Patent number: 7455636Abstract: An apparatus for application of zippers to film material 10 comprises an applicator bar 22 for presenting pre-cut lengths of zipper 26 to the film and a heated sealing bar 34 for sealing the pre-cut lengths to the film. The applicator bar, the sealing bar, feed rollers 30a, 30b and a zipper cutter 32 are mounted for movement with the film on a linear motor 14. A pneumatic cylinder 18 raised the application bar towards the film 10. The applicator bar moves in direction C to apply the zipper to the film 10 moving in direction A, then moves with the sealing bar and the film in direction B, away from the film in direction C?, back to its starting position in direction B?, then towards the film again in direction C. A further length of zipper may be fed to the applicator bar at any time after the bar has moved away from the film in direction C? and therefore during an end portion of the forward stroke of the motor, or during its return stroke.Type: GrantFiled: January 21, 2005Date of Patent: November 25, 2008Assignee: Illinois Tool Works Inc.Inventor: Murray Edward Bruce Leighton

Patent number: 7430844Abstract: A method of making and filling reclosable packages using a duplex machine includes the steps of providing a zipper profile, package film and a plurality of sliders; feeding the zipper profile; applying the sliders to the zipper profile; coupling the zipper profile to the folded web; sealing two edges of the folded web to form adjacent pouches; filling the pouches; sealing the pouches proximate a third edge thereof; and separating the pouches in order to form individual packages. The method employs a single rotating slider applicator having a programmable servo motor which is programmed in order to synchronize the application of the sliders to the moving zipper profile with the two at a time form, fill, seal and separate packaging operations of the duplex machine. A duplex machine is also disclosed.Type: GrantFiled: April 12, 2007Date of Patent: October 7, 2008Assignee: Alcoa, Inc.Inventors: James E. Buchman, Paul A. Tilman
