Abstract

A carrier device for at least two twister or bobbin tubes (4, 17) disposed axially one above the other, comprising a substantially sleeve-shaped carrier member whose bottom end has a radially outwardly directed support surface (3) for supporting the lower tube (4). Disposed in the central region of the carrier member is a support surface (12) whose circumference is smaller than the inner circumference of the lower tube (4) to enable the latter tube (4) to be slipped onto the carrier body over the support surface 12. An annular or disc-shaped pull-off aid (13), which is preferably mounted so as to be freely rotatable, is slipped onto the support surface (12) and ensures that the threads from the tubes are not damaged when they are drawn off overhead, and that excessive stressing of the threads is avoided.
