90 Degree Deckle
It is known in the field of extrusion die design to use a deckle to adjust the effective coating width. Conventionally, the actuation mechanisms extend from the die in a direction parallel to the longitudinal axis of the die slot. Occasionally, such placement is inconvenient, e.g. when the machinery is up against an enclosure, or where other ancillary equipment restricts ready access.
The described invention answers this difficulty by providing an actuator, which extends perpendicular to the longitudinal axis of the die slot. While diverse mechanisms will suggest themselves to the ordinary artisan for accomplishing this, a deckle having an extension with a 45-degree angle slot, which is engaged by a lead screw, provides the needed function in a simple, robust manner.
Here are 5 different descriptive views:
View 1: This shows the deckle assembly mounted, and how it does not interfere with any of the components on the drive side.
View 2: This view shows the bottom half of the die body removed. Here we see how the mounting hole on the deckle assembly are placed at angle to increase there sealing accepts.
View 3: This view shows all components accept for the deckle body. In this view we are able to see as the handle on the deckle is turned, and is driven down, the deckle is driven into the die cavity, and thereby adjusting the width of coating.
View 4: In this view, the bottom half of the die is removed, and also the body of the deckle assembly. Here we see the...
