Abstract
A flanged, dish shaped rectangular pressure responsive diaphragm is made from non-stretchable flat sheet stock in which the corners are formed with a tapering loop of excess material, and pleat folds take up the excess flange material to allow a tab portion to lie flat across the corner. Spacer strips and pieces are added to provide a uniform flange thickness.
