Patent number: 7344671Abstract: The invention is specially directed towards intermittent motion packaging machines where the packages are momentarily immobilized at a forming station for the time duration of the package sealing and cutting. The polymeric sheets or films are sealed and cut after being exposed to a laser beam in a controlled and optimized manner. The laser beam is shaped with appropriate optical elements to provide a desired intensity profile in the section of the films to be sealed or sealed and cut. With this method, a package can be sealed and cut simultaneously in one exposure step. An optical clamp holds the films together while they are being sealed by the laser. The optical clamp can reflect back to the films, partially or totally, the laser beam intensity that has not been previously absorbed. The optical clamp further allows to monitor the sealing and cutting process while the process is being performed.Type: GrantFiled: November 26, 2003Date of Patent: March 18, 2008Assignee: Glopak Inc.Inventors: Roland Basque, Alain Cournoyer, Marc Levesque

The forming apparatus has contact surface geometry that is contacted by the film as it travels thereacross configured to ensure smooth forming of the film into the sleeve. Smooth forming of the film into the sleeve is achieved, in part, by reducing longitudinal tensile forces in the film, by selecting the contact surface geometry to minimize transverse variations in tensile forces in the film, and by having contact edges of the contact surfaces shaped to reduce unnecessary stresses in the film.Type: GrantFiled: July 25, 2003Date of Patent: February 28, 2006Assignee: Kraft Foods Holdings, Inc.Inventor: Christian Laplace

Patent number: 7000366Abstract: A decoration correction method for a form-and-seal unit for producing sealed packages of a pourable food product from a tube of packaging material fed along a feed path, and having two pairs of jaws movable along the feed path and opened and closed so as to travel, cyclically and alternately with each other, along a form-and-seal portion along which the pairs of jaws are closed and travel integrally with the tube, and along a repositioning portion along which the pairs of jaws open and move with respect to the tube. To make a decoration correction, a nominal trajectory of the jaws is modified along the repositioning portion on the basis of a position error of the tube with respect to a nominal position. A first solution provides for correcting the travel of the jaws by selectively modifying the amplitude of the trajectory; and a second solution provides for correcting the phase of the jaw trajectory.Type: GrantFiled: June 13, 2002Date of Patent: February 21, 2006Assignee: Tetra Laval Holdings & Finance S.A.Inventors: Davide Borghi, Behrooz Faskhoody, Bo Hellberg

Patent number: 6966166Abstract: This is a high-speed, multi-lane machine and method for the continuous forming, filling and sealing of plastic or film pouches of various sizes commonly used to hold fluids, liquids, and viscous materials or other substances. The machine includes a film roll station, a pump station, a side seal station, a pull wheel station, a cross seal station, and a cross cut station. The invention provides for continuous production of pluralities of pouches without stops or delays by utilizing one or more moveable reciprocating carriages that travel with the flow of film through the machine, the carriages supporting each of the side sealing, cross sealing, and cross cutting stations. Coordination of the various stations is accomplished through electronic computer control, working in conjunction with a plurality of motion imparting devices such as servo motors, cam systems, linkages and the like.Type: GrantFiled: March 26, 2004Date of Patent: November 22, 2005Assignee: SWF Companies, Inc.Inventor: Etienne Kissling

Patent number: 6935086Abstract: A double-bag package, and method for manufacturing same, constructed by modification to existing vertical form and fill packaging machines and perforation knives. In a preferred embodiment, the invention involves producing a double-bag package from a single sheet of packaging film by feeding a roll of film having graphics printed sideways rather than vertically into a vertical form, fill and seal packaging machine and using a novel perforating/cutting knife to alternately cut and perforate transverse seals. The perforating/cutting knife has teeth in the shape of oblique triangular pyramids, with each tooth having three cutting edges. The perforating/cutting knife produces self-correcting T-shaped perforation patterns capable of capturing and redirecting errant tears for fail-safe directional separation.Type: GrantFiled: November 25, 2003Date of Patent: August 30, 2005Assignee: Frito-Lay North America, Inc.Inventors: Frank Mathew Brenkus, Anthony Robert Knoerzer, Garrett William Kohl, Steven Kenneth Tucker

Patent number: 6931820Abstract: An apparatus for attaching discrete lengths of zipper at spaced intervals across a web of bag making film has an endless belt supported between a pair of pulleys for moving zipper segments into position on the web. The zipper segments are cut from a zipper supply and fed into a nip between the endless belt and the web top surface. After a zipper segment is deposited into position on the web, the endless belt is raised. A vertically movable sealing bar below the web is raised into position to heat the web to seal the zipper to the web after which the sealing bar is lowered. The web then advances and the process is repeated.Type: GrantFiled: February 13, 2003Date of Patent: August 23, 2005Assignee: Illinois Tool Works Inc.Inventor: Victor Delisle

Patent number: 6904737Abstract: A dispensing apparatus is provided suitable for dispensing at least first and second components in desired ratios especially for multi-component packaged food products. The apparatus comprises a hopper having an outlet at its lower end and a first auger having a hollow shaft disposed within the hopper having component conveying flights and a drive means for rotating the auger. A first component is conveyed by the auger flights and dispensed at an outlet while a second component is conveyed though a hollow shaft of the auger. The apparatus can include a second rotationally driven auger that is positioned within the hollow shaft of the first auger having conveying flights. The second component can be conveyed via the second auger within the hollow shaft. The second auger's shaft also can be hollow whereby a third component can be conveyed through the second hollow shaft of the second auger.Type: GrantFiled: August 1, 2002Date of Patent: June 14, 2005Assignee: General Mills, Inc.Inventors: Michael D.
