Abstract

PURPOSE:To prevent the bending of a blade as well as to accomplish a high speed performance of work by a method wherein a protective blade is provided on each blade, a plurality of spools corresponding to the coil diameter are provided and the coil is wound on the spools, starting from the coil of a small diameter in such manner that the blade and a spool are protruded successively. CONSTITUTION:In the device where the coil is directly wound on the blade 2 and is inserted in a core in that state of condition, the protective blade 12 is provided on each blade 2 in such manner that the blade 2 can be slided upwards independently from other blades. On the exterior of the blade 2, a plurality of spools 21-23 are provided in such manner that they can be slided upwards independently from other spools. A winding work is first performed on the coil of a small diameter by elevating the blade 2 and the spool 21 corresponding to the coil of the small diameter, then a medium diameter coil is wound by elevating the blade and the spool 22 corresponding to the medium diameter coil and lastly a large diameter coil is wound using the spool 23.
