Abstract
A method of manufacturing a substrate configured to be wetted by a device internal to the substrate. The method includes a roll to roll processing method using two different plies to form a substrate incorporating a latent wetting device. The method includes forming a container by creating a vessel in two parts. One part is formed on a bottom ply and another part is formed on a top ply. A wetting agent for wetting the substrates is added to one part of the vessels and the plies and vessel parts are joined using a continuous manufacturing method.
Claims19
A high-speed roll to roll method for making handwetted paper comprising:
- providing a top ply roll and a bottom ply roll;
- making vessel shapes on a bottom ply sheet from the bottom ply roll;
- applying liquid thermal plastic material over the vessel shapes;
- curing the liquid thermoplastic on the bottom ply sheet into a solid to form bottom vessels;
- making vessel tops on a top ply sheet from the top ply roll;
- curing the thermoplastic material into a solid;
- sealing an opening or openings formed in each of the vessel tops or the bottom vessels;
- applying an adhesive ring around the periphery of the vessel tops or the bottom vessels;
- filling the cured vessels on the bottom ply sheet with a liquid agent;
- and
- joining the top ply sheet and the bottom ply sheet to thereby join the vessel tops and vessel bottoms to encapsulate the liquid agent.
The method of claim of 1, wherein the adhesive ring on the vessel tops and a flange on the vessel bottoms are pressed together by joining rolls.
