摘要： A tray suitable for providing a uniform coating of predetermined thickness on sheet material includes a generally V-shaped trough for dispensing a fluid contained therein through a plurality of apertures formed through the bottom of the trough and spaced along its length. Along the outer surface of the apex of the V-shaped trough, there is formed a channel communicating with the apertures and defining a pair of spaced continuous blades extending along the length of the trough and spanning the apertures. The lands of material between the apertures of the trough are tapered to a point on the side of the trough adjacent the channel to provide a uniform supply of coating material within the channel. As the trough is moved across the surface of a sheet to be coated, the trailing blade which is spaced at a desired height from the sheet material, provides a uniform coating of fluid to the sheet.

摘要： Stencilling apparatus having a trough type fluid scoop positioned behind, parallel to, and spaced from the stencilling squeegee, the scoop being pivotally shiftable through a scooping motion to scoop up excess fluid after the squeegee is elevated. The pivotal shifting is from a first scoop position wherein an edge of the scoop serves as a flow coater to a second position wherein the scoop retains the fluid scooped.
摘要翻译： 具有槽形流体勺的搅拌装置，其位于平行于并且与间歇刮板的后方并且与间歇的刮板之间，勺子可旋转地移动通过舀取运动，以在刮板升高之后铲起多余的流体。 枢转换档是从第一勺位置，其中勺子的边缘用作流涂机到第二位置，其中铲斗保持舀取的流体。

摘要： Stencilling apparatus having a print and flow action relative to a combination squeegee and flow coater assembly, wherein excess stencilling fluid ahead of the squeegee can flow through the assembly, by flow over the squeegee into a control reservoir behind the squeegee and ahead of the trailing flow coater, and a controlled layer of the fluid flows from the reservoir beneath the lower edge of the flow coater onto the underlying stencil screen.
