Abstract

A page binding support tray has vibratory page alignment. The tray has a floor having a lower-most corner at which two side walls of the tray converge. Previously edge-glued printed uniformly sized pages are received to form a stack upon the tray floor and vibration of the tray ensures that edges of the page bear against the side walls of the tray to align the pages prior to edge-pressing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

Preferred forms of the present invention will now be described by way of example with reference to the accompanying drawings wherein:

FIG. 1 is a schematic illustration of a page conveyed along a path and passing a pagewidth print head and an adhesive applicator;

FIG. 2 is a schematic illustration of a page having an adhesive strip adjacent one edge thereof;

FIG. 3 is a table, schematically illustrating the principles of five alternative adhesive application methods;

FIG. 4 is a schematic elevational view of a number of pages with all but the top page having a strip of adhesive applied to an upper surface adjacent to an edge to be bound;

FIG. 5 is a schematic elevational view of a stack of pages with all but the bottom page having a strip of adhesive applied to a lower surface thereof adjacent to an edge to be bound;

FIG. 6 is a schematic elevational view of a stack of pages with a first part of a two-part adhesive applied to the upper surface of all but the top page and a second part of a two-part adhesive applied to the bottom surface of all but the bottom page,

FIG. 7 is a schematic perspective view of a page binding support tray situated immediately down-line of the adhesive applicator,

FIG. 8 is a schematic cross-sectional elevational view of the page binding support tray of FIG. 7 showing a first page having a strip of adhesive adjacent its edge at an upper surface en route thereto,

FIG. 9 is a schematic cross-sectional elevational view of the page binding support tray and page of FIG. 8, with the page closer to its rest position,

FIG. 10 is a schematic cross-sectional elevational view of the page binding support tray and page of FIGS. 8 and 9, with the page at rest thereon,

FIGS. 11,

12 and

13 are schematic cross-sectional elevational view of the page binding support tray showing a second page as it progresses to rest upon the first page,

FIG. 14 is a schematic cross-sectional elevational view of the page binding support tray having a number of pages resting thereon to be bound, with all but the top page having an upwardly facing strip of adhesive adjacent an edge thereof,

FIG. 15 shows the progression of a page-binding press toward the edge of the stacked pages,

FIG. 16 shows the page binding support tray with pages bound along their edge by application of the binding press,

FIG. 17 is a cross-sectional elevational view of the page binding support tray having a number of individual volumes resting thereon, with a top volume ready to be pressed,

FIG. 18 is a schematic cross-sectional elevational view of the page binding support tray and volumes of FIG. 17, with all volumes having been pressed, one upon another,

FIG. 19 is a schematic perspective illustration of a number of volumes having been bound,

FIG. 20 is schematic elevational view of a page binding support tray having an alternative press,

FIGS. 21 and 22 are schematic perspective views of a portion of the alternative press of FIG. 20, and

FIG. 23 is a schematic elevational view of a page binding support tray having an alternative press at a trailing edge of a stack of pages to be bound.

Claims

1. An apparatus comprising:

2. The apparatus of claim 1 wherein adhesive is applied adjacent an edge of at least one of the pages.

3. The apparatus of claim 1 wherein the tray has a base including at least one corner portion that is lower than other portions of the base.

4. The apparatus of claim 3 wherein the tray includes at least two sidewalls extending substantially perpendicularly to each other and against which perpendicular edges of the pages bear for alignment of the pages within the stack.

5. The apparatus of claim 1 wherein vibration of the tray is dampened by dampers.

6. The apparatus of claim 1 wherein the tray is supported by a frame.

7. The apparatus of claim 6 wherein the fray is suspended from the frame.

8. The apparatus of claim 6 wherein dampers extend from the tray to the frame.

9. The apparatus of claim 1 wherein the vibrator is a subsonic vibrator.

10. The apparatus of claim 3 wherein the base of the tray is of adjustable height relative to the press device, so as to ensure that an upper page of the stack is situated at a predefined level for interaction with the press device.

11. A method of bonding pages in a stack of pages using an apparatus comprising a tray, a vibrator and a press device, the method including the steps of:

12. The method claim of

11 wherein said press device includes a plurality of semi-circular disks each spaced apart and fixedly mounted to a rotatably driven shaft.

13. The method of claim 11 wherein said vibrator is a subsonic vibrator.

14. The method of claim 11 wherein the step of aligning the pages comprises aligning the pages in at least one corner portion of a base of the tray, the corner being lower than other portions of the base.

15. The method of claim 14 wherein the tray has at least two sidewalls extending substantially perpendicularly to each other, and wherein the step of aligning the pages comprises causing perpendicular edges of the pages to bear, for alignment within the stack, against said sidewalls.

16. The method of claim 11 wherein the step of inducing vibration comprises dampening the induced vibration by dampers.

17. The method of claim 11 comprising the step, prior to the step of delivering pages, of supporting the tray by a frame.

18. The method of claim 17 wherein the step of supporting the tray comprises suspending the tray from the frame.

19. The method of claim 17 wherein the step of supporting the tray comprises providing dampers such that the dampers extend from the tray to the frame.

20. The method of claim 11 wherein the step of inducing vibration comprises inducing vibration by the vibrator wherein the vibrator is a subsonic vibrator.

21. The method of claim 14 comprising the step of adjusting the height of the support surface relative to the press device, thereby ensuring that an upper page of the stack is situated at a predefined level for interaction with the press device.
