Oct. 1, 1929. H. M. BRIGHTMAN BANDAGE ROLL Filed May 4, 1926 Patented Get. 1, 1929 HENRY M. BRIGI-ITMAN, OF BRADFORD, RHODE ISLAND, ASSIGNOR TO HYGIENIC FIBER COMPANY, INCORPORATED, OF VEBSAILLES, CONNECTICUT, A CORPORATION OF MASSACHUSETTS BANDAGE ROLL Application filed May 4,

My invention relates to so-called gauze bandages and particularly to a package or method of storing and dispensing the same.

One of the objects is to provide a sanitary roll which can be readily broken up into short lengths. Another object is to provide .abandage sheet in such a roll form that. it

may be readily broken into short lengths without leaving troublesome frayed ends or ravellings. Another object is to provide a convenient method of packaging and dispensing gauze bandage sheets.

In carrying out the invention the cloth, which is usually called gauze, is passed through rolls which weaken the weft threads at intervals along zig zag lines. The sheet is then tightly rolled or wound up into a roll. The roll is then wrapped in a suitable protective cover for instance of paper and sealed for shipment. The roll with this enveloping wrapper is adapted to be broken on the planes in which the weakened sections have been wound.

Fig. 1 is a perspective view of a bandage roll embodying my invention with one end broken off.

Fig. 2 shows a fragment of the gauze fab- I ric on an enlarged scale showing the line of weakening of the weft threads.

Fig. 3 is a still larger fragmentary View showing one method of weakening the weft threads along a zig zag line.

The gauze comm-only employed for surgical bandage purposes is woven and consists of warp threads 5 with weft threads 6 inter woven therewith, the gauze being usually of cotton or linen.

The sheet of gauze is first passed through suitable instruments such as cutting or fracturing rolls with teeth or edges arranged on zig zag lines and adapted to crush the fiber of the weft threads along a zig zag line as indicated at 7 in Fig. 2. The appearance of the crushed weft threads is indicated at 8 and 9 on the very much enlarged fragment of fabric shown in Fig. 3. Preferably this weakening does not entirely sever the weft threads but weakens them so that they can be readily broken along a zig zag line. After the weft threads have been thus weakened 1926. Serial No. 108,604.

the sheet is rolled up tightly into a roll 10, the weft threads running longitudinally of the roll. The roll is therefore quite weak along the planes of the weakened sections as at 11 in Fig. 1. As the sheet as a whole has not been severed or broken up by the weakening action the roll requires no core or other interior stiffening means for holding the roll together.

After the roll has: been made as above de scribed it is. wrapped in paper or other suitable material 12 which may be sealed so as to keep dirt and other contaminating matter from cont-act with the gauze. The paper with which the roll is wrapped is preferably stronger in one direction than in the other, and preferably it is weakest in the direction of the length of the roll so as to facilitate breaking the roll into sections constituting the individual bandages 14.

The package may be marked at the sections 11 11 where the roll is breakable so as to facilitate the separation and also so as to indicate visually the width of the bandage in the roll. The roll may also be provided with a label or tag 15 containing on it a statement of the width of the roll, the length of the sheet and also the width the individual sections will have when the roll is broken.

This method is a particularly convenient one for handling and rolling the gauze sheet and is much cheaper and produces more uniform results than is possible where the bandage tapes are first cut and then wound up separately and assembled in a roll. The weakening along the zig zag lines also greatly improves the product as it lessens the likelihood of line lint clinging to the bandage which lint is quite objectionable and likely to get into wounds.

It should be understood, of course that the sheet may be of any desired'width and that it may be scored or weakened along any number of lines at any desired spacing so as to produce a bandage roll of any suitable length designed to be broken up into individual bandage rolls of any desired width.

I claim:

1. A bandage roll comprising a sheet of gauze having its weft threads connected but weakened at intervals along zig zag lines, said gauze sheet being wound tightly into a single roll and a paper wrapper enclosing said gauze roll, said roll and Wrapper being breakable at the planes of said zig zag lines.

2. The method ofpackaging bandage rolls which comprises first crushing the weft threads of a sheet of gauze along zig zag lines to Weaken them without separating them, then tightly rolling up said sheet into a single roll in which the zigzag lines overlap and form prospective roll sections separable from each other by breaking the roll on the planes of the weakened lines.

3. A gauze bandage roll comprising a single sheet of Woven gauze wound tightly into a single roll, weft threads of said sheet being crushed and partially severed and materially weakened along an irregular zig-zag line extending longitudinallyof the sheet and said sheet being wound so that the irregular weakened portions are arranged in a general transverse plane and a protecting Wrapper for said roll, said roll and wrapper being readily breakable at the plane of the weakened por tion.

HENRY M. BRIGHTMAN.
