MEANS FOR IQAKING HIGH SPEED FASTER-S Filed March 11, 1925 Patented Dec. 3, 1929 UNITED STATES PATENT OFFICE EDWIN W. HAMMER, EAST ORANGE, NEW JERSEY, ASSIGNOR 'IO CLINE ELECTRIC MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS MEANS FOR MAKING HIGH-SPEED IPASTEBS Application filed March 11, 1925. Serial No. 14,637..

In the printin of newspapers there are certain factors which are unique in that the printingoi a newspaper edition is postponed to the very last practicable moment, in order ill to include the latest news, but when the printtil ing ot the edition begins, the aim is to complete the running 0d of the edition as soon as possible in order that the papers may be distributed or sold without delay. In consequence oil this demand, there has been developed apparatus which is in daily use in many newspaper printing plants whereby a plurality oit rolls of paper are made immediately available at the press so that as one roll of paper becomes depleated, a fresh roll may be e uickly brought into position to take its place.

his is eected through the use of a magaaine reel or roll stand having a rotatable memher with entending arms adapted to carry a plurality of rolls. The common form of this apparatus includes a press-driven traveling belt arrangement so placed as to maintain the surtace of the traveling belt in contact wit-h the active roll of paper. Such belt may be arranged to drive the roll or retard it if desired, and is of assistance in effecting what is fill till

lanown as a flying paster.

lhe flying paster is another out-growth of the demand for time-saving in the newspaper lant and is the joining of the web from a i'resh roll to the expiring web of a depleted roll without actually stopping the press. Betore the flying pastor was evolved it was necessary to stop the press each time a new roll was to be introduced and this involved a delay of several minutes. As the usual roll expires in about twenty minutes run, this means a replacing of each roll three times an hour with a loss of nine minutes per hour for each roll running to press. In a press using four rolls it will be seen that more than fifty percent ot the time was taken up in changing rolls, because it ractica-lly never happens that two rolls can e changed at precisely the same time. The flying paster cut down the time out melting the change very materially, because the combination of magazine roll and press slowing (instead of press stoppage) has cut down the usual time of making a change to a minute and a half, or a little less. It is thus seen that a press capable of turning out thirty thousand copies per hour it run contmuously never turns out thirty-thousand an hour because so much time is talren up in slowing the press. making the tlying paster and ire-accelerating the press once more. In order to make the flying paster it is usual to cut the press speed down to onequarter or less its tull speed rate. lit is thus evident that although the flying paster was a distinct help, it is a flying paster only in name as there has never been in practical operation a newspaper press in which a fresh roll can be attached to an expiring web at high speed.

it s the object of the present invention to provlde an apparatus with which a paster may be made at high speed. The preferred form of apparatus embodying this invention 1s shown in the accompanying drawing in which a magazine roll stand is illustrated. embodying pedestals 1 adapted to'support a shaft 2 upon which are mounted spiders with arms 3 adapted to carry rolls of web paper 4, 5 and 6. On the roll stand is an electric motor 7 for adjusting the spiders so as toplace the active roll of paper in proper pos t on and to bring a fresh roll into proper position to resume the supplying of webpaper to the press. The motor 7 drives the large gear wheel 7 secured to the spiders, through proper gearing. Another electric motor 8 is utilized to shift the rolls of paper laterally so as to adjust the margin.

Pressing against the active roll 4 is a travelmg belt 9 moving in the same direction as the web 4 going to press, such traveling belt 9 being carried by two pulleys 13 and 14 mounted upon a frame 12 pivoted at its upper end to a press-driven shaft supported in hangers 11. This is the conventional apparatus used for many years. To this apparatus I have added a second belt 15 running over pulleys 18 and 19 supported in a frame 17 pivoted at its upper end upon a shaft 16 held in hangers 22. The shaft 16 is also press-driven and may have an independent connection to the press drive or it may be driven from the shaft 10 by a sprocket chain 20 or may receive its driving force in any other convenient manner, provided dill Till

the result is a driving of the shaft 16 at such a rate as to give a speed to the belt 15 equal to that of the web 4 goin to press from the active roll 4 over the rol er 21. The frame 17 is preferably arranged at its up r end so as to rmit its being moved laterally al'ong the sha 16 which is provided with a continuous feather or key to rmit such movement while maintaining riving connection with the pulley 18. This ad ustabIe feature permits the belt 15 to rest at any convenient point upon the roll 5 which at times is of ful length or of fractional length, depending upon the number of pages in the edition being printed. A chain or cord 17 is preferably emplo ed to hold the frame 17 away from the ro except when it is desired toliltglize the belt 15 for the rotation of the ro It will be understood that in the operation of this apparatus the end of the new web on roll 5 is trimmed and has applied thereto a suitable adhesive, the flap of the web bein held down against the surface of the roll 5 b the igh speed pasteris to be made, at a time when the roll 4 is nearly exhausted, the belt 15 is brought into contact with the roll 5 at a convenient point, where adhesive has not been applied, and the roll 5 is thereu on caused to rotate and come up to the sEee of the belt 15, which is the speed of t e 4'. When this condition has been reached, the reel is rotated by the motor 7 and the roll 5 brought into contact with the web 4. If the movement of the reel is carried forward sufliciently,-the pressure of the roll 5 will forcethe web 4 into contact with the belt 9 and this may assist in effecting adhesion of the gummed portion of the web on roll 5 to the outgoing and nearly expired web 4. Adhesion 1s readil and safely made because the new web and 't e old web are both traveling at the same speed. When adhesion has taken place the old web is broken back of the oint and the reel is turned still further to bring the new roll into the most favorable ition for supplying its web to the press. h e arm B'carrymg the old roll 4 has by this action been swung around to the left of the pedestal 1, where it may be readily removed and a fresh roll substituted for it to prepare for a later use.
