METHOD AND APPARATUS FOR TEMPORARY ARRESTING OF ELONGATED PRODUCTS PASSING BETWEEN PASSES ARRANGED UPSTREAM AND DOWNSTREAM IN ROLLING MILL Russian patent published in 2006 - IPC B21B1/26 

FIELD: production of rolled elongated products.

SUBSTANCE: method comprises step of feeding product passing along pass arranged upstream onto cylindrical drum; rotating said drum in one direction for coiling and accumulating product on it in the form of large number of turns; reversing direction of drum rotation for uncoiling product; feeding uncoiled product to pass arranged downstream. According to invention product is coiled and uncoiled in respective places of drum mutually spaced along its circumference and arranged in the same horizontal level; reciprocating drum at process of its rotation in axial direction normal to said horizontal level. Apparatus includes cylindrical drum mounted between passes; unit for feeding product on drum and for feeding uncoiled product to pass arranged downstream; drive unit for rotating drum in one direction in order to accumulate product in the form of large numbers of turns and for reversing drum rotation sign in order to uncoil product. According to invention drum is made with possibility of coiling and uncoiling product in respective places of drum mutually spaced along drum circumference and arranged in the same horizontal level. Apparatus also includes unit for reciprocating drum rotating for coiling and uncoiling product in axial direction normal to said horizontal level.

EFFECT: enhanced efficiency of rolling mill due to possibility for rolling articles of less size at keeping minimum rolling speed values.
