Abstract

A system for forming a print of a surface of a fabric. The system includes a first plate, a second plate, a pressure measurement film, and a fabric that can be used in a papermaking process. The fabric includes a plurality of knuckles on at least one of its surfaces. A print of the knuckles of the fabric is formed on the pressure measurement film by pressing the fabric against the pressure measurement film between the first plate and the second plate.

First claim

I claim:

1. A system for forming a print of a surface of a structuring fabric, the system comprising:
a first plate having a planar surface;
a second plate having a planar surface;
a pressure measurement film; and
a structuring fabric that can be used to form three-dimensional shapes in a web as part of a papermaking process, the structuring fabric including a plurality of knuckles on at least one of its surfaces,
wherein a print of the knuckles of the structuring fabric is formed on the pressure measurement film by pressing the structuring fabric against the pressure measurement film between the planar surface of the first plate and the planar surface of the second plate.

2. The system according to claim 1 , further comprising:
a first structure that provides a first pressing surface; and
a second structure that provides a second pressing surface,
wherein the first structure, is placed against the planar surface of the first plate, the second structure is placed against the planar surface of the second plate, and the print of the knuckles of the structuring fabric is formed on the pressure measurement film between the fast pressing surface and the second pressing surface.

3. The system according to claim 2 , wherein the first structure is one of paper and rubber.

4. The system according to claim 1 , wherein the first plate and the second plate are connected by a frame structure.

5. The system according to claim 4 , wherein the frame structure is provided with at least one wheel.

6. The system according to claim 1 , further comprising a pump for moving one of the first and second plates towards the other of the first and second plates.

7. The system according to claim 6 , further comprising a transducer for indicating pressure applied by the pump to the plate that moves.

8. The system according to claim 2 , wherein the second structure is one of paper and robber.
