I work at a cable/wire manufacturing plant. We run everything from 14 AWG up to 4 aught solid and stranded wire through a nylon or metal die with a planer blade bolted to the top . We can strip thousands of meters a day this way. Granted this uses large let offs and motorized take ups but something similar could be used on smaller scale operations. The smaller guages can be pulled and stripped by hand, particularly the solid conductors.
