INDUCTION HEATING COIL

摘要

This invention relates to a split return induction coil and in particular to a coil which is suitable for drying sealant deposited on can ends. Thus a conveyor (15) carried end caps (10) in an edge-to-edge configuration beneath a split return coil (16) which is fed from an R.F. source (17). The coil (16) has a central portion (18), which carries the full current (I), and two side return portions (19), which carry half the current. The central portion (18) has a non-linear section (20).
