Abstract
An induction foil cap sealer includes a sealing head module and power supply module that can be separately mounted and replaced. Both modules are convection air-cooled without a requirement for forced air-cooling or water cooling.
Claims5
A method of sealing a foil cap to the opening of a container comprising the following steps:
- providing a sealing head assembly having an air-cooled inductor disposed adjacent to a magnetic flux concentrator;
- providing an ac current to the air-cooled inductor from a power supply located remotely from the sealing head assembly to generate a magnetic field in the air-cooled inductor, the magnetic field creating heat primarily in the non-water cooled, air-cooled inductor and the magnetic flux concentrator;
- and
- transferring the heat from the sealing head assembly by a non-forced air convection means.
