Abstract

The present teachings disclose s a process for forming paper domes including: indexing two or more sheets of cut material intended to form a dome when pressed where at least one of the sheets has a cured or dried glue already adhered thereto, applying a glue activator solvent such as water on an exterior top or exterior bottom surface of at least one of the sheets, pressing the sheets together with heat and pressure to form a completed combined sheet with multiple domes, and moving the completed combined sheet.

Claims (29)

1. A process for forming paper domes comprising:

Indexing two or more sheets of cut material intended to form a dome when pressed wherein at least one of the sheets has a cured or dried glue already adhered thereto;

Applying a glue activator solvent such as water on an exterior top or exterior bottom surface of at least one of the sheets;

Pressing the sheets together with heat and pressure to form a completed combined sheet with multiple domes; and

Moving the completed combined sheet,

wherein the sheets are fed together in a non-co-linear or orthogonal manner.

2. The process of claim 1 wherein one or more of the sheets originate from a roll of continuous sheets with cuts intended to form the multiple domes when pressed together.

3. The process of claim 2 further comprising web tensioning and/or unwinding equipment.

4. The process of claim 1 further comprising aligning the sheets prior to pressing.

5. The process of claim 4 wherein one or more of the sheets have one or more registration marks and/or cut(s) used to register a location of each sheet with respect to the other.

6. The process of claim 4 further comprising registering a location of the sheets, prior to pressing, with one or more of the following sensors: a visual, infrared, capacitive, piezoelectric, acoustic, camera, or physical sensor.

7. The process of claim 4 further comprising using independent feed rollers to achieve alignment.

8. The process of claim 4 further comprising using a linear indexing system to achieve alignment.

9. The process of claim 4 further comprising providing a compression zone wherein either sheet is slightly compressed in order to achieve alignment.

10. The process of claim 4 further comprising moving a press to align with the sheets to be pressed.

11. The process of claim 1 further comprising misting an activator such as water on the exterior top or exterior bottom surface of one or more of the sheets.

12. The process of claim 11 further comprising preventing the mist from wetting or activating specific locations of one or more of the sheets.

13. The process of claim 12 wherein the non-activated locations are intended to feed and/or register a location of either sheet.

14. The process of claim 1 wherein the indexing comprises indexing the combined completed sheets after pressing by physically engaging the domes.

15. The process of claim 14 wherein the indexing comprises using a roller with corresponding depressions at each dome.

16. The process of claim 1 further comprising forming a pressed domed paper into one or more of the following: a box, a sleeve, an envelope, a layered cushion, a single sheet.

17. The process of claim 1 further comprising adding or integrating a pressed domed sheet with one or more of the following: a box, a cup, a plate, a container, an RFID tag, an adhesive, or another material.

18. The process of claim 1 comprising activating an external input from a push button or sensor.

19. A process for forming paper domes comprising:

Indexing two or more sheets of cut material intended to form a dome when pressed wherein at least one of the sheets has a cured or dried glue already adhered thereto;

Applying a glue activator solvent such as water on an exterior top or exterior bottom surface of at least one of the sheets;

Pressing the sheets together with heat and pressure to form a completed combined sheet with multiple domes;

Moving the completed combined sheet; and

separating the combined pressed sheet from a section of non-pressed sheet; wherein the sheets are fed together in a non-co-linear or orthogonal manner.
