Abstract

A known warp knitting machine for the prodn. of material with single- or double-sided pile loops, has a roughening or raising roll installed in the vicinity of the discharge of the product from the take-off system, for liting up the pile loops held by the basic fibres on the base material. This system is improved by providing a further tensioning device consisting of a system of rolls in the material take-off direction downstream of the raising roll. These tensioning rolls can be driven at a higher peripheral speed than the material take-off system. Pref. a second raising roll is provided in the vicinity of the first tensioning roll. Method ensures that all the pile loops are raised.

Description

Die von der Maschenbildungsstelle 1 einer Kettenwirkmaschine kommende Ware 2 wird durch die Warenabzugsvorrichtung 3 von der Maschine abgezogen und zu dem Warenbaum 4 geführt. Der Abzugswalze 5 der Vorrichtung 3 gegenüberliegend ist die Kratzenwalze 6 angeordnet, die durch einen besonderen Motor angetrieben ist oder mit dem Maschinenantrieb in Verbindung steht. Dieser Kratzenwalze 6 nachgeschaltet ist eine in Abzugsrichtung wirkende Spannvorrichtung 7 angeordnet, die aus einem Walzensatz besteht. Der Umlenkwalze 8 dieses Satzes ist eine weitere Kratzenwalze 9 zugeordnet. Von hier aus gelangt die Ware 2 zu dem schon benannten Warenbaum 4. Die ebenfalls mit einem besonderen Motor angetriebene oder mit dem Maschinenantrieb in Verbindung stehende Spannvorrichtung 7 erhält eine etwas höhere Umlaufgeschwindigkeit als die Walze 6, so daß in dem Warenabschnitt 2a eine besondere Spannung aufrecht erhalten wird. The one coming from the loop formation point 1 of a warp knitting machine Goods 2 are withdrawn from the machine by the goods withdrawal device 3 and closed the goods tree 4 out. The take-off roller 5 of the device 3 is opposite the scraper roller 6 is arranged, which is driven by a special motor or is in connection with the machine drive. This scraper roller 6 is connected downstream a clamping device 7 acting in the withdrawal direction is arranged, which consists of a Roll set consists. The deflection roller 8 of this set is another scraper roller 9 assigned. From here the goods 2 arrive at the goods tree 4 already mentioned. The one that is also driven by a special motor or with the machine drive related clamping device 7 receives a slightly higher rotational speed than the roller 6, so that a particular tension is maintained in the goods section 2a is obtained.

Patentansprüche: 1. Kettenwirkmaschine zur Herstellung von ein-oder beidseitiger Schlingenware mit einer im Bereich des Auslaufens der Ware aus dem Warenabzugsystem angeordneten Rauhwalze zum Herausheben von durch Grundfäden an dem Warengrund gehaltenen Polschlingen, d a d u r c h g e k e n n z e i c h n e t, daß in der Warenabzugsrichtung hinter der Rauhwalze eine weitere aus einem Walzensystem bestehende Spannvorrichtung (7) angeordnet ist, welche mit einer größeren Umfangsgeschwindigkeit als das Warenabzugssystem antreibbar ist.Claims: 1. Warp knitting machine for the production of one or double-sided loop fabric with one in the area where the goods run out of the Goods take-off system arranged roughing roller for lifting out through ground threads The pile loops held on the ground of the goods, d u r g e k e n n z e i c h n e t that in the goods take-off direction behind the roughing roller another one from a roller system existing clamping device (7) is arranged, which with a greater peripheral speed than the goods take-off system can be driven. 2. Kettenwirkmaschine nach Anspruch 1, dadurch gekennzeichnet, daß im Bereich der ersten Walze (8) der Spannvorrichtung (7) eine zweite Rauhwalze vorgesehen ist. 2. warp knitting machine according to claim 1, characterized in that a second roughing roller is provided in the area of the first roller (8) of the clamping device (7) is. Die Erfindung betrifft eine Kettenwirkmaschine zur Herstellung von ein- oder beidseitiger Schlingenware mit einer im Bereich des Auslaufens der Ware aus dem Warenabzugssystem angeordneten Rauhwalze zum Herausheben von durch Grundfäden an dem Warengrund gehaltenen Polschlingen. The invention relates to a warp knitting machine for the production of Single or double-sided loop fabric with one in the area where the goods run out Roughing roller arranged from the goods take-off system for lifting out through ground threads pile loops held on the ground of the goods. Bei einer bekannten Maschine dieser Art (DT-OS 23 64 587) ist in der Warenabzugsrichtung hinter der Rauhwalze der Warenbaum angeordnet. Es hat sich gezeigt, daß bei dieser bekannten Maschine nicht sämtliche vorhandenen Schlingen einwandfrei erfaßt und herausgehoben werden können. In a known machine of this type (DT-OS 23 64 587) is in the goods take-off direction is arranged behind the roughing roller of the tree. It has shown that not all loops present in this known machine can be properly grasped and lifted out. Der Erfindung liegt die Aufgabe zugrunde, eine Kettenwirkmaschine der eingangs beschriebenen Art zu schaffen, welche eine sichere Aufrichtung sämtlicher Schlingen gewährleistet. The invention is based on the object of a warp knitting machine to create the type described above, which a safe erection of all Loops guaranteed. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der Warenabzugsrichtung hinter der Rauhwalze eine weitere aus einem Walzensystem bestehende Spannvorrichtung angeordnet ist, welche mit einer größeren Umfangsgeschwindigkeit als das Warenabzugssystem antreibbar ist. Durch die aus einem Walzensystem bestehende Spannvorrichtung können hohe Zugkräfte auf die Ware ausgeübt werden, die einerseits dazu dienen, die beim Herausheben der Polschlingen aus dem Warengrund frei werdende Fadenlänge gerade zu spannen und andererseits die Aufrichtung der Schlingen zu unterstützen. This object is achieved according to the invention in that in the goods take-off direction behind the rough roller another one consisting of a roller system Jig is arranged, which with a greater peripheral speed than the goods take-off system is drivable. Thanks to the clamping device consisting of a roller system, you can high tensile forces are exerted on the goods, which on the one hand serve the purpose of the Lifting the pile loops out of the fabric base, the thread length being released straight to tension and on the other hand to support the erection of the noose. Die hierfür erforderliche Spannung könnte durch den Warenbaum oder eine Spannvorrichtung in Form etwa einer gewichtsbelasteten Maschenkralle od. dgl. nicht aufgebracht werden. Die von dem Warenbaum ausgeübten Kräfte sind begrenzt, weil durch zu hohe Aufwickelkräfte eine zu starke Pressung der Polschlingen erfolgt. The voltage required for this could be through the goods tree or a tensioning device in the form of a weight-loaded mesh claw or the like. not be applied. The forces exerted by the tree are limited, because excessive winding forces result in excessive compression of the pile loops. Eine bevorzugte weitere Ausbildung der Erfindung ergibt sich aus dem Untersanspruch. A preferred further embodiment of the invention results from the subclaim. Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. Die Zeichnung zeigt die Führung der Ware zwischen Maschenbildgestelle und Warenbaum einer erfindungsgemäßen Kettenwirkmaschine. The following is an embodiment of the invention with reference to FIG Drawing explained. The drawing shows the management of the goods between mesh pattern racks and a fabric tree of a warp knitting machine according to the invention.
