Be it known that I, EDWIN W. a citizen of the United States, and a. resident of the city of East Orange, in the county of E'ssex and State of New Jersey, have inve'nted certain new and useful Improvements in Methods of Making Flying Pasters, of whichthe following is a specification, reference being had to the accompanying drawings forming part thereof.

In high speed presses, particularly those used 'in the printing of newspapers, it is desirable that the web of paper supplied to the press shall be handled in such a manner as to minimize stoppages of the press and interruption in the supnlying of the paper due to breakage of the web, exhausting of a roll of paper, or other causes. As is well known, the rolls of paper used in such presses each weigh about a ton and the web of paper is-supplied to the press at the rate i of twelve hundred feet a minute, or thereabouts.

It is the present practice, and has been for many years, to secure continuity of supply of web-paper to the press by making what is known as a flyingpaster. In other from the active roll which has been supplying paper to the press, 'the press'. is slowed down and the end of the'web of afresh roll, which has'had an adhesive vapplied to it, is attached to the web going to press from the depleted roll and after this adheion takes place the old web is severed and the new web runs to press which is then brought to full running speed. i

The making of such a flying paster has involved the usetof a rotatable roll stand and traveling belt therefor, in the general' `manner described 'in Stone Patent No'.

ture of successful printing press equipments, i being depended 'upon to feed the paper to the 'press and' to control the movements of the roll of paper against which it pressed and with which it cooperated. The theory' of operation for normal running and for'the making of a flying paster is described in the above mentioned Stone patent, I have dis. i

covered, however, another method of making a flying paster, making possible' the employment of simpler and less "expensive appara-- Hanna,

simplified apparatus is set fort in the ac-' companying drawings in which Fig. 1, shows an end elevation of a roll stand adapted for employment in carryin out my improved method; Fig. 2, is 'ai sde elevation of the same as'viewed from the right. 'Fig. 3 is an end view in partial section of a simple form of hand brake for use on the roll stand; Fig. 4, is a side' elevationin' partia'l section of such hand brake applied to the roll stand; Fig. 5, is an end view of the roll stand with the flying'paster in process of being made, and Fig. 6, another-view of the same with the flying paster completed and the new roll serving as the source of paper supply for the press. v i

- Referring particularly to Fig. 1, it will be seen that the roll standis of the conventional form comprising supporting stand ards 1, carrying the spiders mounted upon a shaft 2, and having arms`3 adapted to serve as a magazine support for 3 rolls ofweb-paper, the rotation of each roll being controlled by a suitable brake as indicated at *10. In this figure the web of paper is shown as coming from the nearly vdepleted roll 4 the position ;of a hand breke 10 is indicated,

located between the duplicate' arms of the spider 'at one end of the roll stand; if deat the other end: also. i The preferred con- -struction of thehand breke-is llustrated m Figs 3. and 4, in which the arms 3, 3 are corresponding arm'sto'f the duplexspiders at oneend 'of the :roll stand the breke being- 'applied to the spindle -11, designed to 000.11- `erate with' one end of the heavy roll ofpa r, Such spindle 11 carries an enlarged ub 11 around which passes a'brake-band over the rollers 8 and 9, to the press. In Fig.

si -ed, a similar hand brake might be applied ,12,'s upported at one en'd'from the fixed point 14 and having its 'otherend adjustably controlled through the hand wheel 10, the internal screw threaded shank 15, and the threaded. extension 16 se'cured to the brake-band 12. The fixed support 14: is a barspanning the gap between the two arms 3-, 3, as clearly shown in 'Fig. 4, being fixedly Secured to such arms. v In making a flying paster in 'accordance with my method, the procedure is as follows: The press is brought to a proper speed and the tension Secured by the handbrake 10 is adjusted to maintain a taut web running from the depleted roll; the operator causes the spider of the roll stand to slowly revolve, advancing the new roll 5 to ward the outwardly runnin web 7 until contact is efi'ected between te new roll 5 and the expiring web 7 at a point where, as will be seen, there is no physical hacking supplementing the tautness of the web; in anticipation of this advance of the new roll, the operator has turned such roll on its spindle so that when contact is made with the outgoing web 7, there will be sufiicient time for the new roll to begin turning before the gummed edge comes in contact with the outgoing web 7 the combined efi'ect of the taut web running to press and the slow advancing of the roll 5 is to bring sufiicient pressure upon the roll 5 as to cause such roll to turn spindle to bring the gummed end of the-new web into contact with the expiring web, adhering thereto and traveling to the press with the expiring web from the old roll 4; this takes place with the old web considerably bulged out, as illustrated in Fig. 5; there being nothing behind the web to serve as a backng for the web; when the new web has adhered to the old web and both webs arie running to press, the old web is severed; below the roll 5, as at X, and the press may then be brought to fulltrinning speed, the new roll 5 thus having taken the place of the depleted roll 4 which may' thereupon be removed and a fresh roll substituted for it so as to maintain the supply of spare rolls of paper.

It is thus seen that I have discovered a mode of making a flying paster without the use of -friction belts or other power driven devices for turning and controlling the active web roll, the web thereof thus-being fed to .press solely by the pull of the press itself. u

I claim as my invention 'the following:

1. The method of makinga fl ing paster of a fresh 'roll of. web paper to t e expiring web from' a depleted roll being fed to press solely by the pull of the press itself comprising the use of a rotatable supporting means for a plurality of rolls and means for rotating the same so as to bring vancement of a fresh roll into contact with the expiring web at a point where such web has no supplementary hacking, the setting up of suflicient tension on the expiring web to cause the new roll to gain its initial rotation and bring its gummed extremity into contact with the expiring web to adhere thereto, followed b the severance of the old web back of the pont of adhesion.

2. The method of making a flying paster of a fresh roll of web paper to the expiring web from a depleted roll being fed to press solely by the pull of the press itself, consisting of the use of a rotatable supporting a succes sion of rolls into Operating position, the ad-'` means for a plurality of rolls and means for rotating the same so as to bring a succession of rolls into Operating position, imposing a positive braking force upon the depleted roll, advancing the fresh roll into contact with the expi'ring web at a oint where such web has no suppleinentary acking, to cause the new roll togain its initial rotation and bring its gummed extremty into contact with the web to adhere thereto, and se`vering the old web back of the point of adhesion.

3. The method of making a' flying paster of a fresh roll'of web-paper to the expiring web from a depleted roll being fed to press solely by the pull of the press itself, comprising the use of a rotatable supporting means for a plurality of rolls and means for rotating the same so as to bring a succession of rolls into Operating position, the reduction of press-speed and regulation of webtension to a degree where, upon the advancement of a fresh rollinto contact with the expiring web 'at a point where such web has no supplementary hacking, such contact will impart' to the new roll an initial rotation,

bringing its gummed extremity into contact with the expiring web to adhere thereto, severing the old web back of the point of adhesion and 're-accelerating the ress.
