Abstract
A method and apparatus for installing a sheet membrane in an electrolysis cell is disclosed. In the procedure, a rectangular sheet is first soaked in a selected wetting liquid preliminary to installation, one edge of the rectangular sheet is grasped in a lengthwise rigid releasable clamp, that edge is then positioned through a slot to extend the sheet member from a transport cylinder whereupon the sheet is rolled around the cylinder. This leaves an exposed marginal edge on the sheet which is clamped in a second and similar clamp. This then enables the sheet to be transported and positioned above a slot where the sheet is unrolled and positioned through the slot into an electrolysis cell. Suitable apparatus is also disclosed.
Claims4
Apparatus for installing a rectangular sheet membrane in an electrolysis cell formed of facing halves openable to define slot in the cell, comprising:
- (a) first and second similar marginal releasable clamps fastenable to a sheet membrane at opposing edges, each of said clamps including adjustable lock means on said clamps to releasably lock said clamps;
- (b) axially hollow elongate transport spool means having a lengthwise slot sized to receive one of said clamps axially therein while holding the sheet in the slot to thereby anchor one edge of the sheet membrane, and further enabling the sheet membrane to be rolled around said spool means exposing a second marginal edge parallel to said spool means and wherein said remaining clamp is enabled to be releasably clamped on the second and exposed marginal edge of the sheet membrane.
