ABRASIVE PAPER. I f
Application filed January 4,- 1921.
.This invention relates to emery and other abrasive papers, and its object is to produce at a low cost an inexpensive flexiblefabrlc of this character.
To prepare the paper for receiving the abrasive material, it is rendered flexible and limp by preferably corrugating it long1tudinally and then crinkling it transversely, and then tentering the paper or pulling it or ironing it substantially smooth. The paper is then highly flexible or limp; and the abrasive material is applied thereto in a well-known manner. While I show the form of corrugated and crinkled paper that is disclosed in my application No, 333,750. filed October 27 1919, and while I also show this paper smoothed out as disclosed in my application, No. 407,399, filed September 1, 1920, still it will be understood that other forms and methods of corrugating and crinkling may be employed, and the gathered paper may be otherwise smoothed out.
Other features and advantages will hereinafter appear. I
In the accompanying drawings,
Figure 1 shdwsa section-of paper which has been first corrugated in one direction and then crinkled transversely.
Figure 2 shows a sheet of paper that has been smoothed out after being'gathered Figure 3 shows the Figure .2 product to the surface of which abrasive material has been applied 'to form a flexible emery or abrasive paper.
Figure 4 is a cross-section on line. 4-4 of Figure 3.
Figure 5 is upon which been applied.
The paper 10 has preferably longitudinal corrugations 11 and transverse crinkles 12, whereby it is rendered stretchable in all directions: but-the paper may be otherwisegathered transversely and longitudinally. This product, in which thefibres are limbered, is then stretched or smoothed out, and has the feeling of soft cloth. This ef-' feet is produced by the limbering and breaka diagram of a buffing wheel the flexible emery paper has ing up of the fibres by thegathering operations and the subsequent smoothing out' operation.
not so brittle as a stiff Serial No. 434,941.
To the surface of this material 13 there is applied an abrasive material 14:, thus producing a highly flexible abrasive fabric.
at low cost.
At Figure 5 is shown a buffing Wheel or drum 15 havingthe novel fabric Wrapped thereon. In the periphery of the wheel may be formed a V-shaped notch 15*, in which the ends 16 ofthe fabric are held by means of a wedge-like key 17.
The paper 13, since it is flexible and res'embles cloth, in its nature, remains flexible after the abrasive has been applied to one.
face thereof. This flexibility enables the abrasive paper to be bent easily and closely where required, as, for example, arounc' the buffing wheel. Paper of this nature it aper which has the abrasive material appii surface, nor does it so readily crack; and it lends itself readilyto be applied to various devices for sand-papering and other purposes.
Variations may be resorted to within the scope of the' invention, improvements may be used Without others. Having thus described my invention, I claim:
1. The process of gathering paper in transverse directions to limberthe fibres thereof, then smoothing out the paper, whereby it is rendered flexible, and then applying an abrasive material to thesurface thereof to produce a flexible or limp abrasive sheet.
e 2. An abrasive paper turbed, loosened. and limbered to" increase its flexibility, the paper being relatively flat, and a substantially unbroken coating 0 ed to its smooth and portions of the having its fibres disabrasive material applied to 'at least one surface ofjsaid paper;
3. An abrasive paper comprising paper M having its surface fibres-on op osite sides broken or distorted while the middle fibres are less disturbed, said paper being relative- WILLIAM A. LORENZ.
