Definitions
- Clamping device for clamping a flexible covering of a cylinder
- the invention relates to a clamping device of a printing press cylinder, which serves to clamp a flexible covering of the cylinder to the cylinder.
- the invention can be used in particular in offset printing, preferably in web printing.
- a clamping device as the invention relates, is required in particular for blanket cylinders and forme cylinders of rotary printing presses in order to fasten a blanket or a flexible printing form, which is stretched onto a lateral surface of the cylinder 5, to the cylinder while maintaining the tension.
- the cylinders have one or usually several axial channels on their lateral surface, in or in which a clamping device is formed.
- a clamping device is known from USP 5,010,818, which has several cylindrical
- Clamping gap can optionally be formed with one or the other of the counter surfaces.
- the spiral springs are supported radially inwards on bearing bodies in the channel
- '5 are arranged. They are guided in the radial direction over part of their axial lengths.
- the clamping bodies have holes on their rear sides, into which the coil springs protrude.
- the inhibiting device requires several different, relatively movable components that must be arranged in the channel. When clamping a covering, the spiral springs are not only subjected to pressure, but also to bending
- a clamping device is formed by two clamping jaws, which enclose the clamping channel between them.
- One of the jaws is firmly connected to the cylinder.
- the other clamping jaw can be moved in the circumferential direction of the cylinder, so that the channel width measured in the circumferential direction can be changed.
- the two clamping jaws form two channel walls, to which the ends of a covering are placed.
- a hollow cylindrical spring element or a spiral spring is arranged lying in the channel.
- the movable clamping jaw takes up a position in which the channel opening is widest for pulling in the covering.
- One end of the covering is hooked into the channel so that it lies against one of the channel walls.
- the other end of the covering is then hooked in so that it lies against the other of the channel walls.
- the movable clamping jaw is adjusted to the other clamping jaw, on the one hand to clamp the covering on the cylinder and on the other hand to press the two ends of the covering against each other in the region of the channel opening and thereby clamp the covering.
- the spring element is compressed elastically so that after the clamping jaws have moved together, it presses against the ends of the covering projecting into the channel and prevents the covering ends from bulging outwards at the clamping point, ie in the region of the channel opening.
- the clamping device is complex.
- the clamping device comprises a spring bar pivotably mounted in a tensioning channel and a material-elastic clamping body against which the spring bar is pivoted to clamp two clothing ends.
- the female connector is attached to a -0 bearing body, which is circular cylindrical over part of its circumference.
- the channel is correspondingly shaped as a circular cylinder and forms a bearing shell for the bearing body.
- On the front of the bearing body is flattened.
- the elastic clamping body rests on the flat.
- the female connector is swiveled towards one of the two boundary edges of the channel by rotating the bearing body.
- the clamping body is arranged between the female connector and the relevant boundary edge.
- a clamping device for clamping a flexible covering of a cylinder of a printing press which has at least one axial channel on a lateral surface, comprises a clamping body which is arranged in the channel and with a first counter surface of the
- Channel forms a clamping gap for at least one end of the covering projecting through an opening of the channel.
- the two ends can be the leading and trailing ends of a single covering, preferably a rubber blanket or a printing form, or the ends of two coverings, each of which stretches only over part of the cylinder beginning.
- the first counter surface faces two channel walls, one of which forms a second counter surface and the other a third counter surface, on which the sealing body is supported by contacting the second and third counter surfaces.
- the clamping device further comprises a spring.
- this spring forms either the clamping body or at least one of the counter surfaces or both
- the clamping body and the first counter surface are preferably already pressed against one another by the elastic force when the covering is not drawn in, in this case the spring is thus preloaded.
- the elastic force of the spring ie the spring stiffness and possibly a prestressing force, is selected such that the at least one covering end or the two covering ends can or can be introduced into the clamping gap against the elasticity force, preferably manually.
- the first counter surface and the clamping body advantageously form a funnel which opens towards the opening of the channel and which narrows towards the clamping gap.
- the clamping body is shaped in such a way that the stringing end or stringing ends cannot become jammed when it is inserted into the clamping gap. Tensioning of the clamping device is not necessary, since the clamping device tensions itself by inserting the covering end or the covering ends into the clamping gap, or preferably tensions more in addition to a pre-existing tension. If the clamping device is not already pre-tensioned as preferred, the channel and the clamping body are shaped in a tight fit, so that the clamping force required for clamping the at least one clothing end has built up by itself at the latest when the at least one clothing end is in or through the Clamping gap protrudes.
- the clamping body forms the spring. It is material-elastic in a first variant and elastic in a second variant. It can also be combination of material and shape elastic.
- the material-elastic variant can be formed as a whole from an elastic material, for example an elastomer or rubber, or preferably as a composite body.
- an elastic material for example an elastomer or rubber
- it has an elastic material at least on a surface area forming the clamping gap.
- a composite body it preferably has a jacket made of an elastic material all around.
- the composite body has the advantage that another material that has a greater specific weight than the elastic material can be used for the formation of the Klenmic body in addition to the elastic material.
- a particularly preferred composite body forming the insulating body therefore has a core made of a material with an advantageously large specific weight, for example steel, and all around a jacket made of an elastic material.
- the core and the jacket are preferably integrally connected to one another; a frictional and / or positive connection alone or in combination with a material connection is also conceivable.
- the hardness of the elastic material should be at least 60 Shore, but on the other hand should not exceed 80 Shore.
- the sealing body In the variant in which the sealing body is form-elastic, it forms a resilient arch which is open on a side facing away from the first counter surface. By inserting the covering end or the covering ends into the clamping gap, the arch is elastically deformed and then clamps the covering with its restoring elastic force.
- the arch preferably stretches up to at least the second counter surface.
- the second counter surface is shaped and oriented such that it can form a second clamping gap with the insulating body, so that the covering end or the covering ends depending on the direction of rotation of the Cylinder between the clamping body and either the first counter surface or the second counter surface can or can be clamped.
- the form-elastic clamping body preferably ends at the two ends of the resilient arch in support feet which bear against the third counter surface, preferably such that they can slide off the third counter surface when the arch is deflected.
- the support feet further ensure that the arc maintains its angle of rotation position in the channel and is always opposite its surface convexly curved to the first counter surface and preferably also to the second counter surface of the counter surface in question.
- the spring forms one of the counter surfaces.
- the spring can, for example, be a covering made of an elastic material and fastened to the relevant duct wall, for example an elastomer covering or a rubber covering.
- an insert forms the spring, which is inserted into the channel wall in question in a depression specially formed for the insert.
- the insert preferably consists of an elastic material, for example an elastomer or rubber.
- the material-elastic counter surface it is also conceivable to design the material-elastic counter surface as a spiral spring with one clamped end and one free end or two clamped ends.
- the insert advantageously forms a flat surface with the duct wall in which it is inserted.
- a material-elastic covering or preferably insert should have a hardness of at least 60 Shore; on the other hand, the hardness should not exceed 80 Shore.
- the covering or insert can be provided with an abrasion-resistant surface.
- a thin but stiff metal plate can be attached to the surface of the covering or insert facing the channel, so that the covering or insert deflects evenly over its entire surface.
- Such a coating should also be flush with the surrounding duct wall. If the covering or insert does not have a solid surface, it can be advantageous if it falls slightly on the surface facing the channel in the channel, ie it is convex towards the covering end, in order to facilitate the insertion of the covering end touching it.
- both the clamping body and at least one of the counter surfaces each form a spring and the several springs formed in this way only compress together by the thickness of the at least one covering end, it corresponds to preferred embodiments if either only the small body or only at least one of the counter surfaces form the spring. If the clamping body is the spring, the counter surfaces are preferably not resilient, but hard. Conversely, if at least one of the counter surfaces forms the spring, the sealing body is advantageously hard.
- the clamping device advantageously allows the clamping of the at least one covering end optionally on both sides of the channel, so that it is invariant in the direction of rotation.
- the channel and the clamping device formed with it are preferably symmetrical with respect to a radial which points through the opening of the channel to the axis of rotation of the cylinder.
- the second counter surface points radially inwards from the channel opening in order to create a second clamping gap for the optional clamping of the covering in combination with the embossing body.
- the third counter surface faces both the first and the second counter surface, it would be sufficient if the third counter surface is elastic.
- the two counter surfaces optionally forming the clamping gap i. H. the first counter surface and the second counter surface are each formed by a spring as described above.
- clamping bodies of the type described can be arranged axially next to one another in the channel.
- Several of the clamping bodies can also be connected to one another on a shaft or axis. It also corresponds to preferred embodiments if only a single clamping body is arranged in the channel. If several clamping channels are formed in the cylinder, what has been said above regarding one of the channels applies equally to the other channels.

- FIG. 7 shows a clamping body in a clamping channel of a cylinder.
- FIG. 1 shows a part of a printing cylinder 1 near the surface of a web-fed rotary printing press for the offset printing of large newspaper runs.
- the cylindrical surface of the printing cylinder is covered with a flexible covering.
- the flexible covering is a rubber blanket 2, which is vulcanized or glued to a flexible plate 3.
- the drain cylinder is accordingly a blanket cylinder.
- the two free ends of the flexible plate 3 are inserted into a tensioning channel 6 and fastened in the channel 6 by means of a clamping device.
- the clamping device is formed with channel walls of the channel 6. The two clamped ends do not have to be the ends of the same plate and, in many applications, are not.
- the channel 6 extends axially, i. H. parallel to an axis of rotation Dz of the cylinder 1, in a region of the cylinder near the surface and forms a narrow channel opening 7 directly on the surface.
- the channel opening 7 is delimited by two boundary edges, namely by a boundary edge lv leading in the direction of rotation D of the cylinder 1 and by one trailing boundary edge 8n.
- the boundary edges lv and 8n are axially parallel in the circumferential direction.
- the channel 6 widens in cross section from the boundary edges lv and 8n on both sides of a radial R, which extends through the opening 7 onto the axis of rotation Dz of the cylinder 1.
- the opening 7 and the adjoining channel walls 4 and 5 delimiting the channel 6 are axially symmetrical in cross section to the radial R.
- the ends of the flexible plate 3 inserted into the channel 6 protrude beyond the rubber blanket 2.
- the rubber blanket 2 itself is not inserted into the channel 6, but rather forms a narrow slot above the channel opening 7 or preferably abuts against one another via the channel opening 7.
- the clamping device for clamping the ends of the covering 2, 3 is formed by a clamping body 10 arranged in the channel 6 in combination with channel walls delimiting the channel.
- the channel walls are the channel walls 4 and 5 and a further channel wall 9, which each form a counter surface for the clamping body 10.
- the clamping body 10 is supported directly on this, the channel 6 between the enclosed channel walls 4, 5 and 9.
- the channel walls 4 and 9 are formed directly by the cylinder 1 itself.
- the channel wall 5 forms a filler 8, which is fixed to the cylinder 1, i. H. is not movable, connected, for example screwed.
- the channel wall 4 extends from the channel wall 9 flat to the boundary edge lv.
- the channel wall 5 extends from the channel wall 9 flat to the boundary edge 8n.
- the channel walls 4 and 5 each point at the same angle, which should be at least 30 ° and at most 45 °, obliquely to the radial R.
- the clamping body 10 is circular cylindrical. It is a composite body with a core 10i made of a core material and a jacket 10a made of a jacket material.
- the core material has a greater specific weight or a greater specific density than the cladding material.
- the jacket material is elastic and can for example be rubber or preferably a plastic, ie an elastomer. It has a hardness of 70 ⁇ 10 Shore, with the center value or values closer to the center value of 70 Shore being preferred.
- the clamp body 10 is supported directly on the channel walls 4, 5 and 9, i. H. with its surface it touches a counter surface formed by the channel walls 4, 5 and 9.
- the counter surface formed by the channel wall 4 is referred to as the first counter surface 4, the counter surface formed by the channel wall 5 as the second counter surface 5 and the counter surface formed by the channel wall 9 as the third counter surface 9.
- the support points of the clamping body 10 formed by the counter surfaces 4, 5 and 9 are over the circumference
- the total of three support points each have an angular spacing of less than 180 ° from one another, which already results from the advantageous triangular shape of the channel 6 selected in the exemplary embodiment. It is particularly advantageous if two adjacent support points, as in the exemplary embodiment, have the same angular distance.
- the clamping body 10 forms a clamping gap for the ends of the covering 2, 3 either with the first counter surface 4 or with the second counter surface 5.
- the clamping gap between the clamping body 10 and the first counter surface 4 is formed.
- the clamping gap is formed in the same way between the clamping body 10 and the second counter surface 5. Due to its round surface, the inflow body 10 forms with the first counter surface 4 a funnel which opens to the channel opening 7 and which facilitates the insertion of the ends of the covering 2, 3.
- the funnel is shaped in such a way that there is no risk of inhibition when the string ends are inserted.
- the surface of the embossing body forming the clamping gap has a large radius of curvature. If the clamping body 10, as preferred and carried out in all exemplary embodiments, circular in cross section, this means that it should have a large outside diameter. On the other hand, a small cross section of the channel 6 is advantageous. The width of the channel opening 7 which can no longer be changed after the filling piece 8 has been inserted should be as small as possible in order to minimize the cylinder runout.
- the clamping body of the invention for example that of the first exemplary embodiment and the further exemplary embodiments, has a radius of curvature of at least 7 mm, preferably at least 10 mm, on its surface forming the clamping gap.
- the upper limit for the radius of curvature is less critical. However, the radius of curvature should not be more than 20 mm.
- the jacket 10a is sufficiently thick that, due to its material elasticity, it can deflect over the entire circumference of the male body 10 by the sum of the thicknesses of the two ends of the covering 2, 3.
- the clamping device of the first exemplary embodiment has no further possibilities for deflection, since the support points for the clamping body 10 are rigidly formed directly by the channel walls, namely the counter surfaces 4, 5 and 9.
- the clamping body 10 should have the largest possible mass and therefore the highest possible proportion of core material in order to increase the clamping force when the cylinder 1 is rotating.
- the jacket 10a has a circumferential uniform thickness of at least 3 mm and at most 7 mm. In a preferred dimensioning example, the jacket 10a has a thickness of 5 mm and the core has a diameter of 15 mm.
- the clamping device shown in FIG. 2 comprises a clamping body 10 which is formed in a fully cylindrical manner from an elastic material, for example rubber or an elastomer.
- the elastic material may be the same material as that of the jacket 10a in the first embodiment.
- Figure 3 shows a clamping device of a third embodiment.
- the spring required for clamping the ends of the covering 2, 3 is formed by a clamping body 20 arranged in the channel 6.
- the cylinder 1, the filler 8 and the channel 6 correspond to the first embodiment and the second embodiment.
- the spring formed by the sealing body 20 is not material-elastic. Their resilience is based on formula elasticity. In cross section it essentially has the shape of a Greek “ ⁇ ” with a resilient arch 21 and two support feet 22.
- the arch 21 extends over the first counter surface 4 and the second counter surface 5 and is open towards the third counter surface 9
- An essentially circular-cylindrical arch 21 extends over most of the 360 ° of a closed arch, and the two ends of the arch 21, ie the two transition regions in which the arch 21 merges into the two support feet 22, are at a tight distance from the counter surface 9
- the support feet 22 are only in contact with the counter surface 9 with their tapering ends.
- the support feet 22 end in front of the inner edges of the channel 6, which the counter surface 9 forms with one of the counter surfaces 4 and 5.
- the support feet 22 can thus run along the counter surface 9 slide back and forth, which is advantageous for the compression of the clamping body 20.
- the clamping body 20 can therefore be twisted in two ways springs, on the one hand by a movement of the two ends of the arch 21 towards one another and on the other hand by a resilient movement of the arch 21 as a whole towards the counter surface 9.
- the spring movement that actually occurs when the ends of the covering 2, 3 are clamped results from a superimposition of both spring options.
- the elastic behavior of the embossed body 20 forming an open spring can be better adapted to the function.
- FIG. 4 shows a clamping device according to a fourth exemplary embodiment; in the fourth exemplary embodiment, a spring 15 directly forms the second counter surface 5, which lies opposite the clamping gap in the circumferential direction of the cylinder 1.
- the channel 6 of the fourth exemplary embodiment is polygonal with a total of five each flat channel walls, of which ⁇ however only the channel walls 4, 5 and 9 form the support points and thus the numbered counter surfaces 4, 5 and 9 for the IDemm Stress 25, n Grande a triangular cross section of the channel 6 can also be assumed in the fourth exemplary embodiment.
- the formation of the channel 6 with more than 2 inner edges in cross section facilitates production, since those to be formed by material processing
- Inner edges can be rectangular or obtuse. For the function of the clamping device, however, this alone does not result in any difference from the first, second and third exemplary embodiment.
- the inhibitor 25 of the fourth exemplary embodiment is a rigid body that is not resilient.
- the clamping body 25 can in particular be a steel body. It is circular cylindrical and full in cross section.
- the counter surface 9, which again forms the channel bottom, serves at the same time as a guideway for the clamping body 25, which is moved transversely when clamping the ends of the covering 2, 3.
- the clamping body 25 moves on the Counter surface 9 rolling 0 and / sliding away from the first counter surface 4 and into the second counter surface 5.
- the second counter surface 5 is formed by a material-elastic spring 15.
- the spring 15 is an insert made of an elastic material, for example rubber or an elastomer, which is inserted into a recess in the channel wall 5.
- the depression and the insert 15 are shaped in such a way that the insert 15 fits seamlessly into the flat channel wall 5 and, in particular, ends flush with it, forming the counter surface 5.
- the insert 15 is a strip which extends at least over the part of the axial length of the channel 6 which the clamping body 25 occupies or which are arranged axially next to one another take several clamping bodies 25, n embodiment 15 is rectangular in cross-section and a total of a cuboid.
- the insert 15 has a thickness and a width measured along the channel wall 5 which are sufficient for the insert 15 to be able to deflect to such an extent that the clamping body 25 extends from the first counter surface 4 along the counter surface 9 by the thicknesses of the two ends of the covering 2, 3 can move away.
- the elastic restoring force of the insert 15 presses the clamping body 25 against the ends when the covering 2, 5 3 is drawn in.
- the displacement of the clamping body 25 is indicated by a straight line parallel to the cylinder radial R.
- the shifted focus is labeled SP.
- the formation of the spring 15 in one of the walls of the channel 6 is advantageous for the rotatability of the clamping body 25 and this again is advantageous for the retraction and that
- the opening body 25 can have an advantageously large weight and, finally, its manufacture is particularly simple.
- the filler 8 forms the carrier for the insert 15.
- the creation of the spring by means of the insert 15 is therefore particularly simple.
- Figure 5 shows a clamping device of a fifth embodiment, which is derived from that of the fourth embodiment.
- an insert 14 forms the first counter surface 4 forming the clamping gap with the clamping body 25.
- the insert 14 corresponds to the insert 15 of the fourth exemplary embodiment.
- the combination of the two exemplary embodiments of FIGS. 4 and 5 further shows that the clamping devices of the two exemplary embodiments are also inherently invariant in terms of the direction of rotation, i. H. in both exemplary embodiments, the ends of the covering 2, 3 can be clamped between the clamping body 25 and optionally either the first counter surface 4 or the second counter surface 5.
- FIG. 6 shows a sixth exemplary embodiment derived from the fourth and fifth exemplary embodiments.
- a material-elastic insert 14 forms the first counter surface 4 and another material-elastic one I insert 15 the second counter surface 5.

- a further filler could form the channel wall 4 or at least a part comprising the insert 14 and so as
- Carrier for use 14 serve.
- the spring is formed in or on a channel wall delimiting the channel 6, the spring could also be formed in or on an outwardly facing bottom surface, such as the counter surface 9, it is preferred if the spring or the plurality
