Filed:

Jan 7, 1999

Appl. No.:

9/226484

Inventors:

Sean R. Brookes - North Canton OH
Kilian Mendel - Wadsworth OH
Robert L. Sadinski - Tallmadge OH

Assignee:

Owens Corning Fiberglass Technology, Inc. - Summit IL

International Classification:

B29B 742
B29B 760

US Classification:

366 764

Abstract:

An extruder such as a reclaim extruder includes a feed section with a throat into which a force feeder is positioned to compact and feed reclaim material at a higher and more productive rate. The force feeder includes three side-by-side augers pointed at the extruder screw axis. An AC variable frequency drive motor drives a double sided cog belt in serpentine fashion around respective pulleys or sheaves for the augers. Two of the augers are of one hand rotated in one direction, and one of opposite hand rotated in the opposite direction. The pulleys or sheaves are of different size so that each auger rotates progressively faster moving down stream of the extruder screw. Each auger is positioned in a closely fitting compression tube each provided with an inlet opening. The force feeder is conveniently angularly positioned through the wall of a collection box between a hopper and the throat of the extruder.

UC Industries, Inc. - Parsippany NJ

International Classification:

B29C 4716

US Classification:

2641761

Abstract:

An extrusion die and flow control method incorporates a flow control in the form of a flow diverter which extends transversely across the flow path. The diverter forms part of a window upstream of the die lips and provides a slight tapering enlargement which may be moved along the window across the flow path from one side to the other or preferably, from the center symmetrically outwardly, or vice versa, to divert flow from the center proportionally to the edges without changing the total cross sectional area of the window. The window is formed by a pair of axially rotatable cylindrical bars recessed in the die body which each have a flat forming the enlargement. In the preferred form the flat is helical. The helical flats are opposed or matched so that as the bars contra-rotate synchronously the enlargement will move across the window. Where the movement is symmetrical from the center or axis to each transverse edge and vice versa, the helical matching flats on each bar turn in opposite directions on each end of the middle of each bar.

International Classification:

US Classification:

264 407

Abstract:

A foam extrusion apparatus and method in which extrudate is extruded into a sealed chamber which may be subjected to pressure variation such as a vacuum with the controlled shaping of the plastic being obtained by power driven rolls within the chamber downstream of the die. Because of the harsh environmental conditions within the chamber it is desirable that the shaping or forming rolls be driven by an externally powered source which will therefore be not subject to the pressure, vacuum, or other deliterious conditions found within the chamber. Moreover, because of the external position of the drive with regard to the chamber, the entire system need not then be shut down in order to open the chamber and make the required adjustments or repairs. The chamber is preferably the upper end of a barometric leg into which the extrudate passes. The upper end of the chamber is closed by one or more bulkheads which are movable toward and away from the upper end of the chamber.
