Abstract: According to an aspect of the present disclosure, an adjustable induction foil sealing device is used to hermetically seal a container. The device can be adjusted to accommodate differently sized containers. The device includes a power supply cabinet, first and second rail assemblies and an adjustment assembly coupling the rail assemblies together and coupling the rail assemblies to the cabinet. Each rail assembly has an induction sealing coil and conductive contacts. The contacts on the rail assemblies are in electrical contact with the contacts on the cabinet. The adjustment assembly is configured to adjust the relative positions of the rail assemblies relative to each other and relative to the cabinet, while maintaining the electrical connection of the contacts.
