DEVICE FOR MOVING STRIP TENSIONING Russian patent published in 2009 - IPC B21B39/08 

FIELD: metallurgy.

SUBSTANCE: invention relates to rolling equipment, particularly to the equipment intended for channeled sheets production. The device is placed before profile-bending mill and includes serial installation of four tension roller in the profiling direction. The rollers are implemented together with bodies of the given diametre D=(130…150)h, mm, where h is a maximum thickness of the strip, mm. Two intermediate rollers are implemented so that they can move vertically and rotate horizontally clockwise and counterclockwise to 3°…4° angle and around the points being in the circle centers of the similar end surfaces of roller bodies. The horizontal distance between intermediate rollers is D+(50…60) mm.

EFFECT: invention provides for improving quality of profiles due to their geometry improvement.
