Abstract

The machine possesses rotatable detaching cylinders (1, 2) and a gripper (4) having a gripper frame (5) which is movable to and fro in the machine stand between a front end position near the detaching cylinders (1, 2) and a rear end position distant from the detaching cylinders (1, 2). A top comb (15, 16) is arranged between the gripper (4) and the detaching cylinders (1, 2). When the gripper frame (5) is in its front end position, a fibre-supporting element (18) is moved into a position next to the top comb (15, 16). The fibre-supporting element (18) then supports the fibre tuft which is located in the gripper (4) and which is detached by the detaching cylinders (1, 2) through the top comb (15, 16). Neps contained in the fibre tuft therefore cannot pass through under the top comb (15, 16), but are removed from the fibre tuft in the top comb (15, 16). In addition, a clamping element (19) interacts with the fibre-supporting element (18) and slightly compresses the fibre tuft.

Description

Die Erfindung bezieht sich auf eine Kämm-maschine mit einem Maschinengestell, in dem Gestell drehbar gelagerten Abreisszylindern, einer Zange mit einem Zangenrahmen, der in dem Gestell zwischen einer vorderen Endlage bei den Abreisszylindern und einer von den Abreisszylindern entfernten hinteren Endlage hin-und herbewegbar ist, und einem zwischen der Zange und den Abreisszylindern angeordneten Fixkamm.The invention relates to a combing machine with a machine frame, in the frame rotatably mounted tear-off cylinders, a pair of pliers with a pliers frame which can be moved back and forth in the frame between a front end position in the tear-off cylinders and a rear end position removed from the tear-off cylinders , and a fixed comb arranged between the pliers and the tear-off cylinders.

Der Fixkamm dient in Kämmaschienen dieser Art Der Fixkamm dient in Kämmaschinen dieser Art dazu, das hintere Ende eines von der Zange getragenen Faserbartes, dessen vorderes Ende zuvor von einem ro-tierenden Rundkamm ausgekämmt worden ist, auszukämmen, während der Faserbart durch die Abreisszylinder abge-rissen und durch den Fixkamm hindurchgezogen wird. Da-bei werden Nissen und Verunreinigungen aus dem hinteren Ende des Faserbartes weitgehend entfernt. Die Entfer-nung von Nissen und Verunreinigungen ist jedoch nie ganz vollständig.The fixed comb is used in combing machines of this type. The fixed comb is used in combing machines of this type to comb the rear end of a fiber beard carried by the pliers, the front end of which has previously been combed out by a rotating circular comb, while the fiber beard is torn off by the tear-off cylinders. tear and is pulled through the fixed comb. Nits and impurities are largely removed from the rear end of the fiber beard. However, the removal of nits and contaminants is never entirely complete.

Die Aufgabe der Erfindung besteht darin, eine Kämmaschine der eingangs angegebenen Art so auszubilden, dass eine vollständigere Entfernung von Nissen und Verunreinigungen erzielt wird als mit bekannten Kämmaschinen.The object of the invention is to design a combing machine of the type specified in the introduction in such a way that more complete removal of nits and impurities is achieved than with known combing machines.

Die erfindungsgemässe Kämmaschine, mit der die Aufgabe gelöst wird, ist gekennzeichnet durch ein Faserstützelement, das bei in der vorderen Endlage stehendem Zangenrahmen in eine Endlage neben dem Fix-kamm bewegbar ist, um durch den Fixkamm gesogene Fasern zu unterstützen.The combing machine according to the invention, with which the object is achieved, is characterized by a fiber support element which, when the tongs frame is in the front end position, can be moved into an end position next to the fixed comb in order to support fibers drawn through the fixed comb.

Mit dem Faserstützelement können während des Abreissens die hinteren Enden von Fasern unterstützt werden, welche die Zange verlassen haben, so dass solche Fasern nicht mehr nach unten hängen und ungekämmt unter dem Fixkamm hindurchlaufen können.With the fiber support element, the rear ends of fibers that have left the pliers can be supported during the tearing, so that such No longer hang fibers down and can run uncombed under the fixed comb.

Das Faserstützelement kann in seiner genannten Endlage zwischen dem Fixkamm und den Abreiss-zylindern oder auch auf der anderen Seite des Fixkamms stehen. Insbesondere wenn es zwischen dem Fixkamm und den Abreisszylindern steht, kann es in vorteilhafter Weise auch dazu deinen, das Ende des zuvor gebildeten Kammzugvlieses, das durch eine kurze Rückwärtsdrehung der Abreisszylinder aus der Klemmlinie derselben heraus-tritt, auf dem Abreisszylinder nach unten zu führen, so dass dieses Ende weniger vom Abreisszylinder abhebt.The fiber support element can stand in its end position between the fixed comb and the tear-off cylinders or on the other side of the fixed comb. In particular, when it is between the fixed comb and the tear-off cylinders, it can also advantageously be yours to guide the end of the previously formed comb-pulling fleece, which comes out of the clamping line of the latter by a brief reverse rotation of the tear-off cylinders, downward on the tear-off cylinder, so that this end lifts less from the tear-off cylinder.

In einer bevorzugten Ausführungsform enthält die erfindungsgemässe Kämmaschine zusätzlich ein mit dem Faserstützelement in dessen genannter Endlage zusammenwirkendes Klemmelement. Durch dieses wird der Faserbart, der beim Abreissen durch den Fixkamm hindurch-gezogen wird, leicht komprimiert und gebremst, wodurch die Abscheidung von Nissen und Verunreinigungen weiter verbessert wird. Dabei dienen das Faserstützelement und das Klemmelement auch direkt als Nissenabstreifer.In a preferred embodiment, the combing machine according to the invention additionally contains a clamping element which interacts with the fiber support element in its end position. This slightly compresses and brakes the fiber beard, which is pulled through the fixed comb when it is torn off, which further improves the separation of nits and impurities. The fiber support element and the clamping element also serve directly as a nip wiper.
