Abstract
An extrudate cooling tank having cooling water chambers adapted for running passage of extrudate serially therethrough at a preselected regulated variable pressures with water in the chambers being at different temperatures, and a wheel-servo motor combination hingedly connected to the chamber and being movable with respect thereto between a first position with the wheel engaging running extrudate and a second position with the wheel remote from engagement with the extrudate.
Claims15
An extrudate cooling tank, comprising:
- a) a controlled pressure first temperature water chamber adapted for running passage of an extrudate therethrough;
- b) a controlled pressure second temperature water chamber adapted for continued running passage of the extrudate therethrough;
- c) a controlled pressure third temperature water chamber adapted for further continued running passage of the extrudate therethrough;
- d) a rotatable extrudate puller wheel positionable for receivably engaging the running extrudate in one of the water chambers and controlling a speed of the running extrudate as the extrudate engagingly moves with the rotatable puller wheel;
- and
- e) a variable speed motor connected to the puller wheel for controlling a speed thereof to regulate at least one physical parameter of the extrudate, the motor being rotatably connected to the tank for arcuate unitary movement of the motor and puller wheel together between a first position at which the puller wheel engages the running extrudate and a second position at which there is no engagement of the running extrudate by the puller wheel.
A method of controlling a speed of a running extrudate during cooling thereof comprising:
- pivotally moving a motor-puller wheel assembly between a first position at which the wheel engages the running extrudate within a controlled temperature bath thereby cooling the extrudate to regulate at least one of extrudate outer diameter, wall thickness, concentricity, ovality, and shrinkage, and a second position at which the puller wheel does not engage the running extrudate to regulate extrudate physical parameters.
An extrudate cooling tank, comprising:
- a) a plurality of cooling water chambers adapted for running passage of an extrudate serially therethrough, a respective first cooling water chamber being at a preselected regulated variable pressure and respective remaining cooling water chambers being at least at atmospheric pressure, water in the chambers being at different temperatures;
- b) a rotatable extrudate puller wheel-servo motor combination hingedly connected to one of the remaining cooling water chambers and movable with respect thereto between two positions, the combination in a first position positioning the puller wheel to receivably engage the running extrudate to rotatably controlling a speed of the running extrudate by contact therewith, the combination in a second position positioning the puller wheel remote from a position of engagement with the running extrudate.
A two chamber extrudate cooling tank, comprising:
- a) a controlled pressure first temperature water chamber adapted for running passage of an extrudate therethrough;
- b) a controlled pressure second temperature water chamber adapted for continued running passage of the extrudate therethrough;
- c) a rotatable extrudate puller wheel positionable for receivably engaging the running extrudate and controlling a speed of the running extrudate as the extrudate engagingly moves with the rotating puller wheel;
- d) a plurality of guide wheels positioned in the tank downstream of the puller wheel to successively contactingly guide the running extrudate through the tank;
- and
- e) a variable speed motor connected to the puller wheel for controlling a speed thereof, the motor being rotatably connected to the tank for arcuate unitary movement of the motor and puller wheel together between a first position at which the puller wheel engages the running extrudate and a second position at which there is no engagement of the running extrudate by the puller wheel.
