Abstract (en)

The centrifugal spinning machine has at least one spinning station (10), each with a rotating spinning pot (14), a guide (18) to lead in the roving (26') feed, and a drive (38) to give an axial movement between the roving guide (18) and the spinning pot (14). The roving yarn (26) at the guide (18) passes through the rotary axis of a rotor (46) of the drive (38). The drive is an electromotor, with a direct working action between the rotor (46) and the guide (18), where the rotor (46) is a cylinder (48) which holds the guide (18) in a positive fit. The cylinder (48) has an inner threading (50) which meshes with the outer threading (52) round the guide (18). The electromotor is a step motor (40). The guide (18) has an axial movement, keyed (58) against rotation in its mounting at the drive (38). The drive (38) has a shrouding (54) to prevent the entry of fiber debris and the like, as a flexible cylindrical cover (56), which grips at least partially round the guide (18). An Independent claim is included for a centrifugal spinning process where the roving yarn through the guide passes through the drive rotor axis, and the guide is moved axially by a direct action of the drive on it.

Abstract (de)

Die Erfindung betrifft eine Zentrifugenspinnmaschine mit wenigstens einer Spinnstelle (10), die jeweils einen in Rotation versetzbaren Spinntopf (14), einen mit Vorgarn (26') beschickbaren Fadenführer (18) sowie eine Antriebseinrichtung (38) zum Erzeugen einer Axialbewegung zwischen Fadenführer (18) und Spinntopf (14) aufweist. Erfindungsgemäß ist dabei vorgesehen, daß der im Fadenführer (18) geführte Faden (26) durch die Drehachse eines Rotors (46) der Antriebseinrichtung (38) läuft. <IMAGE>
