Embodiment Construction

[0041] figure 1 is a side view, partially in section, schematically illustrating a converting machine or line 1 comprising an exemplary embodiment of an inkjet printing device 2 for printing on absorbent sheet products 3 .

[0042] The converting machine or converting line 1 comprises a supply roller 5 , an inkjet printing device 2 , a plurality of delivery rollers 6 , 7 and finally a converting unit 8 . A continuous absorbent substrate web 51 is led from supply roll 5 to print zone 10 by a first series of transport rolls 6 . Then, the absorbent substrate web 51 is printed by the inkjet printing device 2 . The resulting printed absorbent substrate 52 is then led from the printing zone 10 to the final converting unit 8 by means of a second series of transport rollers 7 .

[0043] In this embodiment, the supply roll 5 provides an absorbent substrate web 51 comprising one layer. However, it is also possible to provide an absorbent substrate web comprising two, three or more laye...

Abstract

An inkjet printing apparatus for printing an image on an absorbent substrate (51, 52), the inkjet printing apparatus (2) comprising a print head unit (20) and a dust removal device (4), the absorbent substrate comprising a print side (53) and an opposite side (54), the absorbent substrate being conveyed between the print-head unit (20) and the dust removal device (4), the print head unit (20) defining a print zone (10) on the print side (53), wherein the dust removal device (4) comprises a pumping chamber (40) formed of a pre-pumping sub-chamber (41), a print zone sub-chamber (42) and a post-pumping sub-chamber (43), said chambers being positioned at the opposite side (54), wherein the pre-pumping sub-chamber (41) is positioned substantially upstream from the print zone (10), the print zone sub-chamber (42) is positioned substantially at the print zone (10), the post-pumping sub-chamber (43) is positioned downstream from the print zone (10), and wherein a second pressure (P2) in the print zone sub-chamber (42) is higher than a first pressure (P1) in the pre-pumping sub-chamber (41) and a third pressure (P3) in the post-pumping sub-chamber (43) so as to create a suction impact to dust particles generated by the conveyed absorbent substrate.

Description

technical field [0001] One aspect of the present invention relates to an inkjet printing device for an absorbent substrate which may be formed from a tissue web (obtained by conventional wet pressing or through air drying manufacturing methods or other manufacturing methods) Or non-woven fabrics (obtained by air-laid manufacturing methods or anti-wire-laid manufacturing methods or other manufacturing methods). Such absorbent substrates can be converted into absorbent sheet products having specific (but not exclusive) hygiene or household uses. As an example, such absorbent sheet products may be used in restaurants as napkins. Other uses like towels, bathroom tissue, etc. are also possible. Background technique [0002] Tissue paper refers to an absorbent paper based on cellulose fibres, also known in this technical field as tissue-based sheet. Typical absorbent papers have a low basis weight in the range of 10-60 g / m2, preferably 30-50 g / m2. [0003] Nonwovens comprising...
