ABSTRACT:
A binding comb shaping device for producing profile-bent binding combs for comb binding of sheet layers has rotary bending tools with bending sliding edges and/or in the form of rolling members, which, between advance cycles of the binding comb blank, move past shaping edges of shaping anvils in arcuate paths and thereby in a substantially vibration-free manner and at high working speeds give the binding comb blank its profile shape.
