SCREEN-PRINTING CYLINDER
20230001685 · 2023-01-05 ·

A screen-printing cylinder includes a cylinder shell and one or more flexible surface elements on the cylinder shell. The one or more flexible surface elements are at least one of resilient or springy, and the one or more flexible surface elements are elliptical patches or circular patches. The flexible surface elements give way upon contact with sheet grippers projecting from an impression cylinder, so that it is not necessary to move the screen-printing cylinder out to avoid contact with the sheet grippers.

Device for generating a pattern on a clothing for a machine for manufacturing a web material

A device for producing a pattern combination on a clothing includes the following: a rotary screen, a cylindrical jacket surface with a perforation pattern that defines a first pattern component. Material in the liquid or pasty state is pressed through the perforations of the jacket surface of the rotary screen and deposited on the surface of the clothing in order to produce the first pattern component on a surface of the clothing, while the rotary screen, rotating several times about a longitudinal axis thereof, rolls on the surface of the clothing in at least one path that continuously revolves on the surface of the clothing at least once. At least one device produces, synchronously and/or simultaneously, a second pattern component, which device is connected indirectly or directly to the rotary screen. The device for producing the pattern combination also includes a post-run system.

SCREEN PRINTING APPARATUS AND METHODS

Disclosed herein are apparatuses for screen printing on a surface of a three-dimensional substrate comprising a substantially rigid, substantially planar frame having a perimeter defining a region within the perimeter having a given surface area; and a screen attached to the frame and extending across at least a portion of the surface area, wherein the screen comprises a first portion through which a liquid printing medium can pass onto a proximate three-dimensional substrate; and a second portion coated with an emulsion substantially preventing the liquid printing medium from passing through the second portion of the screen, wherein the screen has a fixed tension of less than about 20 N/cm. Methods and systems for screen printing on a surface of a three-dimensional substrate are also disclosed herein.
