Methods and apparatus to score book covers
View Patent ↗Apparatus and methods to score book covers are described. An example scoring apparatus includes a first scoring roll to oppose a corresponding second scoring roll to process a cover at a first location on a first side of the cover, and a third scoring roll to oppose a corresponding fourth scoring roll to process the cover at a second location on the first side of the cover. The first location and the second location correspond substantially to the thickness of a book to which the cover is to be applied. The first and the third scoring rolls are mechanically driven and rotate about a first axis of rotation and the second and the fourth scoring rolls rotate freely about a second axis of rotation.

8. A scoring apparatus comprising:
a housing having a first shaft parallel to a second shaft;
a first plurality of scoring rolls mounted to the first shaft opposite a
corresponding second plurality of scoring rolls mounted on the second shaft to provide a first plurality of score lines to a cover, wherein at least a first score line and a second score line of the first plurality of score lines correspond substantially to a thickness of a book block to which the cover is to be applied, and wherein the first plurality of scoring rolls are mechanically driven and the second plurality of scoring rolls rotate freely; and
a first slider to couple at least one scoring roll from the second plurality of scoring rolls to the second shaft the first slider having a first adjustor moveable between a first position and a second position to enable the at least one scoring roll to be independently adjustable in a first linear direction and a second adjustor to enable the at least one scoring roll to be adjustable in a second linear direction relative to the first plurality of scoring rolls and at least another scoring roll from the second plurality of scoring rolls wherein the first linear direction is different than the second linear direction.
9. An apparatus as defined in claim 8 , further comprising a third plurality of scoring rolls mounted to a third shaft opposite a corresponding fourth plurality of scoring rolls mounted to a fourth shaft parallel to the third shaft, wherein the third plurality of scoring rolls and the corresponding fourth plurality of scoring rolls provide a corresponding second plurality of score lines to the cover, wherein at least a third score line of the second plurality of score lines is adjacent and spaced outwardly from the at least first or second score lines of the first plurality of score lines.
10. An apparatus as defined in claim 9 , wherein the first plurality of score lines and the second plurality of score lines are located on a same side of the cover.
11. An apparatus as defined in claim 9 , wherein the third plurality of scoring rolls are mechanically driven and the fourth plurality of scoring rolls rotate freely.
12. A method to score a book cover, the method comprising:
mounting at least one scoring roll from a first set of scoring rolls to a shaft via a first slider;
moving a first adjustor of the slider between a first position and a second position to enable movement of the first scoring roll in a first lateral direction along the shaft;
moving a second adjustor of the slider between a third position and a fourth position to enable movement of the first scoring roll in a second lateral direction different than the first lateral direction, the first and second adjustors to enable the first scoring roll to be independently adjustable in the first and second lateral directions relative to a second scoring roll of the first set of scoring rolls opposing the first scoring roll and at least one of a third scoring roll from a second set of scoring rolls or a fourth scoring roll from the second set of scoring rolls;
processing the book cover through the first set of scoring rolls to provide a first score line to the book cover at a first location and the second set of scoring rolls to provide a second score line to the book cover at a second location different from the first location; and
driving the second scoring roll of the first set of scoring rolls and the fourth scoring roll of the second set of scoring rolls via a first drive of a binding system to which the first set of scoring rolls and the second set of scoring rolls are to be operatively coupled, and wherein the first a scoring roll of the first set of scoring rolls and the third scoring roll of the second set of scoring rolls rotate freely.
13. A method as defined in claim 12 , further comprising manually adjusting a third set of scoring rolls to be at a distance from a fourth set of scoring rolls, wherein the third set of scoring rolls provides a third score line to the cover adjacent and parallel to the first score line and the fourth set of scoring rolls provides a fourth score line to the cover adjacent and parallel to the second score line.
14. A method as defined in claim 13 , further comprising mechanically driving a fifth scoring roll of the third set of scoring rolls and a sixth scoring roll of the second set of scoring rolls via the first drive, and wherein a seventh scoring roll of the third set of scoring rolls and a eighth scoring roll of the fourth set of scoring rolls rotate freely.
