Zusammenfassung:	FIELD: rolling of especially thin-wall tubes of hard-to-form materials in working stand of roller type cold rolling mill. ^ SUBSTANCE: working stand includes movable housing with supporting beams; movable cartridge with four rollers on journals engaged with supporting beams of movable housing; common leverage reciprocation motion drive of housing and cartridge. Width of one pair of rollers exceeds that second pair of rollers by value providing shifting of roller butt relative to zone of biting blank. Relation of diameters of one pair to diameter of journals of other pair of rollers is equal to relation of roller rolling diameters. ^ EFFECT: possibility for rolling high quality square shapes with uniform thickness of wall without burrs on tube surface. ^ 4 dwg
