- first roller, second roller and tube can be combined as desired. It is crucial that the tube or its wall in a relative movement between the contour and the forming roller is moved through.
- the first and second directions of rotation are opposite, and the speed of rotation may be the same or different.
- a first variant includes supporting the tube in a freely rotatable manner while the first and / or second roller is being rotated.
- the tube is driven by the at least one driven roller by friction, so it rotates opposite to the at least one driven (about first) roller and optionally in the same direction as the at least one further (about second) roller.
- the at least one further roller is either carried along by friction, but can alternatively also be rotated in the corresponding direction of rotation.
- the tube is held in place while both the contour and form rollers are driven in the corresponding direction of rotation, thus rotating (counter-rotating) around the fixed tube.

- the separation occurs during molding. It is preferred that the separation is not carried out in a separate step, for example by cutting, but by the molding itself. The tubing is so overstressed at the small radii of the outer contour of a roller that it fails to separate the sealing ring from the remaining tube or . comes to the neighboring sealing rings. By saving an additional cutting step, manufacturing can be simplified and accelerated.
- the molding includes an initial molding and a final molding, and the separation is between molding and molding.
- initial molding is performed with only deformation of the pipe section to be molded to the seal ring.
- the pipe section is controlled overstressed by progressive deformation at the edge portions of the sealing ring to be formed, so that the sealing ring or the sealing rings are separated from the residual pipe or from each other.
- the deformation is then continued with the separated sealing ring (s) until the desired final shape is achieved, which substantially corresponds to the remaining space between the contour of the contour roller and the contour of the forming roller.
- separation occurs before or after molding.
- the separation can also take place outside of the molding process. Should be due to the material properties of the pipe a reliable Can not achieve separation by the molding alone, this can be compensated by subsequent separation.

- the method includes axially upsetting the tube. This is preferably ensured by movable flanges at the two outer ends of the tube (movement in the axial direction of the tube). As a result of the fact that the movement toward one another is superimposed by an upsetting movement, the tube is "unfolded” and pressed into the intermediate spaces of the shaping and contouring roller. that the forming process is not achieved by plastic deformation of the tube but material is postponed. This has the effect that the wall thickness of the tube is kept as constant as possible (or homogeneous).
- it is also conceivable to achieve the compression movement by means of an additional, superimposed process, such as, for example, internal or external high-pressure deformation, using a liquid medium or else a highly elastic or flowing medium, such as rubber.
- the pressure can be applied both from inside and outside, with the deformed tube then dodging outwards or inwards. In this case, an axial shortening or compression occurs.

- a roll commonly referred to as a "coil” separates suitable sheet metal pieces (blanks) .
- blades which may be single or multilayer
- a welding process such as laser welding or plasma welding
- a tubular precursor which has a defined shape, a defined texture (rolling direction), defined diameters (inside and outside), a defined wall thickness (but may also vary in places) and a characteristic joint.
- the characteristic features of the precursor can also be determined on the later end product.
- the sheet is unwound from a coil, optionally to the appropriate one
- the ends are connected to a closed tube.
- a welding method such as laser welding or plasma welding is used.
- an endless tubular precursor is available, which also has a defined shape, a defined texture (rolling direction), defined diameters (inside and outside), a defined wall thickness (but may also vary in places) and a characteristic joint. This means that the characteristic features of the precursor (more or less) can also be determined on the later end product.
- tubes made of single-layer sheets it is also possible to use tubes of several layers.
- a spiral wound pipe or "composite sheet” pipe such as aluminum clad sheet or coated sheet may also be used.
- the entire tube is first formed in a manufacturing step, then separated into individual rings or torn and finally formed.
- two contoured rolls are used.
- the tube or intermediate product of defined length is plugged and guided or held with respect to the axial and radial position.
- the at least one second contoured roller is moved in the direction of the at least one first roller.
- the two profile contours of the contoured rollers are pushed into one another, wherein the gap between the two contours defines the shape of the later sealing ring.
- the tube or its wall is thereby moved through in a relative movement between opposing rollers and thereby subjected to the molding process. It is possible, in each case only actively drive or rotate one element of the three elements concerned contour roller, tube and forming roller, wherein one or two further elements are passively taken by the friction.
- the molding roll can be driven, wherein the contour roller and tube are taken freewheeling.
- the contour roller can also be driven in addition. It is also possible to drive all three elements.
- the forming device rotates while the tube is held rotationally fixed in position. Both contour and form rollers are driven (in opposite directions), thus moving around the fixed pipe. This embodiment is suitable for a kind of "endless" production, in which the quasi “endless” tube is only advanced, but not rotated.
- another criterion of the two contours is that the raised portions (the "peaks" of the contour) of the outer contour of one roller have larger (curvature) radii than those of the raised portions of the other roller Outer contour with larger radii, the contour roller, and the roller with the contour with the smaller radii, the forming roller.
- the task of the contour roller is to provide the sealing ring with a defined contour over which it is shaped. This means that, in the case of an inwardly open sealing ring, the contour roller represents the radius facing the inner side and, when the sealing ring is open to the outside, the radius facing the outer side.
- the task of the forming roller is to form a defined sealing ring on the contour roller or to roll and on the other at defined locations (the small Radii of the forming roll) to induce such high stresses in the tubing that the material is overstressed at these locations and fails.
- the process is performed in three steps. First, the tube is formed and thus rolled many seals next to each other, but the tube also stiffened or stabilized. By further moving the rollers towards each other, the sealing rings are further shaped until they are separated at the small radii of the forming roller. Finally, the now individually present sealing rings are formed by further successive moving the rollers until they have reached their desired final contour. The steps of this process therefore involve initial molding, separation and final molding.
- the tube is first formed from one end or possibly also from both ends in continuously successive production steps - sealing ring for sealing ring - then separated or torn and finally formed.
- two (or possibly more) contoured rolls are used.
- the basic production sequence, the initial molding, the separation and the final molding can be maintained here.
- the manufacturing process according to the invention can result in a slimming of the sealing ring ends, which can be detected on the end product. Furthermore, this production results in a characteristic separation or breaking edge. If the sealing ring is not subjected to a subsequent heat treatment, the separating or breaking edge can also be recognized on the end product.
- the pipe must be "compressed” during the manufacturing process, and the plant must then also be able to compress or compress the pipe in an axial direction high-pressure Forming or rubber molding process, which allow a deformation without reducing the wall thickness at the ends.
- the method according to the invention can also be carried out in variants or modifications or in sub-steps. To this end, the following two examples are mentioned.
- the process step of the separation is not sufficient to separate the tube in a single pass into individual sealing rings.
- an additional manufacturing step has to be introduced, in which a cutting roll with an adapted pitch, but with very small, i. sharp radii, is used. In this way, the pipe is pre-formed or trimmed before molding, so that the molding roll during the actual manufacturing process can achieve the separation or separation of the sealing rings.
- a complete cutting is alternatively also possible, which can be done before or after the molding process.
- Fig. 1 shows various steps of a method according to the invention.
- the tube 2 and the sealing ring 1 is shown in cross section.
- the contour roller in the figure on the left
- the forming roller in the figure each right
- step (a) a tubular precursor 2 is arranged and held between the contour 16 of a contour roller and the contour 14 of a forming roller.
- the forming roller is moved in the direction of the contour roller. Before contact of the contour 16 of the contour roller with the tube 2 no deformation has yet occurred.
- step (b) by further moving the forming roll in the direction of the contour roll, the profile of the sealing ring to be formed is formed in the pipe 2.
- the tube 2 is still in one piece.
- step (c) the situation is shown after the sealing ring 1 has been separated by further deformation of the tube 2. By overloading the material at the small radii of the molding roll, the sealing ring has been torn or broken.
- step (d) the sealing ring has assumed its final shape by molding.
- the sealing ring was his Form given by the remaining space between the contour 14 of the forming roller and the contour 16 of the contour roller. It should be noted that, as a rule, the ring shape will not exactly match the remaining space between the contours, but the sealing ring will slightly relax again at the latest after opening the rollers (material-dependent and contour-dependent springback behavior).
- FIG. 2 different geometries of sealing rings according to the invention are shown in cross section.
- a sealing ring of V-shape is shown having a constant material thickness.
- Such sealing rings can be produced for example by a method as in Example 2 explained above.
- sealing rings are also shown with V-shape, which have different degrees of tapering in the direction of the sealing surfaces. This property may be desirable because the taper distributes the internal stresses more evenly over the entire cross-section, which benefits the spring behavior and the fatigue or fatigue properties. In addition, it can be adjusted on how large the sealing edge should be and thus how high the sealing or line force will be.
- these sealing rings can be produced with tapered sealing surfaces.
- due to the induced in the material direction train to these tapers may occur before cracking or breaking occurs due to material failure.
- Fig. 3 serves to illustrate the arrangement of the radii of the respective outer contours.
- the direction of movement of the rollers during the molding process is indicated by arrows, the tube is not shown here for clarity.
- the radii of the raised portions ie, the portions which project furthest toward the pipe are first in contact with the pipe wall occur
- the dashed circle G the radii of the raised portions
- the radii of the raised portions are smaller, as indicated by the dashed circles K. In this case, therefore, this roller is the forming roller.
- the tube 2 can be free-running, that is not actively driven.
- the tube 2 is also co-rotated clockwise.
- the roller 6 must also not be driven, but can run along (counterclockwise). But it can also be actively driven.
- Other combinations of driven and only revolving elements are possible.
- FIG. 5 shows by way of example and schematically a device for carrying out the method according to the invention.
- a tubular precursor 2 is arranged on a contour roller 4.
- a supply device 8 is provided which, for example, by driving up to the tube and advancing the same under Reibungskraft gleich enables transport.
- an associated separate holding or abutment device 10 is shown, which can be applied to the end face of the tube 2 (indicated by arrow) to hold it.
- a forming roller 6 can be moved by a drive device 12 in the direction of the contour roller 4.
- the tube 2 can be set in a rotation in a first direction of rotation (left arrow).
- the forming roll 6 may be frictionally traversed while being pressed onto the pipe 2, or may be rotated by a drive means, also not shown, into rotation in an opposite direction of rotation (right arrow) to minimize friction with the pipe 2.
- Fig. 6 shows an embodiment of the invention, in which the molding operation of the sealing rings in several stages (here three) takes place.
- an inner roller 4 is provided with a uniform outer contour, on which a tube 2 (dashed lines) is pushed.
- a first outer roller 6 ' is moved towards the roller 4, and an intermediate shape of the sealing ring or rings to be formed is formed by relative movement of the tube wall between the rollers 4, 6' as described above.
- a further intermediate shape is then formed between the second outer roller 6 "and the inner roller 4.
- the shape of the sealing ring is finally produced between a third outer roller 6"'and the roller 4.
- the shaping could also take place between roller 6 "and roller 4, wherein roller 6"'is designed as a cutting roller.
- roller 6 'could be designed as a cutting roller for cutting sealing rings, wherein the sealing ring or the sealing rings of the other rollers 6 "and 6"' shaped and separated becomes.
- Fig. 7 shows an embodiment of the invention in which the molding operation of the sealing rings takes place in two stages.
- the tube 2 is formed between rollers 4 'and 6'.
- the pipe section is passed on to the second stage, for example by feeding in the axial direction.
- the final shape of the sealing ring then receives between the other rollers 4 "and 6".
- each of the inner and outer rollers may also be designed as a partial contour on an axially continuous roller instead of a separate roller. This variant lends itself, for example, to a quasi-endless production, since in it the tube merely has to be pushed axially one step further, whereby all steps can operate in parallel at different stages of operation.
