<p>There is disclosed a roller guide device for guiding elongate rolling material (3) to a pair of rolls (9a, 9b) of a rolling mill and comprising a first pair of lateral guide rollers (10a, 10b) which are arranged adjacent to the entry to the rolls (9a, 9b) and which rotate about substantially vertical axes, and a second pair of longitudinal rollers (14a, 14b) which are arranged upstream of, but close to the first pair of rollers (10a, 10b) and which rotate about substantially horizontal axes. The two pairs of guide rollers define a guide path (23) to the rolling mill, and are mounted on a housing (7) which is carried in cantilever manner by a base (32) of the guide device which is mounted on a rest bar (37) of the rolling mill. The first pair of lateral rollers (10a, 10b) are mounted on the ends of spring-loaded levers which resiliently resist movement of the rollers in a direction away from the guide path (23), whereas the second pair of longitudinal rollers (14a, 14b) are mounted on fixed portions (15, 16) of the housing (7) via eccentric roller pins (17a, 17b) which are angularly adjustable in order to vary the clearance between the longitudinal rollers (14a, 14b).</p> |
