ABSTRACT:
The present invention is an inductive sealing unit, which includes a conductive coil assembly that has at least two sections. At least one of the sections is adjustable with respect to the other. Each section has a magnetic flux concentrator, such as a ferrite core. A flexible conductive coil, such as litz wire, is disposed with respect to the magnetic flux concentrator to provide an electromagnetic field which induces heat sufficient to seal an object. The assembly can be adjusted to accommodate different size objects to be sealed.
