A centrifugal pot spinning process for spinning yarn of classical character is provided in which either in one stage a fully twisted yarn or in a first stage a partially twisted yarn is spun in a centrifuge (6) and removed from it and, in the case of the partially twisted yarn, the remaining twist is imparted to the yarn in a second stage upon removal while being wound up. A centrifuge (6), a drawing frame (1), a piecing mechanism (2), and a traversing thread guide tube (4) are used. The centrifuge (6) rotates in a space (7) under reduced pressure (pu). Normal air pressure (pn) prevails inside the centrifuge (6) and spinning is carried out under normal air pressure (pn) inside the centrifuge. The reduced pressure (pu) is adjusted in such a way that, during rotation of the centrifuge (6), essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge (6, 35, 45, 53) against the housing (5') is largely suppressed. A vacuum centrifuge (5) is positioned so as to pivot inside the housing (5'). The space (7) between the centrifuge (6) and the housing (5') can be placed under variable reduced pressure (pu). The reduced pressure is adjustable in such a way that, during rotation, essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge is largely suppressed.
