    (54) Manufacturing system for a flexible coil construction


    (57) Method for manufacturing a flexible coil construction which can form part of an electronic circuit as an electromagnetic antenna. In this flexible coil construction, the insulated wire for the turns of the coil is provided with a coating which has the property that no bond develops at commonly prevailing ambient temperatures. A second property is that in a first increased temperature range adhesion does occur and a third property is that in a second, still higher temperature range the adhesive and bonding properties disappear substantially through an irreversible structure change and do not return upon cooling.
