FIELD: manufacture of sheet material, wire.
SUBSTANCE: rolling mill laying head (22) comprises quill (24) rotatable about central axis (X), said quill (24) being equipped with guide pathway (26) configured and arranged to transform a longitudinally moving product into a continuous series of rings, stationary support structure (28) and axially spaced radial bearings (30, 32) supporting said quill (24) for rotation about said axis (X). Reduction of instability of the device associated with the beating effect is provided by the fact that one of said bearings (32) comprises a hydrostatic oil film bearing, having an internal diameter of at least about 500 mm, and having a ratio of the length of the bearing to its diameter D less than 0.25.
EFFECT: invention relates to wire rolling.
