Definitions
- the invention relates to a printing unit cylinder, suitable for high, flexographic, low and web offset printing presses, which has a roller, a tensioning element with a narrowed tensioning channel and a rubber covering, the top layer of which is worn away so far at the channel ends that the remaining ends can be inserted into the tensioning element so that no channel opening is visible on the rubber surface when tensioned.
- the rubber coverings should withstand the pressure, contain reinforcements with sufficient adhesion to the rubber layer, be easily replaceable and have a long service life, as well as have sufficient dimensional accuracy and uniform thickness.
- Adhesive layers can be used to attach the rubber coverings to the cylinders, but this leads to unsatisfactory results.
- An improved, but not yet optimal solution for rubber fixation is to set up mechanical holding systems, which are located in the so-called clamping channel of the cylinder.
- Measures must be taken to reduce or suppress the bending vibrations of the pressure cylinders at the channel inlet and outlet areas. Because the contact pressure between the cylinders increases the radius in the radial direction, starting from the reversible relaxation of the rubber blanket. As a result of the brief change in the pressing force between the cylinders, the channel impact or engaging shock then occurs when the counter-rubber blanket or printing cylinder comes back on, which leads to vibrations in the printing system. In this case, with a stretched rubber blanket, a gap remains open between the rubber blanket sections lying against the cylinder pit edges. Due to the above processes, the pressure process negatively affected.
- European patent application 0 194 618, application number 86103093.3, filing date March 7, 1986, describes this behavior of the bending dynamics of two printing unit cylinders when the tensioning channels overflow, especially in web offset printing presses.
- These edge increases on the clamping channel are achieved by tangential profile rails.
- DE-OS 34 37 309.8 attempts to solve the problem of the impact joint or channel run through a special design and configuration of the stiffening strips on the front and rear edge of the rubber blanket on a rubber blanket cylinder.
- the ground connection is therefore based on the task of changing the construction field of the tensioning channel in the use form, ie with the rubber covering applied, so that the total radius, taking into account the thickness of the rubber covering, is not increased and in this way there is no longer any interference or channel impact.
- the tensioning system must be designed in such a way that the mechanical stability of the cylinder is reduced as little as possible, twisting of screws is not possible, and the surface of the rubber covering is evenly tensioned.
- the object is achieved in that the upper layer of the rubber covering of a printing unit cylinder is removed so far at the ends and the remaining lower covering layer is then introduced into the tensioning system in such a way that no stretching channel opening is visible on the rubber surface, taking into account the expansion. I.e. the cylinders do not lose the rubber contact when the tensioning channel is rolled over its circumferential angular range, so that vibrations no longer occur if the cylinders meet one another after rolling over the channel or the insertion slot.
- the correction of the rubber covering ends together with the tensioning element according to the invention allows the tensioning channel to be changed so far that a twist-free tensioning system is created with which mechanically stable printing unit cylinders can be produced.
- Printing unit cylinder for high, flexo, gravure and web offset printing
- the claimed printing unit cylinder essentially consists of a roller, a tubular tensioning channel and a tubular tensioning element, each with insertion slots and a flat fabric which, after shortening at the channel ends in the tensioned state, completely covers the roller body.
- the entire backing layer rubber composition which is usually used as a pressure coating, is not in the tensioning device fixed, but the main strength member.
- the mechanical stress in the tensioning channel region, in particular on the rubber-rubber joint, is then largely absorbed by the strength between the carrier layer and the rubber layer.
- such a rubber covering is preferably chosen which has a high strength between the carrier layer and the rubber layer and has good dimensional stability, so that the printing properties of the printing unit cylinder claimed are further improved.
- composite films consist of a carrier layer, preferably a polyester film, such as Polyethylene terephthalate, which is crosslinked on one or both sides using known adhesion promoters, at least with a layer of NBR or other elastomers.
- a carrier layer preferably a polyester film, such as Polyethylene terephthalate, which is crosslinked on one or both sides using known adhesion promoters, at least with a layer of NBR or other elastomers.
- FIGS. 1-4 show four embodiments of such composite films which can be used as flat structures in the printing unit cylinder claimed.
- (2) is the adhesive layer.
- the carrier layer (1) preferably polyethylene terephthalate
- the carrier layer (1) can be crosslinked on one side with an elastomer layer (3) (Fig. 1), on one or both sides with one or two elastomer layer (s) (3 + 4) of different Shore A hardness ( Fig.2).
- the fabric can also consist of a carrier Layer (1), two elastomer layers (3 + 4) and an interposed driven layer (5) exist (Fig. 3), or also have an elastomer layer (4) with incorporated raster (Fig. 4).
- a rubber covering according to FIG. 1 is selected as a flat structure for the construction of the printing unit cylinder claimed.
- the arrangement shown in FIG. 5 results between the roller body and the flat structure.
- the upper layer in the example the elastomer layer (3)
- the elastomer layer (3) is now at the clamping edges of the rubber covering, e.g. by planing, milling or grinding to such an extent that the part still occupied corresponds exactly to the circumference of the cylinder and the planed, milled or ground ends are of equal length.
- the elastomer layer (3) is shortened again on one or both sides to the extent that the stretching under the tensioning force.
- the situation shown in FIG. 6 results for the flat structure.
- the elastomer mass (3) located above the base point B determines the extent of the increase in the total radius, i.e. the elevation depends on the angle ⁇ . If the angle ⁇ is 90 ° or more, there is no exaggeration, the purpose according to the invention is not achieved in the latter case.
- the rubber covering is tensioned, its curved surface above the clamping channel is increased to the total radius by means of a radial planer, radial milling cutter, radial scraper or radial grinding device, adjusted to the same or below it, and, as far as necessary, the tangential run-out taken into account in the total radius. In this way, it is possible to prevent the interference shock or channel blow.
- the minimum channel width required to clamp the ends of the rubber covering remaining after abrasion of the layer (3) depends on the total thickness of the covering.
- the minimum channel width is calculated as follows: generally 2 x base layer thickness 2 x 250 ⁇ m 500 ⁇ m minimum channel width.
- the minimum channel width is calculated generally 2 x covering thickness minus 2x abrasion thickness 2x1.95 mm - 2x0.85 mm 2.2 mm minimum channel width
- Printing unit cylinders for web offset printing (blanket cylinders), for high and flexographic printing (printing form and impression cylinders) and also for indirect gravure printing (blanket cylinders) can be equipped with the rubber covering which has been corrected and subsequently fixed in accordance with the invention in the manner described.
- the printing unit cylinder according to the invention consisting of a roller, a tensioning element with a narrowed tensioning channel and a flat structure laid out in the manner described, is also suitable for functioning as a flexographic printing roller.
- the type of the new pressure element allows the elastomer covering to be replaced in the shortest possible time. It is even conceivable to do without changing the printing roller. This is possible if the subject is laser-engraved separately and the elastomer printing form component is placed and clamped on the printing roller or core installed in the machine. A prerequisite for such a mode of operation is the dimensional identity and the same mechanical behavior of the cylinder in the laser engraving unit and that in the printing press.
- the surface of the rubber covering can also be designed in a known manner in relief, as is done in so-called cliché machines by pressing and vulcanizing.
- the printing unit cylinder described is a printing form cylinder.
- the elastomer plate joint can be closed with adhesives or a suitable adhesive.
- the correction of the rubber covering ends according to the invention can be carried out in a simple manner (planing, milling, grinding) and in the laid-on state. Due to the narrowing of the clamping channel, torsion-free clamping elements can be used and thus mechanically stable printing unit cylinders are created.
- the printing unit cylinder can be used in web offset printing (blanket cylinder) in indirect gravure printing (rubber cylinder), in high and flexographic printing (impression cylinder) or also in flexographic printing (printing form cylinder, flexographic printing roller).
