SUMMARY OF THE INVENTION The invention relates in general to printing machines and, in particular, to a new and useful attachment for a printing machine which includes an adjustably positionable guide rod for guiding printing paper webs issuing from the printing machine.

In present day folding arrangements for printing machines, the printed paperwebs are usually guided by a superstructure or by diagonal air rods which are built into a very cumbersome, expensive and relatively inaccessible superstructure system. When the direction of movement or position of the paper webs is changed, complicated rearrangement of the machine has to be effected and because of the inaccessibility of its upper structure, such rearrangement is difficult to carry out and is very time-consuming. In addition, it is extremely difficult to arrange for all of the different desired paths of ejection of the paper work in one superstructure.

In accordance with the present invention, an arrangement is provided for guiding printed paper webs from a printing machine which eliminates the disadvantages of the known fixed superstructures. The inventive device includes a number of slide assemblies which are movable transversely in grooves formed in one side of the printing machine and each slide assembly supports a guide rod extending obliquely outwardly from the one side of the printing machine. Advantageously, theslide assemblies are above the passages for the paper webs through the sides of the printing machine.

Accordingly, it is an object of the invention to provide an improved device for facilitating the guidance of paper webs away from a printing machine. In one embodiment, the device includes one or more slide assemblies mounted for movement in grooves along one side of the machine at locations over passages for the paper webs, each slide assembly including a guide rod over which the paper webs can be guided along a new path of travel.

A further object of the invention is to provide a guidance system for changing the direction of passage of the sheets of material, such as printed webs, which is simple in design, rugged in structure, and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter'in which there are illustrated and described preferred embodiments of the invention.

DETAILED DESCRIPTION OF THE INVENTION In the drawings, and in particular in FIG. 1, a portion of a machine frame 50 is shown, such as is used in a printing operation, and it includes a vertical wall 3 having vertically spaced longitudinally horizontally extending guide grooves 4 for slide assemblies 2. The slide assemblies 2 are each movable through one of the grooves in the longitudinal direction of the groove. The vertical wall 3 extends between

side walls

52, 54 of the machine frame, see FIG. 2.

In accordance with the invention, each slide assembly 2 includes a plate member 2D positioned against the face of the wall 3. A socket portion 2a is attached to one of the

ends

2A,2B of the plate member 2D and a guide rod 1 is held in the socket portion. In the arrangement shown in FIG. 1, the

opposite ends

2A, 2B, of the plate member of the slide assembly are formed at an oblique angle to the face of the wall 3 and the socket portions 2a are secured to the ends 2A so that they extend obliquely-from the wall in the rightward direction at an angle of about 45. As mentioned above, the socket portions 2a can also be secured to the ends 28 so that they extend at about 45 in the opposite direction, that is in the leftward direction as viewed in FIG. 1.

The wall 3 of the machine frame 50 is provided with a number of vertically spaced horizontally extending passages 5 for printed paper webs 7 which run from a printing machine, not shown, and are directed over the guide rods 1 for changing the direction of travel of the paper webs into new paper web feeding paths 7'. The passages 5 alternate and extend in parallel relationship with the guide grooves 4 across the width of the wall 3.

As shown in FIGS. IA and 18, each groove 4 has a T-shaped configuration with the head portion 4a of its T-shape spaced inwardly from the face of the wall 3 and the shank portion 4b extending to the face of the wall. Each slide assembly consists of the plate member 2D positioned against the face of the wall 3 and a T- shaped member 2E which seats within the corresponding T-shaped groove 4 so that it can be moved longitudinally through the groove and protected against displacement due to its T-shaped configuration. Extending through the plate member 2D to the T-shaped member is a threaded bolt 2C for securing the two parts together and for securing the slide assembly in position within the groove.

In the plate member 2D an elongated slot 2] is provided extending in the direction of the grooves 4 in the wall 3. Within the slot 2.] an angular member 2I-I is positioned and a bolt 2F connects the angular member to the T-shaped member 2E. By tightening the bolt 2F, the angular member 2H can be secured tightly to the wall 3. For coarse adjustment of one of the slide asemblies, both of the

bolts

2C and 2F are loosened and the slide assembly is movedmanually throughthe groove into the desired position. By tightening the bolt 2F the angular member 2I-I is secured to the wall and by tightening the bolt 2C the slide assembly is held tightly in position in the groove 4.

To afford fine adjustment of the slide assembly, a setting screw 6 is secured at one end in an abutment 2K rigidly secured to and projecting outwardly from the plate member 2D and at its other end the screw passes in threaded engagement through another abutment 21 secured to the angular member 2H. Note the arrangement of the setting screw 6 and the

abutments

2K and 21 in FIG. 1. An adjusting knob 6a is provided on the end of the setting screw 6 adjacent the abutment 2K.

When coarse adjustment of the slide assembly has been achieved, the angular member 2H is held tightly against the wall 3 by the bolt 2F. For effecting a fine adjustment, the bolt 2C is loosened slightly so that the plate member 2D can be displaced longitudinally along the face of the wall 3. While the plate member 2D can be displaced, the angular member 2H is held tightly against the wall 3. By rotating the setting screw in the appropriate direction, the plate member 2D can be moved relative to the angular member 2H and a fine adjustment obtained. When the plate member 2D to which the guide rod 1 is attached is located exactly, the bolt 2C is again tightened, the slide assembly is tightly secured to the wall, and the fine adjustment is completed.

If desired, instead of the manually operated setting screw 6, a motor-driven remotely controlled adjusting means can be provided as shown in FIG. 6. In FIG. 6, parts similar to those shown in FIG. I bear the same reference numerals. A slide assembly 2 is shown mounted in a guide groove 4 on one side of a vertical wall 3 of a machine frame 50. On the slide assembly 2 a coarse adjustment device 70 is provided for moving the slide assembly 2 and its associated guide rod 1 into the approximate final position. Once the coarse adjustment has been achieved, the guide rods can be finely adjusted by means of a motor 72 driven by a remote control from a control station, not shown. A worm gear 74 is secured to the motor aNd in turn drives a worm gear spindle 76. The end of the worm gear spindle 76 is threaded into an abutment 78 mounted onthe slide assembly 2. With the body of the slide assembly se cured to the wall 3, by operating the motor 72, the plate member 2D to which the guide rod is attached can be finely adjusted to bring it into the final position. Accordingly, even while the device is operating, it is possible to remotely operate the motor and move the guide rod slight distances to correct the misalignment which might develop.

On the opposite side of the wall 3 from the slide assembly 2 is a paper web guide roll 80 mounted at its opposite ends in bearing blocks 82.

The printed paper webs are moved from the printing machine over the guide roll 80 and through the frame 50 by a drawing and cutting

roller system

56, 56, see FIG. 2, and the direction of travel of each web is turned or changed as the web passes over one of the guide rods 1 during its movement along its path of travel. The position of each of the guide rods 1 is adjusted or set in dependence on the desired path of movement or ejection of the paper web. When the arrangement is provided with remotely'controlled setting-means for the slide assembly 2, then the guide rods can be moved individually during operation so that the paper webs can be directed or aligned exactly one above the other. Depending upon the position of the guide rod, the paper web, which is guided over this rod, can be supplied to a folding mechanism with the printed side pointing in the desired direction.

If necessary, the paper web 7 can be deflected by means of additional rollers 8 as indicated in FIGS. 2 and 3. The additional rollers 8 extend perpendicularly to the wall 3 and are mounted on the same side as the guide rods. In this manner, the paper web can be guided to the inlet side of the folding mechanism over a path which has been preselected in advance. The paper webs which change direction in passing over the guide rods are supplied to the folding inlet in a single registered arrangement. Due to the single registration provided, the paths of the paper webs are arranged so that the printed sides are superimposedin a covering manner. I

In the illustrations provided by FIGS. 2 to 5, addi tional schematic arrangements are indicated, each including four separate guide rods 1. Depending upon the position of these guide rods 1, the change in direction of the individual webs which, in this instance, is for separate webs 7, is made in such a manner that the colored sides, regardless of whether they are on the inside or' outside originally, are properly inserted into the folding mechanism.

With the inventive device, all possible variations can be realized by simply changing the positions of the guide rods. Within the scope of the invention as described above, other embodiments of the invention are possible. For example, though not shown, the slide assemblies can be provided with a rocking device to which the guide rods are secured. By means of the rocking device the guide rods can be moved into the desired angular position relative to the wall.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
