Abstract

An apparatus for notching the back of a book. The apparatus includes a conveyor for moving the book along a conveyor path with the back of the book exposed. A cutter is provided for forming notches in the back of the book. A cutter support disc supports the cutter adjacent the conveyor path and supports the cutter for movement along a path extending transverse to the conveyor path. A first drive is connected with the cutter support dics for moving the cutter along a path extending transverse to the conveyor path. The first drive is operable in a timed relationship with the conveyor to form notches in the back of the book. A second drive is connected with the cutter for moving the cutter relative to the cutter support disc to form notches in the back of the book. The second drive is operable independent of the first drive to maintain the cutter at a speed sufficient to form notches in the back of the book regardless of the speed of movement of the cutter support disc.

Claims

1. An apparatus for notching the back of a book, said apparatus comprising:

conveyor means for moving the book along a conveyor path with the back exposed;

cutter means for forming notches in the back of the book, said cutter means includes at least one blade and a cutter shaft connected with said blade and supporting said blade for rotation about a longitudinal axis of said cutter shaft;

a cutter support disc for supporting said cutter shaft adjacent the conveyor path, said cutter support disc being rotatable about its axis for moving said cutter means along a path extending transverse to the conveyor path;

first drive means connected with said cutter support disc for rotating said cutter support disc about the axis to form notches in the back of the book with said cutter means; and

second drive means connected with said cutter shaft for rotating said cutter shaft about its longitudinal axis, which is coaxial with said disc axis, relative to said cutter support disc to form notches in the back of the book.

2. An apparatus as set forth in claim 1 wherein said cutter means includes means for adjusting the position of said blade along said cutter shaft.

3. An apparatus as set forth in claim 1 wherein said second drive means includes a motor drivingly connected with said cutter shaft for rotating said blade about the longitudinal axis of said cutter shaft.

4. An apparatus as set forth in claim 1 wherein said cutter support disc has at least a pair of bearing portions for receiving axially opposite end portions of said cutter shaft therein.

5. An apparatus as set forth in claim 4 wherein said cutter support disc rotates in a plane which is skewed at an acute angle relative to the conveyor path.

6. An apparatus as set forth in claim 1 further including a hollow shaft affixed to said cutter support disc for supporting said cutter support disc for rotation, said first drive means being drivingly connected with said hollow shaft for rotating said hollow shaft and cutter support disc.

7. An apparatus as set forth in claim 6 further including a drive shaft drivingly connected with said second drive means and with said cutter shaft to transmit drive forces between said second drive means and said cutter shaft, said drive shaft being at least partially disposed coaxially inside of said hollow shaft.

8. An apparatus as set forth in claim 1 wherein said second drive means is operable to maintain said cutter means at a speed sufficient to form notches in the back of the book independent of the speed of movement of said cutter support disc.

9. An apparatus as set forth in claim 1 wherein said cutter support disc is operable in a timed relationship with said conveyor means.

10. An apparatus as set forth in claim 1 wherein said second drive means is operable independent of said first drive means.

11. An apparatus as set forth in claim 1 further including a plurality of blades supported for rotation on said cutter shaft, said plurality of blades being disposed in a side-by-side abutting relationship.
