Abstract

A corrugated cardboard plant comprises at least one device for producing a respective corrugated cardboard web laminated on one side; a lamination web dispensing device; a lamination web printing device disposed downstream of the lamination web dispensing device; and a device, disposed downstream of the lamination web printing assembly, for producing a corrugated cardboard web laminated on two sides from the at least one corrugated cardboard web laminated on one side and from a lamination web. The at least one device for producing a respective corrugated cardboard web laminated on one side is configured and/or disposed in such a manner that the at least one corrugated cardboard web laminated on one side, at least in a manner adjacent upstream of the device for producing a corrugated cardboard web laminated on both sides, has a respective upwardly directed corrugation. The lamination web in the device for producing a corrugated cardboard web laminated on two sides is guided in such a manner that said lamination web therein runs above the at least one corrugated cardboard web laminated on one side.

Dependent claims

A corrugated cardboard plant for producing corrugated cardboard, comprising:

a device for producing a corrugated cardboard web laminated on one side from a cover web and a material web;
a lamination web dispensing device for dispensing a lamination web;
a lamination web printing assembly, disposed downstream of the lamination web dispensing device, comprising a lamination web printing device for imprinting the lamination web;
a device, disposed downstream of the lamination web printing assembly, for producing a corrugated cardboard web laminated on two sides from the corrugated cardboard web laminated on one side and the lamination web;
and
a gluing unit which is disposed upstream of the device for producing a corrugated cardboard web laminated on two sides and is configured such that said gluing unit applies glue to the corrugated cardboard web laminated on one side from above the corrugated cardboard web laminated on
one side, wherein:
the device for producing a corrugated cardboard web laminated on one side is configured such that the corrugated cardboard web laminated on one side, at a location adjacent to and upstream of the device for producing a corrugated cardboard web laminated on both sides, has an upwardly directed corrugation;
the device for producing a corrugated, cardboard web laminated on one side comprises a corrugating installation for providing a corrugated material web;
the device for producing a corrugated cardboard web laminated on one side further comprises a glue application installation for applying glue to the corrugated material web to provide a glued corrugated material web, wherein the glue application installation is disposed on a side of the corrugating installation that faces the device for producing a corrugated cardboard web laminated on two sides;
the device for producing a corrugated cardboard web laminated on one side comprises a pressure installation for pressing the cover web against the glued corrugated material web, the pressure installation having a contact pressure entry;
the contact pressure entry is disposed so as to be adjacent to the glue application installation;
the corrugated cardboard web laminated on one side exits the pressure installation by way of a contact pressure exit which faces away from the device for producing a corrugated cardboard web laminated on two sides;
the lamination web is guided into the device for producing a corrugated cardboard web laminated on two sides such that said lamination web therein runs above the corrugated cardboard web laminated on one side;
and
the contact pressure entry, of the pressure installation, faces the device for producing a corrugated cardboard web laminated on two sides.
