ABSTRACT:
A tentering apparatus for tensioning a sheet-like member, for example, a membrane used in an electrolyzer. The tentering apparatus includes four clamping assemblies arranged in a picture frame shape configuration adapted for clamping at least a portion of its periphery of a sheet-like member. One pair of clamping assemblies have studs at each end rotatably mounted at the ends of the second pair of clamping assemblies. A planar sheet-like member is tensioned by clamping the periphery of the sheet-like member and applying a pulling force generally outwardly and normal to the second pair of clamping assemblies and rotating the first pair of clamping assemblies to cause a pulling force generally normal to the first pair of clamping assemblies.
