International ClassC25B 9/00 (20060101)AbstractA 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.Field of SearchElements |
