ABSTRACT:
A paper spring is formed by longitudinally folding a sheet along parallel fold lines to provide a strip and thence transversely folding the strip in a zigzag manner. The resulting paper spring may be contained in a paper housing in the form of an open-sided rectangular band and a series of the resulting paper spring units may be mounted on a cardboard panel to provide a platen. Such springs or units provide a resilient cushion for fragile items shipped in boxes.
