A BOOKBINDER HAVING RESETTABLE STRIP GUIDES ABSTRACT OF THE DISCLOSURE Apparatus for applying a piece of adhesive strip to a stack of sheets having a thickness within one of several thickness ranges, the width of the adhesive strip to be applied being dependent on the thickness range to which the thickness of the stack of sheets corresponds. The apparatus includes a pair of strip guides and means, responsive to the thickness of the stack of sheets, for moving the strip guides to initial positions, said means including linkage means. The apparatus also includes: bipartite clamping means; and means, coupled to the linkage means, for moving the clamping means into engagement with the stack of sheets and for stressing play out of said linkage means, thereby moving the strip guides into one of a set of several sets of positions, each set corresponding to one of the thickness ranges. Each set of positions is suitable for supporting a different one of a plurality of adhesive strips, each strip having a different but standard size width. Binding of the engaged stack is accomplished with an arrangement of platens; means for rotating the clamping means, thereby moving an edge of the stack into abutment with one side of a supported strip, and for moving the other side of the adhesive strip into abut- ment with at least one of the platens; and means for biasing the platens against the other side of the strip to fix the strip to the stack of sheets.
