Definitions
- Figure 3 is similar to Figure 2, but illustrates an alternative exit slot arrangement for a low viscosity bottom layer
- the other layers are discharged from respective slots 20, 22, 24 and 26, and are inverted in sequence from that of conventional curtain- or bead- coating.
- the support 14 is inclined to the horizontal so that the angle of application of the curtain to the support, a, is not 0°, that is, the curtain 12 is applied at a forward application angle.
- an exit slot arrangement is shown in which the bottom layer 16 is directly applied to the upstream side of the curtain as it leaves the hopper lip 36.
- the bottom layer 16 is discharged from an additional slot 30.
- This slot 30 is formed by inserting a sub-lip element 32 beneath the overhang 34 at the front of the hopper slide 28. In this case, the slot exit is positioned exactly at the hopper lip 36 as shown.
