United States Patent 3,395,639 METHOD OF WEBBING A NEWSPAPER PRINTING PRESS George B. Swan, 505 Hicks St., Brooklyn, N.Y. 11201 Filed Nov. 16, 1966, Ser. No. 594,723 1 Claim. (Cl. 101-426) ABSTRACT OF THE DISCLOSURE A method of webbing a multipress unit newspaper printing press wherein each press unit is webbed while the printing press is idle and the printing plates are not on the type rollers.
The present invention relates to multipress unit newspaper printing presses, and more particularly to an improved manipulative method of arranging paper webs in the press units prior to putting such presses into operation.
Newspaper printing presses include a plurality of press units each of which prints on both sides of a paper web to provide up to sixteen pages of a newspaper, and a folder where the webs are collected to make up the newspaper. Each press unit generally comprises a roll for supplying a web of paper, first and second type rollers carrying printing plates, and first and second impression cylinders each co-operating with one of the type rollers to draw the web through the press unit and deliver it to the folder when the printing press is in operation. The press units are mechanically coupled to operate in synchronism and are each driven by a 40 HP. electric motor.
Heretofore, in the operation of such printing presses the paper webs were arranged in the press units in the manner about to be described. Each unit was webbed individually and in succession by manually withdrawing paper from the supply roll and inserting the leading portion of the web between the first type roller and impression cylinder. The printing press was operated to advance the leading edge portion for insertion between the second type roller and impression cylinder and to deliver the same to the folder. Each time another press unit was webbed in this manner the paper in the press units already webbed was further advanced whereby the paper delivered to the folder was wasted until all the press units were webbed and the printing press was in condition for productive operation. In an eight press unit tabloid newspaper printing press about 385 feet or 16.5 pounds of paper will be wasted by webbing the press in the foregoing manner.
Accordingly, an object of the present invention is to provide a method of webbing a multipress unit newspaper printing press for operation without wasting a large amount of paper.
A further object is to provide such a method which will effect a great saving in electric power by not starting and stopping the entire printing press each time a press unit is webbed.
Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claim, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
In the drawings:
FIG. I is a schematic view of a newspaper printing press illustrating a plurality of press units, a folder and the manner in which the press is webbed with paper.
FIG. II is an enlarged schematic view illustrating in 3,395,639 Patented Aug. 6, 1968 detail one of the press units shown in FIG. I and the manner in which it is webbed to the folder.
Referring now to FIG. I of the drawings in detail there is shown a newspaper printing press comprising eight press units A, B, C, D, E, F, G and H, by way of example, arranged in a row, and a folder 13 at the middle of the row of press units. The press units and the folder are on a floor 14 and paper supply rolls 1 are on a floor 15 beneath the floor 14.
As shown in FIG. II each press unit 12 has a roll 1 for supplying a web of paper 2, a first type roller 3 carrying printing plates, a first impression cylinder 16 co-operating with the type roller 3 to advance the web of paper while one side of the paper is being printed, a second type roller 6 carrying printing plates, at second impression cylinder 17 co-operating with the type roller 6 to advance the web of paper toward the folder 13 while the other side of the paper is being printed, and an idler roll 4 over which the paper web passes as it is advanced from the first set (3-16) of type roller and impression cylinder to the second set (617).
A number of rollers guide the paper web 2 as it is advanced towards the folder 13, and co-operating rollers 7 and 8 deliver the paper webs 2 of all the press units into the folder.
In accordance with the present invention, the printing press is put into productive operation by employing the method about to be described to web each press unit. While the printing press is idle and the printing plates are not on the type rolls a web of paper 2 is drawn from the supply roll by pressmen, the web is drawn upwardly and is passed between the type roller 3 and the impression cylinder 16 by pressmen, the web is passed over the roll 4, next the web is passed between the type roller 6 and the impression cylinder 17 and is conveyed to the folder 13 by pressmen, and finally the leading edge of the web is placed between the rollers 7 and 8 to hold the same in place and ready for delivery to the folder.
The press units shown in FIG. I are webbed in the order of D, C, B, A, E, F, G and H.
When the leading edges of all of the webs have been collected and are 'held in place between the rollers 7 and 8, the printing plates are mounted on the type rollers 3 and 6, and, when each press unit is in order, the power source of the printing press is started to put the same into productive operation.
It will be observed that during the webbing of the press units the power source of the printing press is not operated and that no paper is delivered to the folder 13. This means that no power is consumed and very little paper is wasted at the folder.
While the foregoing described method may be performed entirely manually by pressmen, the time required to webthe press units can be shortened byutilizing a mechanism for drawing and feeding the Web after it has been passed over the roll 4. Such a mechanism comprises a drive roller or trolley 5 co-operating with the roll 4 to advance the web, and a belt 9 driven by a pulley 10 on the drive shaft of a small motor 11 to effect rotation of the roller 5.
When this mechanism is utilized, the web 2 is drawn from the supply roll 1 and its leading edge is passed over the roll 4 as described before. The roller 5 is then placed into engagement with the web and the motor 11 is started. This causes the leading edge to be advanced to the type roller 6 and the impression cylinder 17 while more paper is drawn from the supply roll. The motor is operated until sufficient paper has been drawn from the supply roll to enable the leading edge of the web to be conveyed to the folder. The motor then is stopped and the roller 5 is moved out of engagement with the web.
It will be observed that this mechanism makes it much easier for the pressmen to handle the web than when all steps are performed manually.
From the foregoing description, it will be seen that the present invention provides a simple, practical and economical method of Webbing a multipress unit newspaper printing press.
As various changes may be made without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that the matter herein is to be interpreted as illustrative and not in any limiting sense.
1. The method of webbing a newspaper printing press solely in a press which includes a folder and a plurality of press units, each unit having a roll for supplying a Web of paper and each until having first and second printing couples, each of said couples having a cooperating plate cylinder and impression cylinder, and in the web path between each of said first and second printing couples there being located two peripherally cooperating drive rollers mounted for movement between an engaged and web-feeding position and a disengaged nonfeeding position, one of said cooperating rollers being driven by a [motor separate from the web-press drive and separate from the feed-roll drive of the other units, which method comprises performing the following steps in sequence for each press unit while all of the units of the printing press are idle and while all of the printing plates are off of the plate cylinders; drawing the web of paper from the supply roll; passing the withdrawn we'b between the first plate cylinder and its cooperating impression roll; passing the web between the nip of said feeding rollers while said feeding rollers are in said disengaged position; engaging and actuating the drive rollers to thus grip and feed the web; guiding the Web between the second plate cylinder and its cooperating impression cylinder and to the folder While propelling the web with said driven feed rollers; disengaging and deactuating the said drive rollers; collecting and holding the leading edges of all the webs at the folder; mounting the printing plates on the plate cylinder; and thereafter starting the printing press to put the same in productive operation.
