Method And Apparatus For Balancing Flowing Conditions Of Laminar Flowing Materials

Method And Apparatus For Balancing Flowing Conditions Of Laminar Flowing Materials

US Patent:
6503438, Jan 7, 2003
Filed:
Jun 28, 2001
Appl. No.:
09/894538
Inventors:
John P. Beaumont - Harborcreek PA
David A. Hoffman - Erie PA
Assignee:
Beaumont Runner Technologies, Inc. - Erie PA
International Classification:
B29C 4530
US Classification:
2642971, 2642972, 2643288, 26432812, 366336, 366441, 425572, 425588, 425464
Abstract:
A tool structure or tool insert has a runner system which includes at least one branching runner which branches in at least two directions forming at least a first pair of branch runners for receiving laminar flowing material for the formation of a product. Each branch runner is at a position in the runner system such that it receives material having significantly similar conditions from side-to-side of a bisecting plane of that runner which bisects the cross section of at least a portion of the length of that branch runner. This material also has dissimilar conditions from side-to-side of a perpendicular plane of each branch runner which is perpendicular to the bisecting plane of that runner with the perpendicular plane of each branch runner also bisecting the cross section of the same portion of the length of each branch runner that the bisecting plane bisects. A repositioner in the tool or tool insert repositions the dissimilar conditions of the laminar flowing material to preselected positions in circumferential directions around the center of the flow paths of each runner of each pair of branch runners. Each pair of branch runners is joined at a location on each runner of each pair which causes the flow from each of these runners to form a half of a joint stream of material which has conditions across its flow path that are significantly balanced from side-to-side of two perpendicular planes which bisect the flow path of the joint stream.
