摘要: An apparatus for securing a binder to the spine of a cover with rivets. A pair of rivet supports holding two rivets in a support position over a pair of anvils is movable between release and support positions with a biasing spring returning the rivet support to the release position. A drive shaft moves the pair of rivets in a downward vertical direction terminating in a downward stroke so as to drive the plain ends of the rivets through the cover spine and the binder. Drive linkage connected to a horizontal rotatable drive bar activated by a lever activates the drive shafts to a limited lowered position and a raised position. The anvils receive the plain ends of the rivets and make the plain ends of the rivets into second heads upon termination of the downward stroke of the drive shafts whereby the rivets secure the binder and the cover spine. Keepers prevent lateral and transverse movement of the binder and and cover.
