Abstract

The binding assembly depicted in the drawings includes a pair of reinforcing strips 10 and 12 positioned on opposed sides of stacks 14 in a common marginal region thereof. Reinforcing strips 10 and 12 each have a plurality of spaced recessed portions or slots 16 therein. Fasteners 18 are driven through reinforcing strips 10 and 12 with the extended portions or legs 20 thereof passing through stack 14. Fasteners 18 are substantially U-shaped being formed from a substantially cylindrical or retangular wire. Back portion 22 connects legs 20 to one another. The depth of recessed portion 16 is sub-stantially equal to the diameter or thickness of the wire of fasteners 18. In this manner, the upper surface of back portion 22 is substantially flush with the upper surface of reinforcing strip 10. No portion of fastener 18 extends above reinforcing strip 10 after the former has been driven through stack 14.
