Claims
- 1. A book comprising:
- a plurality of sheets of paper bound together along one edge using a substantially continuous hot melt adhesive located along the bound edge that extends for substantially the entire length of the edge; and
- a cover having a spine; and
- wherein the book can lay flat when opened such that consecutive pages on separate sheets can lay in substantially the same plane without damaging the bond of the sheets to each other or to the cover.
- 2. A book comprising:
- a plurality of sheets of paper bound together along one edge using a substantially continuous hot melt adhesive located along the bound edge that extends for substantially the entire length of the edge; and
- a cover having a spine;
- wherein the sheets of paper are bound together by placing a backless, hot melt adhesive material sheet along the top horizontal edge of the plurality of sheets of paper; heating the hot melt adhesive material sheet to melt the hot melt adhesive material sheet onto the edge of the sheets of paper to cause the liquid adhesive to penetrate the seams between the sheets of paper to bind the sheets of paper together without pressing the liquid adhesive downwardly into the seams between the sheets of paper; and maintaining a temperature profile across the top of the edge of the sheets of paper at a sufficiently high temperature to prevent the adhesive material from drying before the paper sheets are properly bound and to facilitate adherence of the adhesive material onto the sheets of paper by insulating the edge of the sheets of paper during heating from the remainder of the apparatus; and placing the spine of a cover against the melted hot melt adhesive on the edge of the sheets of paper to bind the cover to the sheets of paper; and
- wherein the book can lay flat when opened such that consecutive pages on separate sheets can lay in substantially the same plane without damaging the bond of the sheets to each other or to the cover.
- 3. A book comprising:
- a plurality of sheets of paper bound together along one edge using a substantially continuous hot melt adhesive located along the bound edge that extends for substantially the entire length of the edge; and
- a cover having a spine;
- wherein the book can lay flat when opened such that consecutive pages on separate sheets can lay in substantially the same plane without damaging the bond of the sheets to each other or to the cover; and
- wherein the book is made by the steps of:
- placing a backless, hot melt adhesive material sheet along the top horizontal edge of the plurality of sheets of paper;
- heating the hot melt adhesive material sheet to melt the hot melt adhesive material sheet onto the edge of the sheets of paper to cause the liquid adhesive to penetrate the seams between the sheets of paper to bind the sheets of paper together without pressing the liquid adhesive downwardly into the seams between the sheets of paper;
- maintaining a temperature profile across the top of the edge of the sheets of paper at a sufficiently high temperature to prevent the adhesive material from drying before the paper sheets are properly bound and to facilitate adherence of the adhesive material onto the sheets of paper by insulating the edge of the sheets of paper during heating from the remainder of the apparatus; and
- placing the spine of a cover against the melted hot melt adhesive on the edge of the sheets of paper to bind the cover to the sheets of paper.
- 4. A book comprising:
- a plurality of sheets of paper bound together along one edge using a hot melt adhesive located along the bound edge; and
- a cover having a spine, wherein the spine of the cover is fixed to the edges of the sheets to prevent separation of the cover from the sheets; and
- wherein the book can lay flat when opened such that consecutive pages on separate sheets can lay in substantially the same plane without damaging the bond of the sheets to each other or to the cover.
- 5. The book of claim 1 wherein when the book lays flat when opened consecutive pages on separate sheets do not wedge against each other.
- 6. The book of claim 1 wherein the spine of the cover is fixed to the edges of the sheets to prevent separation of the cover from the sheets.
- 7. The book of claim 1 wherein the hot melt adhesive has a thickness of less than 0.009 inches.
