Abstract

A two-for-one twisting or cabling spindle apparatus (1) with a supply bobbin (4) mounted on a pot base (2) of a stationary protective pot (3) and a spindle (6) arranged below the protective pot (3) to guide a yarn (5) to be processed during a twisting or cabling process. The spindle (6) is rotatably mounted by a lower bearing device (7) in a bearing housing (9) fixed on a spindle rail (8) and an upper bearing device (11) mounted to the stationary protective pot (3). The largest diameter (d) of the rotatably mounted spindle (6) is at least 10% less than the diameter (D) of a touching line (23) of the pot base (2) of the stationary protective pot (3) with the yarn (5).
