FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to tube feed and turn at cold rolling mills. Proposed method comprises feeding tube billet and rolled tube for required feed setting fulfillment increment and synchronous turn of billet and mandrel rod through equal preset angle of required turn setting fulfillment, and turning rolled tube and mandrel. Note here that rolled tube turn angle is smaller than preset of billet and mandrel rod required turn setting fulfillment angle.
EFFECT: minimised probability of mandrel screwing off its rod.
