  • Patent number: 7963140
    Abstract: A variable crimp on flange (COF) tool is provided for engaging and attaching a weather strip and like structures onto a flange. The COF tool includes a housing with two or more crimp rollers that project therefrom. For example, a fixed roller is mounted to the housing to rotate in a first direction, while a movable roller is mounted to the housing to rotate in a second, opposite direction. The movable roller is axially offset from and movable relative to the fixed roller. A driving mechanism, such as a pneumatic motor, is encased within the housing, and operates to rotate the crimp rollers. A biasing mechanism, such as a pneumatic piston assembly, is also encased within the housing, and operates to move the movable crimp roller relative to the fixed crimp roller. The COF tool is engineered such that the crimp speed, crimp rate, and crimp pressure are independently adjustable.
