The principal object of the invention is to provide means for securing together the pages of a printed product, like a newspaper, sufficiently to hold them together while being read but not so securely that they may not be separated easily, and to provide means for perforating the sheets and at the same time forcing paste into and through the perforations for uniting the sheets.
Other objects and advantages of the invention will appear hereinafter,
. Reference is, to be had to the accompanying drawing, in which Fig. 1 is a diagrammatic View of a folding mechanism with a preferred form of this invention applied thereto;

Newspapers have been made in the past with the sheets or sections pasted together in such a manner that if it was desired to separate them it would practically necessitate tearing at least one sheet. These pasting devices are found to be inadequate for high speed presses and that practice has been discontinued very largely. With the introduction of the so-called tabloid newspaper having small pages, a large number of pages is necessary. This product is difficult to handle in the form of a newspaper on account of the slipping of the sheets of the loosely made up product,
This invention is provided especially for tabloid newspapers, although it is capable of use elsewhere, so as to permit the attachment of the sheets together in a way that will hold them for ordinary purposes but not absolutely prevent their being separated without tearing. For these purposes a couple is placed between the former and the transverse folding mechanism. This couple, of course, consists of two cylinders and one of them carries, longitudinally in line along its surface, a plurality of pasting means for perforating or fracturing the paper and introducing an adhesive at the fractured point. In the preferred form, these needles enter recesses in the other cylinder of the said couple and are so positioned that they will perforate the paper along the fold line of the product.
The invention is shown as applied to a folder for a printing machine which is shown diagrammatically in Fig. 1 as provided with the usual former I which delivers a longitudinally folded web over form rolls 2 through nipping rolls 3 and 4 to a couple 5 and 6 which contains the new feature of this invention. From this couple the web passes through the usual folding and cutting couple 1 and 8 to folding rolls 9 and delivery mechanism 10.
The pasting cylinder 5 cooperates with the backing cylinder 6 and they are both supported by frames II and I2. The pasting cylinder 5 is provided with a needle pipe 13 having secured to it a plurality of pasting needles M. This pipe 13 also has mounted on each end a roller l5 and I6 respectively. These rollers cooperate with stationary cams IT and I3 respectively carried on the two frames H and I2. A connecting pipe I9 is secured to the needle pipe and it telescopes into a pipe 20 fixed in the pasting cylinder 5.
The rotation of the pasting cylinder causes the pasting needles [4 to emerge from the surface of the cylinder 5 as they approach the backing cylinder 6 and project into recesses 29. They withdraw after passing the position shown in Fig. 3. This is accomplished by the operation of the rollers 15 and [6 by their respective cams.
A paste pipe 2| is shown as connected from a paste supply, not shown, preferably through a stuffing box, and is brought to the center of the pasting cylinder 5 at one end. Here the pipe 2! communicates with the pipe 20. A ball check valve 22 in the pipe 29 is pressed by a spring 23 intoclosed position. The right hand end of the spring 23, as shown in Fig. 3, bears against a spider-like section 24 which is fixedly mounted in the cylinder. A similar check valve 25 is carried in the pipe l9.
Figs. 4, 5 and 6 show the pasting pin M, which has been mentioned. This is threaded so that it may be inserted in the pasting pipe l3 and in 0 fact several of these pins are inserted in that pipe along one side of it. In each pasting needle is provided a central hole 26 communicating with the interior of the pipe l3 and employed to conduct paste from the pipe [3 into the needle I4. 45 This hole 26 terminates in three openings Zl, one in each of the three or more concaved sides. of the point of the needle. Preferably these needles are made triangular in shape with their three sides hollow ground. The holes punched thereby have three lobes which will open as the needles enter and tend to close as the needles are withdrawn. Paste is forced from these needles through the openings 21 which emerge, just short 55 of the point of the needle, from each of the three sides. It is not essential that this particular number of sides be employed but is is convenient for the purpose intended.
By a study of the check valves in pipes l9 and 20, it will be seen that, as the needle pipe [3 is moved outwardly, the check valve 25 will close and paste will be drawn into the telescoping part of the pipes l9 and 20 through the opening normally closed by the check valve in the pipe 20. This occurs at the time when the needles M are pushed outwardly by the cams and pierce the associated webs. As the cylinder continues to rotate, the needles begin to withdraw and the check valve and the pipe 20 remain closed while the check valve 25 opens. This forces the paste into the pipe 14 and out through the needles I4. Therefore, it is evident that holes may be punched in associated webs by a fan-1ike needle and that the paste in this needle may be used for applying paste to the several edges of the perforations in the several sheets while these edges are naturally tending to close up.
In this way a newspaper, particularly a tabloid, can be made without material additional expense so that when received by the reader the sheets are all pasted together at the several perforations that have been made along the fold line. It can be read by a single party without danger of the sheets slipping out or becoming displaced. At the same time, any section of it can be taken out so that two or three readers can read the same paper at the same time. The invention can be applied to ordinary newspapers and to other publications.
Having described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
1. In a newspaper folder, the combination of means for folding the newspapers, a needle for perforating the sheets of the newspapers, located in a position to perforate them at the fold line, and means for extruding an adhesive through said needle in the perforations.
2. A newspaper printing press comprising means for securing the pages of a newspaper together along its fold line, which consists of a series of perforating needles coincident with said fold line, the needles being adapted to extrude paste when passing into or out of the perforations made by them in the product.
3. A device for securing the pages of a newspaper together comprising needles adapted to perforate the newspaper along the fold line, and
means for extruding paste through the needles in a position to stick to the edges of the perforations in all the sheet of the newspaper.
4. A device for securing the pages of a newspaper together comprising needles adapted to perforate the newspaper, and means for extruding paste through the needles at the edges of the perforations in all the sheets of the newspaper.
5. A device for securing the pages of a newspaper together comprising a line of multi-sided needles, means for moving the needles to perforate all the sheets of the newspaper at the fold line, each needle having a longitudinal passage extending nearly to the point of the needle and emerging in openings in the several sides thereof.
