PURPOSE: To reduce a leading time considerably with an expensive device by rotating and leading a coil by means of a freely upward and downward movable snubber roller and guides on a freely travelable carriage above a drum to be mounted with the coil.

CONSTITUTION: When a coil 1 is carried by a coil car 2 into a prescribed position, a leading reel drum 34 is inserted into the coil, and the car 2 moves downward. The 1st frame 15 is moved downward, and a snubber roller 13 circumscribes the coil 1. On the other hand, the 2nd frame 21 is moved downward and a leading guide 30 and a delivery guide 32 descend. In succession, a guide 30 turns downward and a touch roller 29 and an opener 35 are pressed onto the outside circumference of the coil 1 in adequate positions. When the coil 1 is rotated counterclockwise, a leading end part 6 is led out by the cooperative operations of the three 13, 29, 35, and is led out by a required length onto the guide 30. Thereafter, a coil retainer 18 descends to hold down the end part 6, and the car 2 ascends. The drum 34 and a carriage 28 are run synchronously to carry the coil 1 into the drum of an uncoiler.
