thread delivery device (1) which has a thread delivery wheel (6) connected to an electric motor (9) for positive delivery of a thread (2), has a thread travel path (3) which is at an angle by thread guide means (25, 26) is fixed to the axis of rotation (7) of the yarn feed wheel (6), which is greater than the sum of 90 ° and an additional acute angle. This additional acute angle α is greater than the pitch angle of a thread winding on the thread delivery wheel (6), in which adjacent turns abut one another. This results in a smooth running of the thread (2) lying on the thread delivery wheel (6).
