Abstract

The present disclosure provides a segmented rotary floor stripping pad having a plurality of symmetrical, polygonal pad segments secured together in partially overlapping relation to form an annular pad. The segments are preferably formed from non-woven polyester fibers and are secured radially along the overlapping, adjacent side edges by hot melt glue, ultrasonic welding or by stitching. There is no backing pad, and since the segments are symmetrical, the pad is reversible so that both sides can be used. The plurality of pad segments are secured together in an overlapping manner such that each pad segment presents an angled leading cutting edge and each pair of adjacent pad segments forms a radial fluid channel. Depending on the degree of overlap and the thickness of the pad segment, the presentation angle of the cutting edge can be varied.

Claims (36)

1. A floor stripping pad for stripping wax from a floor comprising:

a plurality of planar, polygonal, symmetrical, pad segments,

each pad segment having a thickness “T”,

each pad segment comprising an open textured, non-woven polymer fiber material,

said plurality of pad segments being secured together in partially overlapping circumferential relation to form an annular segmented pad having an upper stripping surface configured to engage a floor in its entirety and also having an opposed lower stripping surface configured to engage said floor in its entirety,

each pair of adjacent pad segments having overlapping side edge portions which are secured together, between said each pair of adjacent pad segments, along an attachment line extending in a radial direction between a radially inner most edge of each pair of adjacent pad segments to a radially outer most edge of each pair of adjacent pad segments, said radially inner most edges being exposed,

said overlapping side edge portions and said thickness “T” of each of said pad segments cooperating such that each pad segment is disposed at an angle to said floor and presents a radially extending, angled leading cutting edge forward of said attachment line for engagement with said floor in a direction of rotation on each of said upper and lower stripping surfaces, and further such that said annular segmented pad is reversible with said upper and lower stripping surfaces being useful in the same direction of rotation,

said angled leading cutting edges of each pair of adjacent pad segments further forming a radially extending fluid flow channel therebetween in which stripping fluid and dissolved stripped wax is centrifugally pushed radially outward during rotation about an axis on said floor.

2. The floor stripping pad of claim 1 comprising 24 pad segments.

3. The floor stripping pad of claim 1 , wherein said pad segments are secured by a method selected from gluing, ultrasonic welding, and stitching.

4. The floor stripping pad of claim 2 , wherein said pad segments are secured by a method selected from gluing, ultrasonic welding, and stitching.

5. The floor stripping pad of claim 1 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

6. The floor stripping pad of claim 3 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

7. The floor stripping pad of claim 4 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

8. The floor stripping pad of claim 1 further comprising abrasive particles distributed throughout and bonded to said non-woven polymer fiber material.

9. The floor stripping pad of claim 2 further comprising abrasive particles distributed throughout and bonded to said non-woven polymer fiber material.

10. The floor stripping pad of claim 3 further comprising abrasive particles distributed throughout and bonded to said non-woven polymer fiber material.

11. The floor stripping pad of claim 1 further comprising natural fibers distributed throughout said non-woven polymer fiber material.

12. The floor stripping pad of claim 3 further comprising natural fibers distributed throughout said non-woven polymer fiber material.

13. The floor stripping pad of claim 8 further comprising natural fibers distributed throughout said non-woven polymer fiber material.

14. A floor stripping pad for stripping wax from a floor comprising:

a plurality of planar, polygonal, symmetrical, pad segments,

each pad segment having a thickness “T”,

each pad segment formed from an open textured, non-woven polymer fiber material,

said plurality of pad segments being secured together in partially overlapping circumferential relation to form an annular segmented pad, having an upper stripping surface configured to engage a floor over its entirety and also having an opposed lower stripping surface configured to engage said floor over its entirety,

each pair of adjacent pad segments having overlapping side edge portions which are secured along said overlapping side edge portions along an attachment line extending radially,

said overlapping side edge portions and said thickness “T” of each of said pad segment portions cooperating such that each pad segment is disposed at an angle to said floor and presents a radially extending, angled leading cutting edge forward of said attachment line for engagement with said floor in a direction of rotation on each of said upper and lower stripping surfaces,

said angled leading cutting edges of each pair of adjacent pad segments forming a radially extending fluid flow channel therebetween in which stripping fluid and dissolved stripped wax is centrifugally pushed radially outward during rotation on a floor, and

said segmented pad being reversible with said upper and lower stripping surfaces being useful in the same direction of rotation.

15. The floor stripping pad of claim 14 comprising 24 pad segments.

16. The floor stripping pad of claim 14 , wherein said pad segments are secured by a method selected from gluing, ultrasonic welding, and stitching.

17. The floor stripping pad of claim 15 , wherein said pad segments are secured by a method selected from gluing, ultrasonic welding, and stitching.

18. The floor stripping pad of claim 14 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

19. The floor stripping pad of claim 17 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

20. The floor stripping pad of claim 17 , wherein said non-woven polymer fiber material is selected from the group consisting of polyamide, polyester and nylon.

21. The floor stripping pad of claim 14 further comprising abrasive particles distributed throughout and bonded to said non-woven fiber material.
