VISCOSITY MEASUREMENT DEVICE, PRINTING LIQUID SUPPLY DEVICE, PRINTING LIQUID CIRCULATION DEVICE, PRINTING MACHINE, AND PRINTING LIQUID VISCOSITY ADJUSTMENT METHOD
A viscosity measurement device includes a measurement tool having a pump for feeding a printing liquid by pressure. The viscosity measurement device includes a passage part having a first passage part in which a flow path cross-sectional area for the printing liquid is set at a first area, and a second passage part in which a flow path cross-sectional area for the printing liquid is set at a second area smaller than the first area and which is arranged on an upstream side in a supply direction of the printing liquid with respect to the first passage part, the passage part being interposed in the supply path and arranged upward toward a downstream side in the supply direction of the printing liquid; and a sensor attached to the second passage part and measuring the fall time of the measurement tool in a prescribed vertical region in the second passage part.
SOLDER PASTE BEAD RECOVERY SYSTEM AND METHOD
A stencil printer is configured to print an assembly material on an electronic substrate. The stencil printer includes a frame, a stencil coupled to the frame, a support assembly coupled to the frame, and a print head gantry coupled to the frame. The print head gantry includes an elongate beam that rides along rails provided on 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 print head assembly includes a print head having a squeegee blade assembly configured to roll solder paste along the stencil. The stencil printer further includes a solder paste bead recovery system configured to remove a bead of solder paste from a top surface of the stencil and to deposit the bead of solder paste onto a new replacement stencil.
PRINTING MACHINE AND INK FOUNTAIN DEVICE THEREOF, AND METHOD FOR CLEANING PERIPHERY OF INK FOUNTAIN
An ink fountain of an ink fountain device is provided with a fixed frame; a plate slidable on the upper surface of the plate; and an advancement and retraction mechanism advancing and retracting the plate with respect to the frame. The advancement and retraction mechanism comprises: a motor; a cam fixed to the output shaft of the motor which is integrally rotatable by rotation of the output shaft and has a cam surface shifted from an exact circle; and a rod in contact with the cam surface and advancing and retracting by the cam. The plate advances and retracts with respect to the frame by the advancement and retraction of the rod.
ROTARY MACHINE WITH IMPROVED SHAFT
A rotary machine is disclosed, which includes a rotary shaft having a rotation axis, a first shaft end, and a second shaft end; a first bearing arrangement at the first shaft end; a second bearing arrangement at the second shaft end; a coupling flange mechanically connected to the first shaft end. The coupling flange is mechanically connected to the first shaft end by means of a first axial-contact coupling.
Roller arrangement, a method of forming a pattern, a method of printing a pattern and apparatus for printing a pattern
A roller arrangement for printing apparatus comprises a first roller. The first roller comprises a plurality of cells. Each of the plurality of cells receives an amount of a coating material. The roller arrangement further comprises an extractor to remove at least a portion of the coating material from a selected set of the plurality of the cells.

TWO-COMPONENT DRIP EDGE
The invention relates to a device having a two-component drip edge. One side of the drip edge is formed by a material having an attractive behavior with respect to a liquid and the opposite side of the drip edge is formed from a material having a repulsive behavior with respect to the liquid. This design yields an improved drip effect.

DEVICE FOR APPLYING A FLUID TO A ROLLER
A fluid distribution device, for applying a fluid onto a transfer roller (2), comprises an elongated chamber (10), at least one inlet (31) for letting a fluid into the chamber (10), a longitudinal opening extending in the axial direction and adapted to face a transfer roller (2) so as to allow fluid to exit the chamber and contact the transfer roller, and at least one wiper blade (11) extending along at least a portion of the longitudinal opening. The chamber comprises, at each of the two axial ends of the chamber, a wall (15) separating the chamber (10) from a cavity (16), wherein the wall (15) has a wall surface (15A) arranged to face the transfer roller (2) when the device is in use, the wall (15) being dimensioned so that the wall surface (15A) will be distanced from the transfer roller when the device is in use, so as to allow fluid to be present in a gap (20) between the wall surface (15A) and the transfer roller.
