Description

[Technical Field]

[0001] The present invention relates to an adjustment device for a coating device for partially coating a material web, to a coating device for partially coating a material web, and to a coating method.

[0002] For example, a material web is coated during membrane production to produce a plastic film. Similarly, in the production of electrodes, an electrode or at least an electrode precursor can be produced by coating a metal film.

[0003] In such coating processes, the coating material is applied using a roller to a web of material, which is essentially endless and often has a length of several hundred meters to several kilometers.

[0004] Between each coated section, there can be an uncoated section, i.e. the material web can be coated partially or intermittently. Corresponding coating methods and coating devices are known, for example, from DE 10 2014 118524 ​​A1 or EP 2 922 126 A1.

[0005] For intermittent or partial coating, the coating unit must be moved back and forth in one direction, usually perpendicular to the material web. To apply paint to the sections to be coated, the coating unit must usually be located close to the material web, but if paint is not to be applied to the sections not to be coated, the coating unit must be, or at least should be, moved away from the material web.

[0006] The speed and acceleration of the corresponding coating unit can have a negative effect on the quality, in particular the accuracy of compliance with a specified coating dimension or section, especially at high web speeds.Known processes are therefore limited to relatively low material web feed speeds, so that coating the material web takes a relatively long time.

[0007] Known adjustment mechanisms or devices also adjust the coating unit relatively unsteadily or oscillately, which also adversely affects the quality of the coating. Additionally, a fast adjustment with high responsiveness is desirable.

[0008] It is therefore an object of the present invention to provide a conditioning device, a coating device and a method which allow a material web to be flexibly and partially coated even at very high feed speeds of the material web. The conditioning unit according to the invention is also characterized by a high level of smoothness at high conditioning speeds.

[0009] This object is achieved by a conditioning device according to claim 1, a coating device according to claim 7 and a method according to claim 11. Advantageous embodiments are the subject of the respective dependent claims.

[0010] A first aspect of the present invention relates to an adjustment device for a coating device, the adjustment device comprising a cam and an adjustment element in contact with the cam and adjustable upon rotation of the cam, the adjustment device having a receptacle for a roll, roller or coating device, the adjustment element and the receptacle being mechanically coupled such that adjusting the adjustment element adjusts the receptacle.

[0011] The cam and the adjusting element can achieve a mechanically stable, error-free adjustment. The adjusting unit operates very smoothly. The adjusting element can accelerate quickly and / or have a high adjustment speed. This allows the adjusting unit to have a high level of responsiveness.

[0012] The adjustment element can roll relative to the cam. The adjustment element and / or the cam can be arranged such that the adjustment element can roll relative to the cam. The adjustment element and / or the receptacle can be linearly adjustable. For example, the adjustment device can have one or more linear guides for linear adjustment of the adjustment element and / or the receptacle.

[0013] The cam can have a transition section. The diameter of the cam can change along the transition section so that the adjustment element can adjust as it rolls along the transition section. Alternatively or additionally, the cam can be mounted eccentrically. When the cam is mounted eccentrically, the adjustment element can adjust, or become adjusted, as the cam rotates.

[0014] The transition section can be disposed on the surface of the cam at an angle ranging from 10 to 20 degrees, preferably 15 degrees. Alternatively or additionally, the diameter of the cam can vary along the transition section by 0.1 to 5 mm, preferably 0.5 to 2 mm, and particularly preferably 1 mm.

[0015] The adjustment device may have a stopper. The stopper may specify a maximum adjustment path of the adjustment element and / or receptacle. In some embodiments, the maximum adjustment path may be 5 mm or less, preferably 2 mm or less, and particularly preferably 1 mm or less. The stopper may be arranged in such a way that it may contact the adjustment element and / or receptacle when the adjustment element and / or receptacle is being or will be adjusted by the maximum adjustment path. The stopper allows the adjustment path of the adjustment element to be set and / or specified accurately and precisely.

[0016] For example, a first point on the adjustment path corresponding to no adjustment or minimal adjustment can correspond to a first position (or a third position) of the receptacle and / or a first position (or a third position) of an object, such as a support roller or a coating unit, received or mounted within the receptacle. For example, a second point on the adjustment path corresponding to maximal adjustment can correspond to a second position (or a fourth position) of the receptacle and / or a first position (or a fourth position) of an object, such as a support roller or a coating unit, received or mounted within the receptacle.

[0017] The cam may have a diameter of 70 to 90 mm, preferably 75 to 85 mm, and particularly preferably essentially 80 mm. Alternatively or additionally, the diameter of the adjustment element may be 40 to 55 mm, preferably 25 to 50 mm, and particularly preferably 47 mm. In some embodiments, if the cam has a thickness, the diameter of the cam may be measured or defined without the thickness. However, in some embodiments, the diameter of the cam includes the thickness.

[0018] The cam and / or adjusting element may be plasma-nitrided, which may ensure that the cam and / or adjusting element have a long service life and / or that the adjusting unit requires little maintenance.

[0019] A further aspect of the invention relates to a coating apparatus for partially coating a material web, the coating apparatus having first and second support rollers for guiding the material web, and a first coating unit for applying a first coating material and a second coating unit for applying a second coating material to the material web, the first support rollers and the first coating unit forming a first gap and the second support rollers and the second coating unit forming a second gap through which the material web is guided, the coating apparatus having first and second adjustment devices. The coating apparatus has a first adjustment device configured to adjust the first support roller and / or the first coating unit between a first position and a second position where the first gap is smaller than in the first position, and a second adjustment device configured to adjust the second support roller and / or the second coating unit between a third position and a fourth position where the second gap is smaller than in the third position, so that when the material web is guided through the first gap and the second gap, the material web can be coated alternately by the first coating unit and the second coating unit.

[0020] The coating apparatus has a first coating unit and a second coating unit that are independently adjustable, so that a section of the material web can be or will be coated by one coating unit when another section of the material web is not or will not be coated by the other coating unit. The first coating unit may coat only the second section, and the second coating unit may coat the section omitted by the first coating unit, or vice versa. Because the coating apparatus has a second coating unit, the time that one coating unit is or will be adjusted can be or will be used for coating by the other coating unit.

[0021] Thus, the coating apparatus according to the present invention allows partial or intermittent and / or alternating coating of a material web at high feed rates of the material web. Compared to known coating units and methods, some embodiments of the coating apparatus according to the present invention can achieve a 3-5 times increased feed rate of the material web with good coating quality. While known coating methods and coating apparatuses can coat webs at feed rates of about 60-80 m / min, the coating apparatus according to the present invention (and corresponding methods according to the present invention) can coat material webs at feed rates of 200-300 m / min or even higher.

[0022] In some embodiments, the feed rate is so high that a point on the material web can traverse the distance between the first and second coating units in, for example, just 0.1 seconds or less, for example, 0.5 seconds or less, for example, 0.8 seconds or less, or, for example, 2 seconds or less. The material web can be coated with high coating quality despite the high feed rate due to the adjustment unit that allows for rapid adjustment and the first and second coating units that can coat sections of the material web alternately. Additionally, a compact design of the coating apparatus is possible.

[0023] The first and / or second adjustment device may be or may include the adjustment device described above. The second gap may be arranged behind the first gap in the guiding direction of the material web.

[0024] In other words, when the material web is guided by the first support roller or guided through the first gap, in the second position the first coating unit applies or can apply the first paint to the material web, and in the first position the first coating unit cannot or does not apply the first paint to the material web.

[0025] When the material web is guided by the second support roller or is guided through the second gap, in the fourth position the second coating unit applies or can apply the second paint to the material web, and in the third position the second coating unit cannot or does not apply the second paint to the material web.

[0026] In some embodiments, the first and second coating materials may be the same and / or have the same ingredients and / or the same composition. In some other embodiments, the first and second coating materials may be different and / or have different ingredients and / or different compositions. The material web may be or include a metal film. The coating material may be or include an electrode precursor material.

[0027] The first position can correspond to minimal or no adjustment of the first adjustment unit, the first support roller, and / or the first coating unit. The third position can correspond to maximum adjustment of the first adjustment unit, the first support roller, and / or the first coating unit. The second position can correspond to minimal or no adjustment of the second adjustment unit, the second support roller, and / or the second coating unit. The fourth position can correspond to maximum adjustment of the second adjustment unit, the second support roller, and / or the second coating unit.

[0028] The conditioning device can be mechanically coupled to the corresponding coating unit and / or the corresponding support roller.

[0029] When the first support roller and / or the first coating unit is in the first position, the second support roller and / or the second coating unit can be in the fourth position, and / or when the first support roller and / or the first coating unit is in the second position, the second support roller and / or the second coating unit can be in the third position, such that one coating unit coats every two sections of the coating target, and the other coating unit coats the omitted section of the coating target.

[0030] The first coating unit and / or the second coating unit may be or may include a slot die, a coating roller, and / or a gravure roller. The first coating unit and / or the second coating unit may be configured to apply the coating material via indirect coating. Alternatively, the first coating unit and / or the second coating unit may be configured to apply the coating material via direct coating.

[0031] The first support roller can be adjustable by a first adjustment device, the second support roller can be adjustable by a second adjustment device, and the first and second coating units can be non-adjustable. The first and / or second coating units can be fixedly positioned on or within the coating apparatus. In the second position, the first support roller can be further spaced from the first coating unit than in the first position, and in the third position, the second support roller can be further spaced from the second coating unit than in the fourth position.

[0032] When one or more of the support rollers are adjusted by one or more corresponding adjustment units, the material web can be adjusted relative to the corresponding coating unit. The corresponding coating unit can be permanently arranged, stored, and / or attached on or within the coating apparatus. When the coating apparatus is fixedly arranged and / or not adjusted, the corresponding acceleration of the corresponding coating material due to adjustment by the adjustment unit can also be eliminated, thereby achieving good coating quality.

[0033] In some embodiments, it may be intended to control and / or adjust the coating apparatus and / or the first coating unit and / or the second coating unit in such a way that paint can or will be applied to a predetermined section of the material web and / or that paint cannot or will not be applied to a predetermined section of the material web.

[0034] The material web may be placed on the first support roller and / or may be supported by the first support roller when the material web is guided through the first gap. The first coating unit may apply the first coating material to the material web, for example, by contacting and / or touching the material web. Alternatively or additionally, the first coating unit may apply the first coating material to the material web, for example, by bringing the first coating unit close to the material web, at least to the extent that the material web or the first coating material can be applied.

[0035] The material web may rest on the second support roller and / or may be supported by the second support roller when the material web is guided through the second gap. The second coating unit may apply the second coating material to the material web, for example, by contacting and / or touching the material web. Alternatively or additionally, the second coating unit may apply the second coating material to the material web, for example, by bringing the second coating unit close to the material web, at least to the extent that the material web or the second coating material can be applied.

[0036] The first and / or second coating unit may be or include a gravure roller. Alternatively or additionally, the first and / or second coating unit may be or include an application roller. The first and / or second coating unit may include a metering roller that can contact the application roller and / or supply coating material to the application roller.

[0037] The coating apparatus can have bearings in which and / or with which the first and / or second coating units can be mounted, for example, if the first and / or second coating units are or include rollers or rolls. The coating apparatus can have support roller bearings in which or with which support rollers can be mounted. The receptacle of the adjusting device can be, form, or include a bearing or receptacle for a roller or cylinder. The adjusting device can be configured to adjust the rotation axis of the first and / or second coating units, for example, if the first and / or second coating units are rollers and / or rolls, respectively. Alternatively or additionally, the adjusting device can be configured to adjust the rotation axis of the first and / or second support rollers.

[0038] In some embodiments, at least one drying device may be provided after the coating device, for example in the conveying direction of the material web, and may be configured to dry the applied coating material.

[0039] Yet another aspect of the present invention relates to a method for partially coating a web of material, comprising the steps of: (a) providing a coating of a material web;

[0040] a) passing the material web through a first gap formed by a first support roller and a first coating unit, and passing the material web through a second gap formed by a second support roller and a second coating unit; b) adjusting the first support roller and / or the first coating unit from the first position to the second position using the first adjusting device, the first gap being smaller at the second position than at the first position; and adjusting the second support roller and / or the second coating unit from the fourth position to the third position using the second adjusting device, the second gap being smaller at the fourth position than at the third position; c) applying a first coating material to the material web guided through the first gap using a first coating unit; d) adjusting the first support roller and / or the first coating unit to a first position using a first adjusting device, and adjusting the second support roller and / or the second coating unit from a third position to a fourth position using a second adjusting device; and e) applying a second coating material to the material web guided through the second gap using a second coating unit.

[0041] The second gap can be located after the first gap in the guide direction of the material web. One, some, or all steps of the method can be performed or can be performed using the coating apparatus described above. The coating apparatus described above can be configured to perform one, some, or all steps of the method.

[0042] Steps b) to e) can be repeated.

[0043] The second coating may be applied when the first coating is applied without the second coating, and / or the first coating may be applied when the second coating is applied without the first coating.

[0044] Step d) can be performed after a specified time interval following step b) and / or step c). In some embodiments, the predetermined time interval can be selected depending on the feed rate of the material web. Alternatively or additionally, the predetermined time interval can be selected depending on the dimensions of the section of the material web to be coated. The dimensions can include or be, for example, the area, length, and / or width of the material web and / or section.

[0045] The first coating material is or can be applied in or on a first section of the web of material, and the second coating material is or can be applied in or on a second section of the web of material, where the first and second sections of the web of material do not overlap or only partially overlap.

[0046] The first section can be disposed on a first side of the web of material and the second section can be disposed on a second side disposed opposite the first side.

[0047] The material web may be or include a metal film. The coating material may be or include an electrode precursor material.

[0048] The invention will be further explained with reference to the following figures: [Brief explanation of the drawings]

[Figure 9] 1 illustrates a further exemplary embodiment of a coated material web. DETAILED DESCRIPTION OF THE INVENTION

[0050] FIG. 1 shows an exemplary embodiment of a coating apparatus 1 according to the present invention. The coating apparatus 1 includes a first support roller 2 and a first coating unit 3. The first coating unit 3 can be or include a coating roller or a gravure roller. In some embodiments, the first coating unit 3 can be or include a slot die. A first gap 14 is formed between the first support roller 2 and the first coating unit 3. A material web 4 can be or will be guided through the first gap 14. When the material web 4 is or will be guided through the first gap 14, the material web 4 can be or will be guided and / or supported by the first support roller 2.

[0051] The coating apparatus 1 further includes a second support roller 2.2 and a second coating unit 3.2. The second coating unit 3.2 can be or can include a coating roller or a gravure roller. In some embodiments, the second coating unit 3.2 can be or can include a slot die. A second gap 14.2 is formed between the second support roller 2.2 and the second coating unit 3.2. The material web 4, which can be guided through the first gap 14, can be or will be guided through the second gap 14.2. When the material web 4 is or will be guided through the second gap 14.2, the material web 4 can be or will be guided and / or supported by the second support roller 2.2.

[0052] The coating apparatus 1 has a first adjustment device 6. The first adjustment device 6 can be configured to adjust the first support roller 2 and / or the first coating unit 3 between a first position and a second position. When the first support roller 2 and / or the first coating unit 3 are in the second position, the first coating unit 3 can apply the first coating material 5 to the material web 4 when the material web 4 is guided or will be guided into the first gap 14 and / or between the first support roller 2 and the first coating unit 3. In the first position, the first support roller 2 and / or the first coating unit 3 can be arranged such that the first coating unit 3 does not and / or cannot apply the first coating material 5 to the material web 4.

[0053] The coating apparatus 1 further includes a second adjustment device 6.2. The second adjustment device 6.2 can be configured to adjust the second support roller 2.2 and / or the second coating unit 3.2 between a third position and a fourth position. When the second support roller 2.2 and / or the second coating unit 3.2 are in the fourth position, the second coating unit 3.2 can apply the second coating material 22 to the material web 4 when the material web 4 is or will be guided in the second gap 14.2 and / or between the second support roller 2.2 and the second coating unit 3.2. In the third position, the second support roller 2.2 and / or the second coating unit 3.2 can be positioned such that the second coating unit 3.2 does not and / or cannot apply the second coating material 22 to the material web 4.

[0054] The second support roller 2.2 may have some, some, or all of the features and / or advantages of, and / or may be structurally identical to, the first support roller 2. The second coating unit 3.2 may have some, some, or all of the features and / or advantages of, and / or may be structurally identical to, the first coating unit 3. The second conditioning device 6.2 may have some, some, or all of the features and / or advantages of, and / or may be structurally identical to, the first conditioning device 6.

[0055] The first coating unit 3 and / or the first support roller 2 can be or are adjusted periodically and / or repeatedly between the first and second positions. After a predetermined time interval has elapsed, the first coating unit 3 and / or the first support roller 2 can be or are adjusted from the second position to the first position, and / or vice versa. The second coating unit 3.2 and / or the second support roller 2.2 can be or are adjusted periodically and / or repeatedly between the third and fourth positions. After a predetermined time interval has elapsed, the second coating unit 3.2 and / or the second support roller 2.2 can be or are adjusted from the fourth position to the third position, and / or vice versa.

[0056] In some embodiments, the predetermined time interval can be selected depending on the feed rate of the material web 4. Alternatively or additionally, the predetermined time interval can be selected depending on the dimensions of the section of the material web 4 to be coated. This can result in partial and / or intermittent coating of the material web. "Intermittent" can mean partial or limited-time coating. The adjustment and / or position of the first coating unit 3, the second coating unit 3.2, the first support roller 2, and / or the second support roller 2.2 can be, or will be, controlled, for example, to coat and / or not coat predetermined sections and / or sections of predetermined dimensions.

[0057] In some embodiments, the first support roller 2, the second support roller 2.2, the first coating unit 3, and / or the second coating unit 3.2 can be or will be adjusted in the adjustment direction V or against the adjustment direction V. In some embodiments, only the coating unit 3 can be or will be adjusted, for example, in the adjustment direction V or against the adjustment direction V. In some embodiments, only the first support roller 2 and / or the second support roller 2.2 can be or will be adjusted, for example, in the adjustment direction V or against the adjustment direction V.

[0058] The first support roller 2 and / or the second support roller 2.2 can be mounted in or with their respective support roller bearings. The first support roller 2 and / or the second support roller 2.2 can be mounted, for example, in or with their respective support roller bearings so as to be rotatable about a rotation axis. The first coating unit 3 and / or the second coating unit 3.2 can be mounted in or with their respective coating unit bearings, for example, if the first coating unit 3 and / or the second coating unit 3.2 are or have coating rollers or gravure rollers, respectively. The first coating unit 3 and / or the second coating unit 3.2 can be mounted, for example, in or with their respective coating unit bearings so as to be rotatable about a rotation axis. The support roller bearings and / or the coating unit bearings can include, for example, one or more rolling bearings. For example, the roll necks of the first support roller 2, the second support roller 2.2 and / or possibly the first coating unit 3 and / or, in particular, the second coating unit 3.2, for example if these are or have coating or gravure rollers, may be mounted in or with respective bearings and / or rolling bearings.

[0059] Because the coating apparatus 1 has a first coating unit 3 and a second coating unit 3.2 that are independently adjustable, a section of the material web 4 can be or will be coated by one coating unit while another section of the material web 4 is not or will not be coated by the other coating unit. The first coating unit 3 coats only the second sections 18, 20, and the second coating unit 3.2 coats the section 23 omitted by the first coating unit, or vice versa. Because the coating apparatus 1 has a second coating unit 3.2, the time during which one coating unit is or will be adjusted can be or will be used for coating by the other coating unit.

[0060] The coating apparatus 1 allows partial or intermittent coating of the material web 4 at high feed speeds of the material web 4. The coating apparatus 1 (and the corresponding method) can coat the material web 4 partially or intermittently at feed speeds of 200-300 m / min or even faster.

[0061] In some embodiments, the feed speed can be so high that a point on the material web 4 can move the distance between the first coating unit 3 and the second coating unit 3.2, which may be downstream of the first coating unit in the transport direction F, in just 0.1 seconds or less, and in some embodiments, in 2 seconds or less, or in a time period between 0.1 and 2 seconds. The coating apparatus 1 is able to coat the material web 4 with high coating quality despite its high feed speed, thanks to the adjustment units 6, 6.2 that allow for rapid adjustment, and the coating units 3, 3.2 that can alternately coat sections 18, 20, 23 of the material web 4.

[0062] 2 to 4 show an exemplary embodiment of a conditioning device 6 according to the invention. When referring to a conditioning device 6 below, this can also mean the first conditioning device 6 and / or the second conditioning device 6.2 of the coating device 1 according to the invention.

[0063] In one or more embodiments, the adjusting device 6 can have a cam 8. The adjusting element 9 can be positioned such that the cam 8 can contact the adjusting element 9 at least when the cam 8 is rotating within a contact angle and / or angle range. The adjusting element 9 can roll relative to the cam 8. The adjusting element 9 can contact and / or roll on the cam 8 for each angle of rotation of the cam 8. Contact between the cam 8 and the adjusting element 9 can cause the adjusting element 9 to be adjusted or become adjusted.

[0064] The cam 8 may be cylindrical or disc-shaped in nature. In some embodiments, the cam may be part of a camshaft or may be located on or near the shaft.

[0065] The cam 8 can have a thickness d. The cam 8 can have one or more transition sections 13. Along the transition sections 13, the diameter of the cam 8 can vary. The transition sections 13 can have a transition profile. By changing the diameter of the cam 8, the adjustment element can be adjusted or become adjusted during rolling. The transition sections 13 can be positioned on the surface of the cam 8 at an angle range α of 10° to 20°. In some embodiments, the angle range α can be 15°. Along the transition sections 13, the diameter of the cam 8 can vary by 0.1 mm to 5 mm. In some embodiments, the diameter of the cam 8 can also vary by 0.5 mm to 2 mm, or 1 mm, along the transition sections.

[0066] The cam 8 can have a diameter D that can correspond to the theoretical cam diameter without increasing the thickness. The diameter D of the cam 8 can be 70 to 90 mm, preferably 75 to 85 mm, and particularly preferably 80 mm.

[0067] The adjustment element 9 can be cylindrical or disk-shaped. In some embodiments, the adjustment element can be part of the shaft or can be located on or near the shaft. The diameter of the adjustment element can be 40 mm to 55 mm, preferably 25 mm to 50 mm, and particularly preferably 47 mm.

[0068] The conditioning device 6 has a receptacle 10. The receptacle 10 may serve to support rolls or rollers, such as support rolls 2, 2.2 and / or coating or gravure rollers. In some embodiments, the receptacle 10 may generally serve to mount or hold the coating unit 3, 3.2.

[0069] The adjustment element 9 is mechanically coupled to the receptacle 10 in such a way that when the adjustment element is adjusted, the receptacle 10 is or will be adjusted as well. This means that the receptacle 10 can be adjusted by rotating the cam 8 by R. In some embodiments, the receptacle 10 and / or the adjustment element 9 can be linearly adjustable. For example, the adjustment device 6 can have one or more suitable linear guides. The adjustment direction V of the adjustment element 9 can correspond to or coincide with the adjustment direction V of the receptacle 10.

[0070] The cam 8 and the adjusting element 9 can achieve a mechanically stable, error-free adjustment. The adjusting unit 6 operates very smoothly. The adjusting element 9 can accelerate quickly and / or have a high adjustment speed, which allows the adjusting unit 6 to have a high level of responsiveness.

[0071] In at least one embodiment, the adjustment element 9 can alternatively or additionally act on and / or adjust the support roller bearing. When adjusting the adjustment element 9 by rotating the cam 8 by R, the support roller bearing and / or the support roller 2, 2.2 are or will be adjusted, for example in or against the adjustment direction V. In some embodiments, the support roller bearing can comprise and / or form the adjustment element 9.

[0072] In some embodiments, there may be multiple cams 8. In some embodiments, the receptacle 10 may have or be mechanically connected to a first adjustment element 9, and / or the support roller bearing may have or be mechanically connected to a second adjustment element 9. Each of the cams 8 may act on and / or contact a respective adjustment element 9.

[0073] When the cam 8 rotates R, it rolls on or off the adjusting element 9. The adjusting element 9 can have a contour of any suitable shape. The shape of the cam 8 and / or the adjusting element 9 can be selected and / or designed, for example, in such a way that vibrations when the cam 8 rotates can be avoided and / or at least reduced.

[0074] The cam 8 and / or the adjusting element 9 can be plasma nitriding treated. The plasma nitriding can extend the service life of the cam 8 and / or the adjusting element 9. The plasma nitriding can prevent and / or at least reduce wear of the cam 8 and / or the adjusting element 9. The cam 8 and / or the adjusting element 9 can have high strength.

[0075] In some embodiments, the cam 8 may be or is driven by a drive 14. The drive 14 may have, for example, one or more gears.

[0076] Depending on the rotation angle of the cam 8, the cam 8 and / or the adjustment element 9 can adjust the support roller 2, 2.2 and / or the coating unit 3, 3.2 between a first position and a second position and / or between a third position and a fourth position.

[0077] In some embodiments, a return device may be provided which can preload and / or press the cam 8 against the adjustment element 9 and / or press the adjustment element 9 against the cam 8. The return device can be or comprise, for example, a spring 12.

[0078] The adjustment device 6 may have a stop 11. The stop 11 may be configured to define a maximum adjustment path of the adjustment element 9. In some embodiments, the maximum adjustment path may be 5 mm or less, preferably 2 mm or less, particularly preferably 1 mm or less.

[0079] As shown in Figure 4, the cam 8 can be eccentrically mounted. Alternatively or additionally, the adjustment element 9 can be eccentrically mounted. The eccentric bearing allows the adjustment element 9 to adjust or be adjusted as it rolls. When the cam 8 and / or the adjustment element 9 are eccentrically mounted, the cam 8 may, in some embodiments, be circular and / or may or may not have a thickness d and / or a transition section 13.

[0080] In some embodiments, the cam 8 has been or will be adjusted in such a way that the adjusting device 9 can perform an essentially sinusoidal movement depending on the angle of rotation of the cam 8, as shown by way of example in Figure 5. Alternatively or additionally, the acceleration of the adjusting element 9 can also be sinusoidal.

[0081] Such a sinusoidal movement need not be limited to embodiments with eccentric bearings: for example, rotation of the cam 8 may generally result in a sinusoidal movement or sinusoidal course of the position of the adjusting element 9 depending on the angle of rotation of the cam 8.

[0082] In some embodiments, for example, the cam may have a transition section 13 along an angular range α of 15° in or relative to the direction of rotation R, and the adjustment device 9 may be adjusted or become adjusted by a stroke or adjustment of 0 to 1 mm as it rolls along the transition section 13. The stop 11 may be positioned so that the maximum adjustment path of the adjustment element 9 is 1 mm. The adjustment element 9 contacts the stop 11 at the maximum and / or minimum of its sinusoidal movement. In some embodiments, the adjustment speed of the adjustment element may be 0 m / s to 0.47 m / s. Other adjustment speeds and adjustment accelerations may occur depending on the size and / or weight of the adjustment element 9, the cam 8, and possibly the object housed in the receptacle 10, such as a roll, roller, or coating unit. The values ​​shown in FIG. 5 are exemplary. Other angular ranges α are possible, for example.
