Abstract

A yarn head rotor 1 for a cabling machine, comprising several deflection rollers 2 for evening the yarn tension of two yarns being twisted, each deflection roller being rotatably mounted on a pivot axis 5 at right angles to the rotor axis of the yarn head rotor 1 and guided across the two yarns. The deflection roller 2 is mounted in the yarn head rotor 1 by bearings 6 at both ends of the deflection roller 2, wherein the two ball bearings 6 are each enclosed by a housing 7 of the yarn head rotor 1, which is closed with a cover 8, and yarn guiding eyelets 9, guiding the inner and outer yarns 17, are arranged upstream of the deflection roller 2 in such a way that they supply both yarns of the deflection roller between the two ball bearings 6 to the yarn head rotor 1.

Dependent claims

Yarn head rotor (1) for a cabling machine, comprising several deflection rollers (2) for evening out the yarn tension of two yarns to be twisted, each of the deflection rollers (2) being rotatably mounted on a pivot axis (5) arranged at right angles to the rotor axis of the yarn head rotor (1) and over which the two yarns are guided,

characterized in that,
at least one deflection roller (2) is mounted in the yarn head rotor (1) by bearings (6) at both ends of the at least one deflection roller (2), that the two bearings (6) are each enclosed by a housing (7) of the yarn head rotor (1), which is closed with a cover (8), and that yarn guiding eyelets (9), guiding the inner and outer yarns (17), are arranged upstream of the at least one deflection roller (2) in such a way that they supply both yarns to the at least one deflection roller (2) between the two bearings (6) of the yarn head rotor (1).

Dependencies are inferred from the claim text.
