Publication number: 20120134607Abstract: The present invention was directed to an expandable package which facilitates packaging of compressible articles, such as sanitary products, disposable diapers and the like. The expandable package includes an outer bag body, and at least one inner expansion element, which is maintained in a folded condition so that articles within the package are maintained in a compressed state. The package includes at least one preferentially weakened area in the outer bag body, which when opened, permits the inner expansion elements to unfold, thus facilitating convenient separation and removal of individual articles from within the package by consumers.Type: ApplicationFiled: August 28, 2009Publication date: May 31, 2012Applicant: THE HUDSON-SHARP MACHINE CO.Inventors: Eric DeSmedt, Michele Allamprese

Publication number: 20100255973Abstract: A system for inspecting individual bags during stacking facilitates defect-free stacking of the bags for subsequent use with automated filling equipment. The present system includes a camera inspection system which is operated to inspect a predetermined portion of each bag, such as a header portion thereof, preferably in conjunction with stacking of each bag on an associated wicket. The present system is particularly suited for identifying bags having a folded corner and/or determining that only one of a pair of holes of a hag has been placed on the associated wicket.Type: ApplicationFiled: May 14, 2008Publication date: October 7, 2010Inventor: Eric DeSmedt

Patent number: 6793613Abstract: A block of bags for a product filling process includes a plurality of bags stacked in overlying relationship. Each bag of the block has a top edge, a bag mouth and opposite first and second side edges. First and second weakened segments extend from adjacent edge points on respective opposite lateral edges of the bag. A central line of perforations extends between inner ends of the first and second weakened segments. A tear-off region is defined between the central line of perforations and the top edge. During automatic filling of the bag, the weakened segments are torn to form an open bag mouth, and the central line of perforations is torn after filling to separate the bag from the block. The weakened segments can be cuts and are spaced from the lateral edges of the bag to define frangible bridges at the lateral edges, wherein the frangible bridges are broken during opening of each bag.Type: GrantFiled: February 15, 2002Date of Patent: September 21, 2004Assignee: Hudson-Sharp Machine Co.Inventors: Eric DeSmedt, Eric Loppnow

Patent number: 6601707Abstract: A block of bags for a product filling process includes a plurality of bags stacked in overlying relationship. Each bag of the block has a top edge, a bag mouth and opposite first and second side edges. First and second edge lines of perforations extend from edge points on respective opposite lateral edges of the bag. The edge points are spaced closely to the bag mouth of the bag. A central line of perforations extends between inner ends of the first and second edge lines of perforations. The central line of perforations is offset from the edge points, away from the bag mouth. A tear-off region is defined between the central line of perforations and the top edge. During automatic filling of the bad, the edge lines of perforations are torn to form an open bag mouth, and the central line of perforations is torn after filling to separate the bag from the block.Type: GrantFiled: February 16, 2001Date of Patent: August 5, 2003Assignee: Hudson-Sharp Machine Co.Inventor: Eric DeSmedt

Patent number: 5447486Abstract: In an apparatus for making plastic bags or the like from a continuous film of material comprising a sealing drum having at least one seal bar for imparting transverse seals to the film at regularly spaced intervals and a perforator having a rotatable perforator blade for imparting transverse perforations to the film at regularly spaced intervals, the film comprising print marks appearing thereon at regularly spaced intervals, an apparatus and method are disclosed for tracking the positions of each print mark and each perforation and comparing the difference between these positions to a desired difference and thereafter adjusting the angular position of the perforator blade until the difference between the positions of each print mark and each perforation is equal to the desired difference to thereby maintain a desired spacing between each print mark and each perforation.Type: GrantFiled: November 12, 1993Date of Patent: September 5, 1995Assignee: FMC CorporationInventors: Danford C. Anderson, Peter J. Hatchell, Emiel Lambrecht, Eric DeSmedt
