A continuous printer including a framework supporting an endless platen and means to move material onto the platen for movement therewith. Printing means comprising an endless stencil screen mounted on spaced rolls are disposed adjacent to one run of the platen for printing the material and includes ink distributing means. The ink distributing means includes a housing removably supported on the framework and defining a substantially enclosed ink cavity disposed about an applicator roller journalled in the housing. A table supports the run of the platen opposite the printing means and a friction band of a material of a lower surface friction coefficient than that of the material of the platen is disposed between the runs of the platen and has a run which extends between the platen and the table and is movable with the platen for reducing friction between the platen and the table. Toothed means are provided for movement with the platen and mesh with toothed means on the screen supporting rollers to drive the rollers and to insure continued registration between the stencil screen and the material to be printed.
A printing device, a production unit and a production method of electronic parts suitable for production of precise electronic parts are provided. A squeegee is attached to a rotating machine, and is autorotated and self-driven, and moreover, a printing pressure is generated in the squeegee, and resin is strongly filled, thereby achieving a print having a precision-shape. Further, with a perforated plate as a boundary, upper and lower chambers are provided so as to control a pressure, thereby performing cutting and dispensing of the resin and achieving a print having a precision-shape. This method is applied to the packaging of electronic parts. A printing device E1 comprises: a roller 3 allowing a peripheral surface 32 to approach one side 21 of a circuit board 2; moving means 4 for horizontally moving the roller 3; rotating means 5 for allowing the moving means 4 to rotate the roller 3; a squeegee 6 rotatably supported along the peripheral surface 32 of the roller 3; and printing pressure generating means 7 for pressing the squeegee 6 to the circuit board 2 by a rotating reactive force of the roller 3.
This disclosure is directed to a rotary printing screen assembly adapted for use on a screen printing machine. The assembly includes a rotary screen having an associated squeegee disposed within the rotary screen to force the color therethrough. A roller flood bar is operatively disposed within the screen which is free to rotate relative to the screen during a printing operation to effect a flood stroke along the internal surface of the screen in advance of the squeegee.
