ABSTRACT:
A hydraulically inflatable roll for flat rolled products is formed with a constant cross section internal fluid channel spaced uniformly from its working surface and extending spirally from end to end of the roll. The channel is connected through an end of the roll to a source of hydraulic fluid under pressure and also to a pressure transducer which in turn is connected to a display device. A proximity trigger is associated with an end of the roll so as to signal the start and the end of the circumferential travel of the channel past the contact line between roll and work when the roll is rotated, and the pressure exerted on that moving area in that interval is continuously measured and transmitted to the display device. Means are also disclosed for using that signal to control gauge and shape of the rolled product.
