BANDAGE.

. Application filed July 3, 1919. Serial No. 308,388.

To all whom it may concern:

Be it known that I, DANA O. SEWALL, a citizen of the United States, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Bandages, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to bandages, sanitary napkins, and the like, and it aims to devise an article of this character which will have great absorptive properties, which can be economically manufactured, and which can be marketed in a convenient, compact and sanitary condition.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings and the novel features will be particularly pointed out in the .appended claim.

Referring now to the drawings,

Figure 1 is a plan view of a bandage strip made in accordance with this invention;

Fig. 2 is a cross sectional view on the line 22, Fig. 1; and Fig. 3 is a cross sectional view on the line 3- .3, Fig. 1. I

The bandage illustrated is in the form of a long strip, as shown in Fig. 1, and has a series of pads made of some absorbent material, such as absorbent cotton, gauze, or the like, enclosed therein and spaced apart at substantially uniform distances. The strip is made by folding a piece of fabric 2, preferably gauze. in a manner that will be obvious from an inspection of Figs. 2 and 3, to form a series of superposed folds, the edges of the folds being exposed at one edge only of the strip. The raw edges' of the gauze are turned inwardly, as indicated at, a, so that they are enclosed within the strip. The pads 4 also are enclosed within the strip, as clearly shown in Fig. 2, and preferably are located next to the outside layer of gauze atone side of the strip so that the difference in absorptive properties of the two sides of the strip, due to the fact that the pad is located closer to one face of the strip than the other, 'can'be utilized as desired.

It will readily be appreciated that the bandage strip illustrated can be manufactured very economically since the folding operations are very simple and can be performed automatically by very simple folding machinery. The folds can, for instance, be made by running the piece of gauze or other fabric from which the strip is made through stationary folding dies of a character well known to those familiar with wrapping and folding machinery, and the pads 4 can be inserted one at a time automatically at the proper point in the folding operation to enclose them in the manner illustrated. The invention thus provides a form of bandage strip which can be very economically manufactured in an entirely clean and sanitary manner and practically without hand labor.

For merchandising purposes a strip of the required length can be rolled up and placed in a suitable carton, or otherwise wrapped or packaged, to keep it in a clean and sanitary condition until it reaches the hands of the purchaser. In using the bandage strip it is unrolled and one or more bandages out therefrom by severing the strip at a point between the pads, the unused portion of the strip being kept rolled up.

What is claimed as new is:

A bandage of the character described, formed of a narrow strip of gauze, a series of pads of absorbent material arranged on one face of said gauze, the gauze being foldedinwardly over one edge of said pads and upon the face of the pads and then outwardly again, thegauze at the opposite edge of said pads being folded over the previous folds and then folded downwardly and inwardly again over said previous folds and then outwardly, the raw edges of the gauze being enclosed in the folded stripand unexposed.

In testimony whereof, I have signed my name to this specification.

DANA O. SEWALL.
