SEGMENTED RING GUIDE FOR ROLLING MILL LAYING HEAD

摘要

A laying has a quill (12) rotatable about an axis (x), and a pipe (14) carried on the quill (14). The pipe (14) has an entry end (14a) arranged to receive a product, and an intermediate portion (14b) defining a curved guide path leading from the entry (14a) and to a delivery end (14c) spaced radially from the quill axis (x) and from which the product is discharged as a helical series of rings. A guide defines a helical extension of the guide path, and comprises a helical support plate (22) projecting outwardly from the quill (12). A plurality of channel-shaped guide sections (20) supported end to end on the support plate (22). The guide sections (20) form a segmented radially outwardly facing helical trough (16) to surrounded by a cylindrical shroud (18) that cooperates with the guide sections (20) to definee radially and axially confined helical extension of the guide path.
