' Our present'invention relates to an imroved sticker band intended particularly or use in a photographic roll film cartridge. Roll film cartri gee of a common type m- 6 'clude lon strips of interwound backing "paper an film, the latter being secured at one end by a sticker to the paper, and the other end being free but havin a sticker attached. There have been mar et'ed such m films in which the adhesive of the first men- ;tioned stickers was water-proctor unaflfected by water, the use of such stickers renderible the rapid assembly of the cartri ge withoutthe possible introduction of moisture at this point. It has notbeen possible, however, to utilize this t e of sticker at the free end of the film for t e reason that the permanently tacky adhesive will at once adhere to the backing to use" a sticker with a water-soluble a hesive, such'as glue, at this free end of the film. The use of such a sticker necessitated the dampening of the end thereof which was .to be attached to the film and involved certain disadvantages.

' We have tended particularly for use at-the free or un- I attache end of the film which overcomes 'these disadvantages in the process of making the cartridge and which further'improves the cartridge as a photographic article. It com- Lprisesa sticker carrying an adhesive capable of bei afiected by water by which it may .be attac ed to the paper when desired, but

carrying also a'portion coated with a permanent y tacky adhesive bywhich it may be applied to the film without the application 0 water; and thus permitting the ll glinding'of all the elements in a. dry con- 'tion.

' This' ap lication is a division of our application Serial No. 563,447.-filed May 24, which matured into Patent No. 1,500,393,

Our preferred form of sticker 7 comprisesa rectangular strip, as shown in Fi 3, along one border of which is coated a and 8 of permanently tacky adhesive material unaffected by water, and alon gthe opposite border of which is coated a and 9 of glueor other water-soluble adhesive,leaving an uncoa'ted intermediate-fportion'lt).

In the process 0 making a cartridge a spool 1 is laced in suitable winding means, such as spindles-11, 12, which may be adapted for rotation by any desirable" mechanism, either hand actuated or automatic, a machine for o crating such spindles 'beingedisclosed in t e nding application rial No. 516,229, fi ed Nov. 18, 1921,-of Jones, one of the present inventors." The end of a stri Yoax, assrenoas ro which is preferably perof backing paper 2 is attached to the spoo which is then turned in cated by the arrowuntil is wound thereon.

pressed into firm contact with the film and then preferably permitted to dry If too much water is used, either too great an amount of moisture will be carried into the cartridge or an undesirable delay will. be necessary. If too little water is used the sticker will not adhere firmly. Moreover, while the stickers may be positioned by automatic machinery, they are in practice placed by hand; and it is customary for the operator to ress the sticker into adhesive contact wit the fingers. If this is not uniformly done over the surface, some parts will not be stuck, especially if too little water has been used. As the adhesive dries rapidly, its adherent qualities decrease. All of these difliculties are overcome by the permanently tacky adhesive; no water is carried into the cartridge; no delay is desirable; and when the sticker is properly positioned on the film and carried into the roll, it will be pressed into firm adhesive contact by the pressure of the tight winding.

It is obvious that the cartridge as a photographic article is improved, since the possibility of the presence of undesirable moisture is greatly reduced.

It is apparent that numerous modifications may be made in the form of the sticker and we have chosen certain of the more d'esirable ones for pur oses of illustration.

The two adhesive ands need not be so arated by an intermediate uncoated portion and forms illustrative of this are shown in Figs. 5 and 6. In Fig. 5 the two coatin 14 and 15, of waterproof and water-soluEl e adhesives respectively are extended from the borders of the supporting strip 16 to meet at an intermediate oint 17, leaving no uncoated portion. In Ii 18, preferably of paper, is uniformly coated with one type of adhesive 19, and upon this is adhesive secured a smaller strip 20, with the other type of adhesive 21, this forming a sticker having portions of each type. This type ofl'ers certain manufacturing advantages. v

It is not necessary that the two adhesive surface of the sticker strip. In Fig, 4 is shown a strip 22 having on one surface a border 23 of which it is attached to the end 6' of the 3, and on the other surface and near the opposite edge a border 25 of dry water-soluble adhesive,

The adhesive which wedescribed .as waterproof or permanently tacky, is of a well known type such as is used for adhesive tapes of various kinds. A typical composition includes rubber and-coal tar pitch with any suitable softener such as benzol, gasoline or chloroform. We do not limit ourselves to any particular composition since any 'adhesive that is so slow drying as to' maintain its tackiness over a reasonable time, and the adhesive properties of which are unaffected by water is contemplated as within the scope of our invention. Similarly when we refer to water-soluble adhesive, we intend to include any glue or paste which usually dries quickly and which becomes quickly adhesivein the'presence of moisture. I I

It is ap arent that while the sticker band is particu arly adapted for the uses herein described, it is capable of other uses, and particularl for 'use as the sealin band that is supplied at the tail end of t e backing paper as sold by the manufacturer. We contemplate aswithin the scope of our invention all such modifications and equivalents'as fall within the following claims.

Having thus described. our invention, what we claim as new and desire to secure by Letters Patent is:

1. A sticker for use in roll film cartridges comprising a strip of flexible material having along one edge a band ofadhesive capable of bein affected by water and along the opposite e ge a band of water proof adhethe permanently adhesive type by 2. A sticker for use a. roll film cartridges comprising a strip of flexible material having separated bands of adhesive material thereon, one of said bands being of waterproof material and the other of material capable of being affected by water.

3. A sticker band comprising a rectangular strip of paper having one surface and border thereof a coatin of adhesive material capable of water and on the same surface and alon the opposite border a coating of waterproo ad- S gned at Rochester,
