ABSTRACT:
The present invention relates to a roll assembly comprising grooved rolls. A neck of each roll is provided with a thrust shoulder placed in a thrust hydrostatic bearing mounted in a chock secured to a housing. The bearing comprises thrust disks each arranged on both end faces of the shoulders substantially parallel thereto. The sides of the disks facing the ends of each shoulder are fitted with hydrostatic pockets communicating with a fluid source. The fluid source, designed for adjustable delivery of fluid, communicates with the hydrostatic pockets of one of the thrust disks of a roll and of the other thrust disk facing it. There is another fluid source with adjustable delivery of fluid communicating with the hydrostatic pockets of the other thrust disks. This enables, by varying the deliveries of the fluid sources, the mutual disposition of the shoulders to be adjusted relative to the thrust disks and thereby permits control over the mutual arrangement of the rolls directly in the course of rolling.
