Abstract (en)

[origin: DE19947547A1] Spinning rotor has surfaces with a coating in contact with the fibers and thread. The coating consists of an intermediate layer (9) which is free from hard material between two hard material-containing layers (7, 10).

Abstract (de)

Ein Spinnrotor für eine Offenend-Spinnmaschine weist eine auf die Oberfläche des Grundmaterials (12) aufgebrachte Beschichtung aus einem Nicht-Eisen-Metall mit darin eingebetteten Hartstoffkörnern, insbesondere einer Nickelschicht mit Diamantkörnern, auf, wobei die Beschichtung aus mindestens zwei hartstoffkörnerhaltigen Schichten (7, 10) steht und zwischen den hartstoffkörnerhaltigen Schichten (7, 10) jeweils eine hartstoffkörnerfreie Zwischenschicht (9) vorhanden ist. Bei einem stellenweisen Ablösen der Verschleißschutzschicht, wie es durch den Schaber beim Reinigen des Spinnrotors verursacht werden kann, bleiben Verschleißschutz und Spinneigenschaften an den beschädigten Stellen des Spinnrotors erhalten. Dadurch kann eine erhebliche Verkürzung der Standzeit des Spinnrotors vermieden werden. <IMAGE>
