DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/AT91/00094 filed Aug. 14, 1991 and based, in turn, upon Austrian National Application A1702/90 filed Aug. 6, 1990.
FIELD OF THE INVENTION
This invention relates to a process and a device for applying impressing or removing aqueous substances, or free flowing substances on a web like material, particularly textile material by means of a roller pressed against this surface or web.
BACKGROUND OF THE INVENTION
In simple cases, a liquid or flowable substance to be controlled on, a web can be water, e.g. when a web of material, a flat formation, a roller or the like is to be humidified or dehumidified. The liquid can also contain various chemicals, for example dyes, impregnating substances and/or solid substances. It can also be a foam.
It is known to apply substances by means of magnetically pressed rollers It is also known to use rollers pressed by magnetic force, which are either dipped into a liquid or are supplied by a feeding roller. In both cases, on the surface of the application roller a thin film of liquid is created, which is then transferred by the application roller at the contact point. In the wedge formed in front of the contact point an accumulation of liquid can result.
In application roller with a smaller diameter applies less substance and the amount of applied substance increases with the diameter of the roller. A weaker or stronger pressing force applied to the rollers results, for instance, in a textile surface with different depth effects, but the amount of applied substance is basically determined by the diameter of the application roller.
The surface structure of an application roller also influences the amount of applied substance. As a rule, application rollers with structured, rough or engraved surfaces, or with wire wrappings apply more substance than rollers with smooth surfaces. The nature of the substance to be applied, its adhesion to the roller and the absorption capability of the substrate also have influence on this type of amount determination.
OBJECTS OF THE INVENTION
Still another object is to provide an apparatus for implementing the process according to the invention.
Yet another object of this invention is to carry out the process according to the Invention with the highest possible degree of uniformity, by taking into consideration the depth action desired in each case and at the same time insuring a gentle treatment of the material.
SUMMARY OF THE INVENTION
The process of the invention offers great variety in its application possibilities and achieving a precise setting, implicitly and a precise reproducibility of all technologically important parameters. There is independence from the tension of the web and it is possible to achieve electrically actuated, precise, electrically controllable setting, and if desired even automatic setting of the pressure force and pressure uniformity over a working width as large as desired. Easy handling, reliable operational safety and a high degree of economic efficiency as a result of relatively low manufacturing and operating costs are to be mentioned as specific advantages.
A cylinder, or roller, which is attracted or pressed by preferably magnetic force applied directly or indirectly to this roller achieves a strong capability of influencing the application output, or conversely the stripping output, or the substance absorption capability.
The device of the invention is characterized in that the working roller has over its entire working width a surface capable to absorb, store, transport liquid and to deliver it under pressure and that either the working roller or the counter surface is covered over the entire working width by an absorbent and/or compressible jacket and that in the presence of a liquid or flowable substance on or in the roller jacket (8) or on the surface, or in the web of material, the liquid applying or liquid removing transfer process with substance amount control is a result of the fact that the jacket covering th
