[0001] The invention relates to a corrugated board production line for manufacturing corrugated board according to the preamble of claim 1. Furthermore, the invention relates to a coupling / uncoupling arrangement for a corrugated board production line. The invention also relates to a method for manufacturing corrugated board.

[0002] Corrugated board production lines are generally known from prior art due to obvious use. The prior art also discloses corrugated board production lines with printing devices for printing on a lamination web of a corrugated board web. A disadvantage of these known corrugated board production lines is often their extreme inflexibility. Long changeover times are frequently necessary to process different orders on the corrugated board production line.

[0003] The generic German patent DE 10 2015 218 333 A1 discloses a corrugated board production line with a corrugated board production line for producing a corrugated board web and a printing web printing line for producing a printed web, as well as a printing web transfer arrangement via which the printing web printing line is connected to the corrugated board production line. The corrugated board production line comprises a device for producing a single-sided laminated corrugated board web and a laminating web splicing device, as well as a heated drawing section through which the single-sided laminated corrugated board web and a laminating web are guided to form the corrugated board web. The laminating web splicing device comprises a splicing unit by means of which the printing web can be spliced ​​to the laminating web. The printing web printing line has an inkjet printing device for printing on the printing web and a printing web storage device, which includes a dynamic printing web storage unit and a printing web winding unit.A web diverter assembly is arranged between the web winding unit and the dynamic web storage unit to guide the web to the web winding unit or corrugated board production line. The web transfer assembly includes deflection rods. The single-sided laminated corrugated board can be connected to the laminating web of the corrugated board production line or printing line. This corrugated board system has proven its worth. However, its efficiency is not always optimal.

[0050] The endless cover web 14 is fed via a heating arrangement 21 and a deflecting roller 22 to the device 5 for producing a single-sided laminated endless corrugated board web 6, while the endless material web 20 is fed via a further deflecting roller 23 to the device 5 for producing a single-sided laminated endless corrugated board web 6.

[0051] The device 5 for producing a single-sided laminated endless corrugated board web 6 comprises a rotatably mounted first corrugating roller 25 and a rotatably mounted second corrugating roller 26 for producing an endless corrugated web 24 from the endless material web 20. The corrugating rollers 25, 26 are arranged in pairs and form a corrugating gap for guiding and corrugating the endless material web 20. Together they form a corrugating unit. The axes of rotation of the corrugating rollers 25, 26 run horizontally and perpendicularly to a conveying direction 27 of the endless material web 20.

[0052] To join the continuous corrugated web 24 with the continuous cover web 14 to form the single-sided laminated continuous corrugated board web 6, the device 5 for producing a single-sided laminated continuous corrugated board web 6 includes a glue application device 28 comprising a glue metering roller 29, a glue reservoir 30, and a glue application roller 31. To guide and glue the continuous corrugated web 24, the glue application roller 31 forms a glue gap with the first corrugating roller 25. The glue contained in the glue reservoir 30 is applied via the glue application roller 31 in the glue gap to the crests of the corrugation of the continuous corrugated web 24. The glue metering roller 29 rests against the glue application roller 31 and serves to form a uniform layer of glue on the glue application roller 31.

[0053] The endless cover sheet 14 is then joined with the endless corrugated sheet 24, which is coated with glue from the glue container 30, in the device 5 to produce a single-sided laminated endless corrugated board sheet 6.

A glue metering roller 43 of the gluing unit 41 rests against the gluing roller 42 to form a uniform layer of glue on the gluing roller 42. The single-sided laminated endless corrugated board web 6 is in contact with the gluing roller 42 with its corrugated web 24, so that the corrugation of the corrugated web 24 is coated with glue from the glue bath.

[0059] Downstream of the gluing unit 41, with respect to the conveying direction of the single-sided laminated endless corrugated board web 6, the corrugated board manufacturing arrangement 1 has a heating and pressure device (not shown) comprising a horizontally extending heating table. Adjacent to the heating table is an endless pressure belt guided by guide rollers. A pressure gap is formed between the pressure belt and the heating table, through which the single-sided laminated endless corrugated board web 6 and the endless laminating web 40 or printing web 4 are guided, forming the endless double-sided laminated corrugated board web.

[0060] Downstream of the heating and pressing device with respect to a conveying direction of the endless double-sided laminated corrugated board web, the corrugated board manufacturing arrangement 1 advantageously has a longitudinal cutting / creasing device (not shown) for longitudinal cutting and creasing of the endless double-sided laminated corrugated board web.

[0068] Downstream of the traction unit 53 with respect to the conveying direction 98 of the endless printing web 4 in the printing web / laminating web manufacturing arrangement 2, the printing web / laminating web manufacturing arrangement 2 has a corona pretreatment device 54 associated with the endless printing web 4. The corona pretreatment device 54 comprises a corona support roller 55 and at least one electrode 56 arranged adjacent to it. The endless printing web 4 is guided around the corona support roller 55. The endless printing web 4 runs through a corona pretreatment gap formed by the corona support roller 55 and the at least one electrode 56. In the corona pretreatment gap, the outer surface 51 of the endless printing web 4 is exposed to an electrical corona discharge, which leads to oxidation of its surface. This occurs particularly with a coated, continuous printing web 4. This results in higher dot gains per ink application or per printing.This improves the adhesion of a printing ink to the endless printing web 4.

[0069] Downstream of the corona pretreatment device 54 with respect to the conveying direction 98 of the endless printing web 4 in the printing web / laminating web manufacturing arrangement 2, the printing web / laminating web manufacturing arrangement 2 has a cleaning device 57 associated with the endless printing web 4, which cleans the endless printing web 4 at least on the outside.

The printing web buffer device 63 is designed as a dynamic printing web buffer device.

[0076] In the print web buffer device 63, the endless print web 4 is guided in a meandering pattern around several deflection rollers 64. At least one of the deflection rollers 64 can be displaced perpendicular to its axis of rotation, so that the length of the endless print web 4 buffered or stored in the print web buffer device 63 can be dynamically changed.

[0077] In the printing web buffer device 63, a pulling unit 65 is arranged on the output side, which includes at least one pulling roller for pulling the endless printing web 4 away from the printing web splicing device 44 in the printing web / laminating web manufacturing arrangement 2.

[0078] The print web buffer device 63 is connected, with respect to the conveying direction 98 of the endless print web 4 in the print web / lamination web production arrangement 2, to a print web winding device or storage device 66 of the print web / lamination web production arrangement 2.

[0082] The coupling / decoupling arrangement 76 has a frame 77 which includes two opposing vertically extending support walls 78.

[0083] In a first end region 79 of the frame 77, which faces the printing web splicing device 44 or the inkjet printing device 58, a laminating web guide roller 80 is rotatably mounted on the bearing walls 78.

[0084] The coupling / uncoupling arrangement 76 also includes a first adhesive tape application device 82, which is downstream of the laminating web guide roller 80 with respect to the laminating web conveying direction 81. The first adhesive tape application device 82 includes a first adhesive tape roller 83, which is pivotably and rotatably mounted on the bearing walls 78 and carries an adhesive element 84 over a circumferential area.

[0085] The first adhesive tape application device 82 further comprises a pivotable adhesive tape counter roller 85, which is associated with the first adhesive tape roller 83 and carries a counter element 86 over a circumferential area. The adhesive tape counter roller 85 is arranged above the first adhesive tape roller 83. It extends horizontally and runs perpendicular to the laminating web conveying direction 81 of the endless laminating web 40. The adhesive tape counter roller 85 extends over the entire width of the endless laminating web 40. It can be vertically displaced in a vertical guide 87 arranged on the bearing walls 78 by means of a lifting device 88 between an upper inactive position and a lower active adhesive position, in which it forms an adhesive tape application gap with the first adhesive tape roller 83.

[0086] With respect to the laminating web conveying direction 81, the coupling / uncoupling arrangement 76 has a laminating web separating device 89 downstream of the first adhesive tape application device 82. The laminating web separating device 89 comprises a laminating web separating element 90, which extends horizontally and runs perpendicular to the laminating web conveying direction 81 of the endless laminating web 40. The laminating web separating element 90 extends over the entire width of the endless laminating web 40 and is knife-shaped. It can be vertically displaced along a vertical guide 91 arranged on the bearing walls 78 by means of a lifting device 92 between an upper inactive position and a lower separating position.

[0087] The laminating track separating device 89 also includes a laminating track separating counter element 146, which is fixedly arranged on the bearing walls 78 and extends horizontally and runs perpendicular to the laminating track conveying direction 81 of the endless laminating track 40. The laminating track separating counter element 146 extends over the entire width of the endless laminating track 40 and supports the endless laminating track 40 from below when it is being separated. It is plate-like.

[0088] Downstream of the laminating web conveying direction 81, the coupling / uncoupling arrangement 76 has a laminating web-printing web merging device 93 downstream of the laminating web separating device 89, comprising a pair of merging rollers 94, 95. The merging rollers 94, 95 run parallel to each other and one above the other. They extend horizontally and perpendicular to the laminating web conveying direction 81 of the endless laminating web 40 and the printing web conveying direction 98 of the endless printing web 4, respectively. The merging rollers 94, 95 extend over the entire width of the endless laminating web 40 and the endless printing web 4, respectively. They are mounted in a vertical guide 96 arranged on the bearing walls 78, allowing them to be vertically displaceable and rotatable relative to each other. The merging roller 94 is assigned to the endless laminating web 40, while the merging roller 95 is assigned to the endless printing web 4.The merging roller 94 is arranged above the merging roller 95 and thus forms an upper merging roller 94, while the merging roller 95 forms a lower merging roller 95.

[0089] Below the laminating web guide roller 80, a printing web guide roller 97 is rotatably mounted on the bearing walls 78 in the first end region 79. The printing web guide roller 97 extends horizontally and perpendicular to the printing web conveying direction 98 of the endless printing web 4 in the coupling / uncoupling arrangement 76. It extends over the entire width of the endless printing web 4 and is associated with it.

[0090] With respect to the web conveying direction 98, a second adhesive tape application device 99 is located downstream of the web guide roller 97. The first adhesive tape roller 83 is also part of the second adhesive tape application device 99. The first adhesive tape roller 83 is used by both the first adhesive tape application device 82 and the second adhesive tape application device 99.

[0091] The second adhesive tape application device 99 has a pivotable or rotatable second adhesive tape roller 100, which carries an adhesive element 101 over a partial circumference. The second adhesive tape roller 100 extends horizontally and perpendicular to the conveying direction 98 of the endless print web 4. It extends over the entire width of the endless print web 4. The second adhesive tape roller 100 can be vertically displaced in a vertical guide 102 arranged on the bearing walls 78 by means of a lifting device 103 between a lower inactive position and an upper active adhesive position, in which it forms an adhesive tape application gap with the first adhesive tape roller 83.

[0092] Downstream of the printing web conveying direction 98 of the endless printing web 4, the coupling / uncoupling arrangement 76 comprises a perforating device 104 associated with the endless printing web 4. The perforating device 104 comprises an upper perforating roller 105 with a circumferentially arranged upper perforating arrangement 106. Furthermore, the perforating device 104 has a lower perforating roller 107 with a circumferentially arranged lower perforating arrangement 108. The perforating rollers 105 and 107 are arranged one above the other and are pivotable. They extend parallel to each other and horizontally. The perforating rollers 105 and 107 run perpendicular to the printing web conveying direction 98 of the endless printing web 4 and extend over the entire width of the endless printing web 4.The lower perforating roller 107 can be vertically displaced between a lower inactive position and an upper perforating position by means of a lifting device 109 along a vertical guide 110 arranged on the bearing walls 78.

[0093] A pair of deflection rollers 111, 112 are arranged between the laminating web separator element 146 and the upper perforating roller 105. The deflection rollers 111, 112 extend parallel to each other and horizontally. They are arranged adjacent to each other, one above the other. The upper deflection roller 111 is assigned to the endless laminating web 40 and forms a laminating web deflection roller. The lower deflection roller 112 is assigned to the endless printing web 4 and forms a printing web deflection roller. Each deflection roller 111, 112 is pivotably mounted on the bearing walls 78 and is connected to non-circular end plates 113 and 114, respectively.

[0094] A first laminating web-printing web deflection roller 115 is arranged between the laminating web separating counter element 146 and the laminating web-printing web merging device 93. This roller is connected to non-circular end plates 116. The first laminating web-printing web deflection roller 115 is pivotally mounted on the bearing walls 78 and extends horizontally. It runs perpendicular to the printing web conveying direction 98 of the endless printing web 4 or the laminating web conveying direction 81 of the endless laminating web 40.

[0095] With respect to the web conveying direction 98, a web separating device 117 is arranged downstream of the laminating web-web merging device 93. The web separating device 117 comprises a web separating element 118, which extends horizontally and runs perpendicular to the web conveying direction 98 of the endless web 4. It extends over the entire width of the endless web 4 and can be vertically displaced along a vertical guide 119 arranged on the bearing walls 78 by means of a lifting device 120 between a lower inactive position and an upper separating position. The web separating element 118 is knife-shaped.

[0096] The pressure web separating device 117 further comprises a pressure web separating counter element 121, which is fixedly arranged on the bearing walls 78 and extends horizontally. The pressure web separating counter element 121 runs perpendicular to the pressure web conveying direction 98 of the endless pressure web 4. It extends over the entire width of the endless pressure web 4 and is plate-like. When separating the endless pressure web 4, it supports the endless pressure web 4 from below.

[0097] A second laminating web-printing web deflection roller 122 is arranged between the printing web separator 121 and the laminating web-printing web feeder 93. This roller is connected to non-circular end plates 123. The second laminating web-printing web deflection roller 122 is pivotally mounted on the bearing walls 78 and extends horizontally. It runs perpendicular to the printing web conveying direction 98 of the endless printing web 4 or the laminating web conveying direction 81 of the endless laminating web 40.

[0098] The operation of the coupling / decoupling arrangement 76 is explained in more detail below.

[0099] In Fig. 5 The corrugated board production line 1 and the printing / laminating line production line 2 produce independently of each other. In the corrugated board production line 1, the continuous double-sided laminated corrugated board web is produced, while in the printing / laminating line production line 2, the continuous printing web 4, which can be printed using the inkjet printing device 58, and the continuous laminating web 40 are produced.

[0100] The endless laminating web 40 and the endless printing web 4 are conveyed separately from each other in the coupling / decoupling arrangement 76, in their respective, coherent conveying directions 81 and 98 respectively, one above the other. In the coupling / decoupling arrangement 76, they run horizontally and parallel, but spaced apart from each other.

[0101] The endless laminating web 40 runs below and contacts the laminating web guide roller 80 and the upper merging roller 94. The laminating web guide roller 80 and the upper merging roller 94 guide the endless laminating web 40. The adhesive tape counter roller 85 and the laminating web separator 90 are each in their upper inactive position. They are spaced apart from and positioned above the endless laminating web 40.

[0102] The endless laminating web 40 also runs above and spaced apart from the first adhesive tape roller 83, the upper perforating roller 105, the upper deflection roller 111, the laminating web separating counter element 146, the first laminating web printing web deflection roller 115 and the second laminating web printing web deflection roller 122.

[0103] The endless printing web 4 contacts the top of the printing web guide roller 97 and the lower merging roller 95. The printing web guide roller 97 and the lower merging roller 95 guide the endless printing web 4.

[0104] The endless printing web 4 runs spaced apart above the second adhesive tape roller 100, the lower perforating roller 107 and the printing web separating element 118, all of which are in their lower, inactive position.

[0105] The endless printing web 4 runs spaced below the first adhesive tape roller 83, the upper perforating roller 105, the lower deflection roller 112, the first laminating web printing web deflection roller 115 and the second laminating web printing web deflection roller 122.

[0106] The continuous printing web 4 is wound up in the printing web winding device 66. The continuous laminating web 40 is transferred to the corrugated board manufacturing device 1 via the laminating web transfer device 3 and glued to the single-sided laminated continuous corrugated board web 6 in the joining device.

[0107] The laminating web transfer arrangement 3 comprises a first deflection rod 124 and a second deflection rod 125. The first deflection rod 124 is located downstream of the coupling / uncoupling arrangement 76 in the printing / laminating web production arrangement 2 with respect to the conveying direction 81 of the endless laminating web 40. It extends horizontally and forms an angle of 45° with the conveying direction 81 of the endless laminating web 40. At the first deflection rod 124, the endless laminating web 40 is deflected by 90° and rotated by 180°. The endless laminating web 40 thus runs perpendicular to a longitudinal direction of the corrugated board production arrangement 1 in the laminating web transfer arrangement 3.

[0108] The second deflection rod 125 runs parallel to the first deflection rod 124. It is located within the corrugated board manufacturing assembly 1. The second deflection rod 125 deflects the endless laminating web 40 by 90° in the direction of the corrugated board conveying direction and turns it 180°. The endless laminating web 40 is conveyed downstream to the second deflection rod 125 in the conveying direction of the adjacent, single-sided laminated endless corrugated board web 6. The second deflection rod 125 is located between the material web splicing device 8 and the preheating assembly 37.

[0109] If the continuous printing web 4 is to be used as a laminating web in the corrugated board production unit 1, the continuous printing web 4 must be inserted into the corrugated board production unit 1, and the inkjet printing device 58 must be coupled to the corrugated board production unit 1. For this purpose, the first adhesive tape application device 82 is activated. The adhesive tape counter roller 85 is moved downwards towards the first adhesive tape roller 83. In doing so, it pulls the continuous laminating web 40 downwards with it, thereby lifting it away from the laminating web guide roller 80 and the upper collating roller 94.

[0110] When the adhesive tape counter roller 85 is moved downwards, it and the first adhesive tape roller 83 are pivoted or rotated such that the counter element 86 and the adhesive elements 84 face each other and come into contact with the endless laminating web 40 on opposite sides. A first adhesive tape 126, held by the adhesive element 84, is thereby attached to the endless laminating web 40 on the side facing the endless printing web 4, i.e., at the bottom, in its width direction. For this purpose, the first adhesive tape roller 83 is pivoted or rotated from the adhesive tape receiving position to the adhesive tape transfer position. It acts as an adhesive tape application roller. The adhesive tape counter roller 85 prevents the endless laminating web 40 from deflecting. The printing web splicing device 44 and the corrugated board production arrangement 1 continue production ( Fig. 6 ).

[0111] Then, as Fig. 7 The diagram shows that the adhesive tape counter roller 85 is moved back upwards to its inactive position. The first adhesive tape roller 83 is pivoted or rotated back to its inactive position. The merging rollers 94 and 95 are moved together evenly. They are moved together in such a way that the continuous laminating web 40 and the continuous printing web 4 touch each other at the first adhesive tape 126, thereby coupling or connecting them by means of the first adhesive tape 126.

[0112] Furthermore, the laminating track separating device 89 is put into operation. The laminating track separating element 90 is moved into its lower separating position. There it interacts with the laminating track separating counter element 92, separating the endless laminating track 40.

[0113] The endless laminating web 40 rests against the upper deflection roller 111, the first laminating web-printing web deflection roller 115, and the second laminating web-printing web deflection roller 122. The endless printing web 4 rests against the second deflection roller 112, the first laminating web-printing web deflection roller 115, and the second laminating web-printing web deflection roller 122.

[0114] Furthermore, the print web separating device 117 is put into operation. For this purpose, the print web separating element 118 is moved upwards into its upper separating position, whereby it separates the endless print web 4 with the aid of the print web separating counter element 121.

[0115] How Fig. 8 As shown, only the continuous printing web 4 is now conveyed through the coupling / uncoupling arrangement 76. In the printing web / laminating web production arrangement 2, only the continuous printing web 4 is produced. The continuous printing web 4 runs upwards from the first end section 79. It rests against the lower deflection roller 112 at the bottom, against the first laminating web-printing web deflection roller 115 at the bottom, and against the second laminating web-printing web deflection roller 122 at the top. The printed continuous printing web 4 is transferred to the corrugated board production arrangement 1 as a lamination web via the lamination web transfer arrangement 3. It is glued in the joining device of the single-sided laminated corrugated board web 6. The inkjet printing device 58 is coupled to the corrugated board production arrangement 1.

[0116] The decoupling of the inkjet printing device 58 from the corrugated board manufacturing arrangement 1 is then explained. How Fig. 9 As shown, the endless laminating web 40 is fed into the coupling / uncoupling arrangement 76 from the laminating web splicing device 70. It rests against the laminating web guide roller 80 and the upper merging roller 94 at the bottom. The first adhesive tape application device 82 and the laminating web cutting device 89 are inactive.

[0117] In the area of ​​the upper merging roller 94, a second adhesive strip 127 is arranged at the end of the endless laminating web 40 on the side facing the endless printing web 4, i.e., at the bottom, in its width direction. The endless laminating web 40 is then fixed in place at the upper merging roller 94. The upper merging roller 94 is, for example, designed as a vacuum roller. Alternatively, a clamping bar is assigned to it, for example.

[0118] From the web winding device 66, the winding web 129, which corresponds to the printing web 4 and may be printed, is inserted into the coupling / uncoupling arrangement 76. Its end is placed on top of the lower merging roller 95. The winding web 129 is then fixed in place at the lower merging roller 95. The lower merging roller 95 is, for example, designed as a vacuum roller. Alternatively, a clamping bar may be assigned to it.

[0119] The second adhesive tape application device 99 and the perforating device 104 are activated. The second adhesive tape roller 100 is moved upwards and pivoted or rotated from its adhesive tape receiving position to its adhesive tape transfer position. The first adhesive tape roller 83 is also pivoted or rotated. Using the second adhesive tape roller 100, a third adhesive tape 128 is applied from below to the continuous printing web 4, extending in its width direction. It acts as an adhesive tape application roller. The first adhesive tape roller 83 now acts as a counter-roller for the adhesive tape, preventing the continuous printing web 4 from deflecting. The corrugated board production arrangement 1 and the inkjet printing device 58 operate in coupled mode.

[0120] The lower perforating roller 107 is moved upwards and brought into its perforating position. The upper perforating roller 105 is pivoted or rotated into its perforating position. The perforating rollers 105 and 107 work together in their perforating positions and perforate the continuous printing web 4 across its entire width. The perforating assemblies 106 and 108 are facing each other.

[0121] The endless printing web 4 lies at the bottom of the second deflection roller 112 and at the bottom of the first laminating web-printing web deflection roller 115, as well as at the top of the second laminating web-printing web deflection roller 122.

[0122] Then, as Fig. 10 The figure shows that the laminating web-printing web merging device 93 is actuated. The merging rollers 94, 95 are moved together evenly. The continuous laminating web 40 is bonded to the continuous printing web 4 there by means of the second adhesive strip 127.

[0123] The endless laminating web 40 lies at the top of the upper deflection roller 111, the first laminating web-printing web deflection roller 115 and the second laminating web-printing web deflection roller 122.

[0124] The endless printing web 4 lies at the bottom of the lower deflection roller 112, the first laminating web printing web deflection roller 115 and the second laminating web printing web deflection roller 122.

[0125] Subsequently, the winding web 129 coming from the printing web winding device 66 is adhesively connected to the endless printing web 4 by means of the third adhesive strip 128 ( Fig. 11 ).

[0126] How Fig.12 As shown, the original endless printing web 4 tears downstream towards the laminating web-printing web merging device 93 at the perforation created by the perforating device 104. The merging rollers 94, 95 are then moved apart again ( Fig. 13 The corrugated board production line 1 and the inkjet printing device 58 are decoupled. The continuous laminating web 40 is used again in the corrugated board production line 1.

[0127] The following refers to the Fig. 16 bis 28 A second embodiment of the coupling / decoupling arrangement is described. No other differences exist. Identical parts are given the same reference numerals as in the previous embodiment, to whose description reference is made. Structurally different, but functionally similar, parts are given the same reference numerals with a suffix "a".

[0128] In the coupling / decoupling arrangement 76a, compared to the first embodiment, the printing web guide roller 97 can be moved vertically along a vertical guide 147, which is arranged on the bearing walls 78.

[0129] Furthermore, the coupling / uncoupling arrangement 76a has an upper deflection roller 130, which is rotatably mounted on the bearing walls 78. A lower deflection roller 131 is arranged below the upper deflection roller 130. The lower deflection roller 131 can be displaced along a vertical guide 132 arranged on the bearing walls 78 by means of a lifting device 133 between a lower guide position and an upper contact position.

[0130] A web separating device 134 is arranged between the pair of laminating web guide rollers 80 and printing web guide rollers 97 and the pair of upper deflection rollers 130 and lower deflection rollers 131. The web separating device 134 comprises a web separating element 135, which can be vertically displaced along a vertical guide 136 arranged on the bearing walls 78 by means of a lifting device 137. The web separating device 134 further comprises a web separating counter element 138, which is block- or plate-like and associated with the web separating element 135.

[0131] The pressure-track separating counter element 138 is arranged on a removable first slide 139. The first slide 139 is displaceable along a first rail 140, which runs horizontally and is arranged on the bearing walls 78. The first slide 139 is completely removable from the frame 77.

[0132] The first slide 139 also carries a pair of deflection rollers 111, 112, which, in comparison with the first embodiment, are arranged side by side with the pressure web separating counter element 138 interposed.

[0133] In contrast to the first embodiment, the laminating track separating device 89a has the laminating track separating counter element 146 on a second carriage 141, which is displaceable along a horizontal second rail 142. The second rail 142 is arranged on the bearing walls 78. The second carriage 141 is completely removable from the frame 77.

[0134] The second carriage 141 also carries the first laminating web printing web deflection roller 115 and the adhesive tape roller 83, which is assigned to the vertically displaceable adhesive tape counter roller 100.

[0135] According to Fig. 18 The corrugated board production line 1 and the printing / laminating web production line 2 operate independently of each other. In the corrugated board production line 1, the double-sided laminated corrugated board web is produced, while in the printing / laminating web production line 2, the continuous printing web 4 and the continuous laminating web 40 are produced. The carriages 139 and 141 are inserted into the frame 77.

[0136] The endless laminating web 40 enters the coupling / uncoupling arrangement 76a from above, starting at the laminating web splicing device 70. It is deflected by 90° by the upper deflecting roller 130 and runs horizontally downstream of it. The endless laminating web 40 rests against the bottom of the upper merging roller 94.

[0137] The laminating track separating device 89a is in its inactive position.

[0138] The continuous printing web 4 runs horizontally in the coupling / uncoupling arrangement 76a. It contacts the printing web guide roller 97, the lower deflecting roller 131, and the lower merging roller 95. The printing web guide roller 97 is in its lower inactive position. The lower deflecting roller 131 is in its lower guide position. The lower merging roller 95 is in its lower inactive position. The adhesive tape counter roller 100 and the printing web separating device 117 are inactive.

[0139] How Fig. 19 As shown, for coupling the inkjet printing device 58 with the corrugated board manufacturing arrangement 1, a first adhesive strip 143 is arranged on top of the continuous printing web 4 by means of the adhesive strip application device 99a. This strip extends over the entire width of the continuous printing web 4. For this purpose, the adhesive strip roller 83 and the adhesive strip roller 100 are pivoted or rotated. The adhesive strip roller 83 acts as the adhesive strip application roller. The first adhesive strip 143, held by the adhesive strip roller 83, is positioned on top of the continuous printing web 4 in the adhesive strip transfer position. The adhesive strip roller 100 is in its upper active position and acts as the adhesive strip counter roller.

[0140] How Fig. 20 As illustrated, the upper and lower merging rollers 94, 95 then move together, thereby merging the continuous printing web 4 and the continuous laminating web 40 in the area of ​​the first adhesive strip 143 and bonding them together. The continuous laminating web 40 is then applied to the adhesive strip roller 83 and the first laminating web-printing web deflection roller 115, as well as the second laminating web-printing web deflection roller 122. The continuous printing web 4 is applied to the adhesive strip roller 83 and the first laminating web-printing web deflection roller 115, as well as the second laminating web-printing web deflection roller 122.

[0141] The laminating track separating device 89a is actuated. The laminating track separating element 90 is moved downwards into its separating position and separates the endless laminating track 40 with the aid of the laminating track separating counter element 146.

[0142] The print web separating device 117 is actuated. The print web separating element 118 is moved upwards into its separating position and separates the endless print web 4 with the aid of the print web separating counter element 121.

[0143] The corrugated board production line 1 and the printing / laminating web production line 2 operate in a coupled state. A continuous printing web 4 is produced and transferred to the corrugated board production line 1 as a laminating web. This is in Fig. 21 illustrated.

[0144] Decoupling the inkjet printing device 58 and the corrugated board manufacturing arrangement 1 requires a changeover of the coupling / decoupling arrangement 76a. For this purpose, the upper merging roller 94 is moved downwards, so that the continuous printing web 4 is lifted from the adhesive tape roller 83 and the first laminating web-printing web deflection roller 115. The continuous printing web 4 is held under tension ( Fig. 22 ).

[0145] Subsequently, the carriages 139 and 141 are moved laterally out of the frame 77. Then, the printing web guide roller 97 and the lower deflection roller 131 are moved upwards ( Fig. 23 ).

[0146] The first carriage 139 is then reinserted under the continuous printing web 4. The continuous printing web 4 rests against the deflection rollers 111 and 112 at the top. The printing web guide roller 97 and the lower deflection roller 131 are then moved back down ( Fig. 24 ).

[0147] How Fig. 25 As shown, the upper merging roller 94 is then moved upwards again, lifting itself away from the endless printing web 4.

[0148] Below the endless lamination track 40, the second sled 141 is pushed back in.

[0149] The former endless printing web 4 or winding web 129 is fed into the coupling / uncoupling arrangement 76a by the printing web winding device 66. It rests against the upper surface of the lower merging roller 95, the lower deflecting roller 131, and the printing web guide roller 97. The endless printing web 4 is located below the second carriage 141. One end of the printing web 4 or winding web 129 rests against the upper surface of the printing web guide roller 97. It is advantageous if the printing web 4 or winding web 129 is fixed at this point relative to the printing web guide roller 97. For example, the printing web guide roller 97 is designed as a vacuum roller, which is then active. For example, the printing web guide roller 97 is assigned at least one clamping element, such as a clamping bar.

[0150] At the end of the endless printing web 4, a second adhesive strip 144 is arranged at the top in the area of ​​the printing web guide roller 97, extending over the entire width of the endless printing web 4.

[0151] The continuous laminating web of the corrugated board manufacturing arrangement 1 is fed into the coupling / uncoupling arrangement 76a from above. In the area of ​​the upper deflection roller 130, a third adhesive strip 145 is arranged at the bottom of the continuous laminating web of the corrugated board manufacturing arrangement 1, extending over the entire width of the continuous laminating web 40. The continuous laminating web of the corrugated board manufacturing arrangement 1 is fixed at the upper deflection roller 130. One end of the continuous laminating web of the corrugated board manufacturing arrangement 1 is located at the bottom of the upper deflection roller 130. For example, the upper deflection roller 130 is designed as a vacuum roller, which is then active. Alternatively, at least one clamping device, such as a clamping bar, is assigned to the upper deflection roller 130.

[0152] How Fig. 26As shown, the printing web guide roller 97 and the lower deflection roller 131 are then moved upwards.
