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.

The invention discloses circulating feeding printer combining screen printing and digital ink jetting, comprising: a rack, the rack includes an upper rack layer and a lower rack layer, the two layers are respectively provided with a transmission platen capable of moving relative to the rack, each transmission platen is provided with a movable printing platen bearing a print medium capable of sliding relative to the transmission platen, a locking device locking the movable printing platen and the transmission platen is arranged between them, platen transfer devices capable of transferring the movable printing platen onto the transmission platen at the different layer are disposed on the rack, separately located at two sides of the transmission platens, the rack is further provided with a screen printer and an inkjet printer used for printing separately. The present invention prints high quality products, occupies small area, has high production efficiency and automation grade.

A paste supply apparatus includes: a pot holder which holds a paste pot including an inner lid movable in a container; an ejecting member; an annular protruding portion protruding downward from a lower surface of the ejecting member; a suction power generating mechanism which generates suction power in an internal space surrounded by the annular protruding portion; and an ejecting member lifting unit which moves up and down the ejecting member, The ejecting member lifting unit causes the ejecting member to press down the inner lid of the paste pot held by the pot holder to eject the paste from the through hole, and thereafter lifts the ejecting member which holds the inner lid by the suction power generated within the internal space of the annular protruding portion by the suction power generating mechanism.

A paste dispensing transfer system of a stencil printer is configured to print an assembly material on an electronic substrate. The transfer system includes a paste cartridge mechanism coupled to a print head assembly of the stencil printer, and a rotary indexing mechanism coupled to a frame of the stencil printer. The paste dispensing transfer system is configured to transfer a used paste cartridge from the print head assembly to the rotary indexing mechanism supported by the frame and to transfer a new paste cartridge from the rotary indexing mechanism to the print head assembly.

Screen printing device for applying an ink, having at least: a) a conveyor belt, b) a rotating hollow cylindrical screen stencil arranged above the conveyor belt with a circumferential screen and a rotating ink removal cylinder arranged adjacent the screen stencil, wherein: c) inside the screen stencil an ink supply device, a first doctor blade adjacent the conveyor belt, a second doctor blade adjacent the ink removal cylinder, and a third doctor blade, which is arranged upstream of the first doctor blade in the running direction of the conveyor belt and/or the rotational direction of the screen stencil are provided.

A sheet generator circuit is described. The sheet generator includes electronic circuitry to receive a line group of image data including multiple rows of data from a frame of image data. The multiple rows are sufficient in number to encompass multiple neighboring overlapping stencils. The electronic circuitry is to parse the line group into a smaller sized sheet. The electronic circuitry is to load the sheet into a data computation unit having a two dimensional shift array structure coupled to an array of processors.
