Title:
AIR CORE COIL WIRE WINDING TOOL AND AIR CORE COIL PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/199893
Kind Code:
A1
Abstract:
The purpose of the present invention is to allow a coil to be removed readily from an air core coil wire winding tool when producing an air core coil.
This air core coil wire winding tool has a winding core which is configured by bringing into contact with one another individual winding core configuration pieces 4, 5 resulting from the division of a winding core 3 by two-way splitting. In the air core coil wire winding tool, each of the winding core constituent pieces to be brought into contact with one another has a surface provided with an incline 19 for converting a force squeezing the winding core, which is exerted by a coil wire 18, into forces in the respective directions in which the winding core constituent pieces are to be pulled out.
