Multi Grit Anti Chatter Sand Paper
A sanding paper for use with a floor sander having one direction sanding comprising a paper sleeve or belt having a length and a width and a first surface and a second surface joined together and running parallel along the length of the sand paper wherein the first surface is disposed on the sander to apply to the floor first and the second to follow immediately thereafter and wherein the first surface has a grit which is more coarse than the second surface. The sanding paper first grit is a grit between 24-60 and the second grit is between 80 and 120 grit. In place of a middle grit, The intermediate surface between the first surface and second surface and wherein the first surface is between 24 and 40 grit, the intermediate surface between 41 and 80 grit and the third surface between 80 and 120 grit.

Wood floor refinishing is done by a floor sander which consist of a drum turned by a motor. The drum has sand paper attached to it in various ways sleeved cut paper or a belt. Older floors typically has to be sanded three times. Newly installed wood floors require two or three sandings. Running the sander over the wood floor separately with each grit course medium and then fine requiring many hours on small projects days on average projects weeks on larger projects Utilizing present invention floors new or old only has to be sanded one time. Saving many man hours and trips to do the work.
FIELD OF INVENTIONThe invention applies to floor sanders.
PRIOR ARTHas multiple sanding heads utilized but not with a common piece of sand paper but not utilizing the process described within.
In most cases in the prior art what is done a course grit sander moves over a floor followed up with a fine grit sander and this requires a little less then twice the time of utilizing the present invention
The invention provides two or more sanding papers tied together with the seal or manufactured as a single unit with course grit adjoining fine grit in such as way that the course grit may sand the floor followed by the fine grit at the same time. The invention also is an anti-chatter paper which causes less vibration in the way the paper is tied together and or the padding.
Method of padding the sand paper and or the backing of the sand paper is also described which allows the pressure on the fine grit and course grit to be buried in accordance with the requirements with making contact with the grits of two or more different textures.
While padding is the word that is used it may also be accomplished by having more resin or thicker paper or backing by one or the other of the two or more grits as long as those sand papers are tied together by the same sand paper.
As can best be seen by reference in
In order to provide that the grits of varying heights can be pushed at the right pressures against the floor using a motorized sander
In
In this case the invention also includes the process of utilizing a single belt to do at Least two sanding operations simultaneously in order to save time whereby the sander moves in a single direction across the floor engaging a course grit (C) and then the intermediate grit (B) followed by fine grit (A).
It may be described as a sanding paper for use with a sander having one direction sanding comprising a sanding paper having a length and a width and a first surface and a second surface joined together and running parallel along the length of the paper wherein the first surface is disposed on the sander to apply to the floor first and the second to follow immediately thereafter and wherein the first surface has a grit which is more coarse than the second surface. The sanding paper with two grits range from 40 to 60 grit (B).
Test area 300 square feet white oak flooring using 8 inch belt sander used standard off the shelf 40 grit for first sanding. Had the said multi grit belt manufactured the company adjusted the amount of resin on the paper to make the sand paper the same thickness as so the two grit were even the so called seal or seem tape was Kevlar with two grits only 60 grit and 100 grit
Sanded the floor with the present invention which require half the time of prior art. Also the sand paper solved another huge problem in the wood floor refinishing industry Normally after a floor is sanded with a drum or belt sander the wood floor has what is called chatter marks in the floor which is caused by the paper and belts vibrating. which requires more time using a disk sander to remove the chatter marks from the wood floor. the test showed that the paper being in two pieces as in
1.
2.
3. (A) Fine grit
4. (B) Intermediate grit
5. (C) Course grit
6. 3-2 Backing fine grit
7. 3-1 Backing intermediate grit
8. (1) Seal seam tape
9. (2) Paper joined to make sleeve with seal seam tape

14. (4) Drum (5) Top tension roller to hold belt

18. (6) Slot where sand paper is attached to drum no seal seam tape needed.
19. (7) Cushion on drum
Claims
1. A sanding paper for use with a floor sander having one direction sanding comprising a sander paper sleeve or belt having a length and a width and a first surface and a second surface joined together and running parallel along the length of the paper wherein the first surface is disposed on the sander to apply to the floor first and the second to follow immediately thereafter and wherein the first surface has a grit which is more coarse than the second or third surface.
2. The sanding paper of claim 1 wherein the first grit is a grit between 24-60 and the second grit is between 80 and 120 grit.
3. The paper of claim 1 comprising a seam tape or seal on the back which makes the sand paper not vibrate which is a result of smoother sanding of a wood floor.
4. The belt of claim 1 comprising an intermediate surface between the first surface and second surface and wherein the first surface is between 24 and 40 grit, the intermediate surface between 41 and 80 grit and the third surface between 80 and 120 grit.
5. The sand paper of claim 1 the seal and backing of paper is an anti-chatter which causes less chatter of a belt or paper because it reduces vibration
6. The sand paper of claim 1 wherein the belt is thicker padding under certain grits than others in order to apply equal pressure regardless of grit size.
7. The sand paper of claim 1 in addition to the seal the thicker resin of the various grits to make them the same thickness helps reduce chatter.
8. The sand paper of claim 1 backing padding or resin is manipulated. As so that all grits have the same thickness.
