Abstract

A method, a wiping apparatus, and a wiping system to store web material in a multi-folded state in a web storage chamber.

First claim

What is claimed is:

1. An apparatus, comprising:
a web material including a plurality of segment portions to wipe a fluid applicator;
a web storage chamber having an input opening and an output opening, the web storage chamber to store the web material in a folded state; and
a driver system to remove a portion of the web material from the web storage chamber and wipe the fluid applicator with the web material.

2. The apparatus of claim 1 , wherein the driver system comprises a web input device to sequentially place the segment portions of the web material into the web storage chamber through the input opening.

3. The apparatus of claim 1 , wherein the web input device compresses the web material in the web storage chamber.

4. The apparatus of claim 1 , wherein the driver system comprises a number of rollers around which the web material is moved.

5. The apparatus of claim 4 , wherein the number of rollers comprise supplemental rollers to extend a path of the web material and provide additional tension to reduce creases in the web material.

6. The apparatus of claim 1 , wherein the web storage chamber further comprises a plurality of anti-catch guards disposed proximate to the input opening to direct the web material received through the input opening.

7. The apparatus of claim 6 , wherein the anti-catch guards comprise a slanted surface having a plurality of ridges.

8. The apparatus of claim 1 , wherein the web storage chamber further comprises a plurality of choking stages, each choking stage to prevent the web material from binding.

9. The apparatus of claim 8 , wherein a folding density of the web material is reduced as the web material passes through respective choking stages, the folding density of the web material corresponding to a number of folds per amount of web material.

10. The apparatus of claim 1 , wherein the driver system comprises:
a plurality of rollers configured to sequentially transport the web material; and
a web applicator to press respective segment portions of the web material against the fluid applicator to perform the wiping operation.

11. The apparatus of claim 1 , wherein the web material is in a continuous loop.

12. The apparatus of claim 11 , wherein the loop of web material extends simultaneously into the input opening and out of the output openings of the web storage chamber.

13. The apparatus of claim 1 , wherein the fluid applicator is a page-wide, inkjet printhead array.

14. A device comprising:
a web material including a plurality of segment portions to wipe a fluid applicator; and
a web storage chamber including an input opening, an output opening, and a choking stage, the web storage chamber to store the web material in a folded state;
the choking stage to decrease a folding density of the web material as the web material passes there through, the folding density of the web material corresponding to a number of folds per amount of web material.

15. The system of claim 14 , further comprising a plurality of successive choking stages, each choking stage to decrease the folding density of the web material as the web material passes there through.

16. The apparatus of claim 14 , wherein the web storage chamber further comprises a plurality of anti-catch guards disposed proximate to the input opening to direct the web material that is received through the input opening.

17. The apparatus of claim 16 , wherein the anti-catch guards comprise a slanted surface having a plurality of ridges.

18. A method of operating a wiping apparatus, the method comprising:
storing a web material including a plurality of segment portions in a folded state in a web storage chamber of the apparatus, the web storage chamber having an input opening and an output opening;
unfolding the web material from the web storage chamber by extracting the web material through the output opening;
wiping a fluid applicator with the web material extracted from the web storage chamber; and
refolding the web material into the web storage chamber through the input opening.

19. The method of claim 18 , further comprising transporting the web material in the web storage chamber through a plurality of choking stages in which a folding density of the web material is progressively reduced as the web material passes through each choking stage, where the folding density of the web material corresponds to a number of folds per amount of web material.

20. The method of claim 18 , further comprising directing the web material with a plurality of anti-catch guards disposed proximate to the input opening.
