Description

TECHNICAL FIELD

[0001] The invention relates to a roller guide for guiding stock in a longitudinal feeding direction toward a pair of rolls for shaping the stock according to the preamble of claim 1 and to a method for guiding stock according to the independent method claim. In particular, the invention relates to a roller guide and to a method for use in the production of wire, rods and beams.BACKGROUND AND PRIOR ART

[0002] Roller guides are commonly used for guiding hot stock, such as wire stock or rod stock, in rolling mills. Primarily, roller guides are placed before a pair of rolls used to shape the stock, so called entry roller guides. These roller guides guide the stock which is to be rolled toward a particular rolling groove. The use of roller guides reduces the risk of damaging the stock upon entry between the pair of rolls and enables feeding the stock at high feeding rates.

[0003] U.S. Pat. No. 3,935,722 discloses a roller guide for guiding stock toward a pair of rolls. The rol...
