Friction between the leaves as they flex has a damping effect. I have always assumed that binding springs with cord was done to increase the damping effect.
Daimler springs were a beautiful pieces of engineering. There is a spacer between each leaf at the fixing point to keep the leaves apart. At the end of each leaf thear is a phosphor bronze 'top hat' section spacer. The 'brim' of the hat is the same thicknes as the spacer at the fixing point. The crown of the hat goes through a hole in the leaf above. It means there is no steel to steel contact between the leaves and each leaf acts independently. Thats what you got for paying £1,500 for a chassis with no bodywork in 1934. That would have bought you several houses!
