Abstract

Der Bringergreifer (1) einer Greiferwebmaschine mit ortsfestem Fadenvorrat, mit einer Klemmzunge (4) im Greifergehäuse (2) und mit einem Zusatzklemmelement (7) auf einer Breitseite der Klemmzunge (4) ist so gestaltet, dass das Zusatzklemmelement im Bereich seiner Klemmzone für den Schussfaden teilweise auf der Unterseite (22) des Greifergehäuses aufliegt. Es ist im Einlauf- und Klemmbe­ reich des Fadens (9) als schlanke, ebene, der Krümmung der bekannten Klemmzunge (4) folgende Blattfeder ausge­ bildet und auf der einen Seite mittels der Verschraubung (8) an der Klemmzunge (4) befestigt, während es unter Eigenvorspannung am anderen Ende etwa im mittleren Bereich gegen die Klemmfläche (22) des Greifergehäuses drückt. Wenn die Klemmzunge (4) mittels der Lasche (42) im vorderen Teil vom Greifergehäuse wegbewegt wird, hebt gleichzeitig das Zusatzklemmelement (7) von der Zusatz­ klemmfläche (22) ab, wodurch Verunreinigungen zwischen den jeweiligen Klemmflächen an der Klemmzunge (4), dem Zusatzklemmelement (7) und dem Greifergehäuse (22) abfallen bzw. abgesaugt werden können. The rapier rapier (1) with a rapier weaving machine stationary thread supply, with a clamping tongue (4) in the Gripper housing (2) and with an additional clamping element (7) on a broad side of the clamping tongue (4) is designed that the additional clamping element in the area of its clamping zone for the weft partially on the underside (22) of the Gripper housing rests. It is in the inlet and clamp realm of thread (9) as slim, flat, of curvature the known clamping tongue (4) following leaf spring out forms and on one side by means of the screw connection (8) attached to the clamping tongue (4) while it is under Self-tensioning at the other end in the middle Area against the clamping surface (22) of the gripper housing presses. If the clamping tongue (4) by means of the tab (42) in the front part is moved away from the gripper housing at the same time the additional clamping element (7) from the additive clamping surface (22), causing contamination between the respective clamping surfaces on the clamping tongue (4), the Additional clamping element (7) and the gripper housing (22) fall off or can be suctioned off.
