ABSTRACT:
FIELD OF THE INVENTION
This invention relates to children's board books and methods and apparatus for making such board books on binding lines.
BACKGROUND OF THE INVENTION
At present, children's board books as they are known, are printed and assembled by gluing two folded sheets of 18 pt. to 24 pt. chipboard together to make one spread. These spreads are than placed in hoppers and assembled on a binding line by gluing each spread to the next one as they are fed from the hopper. The size of the children's book is then only limited by the number of hoppers of a binding line, allowing one hopper for the cover. These lines normally contain sixteen hoppers which would create a thirty-page book plus the cover.
Should the book require more than sixteen hoppers, a two-stage production has been employed. In this process, two spreads are pre-gathered and glued together prior to being placed on the binding line; and this spread, which is now four pages instead of two, is placed in one hopper thereby allowing the book to attain as much as sixty pages plus a cover. This method, however, requires extensive hand work and becomes quite expensive. Also, adding more hoppers to the bindery becomes very expensive even assuming that the manufacturing facility has the floor space to do this.
SUMMARY OF THE INVENTION
This invention is directed to a board book having at least one spread with four pages integrally attached to one another with an outer reverse, integral fold between pages two and three of the spread. Herein, the preferred four-page spread is folded in a folding machine with a pair of folds that will be placed adjacent the backbone and an outer reverse fold between pages two and three.
Preferably, pages two and three are adhered to one another at the folding machine. It is therefore an object of this invention to provide a method of gluing the spread as part of the spread folding operation.
It is yet another object of this invention to increase the capacity of a binding line to more pages per book with the same number of hoppers using the four-page spread in the feeding hoppers.
It is yet another object of this invention to increase the capacity of the present binding line by using four-page spreads to produce two books on the same line that now only produces one book for the same manufacturing cycle.
In accordance with these and other objects of this invention, which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings.
