High speed laying head

摘要

A rolling mill laying head has a quill (14) supported for rotation about its longitudinal axis (X) between axially spaced first and second bearing assemblies (16,18). A laying pipe (24) is carried by the quill for rotation therewith. The laying pipe has an entry section (24a) lying on the quill axis between the first and second bearing assemblies, and a curved intermediate section (24b) extending through and beyond the second bearing assembly to terminate at a delivery end (24c) spaced radially from the quill axis to define a circular path of travel. The dimension (A) by which the laying pipe extends beyond the second bearing assembly is less than the diameter (D) of the circular path.
