Abstract

Bei einem frei umlaufenden Greifer (4) für Doppelsteppstichnähmaschinen, der eine mit einem Anhaltefinger (11) versehene Spulenkapsel (8) aufweist, ist an der Umfangsseite der Spulenkapsel (8) in der Nähe des Anhaltefingers (11) ein radial abstehendes Schleifenablenkelement (13, 14) angeordnet. Durch das Schleifenablenkelement (13, 14) wird eine durch das mitunter nicht zu vermeidende Einstechen der Nadel (1) in das Nadelfadenende entstehende Abstichschlinge AS zwangsläufig auf die Stirnseite der Spulenkapsel (8) abgelenkt und dadurch ein Blockieren des Greifers (4) verhindert.
