Abstract
Die Erfindung betrifft eine Auflöseeinrichtung für Textilmaschinen, insbesondere für Spinnmaschinen bzw. Offenend-Spinnmaschinen, mit einer Auflösewalze an deren Außenumfang eine Vielzahl von Zähnen (2) angeordnet ist. Die erfindungsgemäße Auflöseeinrichtung zeichnet sich dadurch aus, daß die Zähne (2) mit einem Zahnabstand (LZ) von höchstens 20 mm, vorzugsweise von unter 12 mm, angeordnet sind und mindestens aus zwei Abschnitten bestehen, wobei ein erster an einer Zahnspitze (5) liegender Abschnitt einen positiven oder zumindest senkrechten Brustwinkel (WB) aufweist und ein zweiter Abschnitt eine in Bewegungsrichtung (3) der Garnitur abfallenden Schräge (8) ist, und daß der Abstand zwischen der Zahnspitze (5) und einem Berührungspunkt einer vertikalen Tangente (10) am Übergangsbereich zwischen dem ersten und dem zweiten Abschnitt eine technologisch wirksame Zahnhöhe (Ht) bildet, wobei das Verhältnis von technologisch wirksamer Zahnhöhe zu Zahnabstand höchstens 1 beträgt. The invention relates to an opening device for textile machines, in particular for spinning machines or open-end spinning machines, with an opening roller on the outer circumference of a plurality of teeth (2) is arranged. The opening device according to the invention is characterized in that the teeth (2) with a tooth spacing (LZ) of at most 20 mm, preferably of less than 12 mm, are arranged and at least consist of two sections, wherein a first on a tooth tip (5) lying Section has a positive or at least vertical breast angle (WB) and a second portion in the direction of movement (3) of the clothing sloping slope (8), and that the distance between the tooth tip (5) and a contact point of a vertical tangent (10) Transition region between the first and the second section forms a technologically effective tooth height (Ht), wherein the ratio of technologically effective tooth height to tooth spacing is at most 1.
