FORM 2 THE PATENT ACT 1970 (39 of 1970) & The Patents Rules, 2003 COMPLETE SPECIFICATION (See Section 10, and rule 13) 1. TITLE OF INVENTION SUPERSTRUCTURE FOR A FOLDING EQUIPMENT OF A WEB OFFSET PRINTING MACHINE 2. APPLICANT(S) a) Name b) Nationality c) Address MAN ROLAND DRUCKMASCHINEN AG GERMAN Company MUEHLHEIMER STRASSE 341, 63 075 OFFENBACH GERMANY 3. PREAMBLE TO THE DESCRIPTION The following specification particularly describes the invention and the manner in which it is to be performed : - The invention relates to a superstructure for a folding equipment of a web offset printing machine according to the main term of the claim 1. From the DE 38 11 909 C2 a superstructure for a folding equipment of a web offset printing machine is known, wherein the superstructure covers several driven rollers. The driven rollers are also known as draw rollers. From the DE 38 11 909 C2 it is already known, to provide bearing for driven rollers on one side at a wall of a stand or frame of the superstructure, wherein such a one sided bearing of rollers is also known as suspended bearing. From the DE 38 11 909 C2 no reference can be taken, as to how the rollers with single sided or suspended bearing are driven. For superstructures for folding equipment, which have driven rollers with single sided or suspended bearing, drive trains for driving of rollers are arranged on the side opposite to the side of the wall, at which the roller has one sided bearing. According to this the driven roller and the drive train for the same are positioned at different or opposite sides of the wall of the superstructure, so that the drive train can drive-in only with coupling elements duly connected in series in a roller to be driven. Hereby a complex design effort for the superstructure is caused. Based on the above the problem forming the basis for the present invention is to create a new kind of superstructure for a folding equipment of a web offset printing machine. This problem is resolved through a superstructure for a folding equipment according to claim 1. According to the invention the driven roller is suspended as rotatable on a carrying axle, which has a rigid connection at one end with the wall, wherein a drive train for the roller is arranged on the same side of the wall like the carrying axle and the roller engaging the wall, and wherein the drive train directly drives-in in the roller. In the sense of the present invention, the drive able roller and the drive train for driving the same are arranged on the same side of the wall of the superstructure. 2 Hereby the drive train can drive-in directly without further coupling elements in the roller. Hereby a relatively easily designed and thus cost effective architecture of a superstructure can be implemented for a folding equipment of a web offset printing machine. The drive able roller is suspended as rotatable on a carrying axle, which is rigidly connected at one end with the wall. Since the drive train drives-in in the roller and not in the carrying axle for the roller, at the carrying axle other modules of the superstructure can engage, so e.g. end plates for press rollers or press rolls or draw rolls, which roll on the drive able roller. Thus fixing and suspension of press roller or press rolls or draw rolls with minimum space requirement and lower cost is possible. Preferred further developments of the invention emerge from the sub-claims and following description. Execution examples of the invention, without being restricted to this, are explained in detail on the basis of the drawing. It shows: Fig. 1: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a first execution example of the invention; Fig. 2: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a second execution example of the invention; Fig. 3: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a third execution example of the invention;. Fig. 4: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine 3 according to a fourth execution example of the invention; Fig. 5: a side view of the superstructure of Fig. 4; Fig. 6: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a fifth execution example of the invention; Fig. 7: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a sixth execution example of the invention; Fig. 8: a side view of the superstructure of Fig. 7; and Fig. 9: a schematic, partial cross section through an invention based superstructure of a folding equipment of a web offset printing machine according to a seventh execution example of the invention. Fig. 1 shows a cutout from an invention based superstructure for a folding equipment of a web offset printing machine in the area of a driven roller 10, wherein the roller 10 is suspended as rotatable on a carrying axle 11 above bearing 12, and wherein the carrying axle 11 is rigidly connected at one end with a wall 13 of a stand or frame of the superstructure. A drive train 14, which serves the drive of a driven roller 10, is arranged here on the same side of the wall 13, like the carrying axle 11 and the roller 10, so that the drive train 14 can drive-in directly or without any means and coupling elements in the roller 10. The drive train 14 in the execution example of Fig. 1 is formed by a driven gear 17 suspended on a drive shaft 15 of a drive 16, a drive-in gear 18 allocated to the roller 10 and a drive belt 19, wherein in the execution example of Fig. 1 drive-in gear 18 allocated to the roller 10 is integral part of the driven roller 10. 4 A second execution example of an invention based superstructure for a folding equipment of a web offset printing machine is shown in Fig. 2, wherein for the execution example of Fig. 2 for avoiding unnecessary repetitions for identical modules, same reference numbers are used. The execution example of Fig. 2 distinguishes itself from the execution example of Fig. 1 in the fact that in the execution example of Fig. 2 the drive-in gear 18 allocated to the roller 10 is developed as separate module, which is connected distortion-free with the roller 10. Regarding all other details one can refer to the execution example of Fig, 1 for executions. Fig. 3 shows a cutout from another invention based superstructure for a folding equipment of a web offset printing machine in the area of a driven roller 10, which is suspended as rotatable on a carrying axle 11 above bearing 12. The carrying axle 11 is in turn rigidly suspended at one end at a wall 13 of a stand or frame of the superstructure, wherein a drive 16 for the roller 10 is integrated in the same. In the execution example of Fig. 3 the drive train according to it is formed exclusively by drive 16. One can do away with a driven gear, drive-in gear and a drive belt in the execution example of Fig. 3. Fig. 4 shows a cutout from another invention based superstructure for a folding equipment of a web offset printing machine in the field of a driven roller 10, wherein the driven roller 10 of Fig. 4 is executed in conformity with the execution example of Fig. 2. In the execution example of Fig. 4 a press roller 20 is allocated to the driven roller 10, which rolls on the driven roller 10 and it is driven through friction by the roller 10. The press roller 20 is suspended as rotatable through bearing 21 at a spindle 22, wherein end plates 23 for suspension of spindle 22 and thereby of press roller 20 engage at the carrying axle 11 of the driven roller 10. In the execution example of Fig. 4, according to it, the carrying axle rigidly connected at one end with the wall 13 of the stand or frame of the superstructure assumes namely the function of bearing the 5 press roller 20 besides the function for bearing the driven roller 10. Fig. 5 shows a side view of the superstructure of Fig. 4, wherein in Fig. 5 however two driven rollers 10 with respective press rollers 20 have been represented, and wherein both the rollers 10 are driven from a common drive 16 via the drive belt 19. Through adjusting cylinders 24, which are advantageously executed as pneumatic cylinders, the press roller 20 can be disengaged from the driven roller 10 or can be engaged with the same. In Fig. 5 the drive 16 has relative to the upper roller pair a different relative position than with respect to the lower roller pair, whereby different conditions for changing the drive belt 19 emerge. In case of upper roller pair 10, 20 for changing the drive belt 19 the dismantling of the end plate 23 is essential, whereas in case of lower roller pair 10, 20 the drive belt can be replaced even without dismantling the end plate. Fig. 6 shows a another execution form of an invention based superstructure of a folding equipment, wherein the execution example of Fig. 6 differs from the execution example of Fig. 4 in the fact that on the driven roller 10 not one press roller covering the entire axial width rolls, but several press rolls 25 distanced from each other roll rather along the axial direction. The press rolls 25 are in turn driven through friction by the roller 10 and are suspended as rotatable on a spindle 22, wherein the end plates 23 for bearing the spindle 22 and thus for bearing of press rolls 25 in conformity with the execution example of Fig. 4 in turn engage at the carrying axle 11 of the roller 10. Also the execution example of Fig. 7 shows a cutout from an invention based superstructure for a folding equipment of a web offset printing machine in the area of a driven roller 10 developed analogically to Fig. 2. Regarding details for the roller 10 one can refer to the above executions. In the execution example of Fig, 7 on the driven rollers 10 two press rolls 26 and one 6 cutting roll 27 roll. The press rolls 26 and the cutting roll 27 are suspended at a spindle 28 as swivel able, wherein engages the spindle 28 with one end firmly at the wall 13 of the stand or frame of the superstructure. The press rolls 26 and the cutting rolls 27 can be individually disengaged via one each of swivel mechanism 29 from the roller 10 or these can be engaged with the rollers. Each of the swivel mechanisms 29 covers a spring element 30 and a pneumatic connection 31, wherein the compressed air fed via the pneumatic connections 31 engages the press roll 26 or the cutting roll 27 against the spring force of the spring element 30 at the driven roller 10. On interrupting the compressed air feed, depending on the spring force of the spring elements 30 the press roll 26 or the cutting roll 27 is disengaged from the roller 10. As one can see from Fig. 7, in the driven roller 10 a slot 32 has been provided, which functions in tandem with cutting knife allocated to one of the cutting rolls 27 to separate a news print roll during transport along the roller 10. A further execution example of an invention based superstructure of a folding equipment of a web offset printing machine is shown by Fig. 9, wherein also in the execution example of the Fig. 9 the driven roller 10 is executed analogically with the execution example of Fig. 2, because of which for avoiding unnecessary repetitions for identical modules same reference numbers are used. In the execution example of Fig. 9, on the driven roller 10 roll driven draw rolls 33, wherein the draw rolls 33 likewise the driven roller 10 are driven from the drive train 14. For this purpose, the drive belt 19 of the drive train 14 is engaged not only with the drive-in gear 18 of the driven roller 10, but rather continues with a drive-in gear 34, which is suspended on a spindle 35, wherein the spindle 35 transfers the drive energy provided by the drive 16 on to the draw rolls 33. End plates 23 for the spindle 35 in turn engage at the carrying axle 11 of the roller 10. Similarly, thought of by the inventor, though not represented in Figure 9, is an adjustable engaging fixture of draw rolls 33 at the roller 10, for example for designing variable pressing 7 pressures via torque converter bearings. It is common to all execution examples that a one sided or flying suspended driven roller 10 of a superstructure of a folding equipment of a web offset printing machine and a drive train 14 are arranged for driving the roller 10 on the same side of a wall 13 of a stand or frame of the superstructure. The driven roller 10 is suspended on a carrying axle 11 which is rigidly coupled with the wall 13 of the stand or frame of the superstructure. The drive train 14 can drive-in directly in a drive-in gear 18 allocated to the driven roller 10. This is done in the shown execution examples via a drive belt 19, which is preferably executed as toothed belt. In contrast to this, this can also be done via enmeshing gears. At this point it may be expressly pointed out that the invention based superstructure of the folding equipment can be deployed also at other location in the printing machine, e. g. in the printing unit or between printing units as transport equipment. 8 10 Roller 11 Carrying axle 12 Bearing 13 Wall 14 Drive train 15 Drive shaft 16 Drive 17 Driven gear 18 Drive-in gear 19 Drive belt 20 Press roller 21 Bearing 22 Spindle 23 End plate 24 Adjusting cylinder 25 Press roll 26 Press roll 27 Cutting roll 28 Spindle 29 Swivel mechanism 30 Spring element 31 Pneumatic connection 32 Slot 33 Draw rolls 34 Drive-in gear 35 Spindle 9 CLAIM: 1.
