Definitions
- This invention relates generally to presses and particularly to a retaining device for the turning or reversing bars of the transverse arms in a rotary press.
- Reversing bars are employed in rotary printing presses for the purpose of reversing the direction of the printed sheets, webs of paper, or other materials through an angle of 90. These bars are commonly mounted at an angle of 45 with respect to the direction of travel of the sheets.
- these reversing bars are secured by a retaining unit at both ends of the transverse arm.
- the bars For the purpose of turning the sheets to the opposite side, the bars must first be unscrewed, and after being displaced through an angle of 90, they must be bolted down again.
- structure above the folding apparatus is required, which in turn necessitates considerable space and represents an appreciable cost.
- the changeover of the transverse bar when altering the direction of travel of the strip is time consuming and complicated. This also applies to the introduction of sheets when the press is being initially set up for production.
- reversing bars are operatively secured to a transverse arm at only one end, so that once the retaining parts are loosened, the bars are capable of being reset through an angle 90.
- a retaining unit is disposed about the transverse arm and is capable of being shifted axially therealong.
- the retaining units each include a plate with a cross-slot which is mounted at an angle of 45 with respect to the transverse arm.
- the reversing bar is interlocked with the retaining unit by means of a setscrew which is provided at the center of the cross-slot.
- the retaining unit need not be completely loosened. All that is necessary is to loosen the setscrew, whereupon the reversing bar may be veered through an angle of 90 about the setscrew.
- the reversing bar is then secured in the new position, in the other arms of the cross-slot by means of the same setscrew.
- the arrangement of each of the plates with a cross-slot above and below the transverse arm for the accommodation of the turning bars prevents collisions between the several reversing bars and also prevents the collision of the strips between the bars.
- FIG. I is a plan view of a series of retaining units and reversing bars in a press illustrating features of the invention.
- FIG. 2 is an end view of the apparatus of FIG. 1.
- FIG. 3 is a plan view of an enlarged scale of the retaining unit and reversing bar.
- FIG. 4 is an elevation view of the retaining unit of FIG. 3.
- FIG. 5 is a cross-sectional view taken along FIG. 4, and
- FIG. 6 is a schematic paper strip movement diagram for two series of reversing bars.
- a paper web 3 is passed between a pair oflateral supports I and 2. As shown in FIG. 1, web 3 may be cut as at 4 into eight individual strips 5.
- a reversing bar 6 is provided for each individual strip 5. Each reversing bar 6 is mounted at an angle of 45 to the web 3 and the individual strips 5 and serve to turn the strips 5 through an angle of with respect to the direction of travel.
- the individual strips 5 which are thus arrayed one above the other are then fed into a folding apparatus over guide rollers (not shown).
- the Position of the reversing bars designated by the solid lines in F G. 1 four strips run to the left and four strips run to the right.
- the reversing bars which are positioned to the right must be shifted into the position indicated at 6' by the broken lines. Any other positions of the reversing bars may be required, say three strips to the left and four strips to the right, with the web being subdivided into seven individual strips. In this operation one of the reversing bars is standing idle. In the example shown in FIG. 1, the length of each reversing bar 6 is so devised that in lieu of eight such bars, resort may also be had to four strips turned to a double width in lieu of the eight strips.
- a retaining unit 7 is provided for each reversing bar 6, and is displaceably secured on a transverse arm or on a crosspiece 8. Each unit 7 is secured against rotation by means of a wedge 17 (FIGS. 2 and 5) which runs through the crosspiece 8. Above and below the crosspiece 8 each of the retaining units 7 is provided with a plate 16 (FIG. 5) in which a cross-slot 21 is formed. The arms of slot 21 are disposed at an angle of approximately 45 to the crosspiece 8. Fitted into the said slot is a wedge 20 ofa receiving unit 18 (FIG. 4) which is secured by screws 19 to the end of each reversing bar 6.
- a setscrew 9 which passes through the receiving unit 18 near the end of the reversing bar.
- the bar may be readily pivoted about setscrew 9 through an angle of 90 as illustrated by the broken line in FIG. 3.
- the reversing bars 6 are each individually laterally displaceable to the direction of travel of the web 3 as may be required when resetting the format from, say, six to five strips. This is accomplished with the aid of the shafts 10 which are mutually coupled with the aid of spur gears II, 12 (FIG. 2) and driven jointly via the bevel gear pair 13. Where it is necessary to displace a given reversing bar 6, the respective coupling I4 is joined and the adjusting sleeve 15 (FIG. I) rotates along with the shaft 10 and displaces the desired retaining unit 7 along with its associated reversing bar 6.
- the number of shafts 10 is determined by the number of reversing bars which are to be displaced in this manner.
- FIG. 6 shows schematically a lateral view of the reversing bar design in the case in which presses respectively feeding a web 3 from the right and left are provided on both sides of the folding apparatus. The web is cut into individual strips between the blades 22 and the blade rollers 23.
- a rotary press having a transverse arm and a reversing bar, means for adjustably securing said reversing bar to said transverse bar, comprising;
- a plate slidably disposed about said transverse arm having a cross-slot formed therein oriented at an angle of approximately 45 with respect to said transverse arm, screw means passing through one end of said reversing arm and received at substantially the center of said cross-slot for releasably locking said reversing bar in first and second positions with respect to said transverse arm, said second position being displaced through an angle of approximately 90 with respect to said first position.
