ABSTRACT:
Pallet nails are subjected to induction heating to char the wood therearound. A pair of induction coils are brought into engagement with the frame pieces of the pallet and with the boards nailed to the frame pieces such as to place the nails within the eddy currents of the electric radio frequency field surrounding the coils. The nails become red hot instantaneously and within a matter of a few seconds the wood is so fully charred along the nails that they either fall from place or can be easily and quickly removed from the soft, highly porous charred substances.
