Patent number: 7213384Abstract: A device for producing tubular bags filled with bulk goods from continuous foil tubes. The device includes a pair of sealing tools that seal or weld the foil tubes in bag-length intervals. A pair of closing bars connected to the sealing tools are biased toward each other and press the foil tubes before the sealing tools are closed. A stripper is provided to remove the residue of the bulk goods from the area of the seal by a wiping motion in the direction of bag movement through the device. The closing bars are connected to the stripper so that through a closing movement of the closing bars, the stripper is pulled along in the run direction of the foil while touching the foil to strip the area to be sealed before the sealing tools close.Type: GrantFiled: April 19, 2004Date of Patent: May 8, 2007Assignee: CMD CorporationInventors: Thomas Matheyka, Christian Helwig

Publication number: 20050115201Abstract: Apparatus for processing continuously fed elongate material, such as forming sealed bags from continuously fed film tubes, uses at least one pair of orbital tools that are cantilevered from tool drives (e.g., crank arms) at one edge of the material, extending transversely across the direction of material travel to engage opposite faces of the material. During material engagement the tools run synchronously with the moving material, but may be returned upstream rapidly to reengage the material for the next processing cycle. In order to achieve a higher throughput an additional pair of tools can be used, cantilevered and driven from the opposite edge of the material, maintaining the same processing (e.g., sealing) time. Through this arrangement the tools on opposing sides can alternate contact with the material and be run independently of each other.Type: ApplicationFiled: December 9, 2004Publication date: June 2, 2005Inventors: Christian Helwig, Thomas Matheyka
