Publication number: 20040223665Abstract: A reclosable bag includes front and rear panels joined to each other, and optionally includes inwardly extending side gussets. The bag includes a reclosable fastener assembly joined to the exterior of the bag, with the fastener assembly including cooperating, first and second fastener elements. The fastener elements are respectively secured to the front and rear panels of the bag, and permit an open mouth of the bag to be closed, and the top of the bag folded and maintained in a folded disposition by the cooperating fastener elements.Type: ApplicationFiled: May 7, 2003Publication date: November 11, 2004Applicant: Hudson-Sharp Machine Co.Inventors: Gerry J. Blohowiak, Peter J. Hatchell, Robert Craig Bayliss

Patent number: 6516850Abstract: An apparatus for applying strip fastener elements or zippers to web material includes an unwind stand holding a roll of film material, an infeed dancer arrangement of rollers, a zipper apparatus which conditions zipper material, cuts zippers and delivers zippers to a zipper feed apparatus. The zipper feed apparatus loads zippers into a sealing platen of a rotating turret. The rotating turret carries the zippers successively to a position adjacent a surface of the film and a seal bar presses the film to successive zippers to seal the zippers thereto while a new zipper is being received in a sealing platen of the turret at a loading station at a rotational position at a distance from the sealing station. The film with zippers attached is drawn downstream of the turret to a rewind dancer roll assembly and thereafter to a rewind stand for winding into a roll of zippered film.Type: GrantFiled: October 5, 1999Date of Patent: February 11, 2003Assignee: Hudson-Sharp Machine Co.Inventors: Gerry J. Blohowiak, Peter J. Hatchell, Sean Kevin Lemerand, Ernest H. Teske, Scott C. Romenesko

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

Patent number: 5388746Abstract: A separator/folder bag machine for developing individual, folded, plastic bags. A pair of high speed separation rollers, actuated by means of a servo motor driven eccentric linkage, engages a continuous plastic web to separate individual plastic bags formed tin the web. A pair of parallel, wide belts, and a pair of similar, overlying belts, engage both sides of the separated bags and transport the bags to a plurality of folding stations. Air jets at selected locations in the folder/separator controllably direct the bags through pairs of nip rolls to fold the bags along predetermined fold lines. Sensors in the folder/separator sense abnormal conditions and deactivate particular fold stations to reject improperly formed bags. A two speed slowdown mechanism at the discharge end of the separator/folder slows the folded bags to facilitate downstream handling.Type: GrantFiled: October 4, 1991Date of Patent: February 14, 1995Assignee: FMC CorporationInventors: Peter J. Hatchell, Ronald L. Lotto, Ernest H. Teske, Donald J. Bauknecht

Patent number: 5350928Abstract: An apparatus for use in a system for making bags or the like from a continuous web or sheet of film material, the system including a perforator for imparting series of transverse perforations onto the web at regularly spaced intervals, which comprises a spreader roll having a reduced diameter portion between two enlarged diameter portions; a switch device located adjacent the reduced diameter portion; wherein the large diameter portions cause each series of perforation to pull apart and form a gap as the web is drawn over the spreader roll; and wherein the switch device is capable of being activated each time a gap passes in close proximity to the switch device.Type: GrantFiled: February 11, 1993Date of Patent: September 27, 1994Assignee: FMC CorporationInventors: Peter J. Hatchell, Danford C. Anderson, Ronald L. Lotto

Patent number: 5230688Abstract: The invention has to do with the modification of well known heat sealing bag machines to increase the production capability of the machines. The use of servo drives for selected components of the bag machine permits the reduction of film acceleration and consequential peak film velocity, thus allowing faster machine cycles at the same film acceleration and consequential film velocity.Type: GrantFiled: November 1, 1989Date of Patent: July 27, 1993Assignee: FMC CorporationInventors: Peter J. Hatchell, Jeffrey L. Ross, Charles A. Sample
