Description
gnetplattenlosen Bereich wieder in den zugeordneten Aufnahmerauni 5 zurück, während bei erhöhter Umlaufgeschwindigkeit der WickelweHe der Sperrkörper 6 den magnetplattenfreien Raum C aufgrund der Fliehkraft überbrückt und an den Anschlag 9 kommt und nunmehr im Zusammenwirken mit dem zugeordneten Sperrzahn 12 eine Verriegelungswirkung herbeiführtThe area without the gnet plate back into the associated receiving hall 5, while at increased rotational speed of the winding path the locking body 6 bridges the space C free of magnetic plates due to the centrifugal force and comes to the stop 9 and now brings about a locking effect in cooperation with the associated locking tooth 12
