Claim Text:
1. A device for preforming spine regions in planar book cases having a spine region including a pair of joint areas that connect to a pair of case boards, comprising: a forming component including a base element and at least one additional forming element that is adjustable relative to the base element and together with the base element define a profile of the forming component for preforming the spine region the book case; a first, main drive for displacing the forming component toward an inner side of the spine region and thereby raising the spine region out of the plane of the book case; and a second, adjusting drive that adjusts said at least one additional forming element independently of the first drive and thereby alters the profile of the forming component; wherein regions of the profile of the forming component facing the inner side of the spine region remain spaced apart from the spine region during said raising of the spine region from the plane of the book case; and wherein the at least one additional forming element includes a central and two laterally adjacent forming elements, each having convexly curved surfaces that in part define the profile and contact the spine region during forming; and said regions of the profile that remain spaced apart are between the curved surface of the central forming element and the curved surfaces of adjacent forming elements.
