Abstract

A web of material serves for use in a corrugating machine for the manufacture of sheets of corrugated board. The corrugating machine comprises at least two unroll stands for unwinding webs of material. A fluting unit serves for the manufacture of at least one corrugated medium from one of the webs of material. A processing equipment serves for uniting the webs of material to form a web of corrugated board. The sheets of corrugated board are cut from the web of corrugated board by means of a cutting unit. A printing system is provided for printing at least one of the webs. The web of material has a coating for improved printing quality. A method for the manufacture of sheets of corrugated board is specified, using such a web of material. The results are sheets of corrugated board with improved imprint.

Claims

1. A method for the manufacture of sheets of corrugated board (62, 67) on a corrugating machine, comprising

at least two unroll stands (2, 9, 21) for unwinding webs of material (3, 8, 22) from reels of material;

at least one fluting unit (10) for the manufacture of at least one corrugated medium (8) from one of the webs of material;

at least one processing equipment (1, 36, 37) for uniting the corrugated medium (8) and at least another web of material (3, 22) to form a web of corrugated board (41);

a cutting station (48, 54) for cutting the sheets of corrugated board (62, 67) from the web of corrugated board (41);

a printing system (27;

69) for printing at least one of the webs (3;

41);

comprising the following steps;

applying a coating (3b) for improved printing quality on at least one web (3) which is to be printed;

printing the web (3) which is to be printed.

2. A method according to claim 1, wherein the print is sealed after printing.

3. A method according to claim 1, wherein the web (3;

41) which is to be printed is printed digitally.

4. A method according to claim 1, wherein the environment of the web (3;

41) which is to be printed is air-conditioned during printing.

5. A method according to claim 1, wherein a temperature is kept during printing, which is lower than 40°

C.

6. A method according to claim 1, wherein the at least one web (3) which is to be printed is cleaned prior to printing.
