Apparatus For Fabricating A Wide-Mouth Plastic Container From A Stretch Blow-Molded Intermediate Article

US Patent:
4865533, Sep 12, 1989
Filed:
Dec 9, 1987
Appl. No.:
7/130310
Inventors:
Philip G. Hart - Hartsville SC
Virgil L. Davis - Hartsville SC
Assignee:
Sonoco Products Company - Hartsville SC
International Classification:
B29C 4974
US Classification:
425527
Abstract:
An apparatus is provided for fabricating a wide-mouth plastic container, having an annular flange extending radially outwardly at the wide-mouth, from a stretch blow-molded intermediate article, having a dome-like accommodation portion extending radially-outwardly at a flange area and upwardly and inwardly from the wide-mouth of a generally cylindrical body portion. The apparatus provides for a two stage cutting and trimming operation which produces a precision concentric uniform flange around the wide-mouth of the fabricated container and provides for alternately and simultaneously performing the fabricating operations to provide a desired speed of operation of the apparatus.

Method And Apparatus For The Manufacture Of Paperboard Tubes Having Controlled Outside Diameter

US Patent:
5106356, Apr 21, 1992
Filed:
May 30, 1991
Appl. No.:
7/707686
Inventors:
David E. Rhodes - Hartsville SC
George E. Lennon - Hartsville SC
Philip G. Hart - Hartsville SC
Assignee:
Sonoco Products Company - Hartsville SC
International Classification:
B31C 108
US Classification:
493 8
Abstract:
The invention provides a method and apparatus for the manufacture of helically wound paperboard tubes having a highly uniform outside diameter. The method of the invention involves the application of controlled compressive force to at least one of the paperboard plies fed to a helical winding operation in order to control the thickness of the ply or plies and thereby control the outside diameter of the helically wound tube. In one preferred apparatus embodiment of the invention, the compressive force applied to the paperboard ply is applied via a pair of cooperating compression rolls. The nip between the two cooperating rolls is controllably varied by mounting one of the rolls for rotation about a shaft which is rotatable about an eccentric axis which is parallel to and offset from the axis of rotation of the roll. The rotation of the shaft thus causes the roll to move toward or away from the other cooperating roll and thereby varies the nip spacing between the rolls.
