US Patent:

7075035, Jul 11, 2006

Filed:

Nov 2, 2004

Appl. No.:

10/979379

Inventors:

Michael A. Kalinowski - Merrimack NH, US

Assignee:

Shanklin Corporation - Ayer MA

International Classification:

H05B 3/08

US Classification:

219241, 219512, 219494, 219243

Abstract:

Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors the length of the sealing wire, and adjusts the current applied to the wire, responsive to that monitored length.

International Classification:

H05B 1/02

Abstract:

Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors both the actual current passing through the wire, and the length of the sealing wire, and adjusts the current applied to the wire, responsive to those monitored inputs. The usage of the sealing machine is also monitored and the application and amount of current flowing to the wire is varied based on this usage.
