17 Claims. (Cl. 270-52) The present invention relates to printing presses, and more particularly to an angle bar arrangement for handling printed webs and for discharging them into a former folder or the like.

It is an object of the invention to provide an angle bar arran ement which is more flexible than the arrangements previously available, enabling web sections from a slit web to be received from the left-hand, middle and right-hand portions of the web for discharge in superimposed relation in any desired order and with the desired side of each web section facing upwardly. It is another and related object to provide an angle bar arrangement which enables webs to be received from presses located on opposite sides, either alternatively or simultaneously, for discharge in either of the two lateral directions and with the web sections from the opposite sides interleaved in any desired order for complete flexibility of page and color position.

It is a further object to provide an angle bar arrangement which is not only capable of receiving web sections from any position in a wide web, but in which the web-guiding rollers are substantially shorter than the web with consequent reduction in roller unbalance, whipping and inertia. It is a related object to provide an angle bar arrangement in which the web leads between points of support are substantially shorter than in more conventional arrangements. It is an object as a result of the foregoing to provide an angle bar arrangement in which web breakage is reduced to an absolute minimum under all conditions of operation, including rapid changes in speed.

It is still another object to provide an angle bar arrangement which is capable of handling a large number of web sections simultaneously but which nevertheless has improved accessibility, enabling the web sections to be threaded quickly and easily. It is a further and related object to provide an angle bar arrangement which not only permits easy threading but in which the necessary adjustments may be made quickly and with extreme accuracy to reduce the setup time and in which final adjustment of lateral register may be conveniently made with the press in operation.

It is still another object to provide an angle bar atrangement which not only provides accessibility, but which is extremely compact, enabling its use in press rooms having limited ceiling height.

It is another object of the invention to provide an angle bar arrangement which, possesses numerous operating advantages, but which at the same time may be easily and inexpensively constructed and which is inherently rigid and durable.

Other objects and advantages of the invention will 2,733,061 Patented Jan. 31, 1955 2 be apparent upon reference to the attached specification and drawings in which:

Figs. 12a-12h and 13a13h illustrate diagrammatically the discharge of web sections one and two pages in width. v

While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawings and have described in detail only the preferred embodiment. It is to be understood, however, that I do not thereby intend to limit the invention to the form disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

Turning now to the drawings, Figures 1 and 2 show an angle bar arrangement generally indicated at 20 being fed from opposite sides by printing presses 21-, 22, respectively. These printing presses may be of the conventional type employed for magazine color printing and each consists of a number of printing units. The web fed to the angle bar arrangement is slit by a slitting means 26, 27, the web being thereby divided into web sections having a desired width, being a maximum of two pages in the present embodiment. The angle bar arrangement discharges laterally into a folding, cutting and delivery mechanism 23 which in the present instance includes a former type of folder. The presses 21, 22 print one side of the respective webs. In order to demonstrate the flexibility of the present arrangement, it will be assumed that the remaining sides of the webs are printed on separate presses (not shown) capable of printing in one and two colors.

As shown in Figures 3 and 4, the angle bar arrangement 20 includes a frame having a pair of upright end members 24. and 25. Extending between the

end members

24 and 25 and supported thereby are a plurality of cross members 31-36. The cross members are" ar ranged in horizontally spaced pairs, as follows: 31, 32; 33, 34; and 35, 36.

In accordance with the present invention, the cross members each have way surfaces thereon which extend the full width of the web, with angle bar carriages bridgingly mounted on the way surfaces, each of the carriages having a width which is sufficient to accommodate any single web section, making it possible for a given carriage to be moved into a position of alinernent with any desired section of the web. In the illustrated embodiment it will be assumed that the incoming web indicated at from press 21 (Fig. 3) is five pages wide, and that it is slit into three web sections, two of the sections having a width of two pages and the remaining section having a width of one page. These web sections are designated 41, 42, 43, respectively. It will further be assumed that the incoming web from press 22 is slit in the same manner into

sections

51, 52, 53.

Further in accordance with the invention, two carriages are mounted for independent movement flatly one above the other on a single pair of transverse members. In the present embodiment a total of six angle bar carriages are employed, making it possible for the angle bar arrangement to handle all six of the web sections simultaneously. As shown in Fig. 4, these carriages are designated 61-66, the

carriages

61, 62 riding on the upper pair of cross members, the

carriages

63, 64 riding on the middle pair of cross members, and the

carriages

65, 66 riding on the lower pair of cross members. Each of the carriages may be easily adjusted into a position of alinernent with any desired web section. The manner in which each carriage is supported and clamped in its alined position will be made clear as the discussion proceeds. It will be seen that the arrangement of angle bar carriages enables the web sections to be led to any one of the carriages and to be discharged into the folder 23 in any desired order and with either side up for complete flexibility of color position.

Attention may next be given to the construction of the individual carriages as set forth in Figs. 5 and 6. Taking the carriage 61 by way of example, it will be seen that it includes a rectangular frame 70 in the general shape of a picture frame having web-receiving

sides

71, 72 and web discharge sides 73, 74, respectively. As shown in Fig. 5, the web section 41 enters at the side 71 and is discharged at the side 73. For turning the web at right angles an angle bar 75 is used which is detachably mounted across the diagonal of the frame 70. As shown in Fig. 5, the angle bar is mounted on

pads

81, 82, where it is pinned or otherwise fastened in place.

Pads

83, 84 are provided for mounting the angle bar 75 at right angles thereto for discharge in the opposite direction.

In order to guide the web section to the angle bar, receiving

rollers

85, 86 are employed. These rollers are mounted in

suitable bearings

87, 88, and are preferably of light construction fabricated of either steel or aluminum tubing. It will be noted that the

rollers

85, 86 are mounted outboard of the frame construction so as to engage the web section without obstruction. The

rollers

85, 86 are not employed simultaneously, the roller 85 being used when the web section is received from the left and the roller 86 being used when the web section is being received from the right.

As illustrated in the lower portion of Fig. 5 and as described above, turning the web at 90 is accompanied by a reversal" and the web is simply guided face down from the carriage by the discharge roller 92. For the purpose of guiding the web from the angle bar into the former folder and for again reversing the web so that it may be discharged face up rather than face down, as may be necessary,

discharge rollers

91, 92 are used. For face up discharge, the angle bar is mounted in its alternative position and the web is passed around the roller 91.

This latter condition is illustrated in the upper portion of Fig. 5 where like elements have been designated by like reference numerals with subscript a. A web section, for example 42, is received by the roller 85a, passed around the angle bar 752., and then around the roller 913. This re-establishes the face up condition and the web is discharged from the roller 92a.

The flexibility of the present arrangement, while apparent from Fig. 5, may be more clearly appreciated by reference to Fig. 3. Here the receiving rollers at the left-hand side of each of the carriages are designated 85, 85a, 85b, 85c, 85d and 850. Any one of the

Web sections

41, 42 or 43 may be led to any one of such receiving rollers, as indicated by the dotted lines in this view. Similarly, at the right-hand side of the carriages the rollers are indicated at 86, 86a, 86b, 86c, 86d and 86s, respectively. The web sections supplied from the righthand side and indicated at 51, 52 and 53 may in turn be fed to any of the receiving rollers, provided only that the particular carriage is not previously occupied by a web section being fed in from the other side. It will be appreciated that any web section thus received from either the right or left-hand side may in addition be discharged either face up or face down simply by passing the web section around the inactive discharge roller on the particular carriage. Still further contributing to the flexibility is the fact that all of the web sections may be discharged forwardly as viewed in Figs. 1-3 into the folder 23, as shown, or all may be discharged rearwardly into a folder 23:: (Fig. 2), or, if desired, a portion of the webs may be discharged forwardly and a portion rearwardly.

It will be apparent from the preceding discussion that the width of each of the carriages may be limited to correspond to the width of the widest web section which it is desired to accommodate. Where a former folder is used a web section two pages in width is the maximum which need be handled, the two pages being folded prior to cut-off. Since the width of the sections is only a fraction of the total width of the web and since the length of the rollers and angle bar may be correspondingly reduced when employing my invention, it will be apparent that the distance between the various rollers and between the rollers and the angle bar is reduced to an absolute minimum. It has been found that this reduction in spacing enables a greater degree of control, with less fluttering of the web and with less tendency for unbalanced forces to be set up in the web section which might result in a tear, particularly where an edge nick or other defect is present in the web.

A further advantage of the roller and angle bar arrangement described herein is that the rollers may all be reduced to a fraction of the length normally required. It will be apparent that the shorter length reduces the amount of inertia correspondingly, inertia being one of the factors tending to produce web breakage. In addition, the short length of the rollers enables a lighter construction to be used and reduces the degrees of unbalance of whip which tends to set up unbalanced transient forces in the web, resulting in breakage.

' In carrying out the invention, and as mentioned above, the angle bar carriages are mounted in closely spaced pairs. This mounting feature is particularly well brought out in Figs. 6 and 11 (which are opposing views based upon Fig. 5) where it will be noted that the

carriages

61, 62 are both supported from the same pair of

cross members

31, 32. In the preferred embodiment, the cross member 31 has an upper way surface 95 and a lower way surface 96, and the cross member 32 has an upper way surface 97 and a lower way surface 98. The carriage 61 is bridgingly supported on the upper way surfaces 95, 97, while the carriage 62 is suspended from the lower way surfaces 96, 98. The two carriages are spaced together rather closely, leaving only enough space '5 to provide clearance between them so that they can slide past one another.

In the preferred form of the invention illustrated in the drawings, the cross members 3136 are Z-shaped in cross section. The advantage of this will be seen in Fig. 6 where it will be noted that the frame of the carriage 61, together with a bolted-on bracket 10%), serves snugly to embrace the upper part of the Z, thereby pre venting play either vertically or in a sidewise direction. Along the opposite side of the carriage remote from the adjusting rod 102 is a similar bracket 1% which coperates with. the frame of the carriage to prevent play in a vertical direction. Sidewise clearance is provided, however, to prevent the carriage from binding on the ways. Thus, the spacing between the Ways Q5, 97 is non-critical, reducing the cost of machining and setup, sidewise clearance being provided at the side of the carriage is remote from the adjusting rod;

For the purpose of adjusting an individual carriage to a precise position of alinement, the present construction incorporates a novel coarse-fine adjustment feature. This feature is shown in Figs. and 11 in connection with the carriage 62. It will be understood that a similar construction is used for the remaining carriages, for example 61, the corresponding elements being designated without subscript. in practicing the invention, the adjusting rod 192 is arranged parallel to the transverse members and in sliding engagement with the carriage 62. This permits the carriage 62 to be manually moved to an approximate position of alinment. Means is provided for clamping the carriage 62 to the rod N2 in such position. in the present embodiment a simple bolt operrated clamp 933* is used.

For'the purpose of providing more accurate positioning of the carriage, means is provided for moving the rod bodily in an endwise direction. Thus the rod 1G2 is slidably mounted in bushings M4 (only one of which is shown) and is threadedly coupled at its end 105a to a rotatable adjusting shaft 195 For convenience the latter may be rotated by means of a hand wheel or the like (not shown) from a vertically extending shaft 167*. It will be apparent upon inspection of Fig. 10 that after the carriage 62 is clamped in its approximate position of alinement, rotation of the shaft 107a will cause the shaft 102a and hence the carriage to be movedforwardly or backwardly through a small range. if desired handwheels for the adjusting rods associated with each of the carriages may be conveniently arranged at the same operating position. This enables the angle bars to be adjusted to a fine degree by the pressman when the press is running, and the change brought about by the adjustment may be quickly noted.

The flexibility of the present angle bar arrangement may be more fully appreciated by observing the manner in which a web section only one page in width may be handled. Single-page web sections cannot, of course, be discharged centrally into the former folder, but must occupy either the right-hand position or the left-hand position. Where the single page Web section occurs at the middle of the web it is a simple matter using the present device to position the carriage along the ways to give either right or left-hand discharge.

it is one of the more detailed features of the present invention that such right or left-hand discharge may be accomplished even where the single page web section is along one edge of the web rather than centrally located. This is accomplished by providing an extension indicated at lit) in the elevational view, Fig. 4, and in the plan view, Fig. 8. he extension is sufficient to allow the carriage to be moved a distance equal to one page width beyond the edge of the web. In Fig. 8 the carriage 61 is illustrated in its extended position. An incoming web section 41 is turned by the angle bar 75 and is discharged in the right-hand position to the-former folder. It will be apparent that where left-hand discharge is required it is. suflieient to move the carriage 61 inwardly along the ways an. appropriate amount. While Fig. 4 shows an extension in one direction only, it will be apparent to one skilled in the art that the other end of the frame may be extended outwardly if desired to enable the carriages to be located in the opposite extreme position.

As an alternative to extending the side framing as described above to accommodate single-page web sections, a bent angle bar may be employed as disclosed in Fig. 9. Here it will be noted that the bent angle bar indicated at is provided with a two-point support in both directions, as indicated at 116, 117. Support at each of these points may be provided by bolts or the like so that the angle bar is maintained in its proper position in spite of the overhand. The same bent angle bar may be employed in an alternate position, as indicated at 1153. for receiving a web section from the opposite side and for discharging it into the left-hand position of the former folder. it will be understood that where face up delivery is required, it is suflicient to use the long angle bar and to pass the web around the idle discharge roller prior to discharging it. It will cause the web to be discharged at the same side of the folder. If desired the bent angle bar may be used in its position 115a, for face up discharge at the opposite side of the folder. In the latter case the carriage will have to be shifted a small amount to compensate for the thickness of the angle bar.

One of the features inherent in the present construction is that of accessibility. It will be appreciated that threading a web in a conventional angle bar arrangement is a. rather diflicult and time-consuming procedure. Because of the long web leads, normal access is obstructed. and in addition there is danger that the webs will be torn in the process of threading them. Iri the present arrangement, by way of contrast, long web leads are eliminated and the necessary angle bars and guiding rollers are all concentrated in a position of alinement with a given web section. Furthermore, the carriages are arranged in pairs mounted on a common set of cross members with just enough clearance for the adjacent carriages to be moved independently of one another. The separate pairs are, however, spaced apart a distance which is substantially greater than this, enabling the pressman to lean part way inside of the assembly while threading a web. In practice the spacing between the adjacent pairs of carriages may be on the order of two feet.

In spite of the extreme accessibility provided by the present construction, the overall height is substantially less than that required by conventional angle bar arrangements of the same capacity. Consequently, the present unit is ideally suited to press rooms where the ceiling height is limited. Further to facilitate accessibility, it will be noted that the open rectangular or picture frame construction of the individual carriages enables the pressman to reach completely through the carriage as may be required in threading.

To illustrate the versatility of the present angle bar arrangement, a number of possible leads are shown in Figs. l2zz-l2h and 1351-1311. Figs. l2a12a' show a web section two pages wide takenfrom the left-hand and central portions of the web and discharged either face up or face down. Figs. l2e-l2h show a web section only a single page in width being discharged either face up or face down and to either the right or left-hand side of the former folder. In connection with Figs. 12a and 1211, the bent angle bar 115 is employed, making it unnecessary to extend the angle bar framing and guideways laterally beyond the press in the forward dischar e direction. These guideways are, however, extended rearwardly as shown in Pig. 8, permitting a web run as shown in Fig. 13b and permitting a straight angle bar to be used for a single page web section for all conditions of discharge.

The figures show only one-quarter of the possible web leads for each of the carriages since Webs may be received fromthe right" as well as fromthe left and may be discharged rearwardly as well as forwardly. When receiv ing web sections from the right the web run will be a mirror image of that shown. For discharge to the rear the folder will of course be located in the opposite position as shown in dot-dash outline at 23a in Fig. 1.

It will further be appreciated that while a single carriage has been illustrated in these figures, the particular web section may be fed into any one of the carriages and consequently discharged in any position or order relative to the remaining web sections. The present angle bar arrangement is therefore suited to the most exacting ty e of color work and enables a maximum degree of flexibility, thereby reducing the amount of time which the pressman must spend in arranging the color plates and reducing setup time.

The angle bar arrangement in spite of its flexibility is simple and straightforward and inexpensive to construct and requires substantially no maintenance. Because of the unit construction of the carriages it will be apparent that the angle bar arrangement is applicable to a wide variety of sizes and types of printing presses, it being sufficient to shorten or extend the cross members to accommodate the device to various web widths.

While the terms discharge sides and discharge rollers have been used in the claims to emphasize the flexibility of the present arrangement, it will be understood that only one of such sides and the corresponding roller will normally be used for discharge, the remaining or idle roller being utilized for purposes of reversal to provide face-up discharge.

The term coplanar as used in the present claims shall be understood to describe a condition in which two webengaging elements are spaced from one another in substantially the same plane for passage of a web section from one to the other.
