Description
Fadenbremse mit einem vom Faden umschlungenen und angetriebenen Spannkörper Um einem Faden die erforderliche Spannung zu geben, benutzte man bislang sogenannte Teller- oder Plattenbremsen, durch welche der Faden gezogen wird. Dergleichen Fadenbremsen sind in den verschiedensten Ausführungen bekannt. Für empfindliche Garne, insbesondere für Kunstseide, sind diese jedoch nicht geeignet, da beim Durchziehen des Fadens durch die Scheiben die Einzelfädchen eines Kunstseidenfadens leicht zerstört werden. Aus diesem Grunde benutzt man deshalb für Kunstseide auch Fadenbremsen, bei «-elchen der Faden um eine Rolle gelegt wird. «-elche von dem Faden mitgenommen wird (s. Abb. I). Diese Rolle liegt auf einer Filzunterlage 3 und wird durch Gewichte 2 belastet. Der Faden 4. erhält auf diese Weise eine gewisse Spannung. Es zeigt sich nun jedoch bei derartigen Fadenbremsen, daß, ` sobald das auflaufende Fadenende 5 locker wird, der Spannkörper i nicht mehr sicher mitgenommen wird und ein Rutschen des Fadens 4. erfolgt. Dieses Lockerwerden des auflaufenden Fadenendes ist aber eine periodische Dauererscheinung beim Abziehen des Fadens von Kreuzspulen und wird hervorgerufen durch die dabeiauftretende Ballonbildung. Der Hauptzweck der Fadenspannrollen, dem Faden eine gleichmäßige Spannung zu geben und die Reibung zu vermeiden, wird also nicht erfüllt.Thread brake with a tensioning body wrapped around and driven by the thread In order to give a thread the required tension, so-called so-called ones have been used up to now Plate or plate brakes through which the thread is pulled. Same thread brakes are known in various designs. For delicate yarns, especially for rayon, however, these are not suitable because the thread is pulled through the individual threads of an artificial silk thread can easily be destroyed by the discs. For this reason, thread brakes are also used for artificial silk, in the case of «-elchen» the thread is wrapped around a roll. «-Which is taken by the thread (s. Fig. I). This role lies on a felt pad 3 and is loaded by weights 2. This gives the thread 4. a certain tension. It is now showing, however with thread brakes of this type, that `` as soon as the running thread end 5 becomes loose, the clamping body i is no longer safely taken along and the thread slips 4. takes place. This loosening of the running thread end is, however, a periodic one Permanent phenomenon when pulling the thread from cross-wound bobbins and is caused due to the balloon formation that occurs at the same time. The main purpose of the tension rollers, the So will give the thread an even tension and avoid friction not fulfilled.
Dieses Ziel wird nun bei der Fadenbremse nach vorliegender Erfindung erreicht, bei welcher der Spannkörper mit im Kreis angeordneten Mitnehmern zur schlupffreien Mitnahme einer axial frei beweglichen Platte versehen ist, welche den um die Mitnehmer gelegten Faden gegen den Spannkörper drückt. Die Abb. II und I II zeigen ein Ausführungsbeispiel dieser Fadenbremse. Sie besteht aus dem Spannkörper 6 und einer Platte bzw. Tellerscheibe ;, die mittels Stifte 8, welche kreisförmig auf dem Spannkörper angeordnet sind, mitgenommen wird, so daß bei der Bewegung des Spannkörpers ein Gleiten der Platte ; gegenüber dem Spannkörper 6 nicht erfolgen kann. Der die Mitnehmer umschlingende Faden 9 wird nun vermittels des Drukkes, den die Platte auf ihn ausübt, auf dem Spannkörper festgehalten, auch dann, wenn das auflaufende Fadenende locker wird. Die den Druck. ausübende Platte muß also senkrecht frei beweglich in den Stiften 8 geführt sein. Die Führungsstifte können auch einen flachen Querschnitt aufweisen.This goal is now achieved with the thread brake according to the present invention achieved, in which the clamping body with drivers arranged in a circle for slip-free Entrainment of an axially freely movable plate is provided, which around the driver laid thread presses against the tensioning body. Figs. II and I II show an embodiment this thread brake. It consists of the clamping body 6 and a plate or washer ;, which by means of pins 8, which are arranged in a circle on the clamping body, is taken along so that the plate slides during the movement of the clamping body ; against the clamping body 6 can not take place. The one wrapping around the driver Thread 9 is now by means of the pressure that the plate exerts on him on the Tensioning body held, even if the accruing thread end is loose. The pressure. exercising plate must so vertically freely movable in the pins 8 be performed. The guide pins can also have a flat cross section.
Da der Druck auf den Faden 9 durch die Platte 6, der Reibungsdruck auf den Spannkörper jedoch vermittels der Bremsgewichte erfolgt, so kann eine Änderung des Druckes auf den Faden unabhängig durch Gewichtsauswahl entsprechender Platten erfolgen.Because the pressure on the thread 9 through the plate 6, the frictional pressure is carried out on the clamping body by means of the brake weights, a change can be made independent of the pressure on the thread by selecting the appropriate plate weight take place.
