'Ihis invention relates to the process of connecting a new roll of paper with an expiring roll which is being delivered to the press or other machine when lthe expirlng roll is running at high speed, that is for making a high speed paster be'- tween the new roll and the expiring roll, and is particularly directed to the preparation of the new roll to insure proper connection between the will of this new roll and the web of the expiring ro In making v'this high speed paster the press or other machine to 'which the paper is being delivered is run at high speed, and it is desirable to be able to change thedelivery of the paper from the expiring roll to the new" roll without malterially reducing the sped. In order to do this the new roll must Abe brought up to the desired speed, which is approximately the speed of the web being delivered, and the loose end of the web of the new roll must be lin sealed condition while it is being brought up to speed so it will bein proper condition to be connected with the web of the expiring roll. Furthermore, the leading edge of the web of the new roll must lift away clearly from the roll'when the'pasting contact is established. Adhesive mustv be used to connect the'webs of the two rolls together, and this adhesive must be applied to the leading edge of the new roll in such manner as to allow lateral clearvance for thev belts by means of which the roll is brought up to speed, this lateral clearance being desirable tol permit proper margining.

The present invention has as its object to secure this result. The invention has asa further object to provide means for reinforcing the' leading edge of the new roll that .is to be connected to the expiring roll so as to prevent a tear from developing due to the stress induced in lifting the leading edge away from the roll at the start of' the paster. The invention has as a. further object to provide means so that the operators can easily recognize and remove the copy of the paper con-l Fig. ji is a sectional view'taken on line I-l through the leading edge of the new roll and the reinforcing member thereof. Likenumerals refer to like parts throughout the several figures.

In making high speed pasters the rolls of paper 5 are mounted upon a roll support so that they may be successively brought into pasting position. Any suitable roll supporting device may be used and I have illustrated one form of this device, consisting of a reel having a shaft l which is lo rotated in any desired manner. This vshaft has arms 2 between which the rolls of paper are supported. A plurality of spaced belts 3 are in posi;- tion to contact with the periphery of the roll of lpaper while the paper is being delivered to the 1I press. When the roll from which the paper is fed is about exhausted, and which I have here designated the expiring roll, the roll supporting device is moved so as to move this expiring roll 4 out of contact with the belts. The web 5 of this go expiring roll passes over a pressure member 8 on its way to the press. The new roll of paper 1 is prepared for the high speed paster as follows:

The leading edge 8 of this roll is reinforced in some proper manner, and as herein shown it is g5 reinforced by the reinforcing strip 9 which is attached to this leading edge 8. This strip may be placed on either side of the leading edge 8, but I prefer to place it on the outside thereof, and the reinforcing strip 9 projects beyond the leading 30 edge 8. ,This reinforcing strip, as herein shown, has portions 9a which project beyond the leading edge. This reinforcing strip, in addition to being connected to the leading edge 8, is also connected to the periphery of the new 'roll 1 beyond the 35 leading edge, this connection being made by the portion 9a'. The reinforcing stripl is connected tc the leading edge and to the periphery of the roll in a suitable manner, preferably by adhesive, the adhesive being arranged so it will not be forced 40 out beyond the edges of the parts when the paster is being made. The reinforcing strip is weakened -between the parts by means of which it is connected to the leading edge 8 and to the periphery of the new roll. This weakening may be done by perforating the reinforcing strip. I may have one, two or more rows I8 of perforations, but one of these rows of perforations is preferably opposite the f extremity of the leading edge. Adhesive is placed on the outer face of the leading. edge as at Il. When the reinforcing strip is on. the outside of the leading edge, the adhesive may be placed on it, this adhesive extending only crosswise along a portion of the leading edge so as to le'avespaces I2 for the belts 8 by means 55 2 ananas the press and is printed thereon, the man at the folder can ascertain which paper has the pasted edge and can remove it if desired. These tabs may be colored so as to more easily attract at,- tention.

When the new roll is prepared for the high speed paster, as herein indicated, and the rollV fromwhich the paper is being delivered to thel press is about exhausted, the roll supporting device is moved so as to move the expiring `roll 4 away from the belts 3 and the new roll 'l into contact therewith. These belts are driven at proper speed and when the new roll is brought into contact therewith, the belts engage the new roll 'I at the points where there is no adhesive and rotate the new roll so as to bring it up to the desired speed. When the new roll has attainedthe desired speed, the rollsupporting device ismovedl further so as to press the new roll against the web 5 of the expiring roll at the point where said web passes around the presure device 6. This causes the adhesive on the leading edge 8 of the new roll to be pressed against the web 5 of the expiring roll with suilicient pressure to cause it to adhere thereto. This leading edge of the new roll then adheres to the web of the expiring roll, and with a shearing and lifting action breaks the reinforcing strip at the weakened portions thereof so that the web of `the new roll passes along with the web of theexpiring roll and is delivered to the press or other machine in connection with which the device is used. The delivery of the paperis then changed from the expiring roll to the new roll. 'Ihere is considerable stress on the leadingvedge of the new roll when the paster is to beffmade, and the reinforcing strip `prevents lthe stress from tearing the leading edge of vthe new roll.

In the applying of the adhesive to the reinforcing strip and leading edge, it'should be applied carefully and preferably in a thin coat and in such position thereon that it will not be forced beyond the leading edge or reinforcing strip so as'to come into contact with any parts of the press. The indicating tabs Il and l5 indicate to the party at the folder where the paster is made and this paper can be removed.

It will be seen that by means of this process the high speed paster can be easily, quickly and y eectively made at any desired speed without any interference, and that 'the new roll may be connected to the web of: the expiring roll in a completely eifective and satisictory manner, and the reinforcing strip, in addition to reinforcing this leading edge, acts to releasably connect the leading edge with the periphery of. the new roll. VIt will be noted that the leading edge of the new roll is releasably connected with the periphery of the roll beyond this leading edge. scribed the process in the claims with the steps in a certain order, but it is of course evident that the steps may be taken in' different order from that set forth in the Iclaim:

' beyond the leading edge, and a series of perforations extending through the reinforcing member substantially parallel with. the straight leading edge of said web and inA proximity thereto, whereby the' reinforcing member performs two func- I have det'ions, one to reinforce the leading `edge of the web and the other to attach it to th'e periphery of the roll.

y 2. A roll of paper arranged for making Ihigh speed pasters comprising a web having a substantially straightl leading edge near the middle of the roll and extending along the greater portion of the length of the froll, a separate reinforcingv member attached to said leading edge of said web, means for connecting said reinforcing member with the convolution at the surface of the roll which underlies the last convolution of the roll, said members being provided with perforations adjacent the edge of the last convolution on the roll and between such edge and the portion of the underlying convolution to which the reinforcing member is attached.

3. .A roll of paper arranged for making high speed pasters comprising a web having a substantially straight leading'edge near the middle of the roll and extending along the greater por'- tion of the length of the roll, 'a separate reinforcing member attached to said leading edge of the web and extending therealong, and a weakened connecting means forming a part of the reinforcing means for connecting said reinforcing member with the convolutiomat the surface of
