Description

[Brief explanation of the drawing]

An example of a preferred embodiment of the invention is shown in the drawings, in which FIG. FIG. FIG. 2 is a sectional exploded view of a part of the mechanism for controlling the pivoting movement of the suction device of the paper transfer cylinder depicted in FIG. 1; FIG. 3 schematically shows a side elevation of the strip printing cylinder taken in the direction of arrow A in FIG. It shows the location. Figure 4 shows
2 is a schematic cross-sectional view of the side elevation of the paper transfer cylinder taken along line B-B in FIG. 1, illustrating the position of the suction device on the paper transfer cylinder in lithographic duplex printing for the shortest paper length; FIG. It is something that FIG. 5 is a schematic side elevation view of the strip transport cylinder taken in the direction of arrow A in FIG. 1, illustrating the adjustment of the suction device in lithographic duplex printing for maximum strip length. FIG. 6 is a partial cross-sectional view of the paper transfer cylinder taken along the line BB in FIG. It is a depiction of FIG. 1 is a schematic side elevational view of the strip transport cylinder taken in the direction of arrow A in FIG. 7, illustrating the adjustment of the suction device in multicolor printing for minimum strip lengths. FIG. 8 is a partial cross-sectional view of the strip transfer cylinder taken along the line B--B in FIG. 1, illustrating the position of the suction device in multicolor printing for minimum strip length. Figures 9 and 10 are views similar to Figures 7 and 8, respectively, depicting the adjustment and position of the suction head in multicolor printing at maximum strip length. FIG. 11 is a schematic diagram, partially in section, of the arrangement for transporting paper strips between two printing presses. In the figure, 10 is a paper transfer cylinder, 11 is a paper support disk, 12 is an elongated hollow shaft, 16 is a suction section, 18 is a suction head, 27 is a handle, 32 is a control shaft, 33 is a latch, and 34 is a peripheral slot. , 51 is an external gear, and 69 is a control lever arm.

Claims (1)

[Claims for Utility Model Registration] 1. A cylinder for transporting elongated pieces of paper for a rotary printing press, comprising an elongated hollow shaft; comprising a plurality of gripping devices for gripping leading ends of the pieces of paper to be transported, and these grips an apparatus disposed circumferentially spaced on said hollow shaft for rotation therewith and carried by said hollow shaft; and comprising a plurality of suction heads for supporting trailing edges of sheets of paper to be transported. , each suction head being circumferentially adjacent to and circumferentially spaced from said one handle device; comprising an elongated control shaft, said control shaft being disposed inside said hollow shaft; are arranged with their longitudinal axes parallel to each other, and the control shaft is rotatably mounted so as to be able to change its rotational angular position relative to the hollow shaft; a latch pivotally mounted on a shaft; a circumferentially extending peripheral slot formed in the hollow shaft; a latch extending radially from the control shaft and connected to the suction head through the peripheral slot; a coupling device for pivoting the suction head relative to the hollow shaft in response to rotation of the control shaft relative to the hollow shaft; an external gear fixed to an axial end of the hollow shaft; The adjusting device includes a control lever arm fixed to the shaft end of the control shaft, and a fixing member that adjusts and fixes the external gear and the control lever arm by adjusting their relative rotational angular positions. An elongated sheet transport cylinder for a rotary printing press, characterized in that the sheet transport cylinder is accessible from the outside. 2. The elongated paper strip transport cylinder for a rotary printing press as claimed in claim 1, wherein the longitudinal axis of the control shaft coincides with the longitudinal axis of the hollow shaft. 3. The rotary printing device according to claim 1, which includes a plurality of handle units, and wherein the suction heads operatively associated with these handle units are connected to each other so as to be jointly pivotable. A long thin paper transfer cylinder for machines. 4. The utility model according to claim 3, which includes a plurality of handles and suction head units, and the suction heads of each suction head unit are firmly connected to each other and can be rotated jointly. Long paper strip transfer cylinder for rotary printing presses. 5. A device for causing the suction head to make an angular reciprocating motion, the angular reciprocating device being provided between the external gear and the fixed member, and a ram that is eccentrically supported by the external gear; a cam roller carried by the ram; an intermediate ram connecting the ram to the control ram arm; a spring biasing one of the rams so that the cam roller is in an actuated position; and a stationary spring acting on the cam roller. 5.
