Title:
COIL PRODUCTION DEVICE AND COIL PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/167179
Kind Code:
A1
Abstract:
This coil production device (100) comprises an adjustment mechanism (50) for adjusting the intervals among a plurality of wire materials (2) headed toward a winding core (25) and a heating device (60) for bonding the plurality of wire materials (2) wound around the winding core (25). The adjustment mechanism (50) comprises a lever (52) rotatable around a rotation center axis that is parallel to the winding core (25) axis, and, provided on the lever (52), a plurality of rollers (53) aligned in one row with a predetermined interval therebetween and having respectively wound therearound the plurality of wire materials (2) headed toward the winding core (25). The lever (52) is constituted so as to be rotatable between a first position wherein the wire materials (2) headed from the roller (53) to the winding core (25) are relatively close to one another and a second position wherein the wire materials (2) headed from the rollers (53) to the winding core (25) are relatively distant from one another.
