Abstract An improved device for applying a liquid agent such as dye in the form of a thin film to and more uniformly across the whole breadth of a flat sheet material, such as textile fabrics, which material is moved relatively past and separated from the applying device. The novel applying device includes a rotary screen cylinder positioned above the sheet material and having an internally disposed pressure or stow squeegee acting on the inner wall thereof in cooperation with an externally disposed doctor or counterpressure squeegee engaging the outer surface thereof and preferably with the squeegees arranged perpendicularly below the axis of the rotary screen. The opposed squeegees may be cylindrical or generally flat or combinations of both and preferably are magnetically attracted to one another through the rotary screen. Another form utilizes a further cylindrical roller disposed parallel to a cylindrical external doctor squeegee and placed below the surface of the sheet material to which the liquid agent is applied. In this latter form, both of said rollers rotatively work together in a common rotative direction, with said doctor squeegee rolling in a counterdirection to a depending flow of the liquid agent issuing from the rotary screen adjacent to the external doctor roller.
A device for applying a liquid agent onto a flat material, especially to a textile fabric, said liquid agent being applied to the surface of said material in the form of a film by means of an applying device, said material being moved relatively to said applying device, said applying device consisting of a rotatable screen cylinder arranged at a distance above the material to be treated, at least one pressure and stow squeegee acting on the inwall of said screen cylinder, at least one counterpressure or doctor squeegee being opposed to said pressure and stow squeegee at the outside of said screen cylinder.
