Abstract
Bei einer Vorrichtung an einer Karde für Baumwolle, Chemiefasern u. dgl., die zwischen einem Abnehmer und zwei Quetschwalzen angeordnet ist, bei der unterhalb der Abstreichwalze ein ortsfestes Element vorhanden ist, dessen obere Fläche einem Bereich der Abstreichwalze zugewandt ist und das mit seinem einen Endbereich dem Walzenspalt im Bereich zwischen Abnehmer und Abstreichwalze zugeordnet ist, wobei ein Faservlies bis zum Walzenspalt zwischen den Quetschwalzen einen freien Raum durchläuft, und das Element als Stütz- und Leitkörper ausgebildet ist, ist der andere Endbereich in dem Bereich zwischen Abstreichwalze und Quetschwalzen angeordnet und in Richtung auf den Walzenspalt zwischen den Quetschwalzen ausgerichtet. Um auf einfache Art eine verbesserte Führung des Faserflors zu ermöglichen, insbesondere bei größerer Arbeitsbreite und/oder erhöhter Liefergeschwindigkeit, weist die obere Fläche mindestens teilweise Öffnungen auf, die den Durchtritt von Luft gestatten.In a device on a card for cotton, manmade fibers u. Like., Which is arranged between a pickup and two nip rolls, in which below the doctor roller a stationary element is present, the upper surface of which faces a region of the doctor roller and which is associated with its one end region of the nip in the region between the pickup and the doctor roller, wherein a nonwoven fabric passes through a free space to the nip between the squeezing rollers, and the element is formed as a support and guide body, the other end portion is arranged in the region between the doctor roller and nip rolls and aligned in the direction of the nip between the nip rolls. In order to allow a simple way improved guidance of the batt, especially for larger working width and / or increased delivery speed, the upper surface at least partially open, which allow the passage of air.
Description
Die Erfindung betrifft eine Vorrichtung an einer Karde für Baumwolle, Chemiefasern u. dgl., die zwischen einem Abnehmer und zwei Quetschwalzen angeordnet ist, bei der unterhalb der Abstreichwalze ein ortsfestes Stütz- und Leitelement vorhanden ist, dessen obere Fläche einem Bereich der Abstreichwalze und dessen vordere Fläche der unteren Quetschwalze zugewandt ist und bei der die Kante zwischen oberer Fläche und vorderer Fläche in dem Bereich zwischen Abstreichwalze und Quetschwalzen angeordnet und Richtung auf den Walzenspalt zwischen den Quetschwalzen ausgerichtet ist, wobei ein Faservlies über die obere Fläche und anschließend bis zum Walzenspalt zwischen den Quetschwalzen einen freien Raum durchläuft.The invention relates to a device on a carding machine for cotton, manmade fibers u. Like., Which is arranged between a pickup and two nip rolls, in which below the doctor roller a stationary support and guide element is present, the upper surface of a region of the doctor roller and the front surface of the lower nip roller faces and in which the edge between upper Surface and front surface in the area between the doctor roller and nip rolls arranged and aligned with the direction of the nip between the nip rolls, wherein a nonwoven fabric passes through the upper surface and then to the nip between the nip rolls a free space.
Eine bekannte Vorrichtung (
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere auf einfache Art eine verbesserte Führung des Faserflors ermöglicht, insbesondere bei größerer Arbeitsbreite und/oder erhöhter Liefergeschwindigkeit.The invention is therefore an object of the invention to provide a device of the type described above, which avoids the disadvantages mentioned, which allows in particular a simple way improved guidance of the batt, especially for larger working width and / or increased delivery speed.
Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.The solution of this object is achieved by the characterizing features of
Durch die erfindungsgemäßen Maßnahmen wird die Austrittsöffnung für die mitgeschleppte Luft derart gestaltet, dass durch die Geometrie des Vliesleitprofils die Luftströmung entgegen der Rotationsrichtung der unteren Quetschwalze nach unten gerichtet wird. Vorzugsweise wird das Strömungsprofil über die Maschinenbreite durch Variation des Spaltes zwischen Vliesleitprofil und Quetschwalze beeinflusst. Dies wird bevorzugt dadurch erreicht, dass die Vorderkante des Profils beispielsweise konkav oder konvex ausgeführt ist.By the measures according to the invention, the outlet opening for the entrained air is designed such that the air flow is directed against the direction of rotation of the lower nip roll down by the geometry of Vliesleitprofils. Preferably, the flow profile over the machine width is influenced by varying the gap between Vliesleitprofil and squeegee. This is preferably achieved in that the front edge of the profile is designed, for example, concave or convex.
Die Ansprüche 2 bis 15 haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The
