Abstract
A book binding assembly in the form of a stack of hardcovers for making hardcover books, with the hardcovers having pressure sensitive adhesives on both sides for securing a cover wrap onto the hardcovers. Liner sheets are disposed over the upper hardcover and intermediate the hardcovers of the stack to protect the various adhesive elements. In addition, the liner sheets possess attributes including a fold line which enable an end user to accurately apply a cover wrap to the hardcover on which the liner sheet is disposed.

A book binding assembly comprising:
- a plurality of substantially identical liner sheets;
- a plurality of substantially identical hardcovers, with each of the hardcovers having first and second outer orthogonal edges, and third and fourth outer edges opposite the respective first and second edges and comprising a front cover piece, a back cover piece and a spine piece, with each of the pieces having a front side and a back side;
- a pressure sensitive front adhesive layer covering substantially all of the front side of the front and back cover pieces and the spine piece of the hardcovers;
- a pressure sensitive rear adhesive extending along a periphery of the backside of at least the front cover and back cover pieces of the hardcovers and extending a distance E from the outer edges of the hardcovers;
- a first one of the liner sheets covering the front adhesive layer of a first one of the hardcovers;
- and
- a second one of the liner sheets covering the rear adhesive of the first one of the hardcovers and covering the front adhesive layer of a second one of the hardcovers;
- with the liner sheets each possessing a fold line which divides each liner sheet into a flap member and a central portion, with the liner sheets positioned on the hardcovers such that the fold lines are displaced away from the hardcovers a distance X1 from the first edges of the hardcovers, with the distance X1 being at least as great as distance E and positioned such that the central portions cover the entire front adhesive layers of the respective first and second hardcovers of the plurality of substantially identical hardcovers;
- and
- whereby the liner sheets can be used as a guide in positioning cover wraps on the hardcovers including aligning an edge of the cover wraps with the fold lines of the liner sheets associated with the hardcovers.

A book binding assembly comprising:
- first, second and third substantially identical hardcovers, with each hardcover having outer edges including first and second outer orthogonal edges and including a front side, with a front adhesive layer disposed on the front side, and a backside, with a rear adhesive disposed on the backside and extending a distance E from the outer edges of the hardcover;
- first, second and third substantially identical liner sheets, with each liner sheet including means for defining a fold line, with the fold line dividing each of the liner sheets into a flap member and a central portion;
- and
- with the central portion of the first liner sheet being disposed over the first hardcover and covering the entire front adhesive layer of the first hardcover, with the central portion of the second liner sheet being disposed intermediate the first and second hardcovers and covering the entire front adhesive layer of the second hardcover, with the central portion of the third liner sheet being disposed intermediate the second and third hardcovers and covering the entire front adhesive layer of the third hardcover,
- with the liner sheets being positioned relative to the respective hardcovers such that the fold lines of the liner sheets are displaced a distance X1 from the first edges of the respective hardcovers, with the distance X1 being at least as great as distance E;
- and
- whereby the flap members can be used to aid in accurately positioning cover wraps on the respective hardcovers.

- first, second and third substantially identical hardcovers, with each hardcover including a front side, with a front adhesive layer disposed on the front side, and a back side, with a rear adhesive disposed on the backside;
- first, second and third substantially identical liner sheets, with each liner sheet including a fold line, with the fold line dividing each liner sheet into a flap member and a central portion;
- with the central portion of the first liner sheet being disposed over the first hardcover and covering the entire front adhesive layer of the first hardcover, with the second liner sheet being disposed intermediate the first and second hardcovers and contacting the rear adhesive and front adhesive layers of the respective first and second hardcovers, with the central portion of the second liner sheet covering the entire front adhesive layer of the second hardcover and with the third liner sheet being disposed intermediate the second and third hardcovers and contacting the rear adhesive and front adhesive layer of the respective second and third hardcovers with the central portion of the third liner sheet covering the entire front adhesive layer of the third hardcover;
- and
- with the first, second and third liner sheets each folded in a same direction about the respective fold lines such that the flap member of the second liner sheet is positioned adjacent the central portion of the second liner sheet, with the flap member of the second liner sheet disposed intermediate the central portion of the second liner sheet and the first hardcover;
- whereby the flap members can be used to aid In accurately positioning cover wraps on the respective hardcovers.
