FIELD: plastic working of metals, namely production of shaped tubes.
SUBSTANCE: guiding apparatus is mounted in front of first stand of tube forming mill and it includes driven feeding rollers. In addition guiding apparatus includes pickup for detecting position of welded seam in vertical plane. Said pickup is functionally coupled with rack unit for rotating tube in said vertical plane by angle 0 - 45°. It is possible to use magneto-electric structure-scope as said pickup. Rack unit includes two driven gummed racks moving in horizontal plane in mutually opposite directions. Invention provides possibility for automatic guiding of tube blanks to first shaping stand of tube shaping mill in position preventing presence of welded seam in corner of four-roll grooved pass and therefore eliminating its breakage.
EFFECT: lowered production expenses for making square and rectangular tubes.
