Patent number: 7644561Abstract: An apparatus for extracting air from within flexible packages having granular or otherwise flowable contents includes a package conveyor and a downwardly-open, vacuum extraction hood through which the packages are conveyed so that an upper portion of each package is moved through the extraction hood. The interior of the hood is joined in fluid communication with a vacuum source, so that air is extracted from within each package as it is conveyed through the hood. The present apparatus further includes a closing mechanism positioned immediately downstream of and in operative association with the extraction hood, whereby the upper portion of each package is maintained in a closed configuration prior to sealing, so that the interior of each package is not exposed to ambient conditions after it is conveyed out of the extraction hood, and prior to sealing of the upper portion.Type: GrantFiled: January 8, 2008Date of Patent: January 12, 2010Inventors: Peter Hatchell, Glenn Hayes, Ronald Hutjens

Patent number: 6132351Abstract: A process for making an internally-reinforced bag assembly includes formation of an outer bag body with a plurality of longitudinally oriented, laterally spaced pleats or tucks therein. An inner reinforcement layer is applied to the outer bag body after formation of the pleats, whereby the inner layer spans and overlaps each of the pleats. An apparatus embodying the present invention effects bag formation in this fashion. Advancement through the forming apparatus effects formation of the outer web into a gusseted tube, and formation of a square bottom seal. The completed bag assembly includes the inner reinforcement layer, which is dimensioned to define a circumference which is less than a circumference defined by the bag body. The resultant bag assembly resists bulging and deformation under the influence of particulate, granular, or other flowable products packaged therein.Type: GrantFiled: May 28, 1999Date of Patent: October 17, 2000Assignee: The Hudson-Sharp Machine Co.Inventors: Ronald L. Lotto, Scott Romenesko, Peter Hatchell

Patent number: 5588644Abstract: Rolls of individual plastic bags are formed on apparatus that overlaps the bags before the bags are fed into the roll to provide a compact roll of individual bags. The apparatus overlaps portions of the bags so that a plurality of bags can be continuously fed into the roll even though the bags are not mechanically connected end-to-end to adjacent bags on the roll.Type: GrantFiled: December 4, 1995Date of Patent: December 31, 1996Assignee: FMC CorporationInventors: Ronald L. Lotto, Ernest H. Teske, Peter Hatchell
