Abstract: An apparatus and method for extruding, cooling and cutting an extrusion using temperature feedback can include an extruder for producing an extrudate which can be fed through appropriate sizing, support and cooling devices, which can include one or more of a vacuum chamber, cooling chamber, and calibrators having internal cooling passages. The apparatus can also include a cutting blade, a programmable temperature controller for controlling the cooling of the extrudate based upon feedback on the temperature of the extrudate sensed near the cutting blade and/or prior to a device which feeds the extrusion through the system. The method can include sensing the temperature of the extrudate, at a point near the cutting blade and/or prior to the feed device, subsequent to extrusion being passed through the sizing, support and/or cooling devices.

Abstract: An apparatus and method for extruding, cooling and cutting can include an extruder for producing an extrudate which can be fed through appropriate sizing, support and cooling devices, which can include a vacuum chamber, cooling chamber, and calibrators, which can have internal cooling passageways. The apparatus can also include a cutting blade, a programmable temperature controller for controlling the temperature of the extrudate prior to being cut by the cutting blade, and a temperature sensor, which can be positioned near the cutting blade and provide feedback to the temperature controller. The method can include sensing the temperature of the extrudate, at a point near the cutting blade, after it is fed through the sizing, support and cooling devices and before being cut. Such feedback can be used to control the temperature of the extrudate such that the extrudate is maintained within a desired range of temperature as it is cut.
