Screen printer having mask pressing device for determining tension of mask by calculating mask deflection amount
A screen printer that measures a tension of a mask in a machine, including a mask holding device configured to hold a mask; a board device configured to position a board from below with respect to the mask held by the mask holding device; a squeegee device configured to apply and spread a cream solder on an upper surface of the mask; a mask pressing device configured to press the mask at a set pressure by a pusher which is installed on an upper travelling device or a lower travelling device with respect to the mask; a mask measurement device, installed on the upper travelling device or the lower travelling device to be opposed to the pusher, which is configured to measure a height of the mask; and a tension measurement device configured to calculate a tension of the mask based on a measured value of the mask measurement device.
Paste dispensing transfer system and method for a stencil printer
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.

COMPONENT LOADING VERIFICATION SYSTEM AND METHOD
A stencil printer for printing an assembly material on an electronic substrate includes a frame, a stencil coupled to the frame, the stencil having apertures formed therein, a support assembly coupled to the frame, the support assembly being configured to support the electronic substrate, a print head gantry coupled to the frame, and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The stencil printer further comprises a verification system to determine whether an item placed within the stencil printer is properly installed within the stencil printer.
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.

DEPOSIT LEVELLING
A method for producing a flat feature on a substrate, comprises the steps of printing a deposit of print medium onto the substrate, the printed deposit comprising an upper surface, modifying the upper surface of the printed deposit, for example by partially drying the printed deposit, and levelling the modified deposit to produce a flat feature.
STEAM TREATING PRINTED FIBROUS SHEET MATERIAL
Steam-treating printed fibrous sheet material to fix ink printed on the material includes conveying the printed material into a steam chamber on a conveyor with a surface containing condensed water. At least some of the condensed water is transferred to the sheet material on the conveyor.
