Embodiment Construction
[0053] figure 1 It is shown that the facility according to the invention is used to treat a basis weight of 24 g / m 2 up to 32g / m 2 The cigarette paper web 2 of the present invention, said installation is generally indicated with the reference number 1. The paper processing facility 1 mainly includes the following necessary main stations: an unreeling station 3, a gravure printing unit 5, a hot air dryer 7, a humidifier 9, a contact dryer 11, and a rewinding station ( reeling up station) 13.
[0054] The unwinding station 3 comprises a sleeve (not shown in detail) with an inner diameter of about 76 mm, from which the paper web 2 is reeled off. Cuff inner diameters of different sizes may also be used, for example 120mm. The sleeves are rotatably mounted or attachable to respective rotating shafts. Alternatively, the paper roll can be wound onto a steel core suspended in the unwinding device of the unwinding station. In order to eliminate stress or variability of the paper ...

Abstract
The invention relates to an arrangement for processing a paper web having a low surface area density not exceeding 70g / m2, in particular a cigarette paper web, comprising: an input side, over which the paper web is fed into the arrangement; an output side, over which the paper web leaves the arrangement, wherein the paper web passes the arrangement from input side to output side in a direction of conveyance; a device (5) downstream of the input side, in particular a printing unit, preferably a gravure printing unit, for applying a liquid printing medium to the paper web; a first drying station (7) following the applying station in direction of conveyance, in particular hot-air drying, for drying the printing medium applied to the paper web; a device (9) following the first drying in direction of conveyance for moistening the paper web and a second drying station (11) following the moistening device in direction of conveyance, by which the moistened paper web is dried.
Description
technical field [0001] The present invention relates to the treatment of quantitative not exceeding 70 or 60g / m 2 , especially not more than 50g / m 2 Paper webs, especially cigarette paper webs, and corresponding methods. For example, a basis weight of 20 to 40 g / m can be considered 2 cigarette paper banner. Commonly, cigarette papers include fillers, especially calcium carbonate fillers, to ensure sufficient opacity of the cigarette paper. Background technique [0002] In the cigarette industry, the surface of cigarette paper needs to be modified for smoldering and ignition safety. In so-called low ignitability (LIP) cigarette papers, a distinctly delimited zone will be realized on the cigarette paper where the air permeability is reduced to such an extent that once the cigarette is placed on a hard surface and the cone ( glowing cone) has reached the area, it will go out. This type of smoldering protection is achieved, for example, by applying a starch solution or sus...
