Abstract
A method for binding together a plurality of paper sheets. The binding process comprises providing a book binding sheet coated on one side with hot-melt adhesive, orienting and securing sheets of paper that will comprise the book to be bound relative to the binding sheet, securing the leading edge of the binding sheet to the front of the book to be bound, severing the secured portion from the remaining binding sheet material, wrapping the binding severed strip around the spine and rear cover and heating the adhesive to produce a permanent bond with the edges of the spine and covers.
Claims12
A method of making a book having a plurality of sheets and a front cover comprising a continuous roll of binding material positioned on a spindle member, one surface of the binding material being coated with a heat softened adhesive on one surface, the width of the material equal to the width of the sheets to be bound together comprising the steps of:
- advancing the binding material into position adjacent said pages;
- securing said binding material to the edge of said front cover of the block of sheets to be bound;
- controlling the amount of binding tape withdrawn from said roll of binding material after being secured to the edge of said front cover so it is proportional to the thickness of the block of sheets to be bound;
- and
- separating a portion of said binding material from the rest of the binding material roll after it has been secured to said front cover edge.
The method of claim 5 wherein said spindle member has a conductive member formed thereon.
The method of claim 6 further including the step of detecting said conductive member when the roll of said conductive member is substantially depleted from said spindle member.
Apparatus for making a book having a plurality of sheets and a front cover comprising a continuous roll of binding material positioned on a spindle member, one surface of the binding material being coated with a heat softened adhesive on one surface, the width of the material equal to the width of the sheets to be bound together comprising:
- means for advancing the binding material into position adjacent said pages;
- means for securing said binding material to the edge of said front cover of the block of sheets to be bound;
- a microprocessor for controlling the amount of binding tape withdrawn from said roll of binding material after being secured to the edge of said front cover so it is proportional to the thickness of the block of sheets to be bound;
- and
- a cutter for separating a portion of said binding material from the rest of the binding material roll after it has been secured to said front cover edge.
