PURPOSE: To draw out plural long size materials rapidly simultaneously, by connecting restricting claws to hit to the peripheral surface of the long size material, to clamp arms respectively through spherical bearings, in the posture to cross their axes to the long size material, and engraving V-shaped grooves the peripheral surface of the long size material is fitted, to the restricting claws.

CONSTITUTION: A clamp unit 5 which can grasp the upper end of a long size material is provided, and the clamp unit 5 has a pair of clamp arms 7 which can open and close into a posture to hold the peripheral surface of the long size material. To each clamp arm 7, restricting claws 9 to hit to the peripheral surface of the long size material are connected through spherical bearings 8 whose axes are crossed to the long size material, and about V-shaped grooves 9a and 9b to which the peripheral surface of the long size material is fitted are engraved to each resricting claw 9. Consequently, plural long size materials can be drawn out rapidly simultaneously.
