Definitions

• the invention relates to a turning bar arrangement and method for deflecting a web according to the preamble of claim 1, 2, 10 or 11.
• material webs in particular paper webs
• the width of which is a multiple of the width of the finished printed product In order to produce the finished printed product from the printed web, it is necessary to cut this web into a plurality of partial webs, which are initially guided parallel to one another, but which have to be placed one above the other, in order to then produce the finished printed product, usually by folding lengthways and Cross direction and cross cutting to be processed.
• cross-cutting the superimposed material webs it is important that the printed pages on the individual material webs are exactly in phase with each other so that when cross-cutting all material webs are cut at a border between two sides.
• register rollers are used, the adjustability of which makes it possible to adjust the length of the path of a material web through the turning bar arrangement in such a way that pages which are to be processed for a signature come to lie exactly one above the other on the various webs.
• This turning bar arrangement comprises a first turning bar, which is displaceable transversely to a feed direction of the material web to be deflected, as well as two register rollers and one register roller.
• the register roller can be moved in a plane below the turning bar. If a large number of material webs are to be placed on top of one another, a stack of one above the other is used for this purpose Turning bar arrangements used. However, a small number of material webs to be placed one on top of the other is already sufficient for this stack to be man-high in the known turning bar arrangement, which considerably complicates their maintenance and the drawing in of the material webs when a job is changed.
• DE 38 16 900 A1 has disclosed a device for moving narrow paper webs in the form of partial paper webs.
• DE-AS 17 61 899 shows vertically offset turning bars.
• the US 37 34 487 A shows two triangularly arranged turning bars, of which a material web can be guided on a register roller.
• EP 07 84 590 B1 shows a turning device in which a guide roller and the turning bars have different diameters.
• the turning bars arranged at 90 ° to each other have the same diameter.
• the invention has for its object to provide a turning bar arrangement and method for deflecting a web.
• the advantages that can be achieved with the invention consist in particular in that the overall height of the turning bar arrangement can be kept small, so that the number of turning bar arrangements that can be mounted one above the other within a predetermined overall height is increased. In this way, the number of material webs that can be superimposed in a stack of turning bar arrangements can be increased without the stack having to have a height that is one Makes it difficult for the operator to reach individual turn bar arrangements of the stack in order to maintain them or to draw in a material web.
• a portion of the web extending between the first turner bar and the registration roller defines a first plane which is substantially horizontal in the conventional turner bar assemblies. Since the turning bar and the register roller, viewed from a direction perpendicular to this plane, do not overlap, they can be arranged to overlap, viewed from a direction parallel to the plane, so that the overall height can be reduced.
• a particularly effective use of the available construction volume results if the first turning bar and the register roller are arranged on the same side of this first level.
• the register roller has a larger diameter than the first deflecting rod, the material web which is guided around the deflecting rod and the register roller can be removed crossing the deflecting rod without additional deflecting elements being required for this.
• a second turning bar is required for a turning bar arrangement with an outlet direction parallel to the running-in direction of the web, and the material web can expediently be looped around the first turning bar, the register roller and the second turning bar.
• At least one of the two turning bars can be converted from an orientation parallel to the other turning bar into an orthogonal orientation, this allows the turning bar arrangement to be operated either with a parallel or with an anti-parallel inlet and outlet direction.
• a quick and exact change in the orientation of the reversible turning bar is achieved if the turning bar is rotatable about an axis that intersects the turning bar at a distance from one of its longitudinal ends, and a mark is attached to this longitudinal end that is in the parallel or orthogonal orientation with one of two complementary markings on a support of the turning bar can be made to coincide. It is therefore sufficient to check the congruence of the markings when moving the turning bar to be sure that the turning bar is set precisely at the angle.
• the exact setting of the turning bar is also simplified when the markings have a spatial shape and can be brought into positive engagement. With such a construction, the engagement of the markings already guarantees an exact alignment of the turning bar without the alignment having to be checked laboriously by an operator.

• the arrangement of the deflection roller arrangement 16 and the register roller 14 laterally offset beyond the side frames 01 and outside the range of movement of the turning bars 06, 07 along the guide profiles 02 enables the overall height of the turning bar arrangement to be kept low. Since the diameter of the register roller 14 is larger than that of the first turning bar 07, both can be arranged on the same side of the plane E, which contributes to a further reduction in the overall height.
