Method for continuous printing of precision structures on a glass ribbon, and glass ribbon thus obtained

摘要: A method for printing a precision structure on the surface of glass strip advancing continuously at rate least 1 m/min, using an etching roller (27) applying force against to be etched, produced including protruding and recessed regions which have radii curvature, preliminary thermal conditioning (26 32) being performed upstream roller; is designed ensure temperature (J) over print thickness cooling (29) downstream controlled fixing structure; according invention making it possible determine parameters that are intimately linked obtaining particular structure, notably temperature, rate, taking into account degree creep between molding radius (R1) post-creep (R2).
