Abstract

Claims (33)

1 . A method of monitoring a sheet of material comprising:

i. advancing a sheet of material that moves in a machine direction (MD);

ii. applying a series of reference markers and associated tracing codes onto the sheet of material along the MD;

iii. recording the associated tracing codes that have been applied to create a database of tracing codes; and

iv. measuring a first physical property of the sheet of material along the MD to generate a measurement profile that is recorded wherein measurements of the first physical property are synchronized with the associated tracing codes from the database so that different portions of the measurement profile are associated with one or more accompanying associated tracing codes,

wherein step (iv) uses a first sensor that is mounted to a first scanner that traverses back and forth along a cross direction (CD) across the sheet of material wherein the first sensor measures first properties from first interrogation spots on the sheet of material.

2 . The method of claim 1 further comprising measuring a second physical property of the sheet of material along the MD to generate a second measurement profile that is recorded wherein measurements of the second physical property are synchronized with the associated tracing codes from the database so that different portions of the second measurement profile are associated with one or more accompanying the associated tracing codes.

3 . The method of claim 2 wherein measuring the second physical property uses a second sensor that is mounted on a second scanner, which is located downstream of the first sensor, and that traverses back and forth along the CD across the sheet of material, wherein the second sensor measures the second properties from second interrogations spots on the sheet of material, wherein operation of the second scanner is synchronized using the associated tracing codes from the database so that the second interrogation spots match the first interrogation spots.

4 . The method of claim 1 comprising identifying a position of a reference marker and initiate measuring the first physical property using the identified position of the reference marker to synchronize movement of the sheet of material with the measurement.

5 . The method of claim 1 comprising identifying positions of a plurality of reference markers and determining whether a distance or distances between the plurality of reference markers have changed.

6 . A method of preparing electrodes comprising:

i. providing a sheet of metal substrate which moves in a machine direction (MD);

ii. applying one or more coatings of electrode material onto the sheet of metal substrate to form a moving sheet of metal substrate having one or more coated regions and one or more uncoated regions;

iii. applying a series of reference markers and associated tracing codes onto the sheet of metal substrate, wherein step (ii) occurs before or after step (iii), to form a moving sheet of metal substrate having one or more coated regions and one or more uncoated regions wherein (a) in the case wherein step (ii) occurs before step (iii), the series of reference markers and the associated tracing codes are applied onto the one or more uncoated regions whereas (b) in the case wherein step (iii) occurs after step (ii), the series of reference markers and the associated tracing codes are applied onto the one or more uncoated regions and/or onto one or more coated regions;

iv. recording the associated tracing codes that have been applied to create a database of the associated tracing codes;

v. measuring a first physical property of the one or more of the coated regions along the MD to generate a measurement profile that is recorded wherein measurements of the first physical property are synchronized with the associated tracing codes from the database so that different portions of the measurement profile are associated with one or more accompanying the associated tracing codes, and

after step (v), cutting the sheet of metal substrate to form a plurality of electrodes; and using the recorded associated tracing codes from the database to assign each electrode with a portion of the measurement profile that is recorded.

7 . The method of claim 6 wherein step (ii) occurs before step (iii) and the series of reference markers and the associated tracing codes are applied onto the sheet of metal substrate that is defined by one or more uncoated regions.

8 . The method of claim 6 wherein step (v) uses a first sensor that is mounted to a first scanner that traverses back and forth along the cross direction (CD) across the sheet of metal substrate wherein the first sensor measures first properties from first interrogations spots on one or more of the coated regions.

9 . The method of claim 6 further comprising measuring a second physical property of the one or more of the coated regions along the MD to generate a second measurement profile that is recorded wherein measurements of the second physical property are synchronized with the associated tracing codes from the database so that different portions of the second measurement profile are associated with one or more accompanying the associated tracing codes.

10 . The method of claim 9 wherein measuring the second physical property comprises uses a second sensor that is mounted on a second scanner, which is located downstream of the first sensor, and that traverses back and forth along the CD across the sheet of metal substrate wherein the second sensor measures the second properties from second interrogations spots on one or more of the coated regions, wherein operation of the second scanner is synchronized using the associated tracing codes from the database, so that the second interrogation spots match the first interrogation spots.

11 . The method of claim 6 comprising identifying a position of a reference marker and initiate measuring the first physical property using the position of the reference marker to synchronize movement of the sheet of metal substrate with the measurement.

12 . The method of claim 11 comprising using an optical character scanner to identify the position of the reference marker.

13 . The method of claim 6 comprising identifying positions of a plurality of reference markers and determining whether a distance, or distances between the plurality of reference markers has changed.

14 . The method of claim 6 comprising changing the speed that the sheet of metal substrate moves in response to changes in a distance, or distances between the plurality of reference markers, so that step (v) is synchronized.

15 . The method of claim 6 wherein the database includes a library of the associated tracing codes and their corresponding measurement profiles.

16 . The method of claim 15 wherein the measurement profiles contain two or more sets of measurement profiles.

17 . A method of monitoring a sheet of material comprising:

i. advancing a sheet of material that moves in a machine direction (MD);

ii. applying a series of MD position marks and corresponding position codes onto the sheet of material along the MD;

iii. recording the corresponding position codes that have been applied to create a database of codes; and

iv. measuring a physical property of the sheet of material along the MD to generate a measurement profile that is recorded wherein measurements of the physical property are synchronized with the corresponding position codes from the database so that different portions of the measurement profile are associated with one or more accompanying the corresponding position codes; and

wherein step (iv) uses a first sensor that is mounted to a first scanner that traverses back and forth along a cross direction (CD) across the sheet of material wherein the first sensor measures first properties from first interrogations spots on the sheet of material.
