Abstract

A method and machine arrangement for sequential processing of sheet-like substrates are disclosed. At least one of a front side and a rear side of the substrates is processed in a production line one after another. A printing ink or another type of ink is applied in at least one non-impact printing device on the respective side of the substrates. The printing ink or the other type of ink is dried. A dispersion coating or a coating cured by UV radiation is then applied onto the respective side of the substrates. The dispersion coating or the coating cured by UV radiation is dried and the substrates are fed to a mechanical processing device for carrying out a further mechanical processing of the substrates. The further mechanical processing is performed by at least one of punching, inserting grooves, separating parts and by breaking out panels from their respective composite in the respective substrate.

First claim

The invention claimed is:

1. A method for the sequential processing of sheet-type substrates, in which a front side and/or a back side of each of these substrates is or are processed in succession in a production line, wherein in at least one non-impact printing unit ( 06 ) in each case, a printing ink or ink is applied to the respective side of the substrate in question, wherein the printing ink or ink is dried, after which a dispersion varnish or a varnish that is cured by UV radiation is applied to the side of the substrates in question, wherein the dispersion varnish or the varnish that is cured by UV radiation is dried, wherein each of the substrates is imprinted by means of a plurality of non-impact printing units ( 06 ), wherein these non-impact printing units ( 06 ) imprint the substrates in succession in the transport direction (T), wherein the plurality of non-impact printing units ( 06 ) imprint the substrates with multiple inks, wherein for each of these printing inks, a specific one of said non-impact printing units ( 06 ) is provided, characterized in that before the printing ink or ink is applied to the side of the substrates in question, a undercoat or initial coat is first applied in each case, wherein the substrates that have been treated with an application of the undercoat or initial coat are dried by means of hot air and an irradiation with infrared radiation, wherein the substrates that have been treated with an application of printing ink or ink are dried by means of irradiation with ultraviolet radiation or by means of hot air and an irradiation with infrared radiation, wherein the substrates are fed to a mechanical further processing unit ( 11 ) that performs a mechanical further processing of the substrates, wherein the mechanical further processing involves stamping and/or creasing and/or separating parts of the respective substrate, and/or punching copies out of their respective attachment in the respective substrate.

2. The method according to claim 1 , characterized in that the undercoat or initial coat is dried in each case before the printing ink or ink is applied to the side of the substrates in question.

3. The method according to claim 1 , characterized in that the undercoat or initial coat and/or the varnish is applied to the side of the substrates in question, in each case over the entire surface or a portion of the surface thereof, or at points that are specified in advance.

4. The method according to claim 1 , characterized in that the undercoat or initial coat is applied to the side of the substrates in question, in each case in a primer application unit ( 02 ) or in a cold foil application unit ( 03 ).

5. The method according to claim 1 , characterized in that a further application of printing ink or ink is carried out in at least one offset printing unit ( 04 ) or flexographic printing unit ( 04 ) or in a printing unit ( 04 ) for printing in a screen printing process.

6. The method according to claim 1 , characterized in that at least one of the non-impact printing units ( 06 ) imprints each of the substrates at least nearly over its entire width oriented transversely to the transport direction (T).

7. The method according to claim 1 , characterized in that each of the substrates is imprinted with multiple inks as it passes through at least one of the non-impact printing units ( 06 ) or the offset printing unit ( 04 ) or the flexographic printing unit ( 04 ) or the printing unit ( 04 ) that prints in a screen printing process.

8. The method according to claim 1 , characterized in that the substrates that have been treated by an application of the dispersion varnish are dried by means of hot air and/or by means of an irradiation with infrared radiation, and/or in that the substrates that have been treated by an application of varnish that is cured with UV radiation are dried by means of an irradiation with ultraviolet radiation.

9. The method according to claim 1 , characterized in that substrates made of a paper or of a single ply or multi-ply paperboard or a cardboard are processed.

10. The method according to claim 1 , characterized in that the substrates are processed in each case to produce packaging materials.

11. A press assembly having a plurality of processing stations for processing sheets, wherein a plurality of processing stations ( 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 ) are arranged in succession in the transport direction (T) of the sheets for the inline processing of these sheets, wherein at least one of these processing stations ( 06 ) is embodied as a non-impact printing unit ( 06 ) and at least one processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) located downstream of the non-impact printing unit ( 06 ) in the transport direction (T) of the sheets is embodied as a dryer ( 07 ; 09 ), wherein at least one additional processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) located downstream of the non-impact printing unit ( 06 ) in the transport direction (T) of the sheets is embodied as a coating unit ( 02 ; 03 ; 08 ), wherein the downstream coating unit ( 02 ; 03 ; 08 ) in question is embodied as a coating unit for applying a coating in the form of a varnish to the respective sheet, wherein a plurality of non-impact printing units ( 06 ), each controlled individually, are arranged along the transport path of the sheets, wherein each of the plurality of non-impact printing units ( 06 ) is embodied as an inkjet printer, characterized in that at least one processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) located upstream of the non-impact printing unit ( 06 ) in the transport direction (T) of the sheets is embodied as a coating unit ( 02 ; 03 ; 08 ), wherein the upstream coating unit ( 02 ; 03 ; 08 ) in question is embodied as a coating unit for applying a coating in the form of a primer or a cold foil to the respective sheet, wherein a dryer ( 07 ; 09 ) is located downstream in each case of the at least one processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) located upstream of the non-impact printing unit ( 06 ) in the transport direction (T) of the sheets, which is embodied as a coating unit ( 02 ; 03 ; 08 ) for applying a primer or a cold foil, and the at least one processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) located downstream of the non-impact printing unit ( 06 ) in the transport direction (T) of the sheets, which is embodied as a coating unit ( 02 ; 03 ; 08 ) for applying a varnish, wherein the dryer ( 07 ; 09 ) in question, which is located downstream of the processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) that is embodied as a coating unit ( 02 ; 03 ; 08 ) for applying a primer or a cold foil, is embodied as a dryer ( 07 ; 09 ) for drying the sheet in question by means of an irradiation with infrared radiation and by means of hot air, wherein the dryer ( 07 ; 09 ) in question, which is located downstream of the processing station ( 01 ; 02 ; 03 ; 04 ; 07 ; 08 ; 09 ; 11 ; 12 ) that is embodied as a coating unit ( 02 ; 03 ; 08 ) for applying a varnish, is embodied as a dryer for drying the sheets in question by means of an irradiation with infrared radiation or by means of hot air or as a dryer for drying the sheets in question by means of an irradiation with ultraviolet radiation.
