WRAP TOOL FOR MAGNETIC FIELD-RESPONSIVE HEAT-FUSIBLE PIPE COUPLINGS
摘要
A wrap tool having first and second coil regions and flange regions for inducing oscillating magnetic fields to fuse a plastic coupling having heating elements to a substrate. The first and second coil regions are wrapped around a selected plastic coupling and substrate to induce fusion currents causing melting and fusion of plastic pipes inserted into a magnetically energizable pipe coupling. The flange regions of the wrap tool are positioned adjacent each other overlappingly or inner surface to inner surface, permitting opposite current coil portions to cancel the other's magnetic fields and reduce coil inductance.
