Abstract

Eine Zungennadel für maschenbildende Textilmaschinen weist ein in dem Zungenschlitz (6) des Nadelschaftes angeordnetes Federelement (15) auf. Das in dem Zungenschlitz (6) liegende Endteil (10) des Nadelzungenschaftes (9) ist als Nockenelement mit einer gekrümmten Nockenfläche (18) ausgebildet, deren radialer Abstand von der Schwenkachse (12) der Nadelzunge (8) von der Zungenschaftoberseite (16) zur Zungenschaftunterseite (21) hin stetig abnimmt.

A latch needle for stitch-forming textile machines has a spring element (15) arranged in the latch slot (6) of the needle shaft. The end part (10) of the needle tongue shaft (9) lying in the tongue slot (6) is designed as a cam element with a curved cam surface (18) whose radial distance from the pivot axis (12) of the needle tongue (8) from the tongue shaft top (16) to Tongue shaft underside (21) steadily decreases.
