Publication number: 20080093018Abstract: A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a single sealing zone, and an weakening zone disposed within the single sealing zone. The single sealing zone may be a heated perforator, includes a heating wire. The heating wire may be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.Type: ApplicationFiled: November 9, 2007Publication date: April 24, 2008Applicant: CMD CorporationInventors: Paul SELLE, Kenneth RADTKE, Charles SAUDER, Paul JOHNSON, Christopher WHITE, Arvid JOHNSON, Gregory PRELLWITZ, Michael STICKNEY, Thomas JANSEN, Christopher SAUCIER, Terry LEITZKE, Bradley SCHMOLL, Chris SCHRLIES, Gregory JOHNSON, Scott GRASSE

Patent number: 7326162Abstract: A plastic bag making machine is disclosed, and includes a dancer assembly that receives film from which the bags are to be made. The film travels from the dancer assembly to a drum-in nip and then to a sealing drum. After the sealing drum, the film travels to a drum-out nip. Then the film travels to a device-in nip, vertically through a processing device, and then to a device-out nip. A controller is connected to and controls the drum-in nip, the drum-out nip, the device-in nip, the device out nip, the dancer assembly and the sealing drum (including the seal bars and/or the sealing blanket drives). The controller includes a memory in which at least one set of operating parameters used to control the machine is stored.Type: GrantFiled: November 16, 2005Date of Patent: February 5, 2008Assignee: CMD CorporationInventors: Charles Sauder, Edward Clemons, Michael Stickney

Publication number: 20070167304Abstract: A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have, connected thereto, a source of power that is at an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire may be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.Type: ApplicationFiled: January 13, 2006Publication date: July 19, 2007Inventors: Paul Selle, Kenneth Radtke, Charles Sauder, Paul Johnson, Christopher White, Arvid Johnson, Gregory Prellwitz, Michael Stickney, Thomas Jansen, Christopher Saucier, Terry Leitzke, Bradley Schmoll
