PAPER WADDING Filed NOV. 23, 1931 Patented Feb. 26, 193,5 Y l PATENT OFFICE PAPER WADDING William n.- Kellett, Menasha', Wis.,
assigner to Paper Patents Company, Neenah, Wis., a. corporation of Wisconsin lApplication November 23, 1931Serial No. 576,955 4 Claims. (Cl. 154-64)v My invention relates topaper wadding, and contemplates more particularly an improved fluffy Wadding formed of a plurality of plies of relatively thin paper, such as creped tissue paper or the like.
An object of my invention is to provide material of the type referred to in which the sheets are secured together without any sacrifice to the fluiness and lightness of the Wadding.
A further object is to provide a waterproof or non-absorbent wadding of the type referred to.
Various other objects and advantages will become apparent as the description proceeds.
The accompanying drawing forms a part of this specification andillustrates a preferred embodiment of my invention.
In the ordinary manufacture of crepe-paper wadding, the tissuev paper is removed from the drier by means of a doctor blade and drawn inan 20 endless web to a reel where it is wound up to the desired thickness. The mat thus formed is then cut longitudinally of the reel and the blanket thus obtained is drawn o" and cut into a plurality of strips of the desired width. p
-Such wadding is used for a large number of purposes, for example, as padding in upholstering automobile seats, furniture, and, the like. -When so used, it has been customary in the past to compress or emboss the padding, but, as a result, the enclosing fabric has been caused to wrinkle and produce an unsightly article. While attempts have been made heretofore to apply adhesive to the tissue sheets, this practice has resulted in a. loss of iiufiness, consequently of bulk, in'the wadding, due to the large amount of water and adhesive which it has been considered necessary to use. Therefore, such material has fallen far short of the uff resilient padding which one might hope to obtain, in view of the initial material.
In'accordance with my invention, liquid adhesive is applied to'one surface of the creped tissue sheet or web in a plurality of relatively minute and spaced droplets 12 before it is wound upon 45 the reel to from a blanket. The adhesive may be of any suitable type and of any desired viscosity. My preferred adhesive solution -is one made from starch hydrolized with caustic soda with the addition of a small quantity of sodium fluoride so as to prevent its being eaten by mice or insects. The process otherwise may be similar to thatde'scribed above. I preferably use a very thin grade of crepedtissue paper. It will be obvious that, as the web is rolled upon itself on the reel, the layers of tissue paper will adhere to each y of consisting of loose sheets,
other by reason of the presence of adhesive. Hence, when the material is cut and removed from the reel, the blanket or wadding W, instead will be substantially integral. y 5
One manner of .applying the adhesive to the paper sheet or web is by picking up a quantity of liquid adhesive on a brush or the like and then iiinging it onto the sheet. The adhesive will thus spatter onto the sheet in a plurality of spaced l0 droplets.
An important advantage of my improved process is that no further additional drying step is required after applying the adhesive. On the other hand, where adhesive'is applied in other 15 ways, the material must be subjected to a special drying operation because of the large amount of liquid carrying the adhesive. This, of course,- necessitates additional time and fuel and the-use of apparatus, thus raising the cost of production.
- A preferred form of my invention has to d0 with the preparation of an improved material which may be used in various relations, particularly in the packing of goods for shipment, where fluiness and moisture insulation are desired. It
is highly desirable that such insulating material be substantially non-moisture-absorbent, especially where the insulating material is formed of tissue sheets as in the present case, since such material loses itsfluffy nature to alarge extent in the presence of moisture, and thus largely loses its value as packing. Hence, moisture insulation is an important requisite in ypacking goods for Water transportation.
In the manufacture of my improved insulating material, I treat the bers in such a manner as l to render the resultant paper water repellent. I prepare a stock as in the usual preparation of creped tissue paper, preferably using sulphite bers or a mixture of groundwood and sulphite. Various substances may be employed to render the fibers water repellent, but I prefer to use a rosin size, which I preferably apply as a rosin suspension in rosin soap (a lcommon size) and aluminum sulphate (the usual papermakers alum). I preferably introduce these substances in the beater in the manner usually practiced by papermakers'in sizing paper, but they may be applied at other stages of the process, as in the Jordan engine.
I proceed with the manufacture of a; very thin creped tissue paper sheet 10 in the usual manner, which is well-known to those skilled in the art, and then may apply adhesive thereto in ne spaced droplets 12,' in the manner described above, 55
to form a wadding W consisting of a plurality of sheets of sized creped tissue paper secured together by the spaced droplets 12 of adhesive.
The material thus formed is excellently adapted for use as packing, and is of particular advantage because of its extreme. lightness. The very small quantity o! adhesive used naturally adds little to the weight ofv the material. The
wedding lends itself advantageously to the pack- ,ing of materials for water transportation, since within the spirit o! my invention will doubtless `naaf/2,2115
suggest themselves to those 4skilled in the art. Hence, I do not wish to be restricted to the specic embodiments disclosed herein or uses mentioned, except to the extent indicated by the appended claims, which are to be interpreted as broadly as the state of the art will permit.
I claim as my invention;
1. Stuillng wadding comprising a plurality of superimposed sheets of creped woodpulp tissue paper'sized to render the same moisture-repellent and secured together by means of' adhesive disposed on said sheets in a plurality of spaced droplets to form a iiuifymat.
2. A material as dened in claim l, wherein the paper comprises sulphite ber.
3. A material as dened in claim 1, wherein the paper comprises a mixture of sulphite and ground wood iiber. f 4. A material as dened in claim 1, wherein the 4material has been rendered moisture-repellent by means of a rosin size.
