A need exists for a device that can prevent the uncontrolled discharge of melt, such as plastic melt, from nozzle apertures.
A further need exists for a device that can be used to ensure that melt does not enter a process chamber of an underwater granulator until the desired molten conditions, such as the necessary degree of plastication or melting of melt, are reached.
A further need exists for a device that controls the uncontrolled discharge of melt, is compact in design, and reduces thermal problems associated with the control of melt out of a nozzle.
The present embodiments meet these needs.
The present embodiments are detailed below with reference to the listed Figures.
