Electrolysis apparatus having liquid squeezer out of contact with strip

In an electrolytic apparatus that passes a strip between paired members of a liquid throttle unit provided on at least one of an inlet side and an outlet side of a treatment cell through which the strip is continuously passed, an electrolytic apparatus with strip non-contacting liquid throttle unit is provided which is characterized in that the spacing between the paired members of the liquid throttle unit is set very slightly larger than the thickness of the passed strip to maintain the surfaces of the strip and the liquid throttle unit members, e.g. a seal roll, nozzle device or wedge-shaped block, in a non-contacting state.
