Abstract

Systems and methods are disclosed to produce a books in which interior staples are hidden. One disclosed example apparatus includes a sensor to detect a position of a book being produced on a binding line. The example book includes signatures coupled by a fastener. The fastener separates a first signature portion from a second signature portion of a first signature. The example apparatus also includes an adhesive dispenser to dispense adhesive to at least one of on or adjacent the fastener to couple the first signature portion and the second signature portion along a first fold adjacent the fastener. The example apparatus also includes a controller to cause the adhesive dispenser to dispense adhesive based on the position of the book detected by the sensor.

First claim

What is claimed is:

1. An apparatus, comprising:
a sensor to detect a position of a book being produced on a binding line, the book comprising signatures coupled by a fastener that extends through the signatures, the fastener to separate a first signature portion from a second signature portion of a first signature;
an adhesive dispenser to dispense adhesive along a first fold adjacent the fastener to couple the first and second signature portions along the first fold to prevent access to a portion of the fastener;
a folder to form a second fold on the first signature portion and a third fold on the second signature portion, the portion of the fastener disposed between the second fold and the third fold, wherein the adhesive is disposed between the second fold and the third fold; and
a controller programmed with instructions to cause the adhesive dispenser to dispense adhesive based on the position of the book detected by the sensor.

2. The apparatus as defined in claim 1 , wherein the second fold is to be brought into engagement with the third fold.

3. The apparatus as defined in claim 1 , further comprising:
a conveyor to transport the book; and
an encoder programmed with instructions to measure at least one of a rate of travel of the conveyor or a distance of travel of the conveyor and to convey at least one of the rate of travel or the distance of travel to the controller.

4. The apparatus as defined in claim 3 , wherein the controller is to determine the position of the book based on at least one of the rate of travel or the distance of travel.

5. The apparatus as defined in claim 1 , further comprising a second sensor to detect a presence or an absence of a fastener in a second book, wherein the controller is programmed with instructions to hold adhesive from the second book based on a detected absence.

6. The apparatus as defined in claim 1 , wherein the first sensor is to detect a first leading edge and a first trailing edge of a first book and a second leading edge and a second trailing edge of a second book, wherein a first distance between the first leading and trailing edges is different from a second distance between the second leading and trailing edges.

7. The apparatus as defined in claim 6 , wherein the controller is programmed with instructions to cause the adhesive dispenser to dispense adhesive to the first book and the second book based on the first and second distances and the respective first and second leading and trailing edges.

8. The apparatus as defined in claim 1 , wherein the adhesive dispenser is to atomize the dispensed adhesive.

9. The apparatus as defined in claim 1 , wherein the first sensor is to detect a leading edge and a trailing edge of the book and the controller is programmed with instructions to cause the adhesive dispenser to dispense adhesive between the leading edge and the trailing edge.

10. The apparatus as defined in claim 9 , wherein the controller is programmed with instructions to dispense between a first distance from the leading edge and a second distance from the trailing edge to prevent the adhesive from flowing out of the book when the book passes through rollers after the book receives the adhesive.

11. The apparatus as defined in claim 1 , wherein the adhesive dispenser comprises an adjuster to change at least one of a rate of adhesive dispensed, a width of the adhesive dispensed, or an amount of adhesive dispensed.

12. The apparatus as defined in claim 1 , further comprising rollers to join the first signature portion and the second signature portion.

13. The apparatus as defined in claim 1 , further comprising:
a second sensor to detect a presence or an absence of a fastener in a second book; and
a diverter programmed with instructions to move the second book away from the adhesive dispenser.

14. The apparatus as defined in claim 1 , further comprising a reciprocating blade to place the book onto a conveyor after the adhesive has been dispensed.

15. The apparatus as defined in claim 1 , wherein the first signature is an innermost signature of the book.

16. The apparatus as defined in claim 1 , wherein the fastener includes a staple, and wherein the portion includes staple ends.

17. The apparatus as defined in claim 2 , wherein the adhesive is disposed between the first fold and the engagement of the second fold and the third fold.

18. The apparatus as defined in claim 12 , wherein the rollers are to form the first fold.

19. A book, comprising:
signatures coupled together with a fastener, the fastener to extend through the signatures and separate a first signature portion of a first signature from a second signature portion of the first signature;
adhesive coupling the first signature portion and the second signature portion adjacent a first fold that is positioned proximate the fastener, wherein coupling the first and second portions is to prevent access to ends of the fastener;
a second fold on the first signature portion; and
a third fold on the second signature portion, the second fold in engagement with the third fold, and at least a portion of the fastener positioned between the first fold, the second fold and the third fold.

20. The book as defined in claim 19 , wherein a ratio of a first length from the first fold to the second and third folds to a second length from the second and third folds to an end of the signatures is approximately 0.10 to 0.30.

21. The book as defined in claim 19 , wherein the first fold is adjacent a fourth fold of a second signature.

22. The book as defined in claim 21 , wherein the fastener passes through the first and fourth folds.
