UNWINDING METHOD FOR LEVEL-WOUND COIL

摘要

This aims to provide a level-wound coil unwinding method capable of letting off a tube stably in a remarkably easy manner while avoiding the rise in the cost as much as possible. A level-wound coil (LWC) (10) is arranged to have its axis in the vertical direction, and a tube (2) is extracted through a drawing curved guide tube (12) arranged thereover, so that the LWC (10) is unwound from the outer side. A guide pipe (20) having a flexible pipe portion (22) is constituted such that the guide pipe (20) is not fixed but armors the tube (2) so that its lower end may be positioned close to a point (P) for letting the tube (2) off the LWC (10), and such that the guide pipe (20) can move freely in the tube axis direction by its own weight at the time of extracting the tube (2). The tube (2) is let off in the mode where its lower end is always close to the tube let-off point (P).
