Abstract
A binder assembly having a backing, which may be the spine or cover, with a prong-carrying plate or plates secured to the backing by means of the prongs. Upstanding rivets secure a support means to the plates. The support means may support a ring binder mechanism, a binder clamp mechanism or other binder mechanism. The support means is secured to the assembly by deforming the heads of the rivets. The rivets and plates may be secured together by assembly and swaging. Spacer elements may be positioned between the plate or plates and the arcuate casing of a ring binder mechanism.
