A power operated belt splicing system is provided. In one form, staples are driven through a belt and clinched in a final set using a power driven tool and a force applying member having multiple drive punches. A lower force applying end on a punch preferably has a first portion to drive the staple and a second portion to drive a leading edge of the belt fastener against the belt thereby distributing the drive force over both the staple and the belt fastener. Preferably, the second surface is shaped similarily to the outboard edge of the upper plate. A pair of adjacent punches can substantially simultaneously drive two pairs of preset staples with each pair of preset staples being associated with one of a pair of adjacent hinged belt fasteners thereby attaching a pair of belt fasteners to a belt in a single operation. The initial and final staple set may be done with the same power tool.
