To all whom it may concern.-

Be it known that I, EJNAR FABRICIUS- B-JERRE, citizen of the Kingdom of Denmark, and residing at Frederiksberg, near Copenhagen, Denmark, have invented certain new and useful Improvements in Absorbent Pads, of which the following is a specification.

This invention relates to the of a liquid-absorbing gauzelike from a known fibrous or cellular material, say cellulose wadding, peat fibres, felt, waste sponges, or the like which is covered on one or both sides by crossing threads forming a gauze-like surface and entering into an inseparable connection with the fibrous material so that the latter cannot during its use be decomposed by soaking or otherwise.

The fibrous material may be treated in av known manner in different ways, that is Iproduction -it may be sterilized, freed from grease in order to increase its absorbing ability, or weakened by mechanical or .chemicaltreat- The material must be such be mechanically manufactured, that is, the fibrous or cellular mass is at first in the way known from the manufacture of paper or by spinning machines formed into an endless belt of a suitable width and thickness, and, thereafter,-rolled or folded together so as to give the ready material its proper shape and thickness. Further the material is sewed by crossing threads in a special machine so as to produce the above mentioned gauze-like covering, and subsequently cut or stamped out to obtain a shape corresponding to the purpose in question. Finally it is provided with sewed or bound straps, bands or the like in order to enable it to be secured, and it is then ready for use.

The above mentioned various mechanical treatments of the material may be carried out in one single machine, or the material may pass several machines each performing one of said treatments. v

The invention is clearly illustrated in the accompanying drawing, in which Fig. 1 is a top plan view of a portion of the material,

Fig. 2 is the bottom plan view thereof,

Fig. 3 is a transverse section through the material, and

brous pad separately y the stitching is made in such a that it may Fig. 4 is a transverse section through a modified form of the invention employing twolayers of the material one of which is water-proof.

Referring now, more particularly, to the accompanying drawing there is provided-a pad a of fibrous material through which threads I) are drawn so as to form on the engaging surfaces a auze-like covering inconnecte with the material.

Preferab manner that rows of chain stitches are laid in one direction and loose threads are arranged below and engaged b said stitches on the engaging surfaces 0 the material and preferably intersecting said chain stitches at right angles so as to form substantial squares as indicated in the drawlngs.

In Fig. 4 there isshown a slightly modified arrangement com rising superposed. layers a and a", the ayers being of an absorbent nature while the layer a is impre nated in a'known manner so as to be ren ered water-proof, the purpose being to prevent the liquld absorbed by the layer a from penetrating through the layer .a". The threads 6' are arranged in the same manner as described in connection with Figs. 1 and 2 being of course passed through both of said layers so as to hold them together. The ads, as intimated, are provided with a binding or band 0 along the marginal edges so as to prevent the material from fraying at said edges.

The fibrous material treated 'as above is intended for use in the sick nursing as dressing, operating serviettes, catamenial sacks, childsnapkins', breast napkins for nursing ladies, towels, handkerchiefs, and in the general in all cases where a great absorbing ability is important.

After the use the gauze-like fibrous material is discarded which is an invaluable advantage in hygienic respect. As the fibrous material may be delivered in a sterile state, it will be preferred in many cases to other materials used hitherto.

A special employment of the materialis for childs napkins. Experience has shown that a childs napkin, of this gauz'e-like fibrous material having a lesser weight than a napkin of the best suited materials hitherto known is as ood as two such napkins.

Having thus 11y described the inveneluding a pad-like bod tion what is claimed as new and desired to thickness, and a gauze-like covering of cross threads arranged on one side only of the pad-like body with threads of the coverin entering intoan inseparable connection wlth the pad-1ike.body.

2. A pad of the character described formed of a layer of an absorbent fibrous material of suitable shape and thickness, a waterproof layer of fibrous material arranged adj aoent one surface of the absorbent threads arranged on one face only of the absorbent layer with threads'of the covering entering into an inseparable connection with the layers so as to hold them together.

substantially as and for the purposes set forth.

3. A device as claimed in claim 1, wherein bindings are secured to certain edges of the pad-like body to prevent unraveling and frayin of the material at said edges, substantia ly as and for the purposes set forth.

In testimony whereof I afiix my signature.
