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