PROCESS OF MAKING S TRETCHABLE PAPER.

SPECIFICATION forming part of Letters Patent No. 790,021,"dated May 16, 1905. Application fil d December 21,1901. Serial No. 86,829.

To aZZ whom it may concern:

Be it known that 1, JAMES ARKELL, a citizen of the United States, and a resident of Canajoharie, in the county of Montgomery and State of New York, have invented a certain.

new and useful Process of Making Stretchable'Paper such as is Suitable for Wrapping or Packing Purposes, of which the following is a specification.

This invention relates to a process for making stretchable paper of comparatively durable grade, such as will be suitable for Wrapping or packing purposes.

The invention seeks to provide a paper of the grade stated that shall be capable of withstanding strains such as may be put upon it when in use and which wrapping or packing paper as heretofore made is not capable of enduring without breaking. This purpose is accomplished in accordance with the present I invention by forming inthe paper fine, deep, and tight creases or crinkles, which enable the paper to stretch when under strain, so that the paper does not break. 7

In carrying out the invention I start with a suitablefinished paper, which when crinkled will be adapted for use as a wrapping or packing paper. This paper is then passed through a saturating-bath of suitable liquid, such as Water, whereby the paper is thoroughly saturated. The wet paper is then deposited upon a smooth-surfaced roller, to which it is made closely to adhere, and is carried by said roller against an obstruction, such as a doctor-blade.

This obstruction or doctor-blade crowds the wet paper back against itself, and thereby forms crinkles in the paper, which is thereafter removed and dried, so that the crinkles become permanent in the paper and render the paper stretchable.

Prior to this invention there hasbeen no way of increasing the resistance of the heavier grades of paper to strains except by using a better and more expensive quality of paperstock or by using a greater amount of paperstock and making thus a thicker heavier paper. In such cases, however, the paper is substantially if not absolutely unyielding and non-stretchable, and is therefore liable to rupis done without employing a better quality of paper-stock or more paper-stock. In fact,

the invention makes it possible to start with 7 paper made from paper-stock of poorer quality or less in quantity, or both, and yet obtain a resulting product.-that is,'crinkled wrapping V or packing paperwhich is far superior to uncrinkled paper when made out of paper-stock better in quality and greater in amount.

The process is most conveniently carried out in connection with an apparatus shown in the accompanying drawings, which form a part of this specification. This apparatus will now be described, and in connection therewith the process will be more fully set forth in detail. I

Figure 1 is a central vertical sectional elevation .of such apparatus. Fig. 2 is a sectional elevation of the same, taken on the line 2 2 of Fig. 1.

The paper 1 in the form of a web is most conveniently taken from a roll and carried thence through a saturatingbath 2. In passing through this bath 2 the paper is most conveniently carried on a perforated roller 3, which depresses the paper into the loath and allows thorough access of the water to the paper. After emerging from the bath the paper is deposited upon a smooth-surfaced roller 4, against which it is made to closely adhere by the roller 7 rotating in contactwith the roller 4. The roller 4 'is preferably made of iron or other metal, and the roller 7 is preferably covered with rubber. As the paper moves forward with the roller f it comes in contact with the doctor 5, which strips the paper from the roller' i and at the same time crowds the paper back against itself, and so forms the crinkles in the paper. The paper is then carried away by the belt 6 and dried, so as to make permanent the crinkles formed in the paper, and thereby render the paper elastic or stretchable. The roller 7 serves to press the paper close upon the roller 4, so as to make it closely adhere to the roller with suchtenacity as will enable the doctor to crowd the paper back against itself, and thereby crinkle it. 7 It also serves to remove the surplus moisture in the paper. It is important that the paper contain the right amount of moisture before it reaches the doctor 5. If there is either too much moisture or too little moisture, the crinkles will not be properly formed in the paper by the doctor. It is also important that the wet paper be pressed in sufficiently close adherence to the roller 4 to enable the doctor to form the crinkles in the paper. For the purpose of regulating this moisture and this pressure the roller 7 is made adjustable to and from the roller4 by means of hand-wheels, one of which is the wheel 8. Of course it is not essential to the process that the surplus moisture be removed from the paper at the same time the Wet paper is pressed in close adherence to the roller 4; butit is preferable to accomplish these steps at the same time and by the same agency. As the paper emerges from the bath 2 it is liable to have longitudinal wrinkles therein, caused by the expansion of the paper, due to the moisture absorbed. For the purpose of removing these wrinkles the wet paper is extended laterally at some stage before it reaches the doctor 5. This lateral extension of the paper is preferably accomplished before the paper is deposited upon the roller 4. The means which I find eflicient for this purpose consists of one or more curved bars or rods over which the paper is passed. In the apparatus shown in the drawings two of these bars 9 and 10 are shown. They serve to efficiently smooth out the paper by extending it laterally, and so remove the wrinkles.

11 and 12 are two hand-wheels for adjusting the iron roller 13, which guides the paper on to the roller 4 and which adjusts its tension.

I generally prefer to rotate the roller 4 within a second bath 14, thereby insuring an elficient saturation of the paper when the latter is made to move swiftly through the apparatus. In place of the bath 14 other means may be used for wetting the paper while on the roller 4.

Various changes in the several steps of the process and in their sequence may be made without departing from the scope of the in Vention.
