Abstract (en)
[origin: WO2014042926A1] A laying head for forming an axially moving hot rolled product into a helical series of rings comprises a quill rotatable about an axis, with a tubular body journalled for rotation between axially spaced bearings, and a nose (36)projecting axially and forwardly from its tubular body. A product guide is carried by the quill. The product guide is configured to form the product into a helical series of rings. A guide trough (50) provides a helical extension of the product guide. Major portions of the product guide and the guide trough are carried on a continuous helical support (42) on the nose of the quill. The guide trough is channel shaped, with a continuous bottom defining the rim of the helical support, and with segmented detachable side walls.
