3 Claims.

This invention relates to new and improved polishing and cutting buffs particularly of the type embodying pleated textile material as the buifing, polishing and cutting means.

It is the principal object of this invention to provide a bufi of the nature disclosed having a construction which lends itself to faster and more economical manufacture, resulting in reduced cost in manufacturing industries requiring the use of these buffs; and a further object of the invention resides in the provision of a buff as described comprising a central hub which may be of any material such as cardboard, wood, plastic, etc., about the periphery of which there is wound a plurality of times a bias cut pre-pleated elongated strip of textile material, the hub being located at the center of this wrapped around formation, and there being a band or the like which is placed about the wrapped around material in line with the hub, said band being then tightly brought up so that the pleated material is very tightly secured at the periphery of the hub, said bias cut pleated material being folded over and the folds sewed together so that the pleated buffing material extends radially from and in the same plane with the hub.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is a view in side elevation of a buff according to the invention, a part being broken away;

Fig. 2 is a diametric cross sectional view through the buff; and

Fig. 3 is an enlarged cross sectional view illustrating the recessed hub, parts being broken away.

This invention presents the first successful effort to make a buff easily and quickly of bias cut pleated material so as to considerably reduce the hand work required and render the buff much less expensive to make. The superiorities of bias cut pleated buffs over merely gathered or conventional buffs are that the new buffs out quicker, wear longer, polish better, present a face with more polishing pockets, like a honeycomb, the pockets being evenly and correctly spaced rather than haphazard, and in general these buffs are much more favorably regarded in all kinds of industry, except that the price is necessarily higher than for ordinary buffs.

This invention provides a buff which is made of bias cut pre-pleated material but which is easy and quick to make accommodating itself to high speed production and consequent lowering of costs.

Shown in Fig. 1, there is a centrally apertured hub H] which may be of wood, plastic or builtup sections of cardboard or paper. The pleated material is originally in the form of a long strip with the pleats running transversely of the length of the material, and this elongated pleated material is wound around the hub a plurality of times, forming a cylinder, the hub being located transversely of this cylinder and centrally thereof.

A band 12 is then placed about the wound pleated material and is tightened up against the hub so that the pleated material is tightly and substantially permanently secured thereto.

The pleated material is then folded over the band l2 as is perhaps best seen in Fig. 3 where the folded over material is indicated at M and the sides thereof are then sewed together circularly and radially outwardly of the band [2 as at l6, thus compressing the folded over wraps of the material so that the same will appear as generally indicated in Fig. 2. This, of course, leaves a relatively round or semi-circular formation at I8 which is pressed against the periphery of the hub ID.

If desired, the buff is finished off by a cover sheet 20 and stitching l6 may, of course, go through the covering sheet as well as the folds of the wraps of the material.

As shown in Fig. 3, the hub It! may comprise a series of discs 22 which are less diameter than a pair of outermost discs 24 thus forming a recessed periphery for the hub, into which the rounded part 18 fits very nicely. This; provides a very strong construction even though the hub may be made of cardboard.

It will be seen that this invention provides a cuff which lends itself extremely well to highspeed production requiring very little handwork and, therefore, resulting in an improved bufi which is inexpensive to manufacture.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what we claim is:

l. A buff comprising a center hub, a plurality of wraps of pro-pleated material wound around the hub circumferentially thereof, the hub being at the center of the wrapped material, a band encompassing the wraps centrally thereof, and of the hub circumferentially of the latter, said band tightly pressing the pre-pleated material to the periphery of the hub, the wraps of material being folded over the band and extending radially outwardly from and in plane with the hub.

2. A buff comprising a center hub, a plurality of wraps of pleated bufling material arranged on the hub, and a flexible band or the like encom' passing all the wraps at the center thereof and holding the pleated buffing material in close engagement With the hub at the periphery of the latter, 'said 'hub being circumferentially recessed and the band holding the pleated material in folded over condition in the recess.

3. A buff comprising a hub, a plurality of wraps of pleated material wrapped around the hub circumferentially thereof, a tightly drawn band surrounding the wraps centrally thereof and firmly securing the latter to the hub at the periphery, and means holding the Wraps in folded condition over the band in plane with the hub, said hub being circumferentially recessed and the folds of the material forming a rounded edge tightly held 4 REFERENCES CITED The following references are of record inthe file of this patent:
