To all whom it may concern.-

Beit known that I, HENRY A. FRAMBACH, a

citizen of the United States, and a resident of after described and then pointed claims.

Kaukauna, in the county of Outagam'ie and State of YVisconsin, have invented an Improved Machine for Applying Gum or Glue to the Surface of a Web of Paper, of which the following is a specification.

This invention relates to machinery for ap-.

plying gum'or glue to the surface of a web of paper, and relates particularly to machinery for so applying gum or glue to a web of paper which is designed and intended to be cut into tie-bands for usein laundries for securing shirts in folded position.

H eretofore the general practice has been to apply gum or glue to tie-bands by hand after the web of paper has been cut or severed into bands, it having been found practically impossible to apply gum or glue thereto by machinery while united in a web, owing principally to the diificulty of distributing such gum or glue evenly upon the surface of said web, a thick strip of gum or glue forming across the web where the gumming or gluing device leaves'said web. Owing also to the consist,

ency of said gum or glue, it stretchesout in the form of strings, which are apt to adhere.

to the surface of the paper outside of the portions thereof which it is desired to gum or glue in an undesirable and objectionable manner.

The object of myinvention is to provide improved means to apply gum or glue evenly to desired portions of the surface of aweb of paper of limited areas, which said gummed or glued portions of said web of paper shall be separated from each other by unguinmed spaces of uniform length.

A mach ine embodying my invention consists of the various features, combinations of features, and details of constructionhereinout in the In the accompanying drawings a machine embodying my invention vis fully illustrated.

Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a vertical longitudinal sectionalview thereof. liig. 3 is a transverse sectional view thereof, on the line 3 3 of Fig. 2, lookingin the direction indicated by the arrows; and Fig. 4 is a plan view of a web of paperto which gum or glue has been applied-by means of my improved machine, the 'gummed areas being indicated by the shaded portions thereof and the method of severing the saine to form individual bands being indicated by dotted lines.

As shown in the drawings, the operative parts of my improved machine are supported in a frame which consists-of lateral frame-sections A, secured together by transverse frame members A. 7 Revolubly mounted in suitable bearings formed in the lateral sections A of the machine-frame is aroll B, the under side of which runs in a gum or glue fount B, the bottom I) of which is hollow, and-the interior of said hollow bottom being connected with a suitable source of steam-supply by a pipe 22, through which steam is admitted thereto. The steam so admittedsto the hollow bottom 12 of said gum or glue fount will operate to maintain the gum or glue therein in a liquid state and likewise affords convenient means for regulating the consistency thereof.

Secured to a shaft 19 revolubl y mountedin suitable bearings in the machine-frame above the roll B, is a segment of a cylinder E the circumferential dimension of which is equal to the desired width'of the gummed or glued .areas on the web of paper.

The shaft 12 is so located relatively to the roll B that as said shaft rotates the perimeter of the cylindrical segment 13 will come into contact with the perimeter of said roll B.

Positive rotary movement in the directions indicated by the arrows is imparted to said roll B and to the shaft Z1 by suitable means.

Asshown, the roll B is driven from anysuitable source of power (not shown) by means of a belt applied to adriving-pulley B rigidly secured to the shaft of said roll, and the shaft 17 1s driven from the shaft of the roll 13 by means of spur-gears b b", secured to the shaft of the roll B and to the shaft respectively, the sizes of said gears being such that the segmental cylinder 13 will be driven at the same surface speed as the roll ll. Preferably, also, the roll 13 is driven through the medium of a clutch, which affords convenient means for starting and stopping the same.

Revolubly mounted in suitable bearings eter of said roll B.

Positive rotary movinent in the direction indicated by the arrow'is. imparted to the roll provided with sleeves Z1 at B by means of a spur gear 11 secured to the shaft. thereof, which mesh s-withthegeanb? on the'shaft b the size-thereof being such that said roll Btwill be driven at the same surface speed as said segmental cylinder B Supported above the segmental cy-linderB in such manner" as to be bodily movable toward and from the same is a scraper or doctor B .As shown, said scraper or doctor is which are fitted to studs 12 rigidly secured in the machine-frame. Threaded to-the studs b are nuts 6 between which and the tops of the sleeves bare inserted coiled springs 19?, which I operate in an obvious manner to hold the scraper or doctor B normally yieldingly advanced, in which position the lower edge of said scraper or. doctor extends below the surface of said segmental cylinder B proved machine also comprises means to raise said scraper or doctor intermittently to allow 'lar cams B scraper or doctor 13 'will be said segmental cylinder to pass under it and to release said scraper or doctor-just before said segmental cylinder passes from beneathit, allowing said-scraper or doctor to'des'eend into contact with the surface of said segmental cylinder at a point adjacent to its rear edge, thus severing any strings of gum or glue which may have vformed between said segmental cylinder and the roll B and scraping any superfluous gum .or glue from the rear edge'of said segmental cylinder. said means are as follows: Secured to the shaft b adjacent to its opposite ends are simiupon which the scraper or doctor B is normally supported. -Said cams-B are of such size and shape and are secured to the shaft 1) in such position that as said shaft 12 rotates they will raise said scraper or doctor above and out of the path of travel of the segmental cylinder B, allowing said segmental cylinder to pass fl'eely beneath the same. Said cams are also cut away,substantially as shown at 11 in such manner that said will he suddenly released just before said segmental cylinder B passes from beneath it, thus allowing said scraper or doctor to descend under the influence of the springs b into contact with the surface of said segmental cylinder adjacent to its rear edge in the desired-manner.

The lower edge of the scraper or doctor is preferably beveled or a blunt chisel edge about one eighth of an inch thick. I find in practiceithat a scraper or doctor of this shape is best adapted to perform the desired function thereof.

The gum or glue is applied to the web of paper by the segmental cylinder 3, which of such size that the periphery of the its opposite ends,

its front side, leaving supply'in substantially the same manner that steam is admitted to the drier-rolls of a paper-making machine, which will be clearly understood by persons familiar with such machinery without a detailed description thereof. Rotary movement in the direction indi cated by the arrow is imparted to the drier C by means of a chain-belt G, applied to sprocketj wheels 0 C secured to the shaft of the roll and to one of the trunnions of the driercylinder 0, respectively, the relative sizes of said sproeketwheels being suchthat the surface speed of said drying-cylinder C will be the same as that of the other positively-driven drums and rolls over which the web of paper passes.

i to from a roll D, supported in suitable bracketbearings formed on the machine-frame, Said 1 roll is preferably provided with a suitable friction-brake to retard its rotation and mainlovsuand is connected. with .a sourcehofsteam-r Paper to feed the machine is supplied theretaintheweb ofpapertantas itis drawn theref from in afamiliar manner.

In the drawings, D, designates the web of paper in which the machine is operating.

Fig. 4 of the drawings represents a portion of a web of. paper af er passing through my j improved machine, the darkened or shaded portions 01 indicating those parts to which the gum or glue has been applied. Separate bands gummed or glued at one end only are formed by slitting the web D on longitudinal lines d and severing it on transverse lines d The operation of my improved gumming or gluing machine is as follows: The web of paper D is delivered from the roll of paper D around guiderolls d into contact with the surface of the roll 13*, so that the segmental cylinder B will come into contact therewith as th'e shaft Z1 rotates. Fromthe roll B the Web D passes around the drying-cylinder C, whencei-t is conducted over guide-rollers (l to asuitable reel. (Not shown.)
