A perfect binder wherein the grippers of a transporting unit advance discrete stacks of paper sheets along a horizontal path past a series of successive treating stations from a stack receiving location of the grippers are located in a common plane, and those portions of the stacks which require treatment extend downward beyond the respective undersides. A second unit of the perfect binder includes a set of treating devices (which can include aligning panels, milling tools, grinding tools, adhesive applicators and cover applicators) which are mounted on a platform beneath the path for the stacks and are individually adjustable toward or away from the common plane. In addition, the perfect binder is provided with an apparatus which can move the transporting unit and/or the second unit toward or away from the other unit in order to simultaneously alter the spacing of all treating devices relative to the common plane.
A perfect binder wherein stacks of sheets are bonded to covers by means of an adhesive, comprising a first unit having means for transporting a series of stacks along a predetermined path in a predetermined direction past a plurality of successive treating stations from a receiving to a withdrawing location, said transporting means including discrete grippers for the stacks of said series and said grippers having surfaces disposed in a common plane;
