Description
Jan. 17', 1933. c. s. CARLSON ATTACHMENT FOR PRINTING PRESSES Filed Oct. 29. 1930 q INVENTOR 672 r /e5 C al'ison ATTORNEY Patented Jan. 17, 1933 PATENT OFFICE CHARLES S. OAIELLSON, F DUMONT, NEW JERSEY ATTACHMENT FOB PRINTING PRESSES Application filed Gotober 29, 1930. Serial No. 492,064.
This invention relates to an improved attachment for printing presses, an object of the invention being to provide an attachment which may be operatively connected to the printing press and function to insure a proper longitudinal feeding of the paper during the slicing operation and after said operation, so as to prevent any lateral movement of the cut sheets.
F or convenience in binding, it is necessary to cut or slice a wide sheet of paper as it is fed from the printing press, and with constructions heretofore known the two halves of the slit sheet have a tendency toward sidewise or lateral movement which precludes the possibility of perfect work.
It is the broad idea of my invention to provide a means which will cause the two halves or sections to run longitudinally after they are cut or sliced.
While my invention is particularly adapted for use in connection with what is known as an extension delivery fiat bed press, I do not wish to be limited to the use of the attachment in connection with any particu lar press as it is obvious that its utility is unlimited.
With these and other objects in view, the invention consists in certain novel features 30 of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims,
In the accompanying drawing- Figure 1 is a fragmentary view in side elevation, showing my improved attachment in operative position on a printing press;
Figure 2 is a view in transverse section on the line 22 of Figure 1; and 40 Figure 3 is a fragmentary plan view showing the presser rollers and their mounting.
Throughout the drawing the several fea-, tures of construction constituting my improved attachment are shaded, while the other features of construction illustrating a standard type of press are left unshaded.
The reference character A is employed to indicate a printing press, 1 a printing roll constituting part of the press, and 2-2 are arms constituting a part of the press or frame structure.
3 and 4- represent upper and lower endless tapes between which the paper sheet 5 is fed. The upper tapes 3 at their inner ends are mounted on a roller 6, and the lower tapes 4: are positively driven by a roller 7 which is in advance of the roller 6, as clearly indicated in Figure 1 of the drawing. 8 indicates more or less diagrammatically a slicer which slices the sheet 5 longitudinally as it is fed from the press to a position between the tapes 3 and 4.
My improved attachment includes a pair of brackets 9 which are secured by bolts 10 to the arms 2 of the printing press, and have laterally projecting lugs 12 thereon in which set-screws 13 are mounted and bear against the upper and lower faces of the arms 2 to permit a limited pivotal adjustment of the bracket-arms 9. These arms 9-extend upwardly and at their free ends support a rod 14 which may be secured therein in any desired manner.
On the rods 1% arms 15 are mounted anc carry at their free ends rollers 16 which bear upon the paper sheet 5 and press the same against a roll 17 located below the same and between the runs of the lower endless tape 4-. This roll 17 has trunnions 18 at its ends, which are mounted to turn in brackets 19. The brackets 19 are of somewhat angular form, pivotally supported between their ends and having fingers 20 thereon, with setscrews 21 in the fingers engaging the under faces of fixed portions of the printing press so as to permit of certain angular adjust ment of these brackets 19 to proper position the roll 17. The roll 17 is of the same diameter as the tape roll 7, and a sprocket chain 22 connects sprocket wheels 23 and 24 fixedly secured on the roll 17 and roll 7 respectively, so as to insure a positive driving movement of both rolls at the same speed.
It is desirable that there be an adjustment so asto give the proper tension or frictional engagement to the rollers 16 against the paper, and with this idea in view I have illustrated set-screws 25 fer securing the arms 15 on the rod 14 at any desired angle rela-- tit e to bracket arms 9, and as the latter is alsoiadjusted through the medium of its setscrews 13 the pressure may be regulated to exactly suit conditions. In any event it is necessary that the pressure be such as to hold the two sections of the slit sheet against the possibility of lateral movement, and hence it is preferable to have the rollers 16 relatively close to the slit portions of the sheet, as shown clearly in Figure 2.
When the printing press is equipped with In improved attachment the sheet can be slit longitudinally as it is fed from the press, and the sections thereof will be compelled to move in perfect alignment so as to prevent any possibility of lateral movement of the sections and consequent bad results in folding thereafter.
While I have illustrated what I believe to be the preferred embodiment of my invention, it is to be distinctly understood that various slight changes may be made with regard to the form and arrangement of parts without departing from my invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.
What I claim is:
1. An attachment for printing presses, including a slicer, a roll over which the sliced paper is fed, pressure rollers engaging the paper above the roll and rotatable thereby and located at opposite sides of the slice and compelling both sections to move longitudinally and preventing lateral movement thereof, endless tapes between which the paper is fed over the roll, the rolls supporting and imparting motion to the tapes, and a sprocket chain connecting the sprocket wheels on one of the tape rolls with the first mentioned roll.
2. The combination with a printing press having a slicer thereon, of an attachment for guiding and conveying sheets of paper from the press after the sheets have been sliced, said attachment including an endless-belt conveyor comprising rollers and endless tapes mounted on said rollers, an adjustable bracket, an additional roller carried by said bracket intermediate one pair of conveyor rollers and movable with said bracket for position ing said roller, means for rotating said rollers at the same speed, and pressure rollers located above said intermediate roller and adjustably spaced therefrom for receiving the sliced portions of paper therebet-ween, said pressure rollers being parallel with the slice and adjacent thereto for preventing lateral divergent movement of the sliced portions and for urging the same positively against said endless tapes and intermediate roller, said pressure rollers being rotatable with said intermediate roller for forwarding the separated portions of the paper.
A printing-press attachment for slicing unconnected individual pieces of sheet material, including a slicer, a roll over which the sliced pieces of material is fed, alined pressure rollers rotatable in parallel planes and engaging the sliced portions of the individual pieces of material above the roll and rotatable thereby, said pressure rollers being located at opposite sides of and adjacent the slice and compelling the sliced portions of the individual pieces to move longitudinally and preventing lateral movement thereof, and means for positively turning the roll at the speed of the moving material.
CHARLES S. CARLSON.
