Patent ID: 7963140

Claim:
A handheld crimp on flange (COF) tool for crimping a weather strip onto a flange of a vehicle opening, the handheld COF tool comprising: a housing configured as a handle for use in holding the handheld COF tool, wherein said housing attaches at a first end thereof to a pressurized air source; a fixed crimp roller projecting from a second end of said housing, and rotatably mounted to said housing to rotate about a fixed axis in a first direction; a movable crimp roller projecting from said second end of said housing proximate to said fixed crimp roller and rotatably mounted to said housing to rotate about a movable axis in a second direction opposite said first direction, wherein said movable crimp roller is axially offset from and movable toward and away from said fixed crimp roller; a pneumatic motor encased within said housing and drivingly connected to said movable crimp roller and said fixed crimp roller, wherein said pneumatic motor is configured to convert pressurized air received from said pressurized air source into a rotational force to thereby rotate said movable crimp roller and said fixed crimp roller at a crimp speed; a pneumatic piston assembly encased within said housing and operatively engaged with said movable crimp roller, wherein said pneumatic piston assembly is configured to convert pressurized air received from said pressurized air source into a linear force to thereby move said movable crimp roller toward said fixed crimp roller at a crimp rate and thereby generate a crimp pressure between said movable crimp roller and said fixed crimp roller; and a hand lever disposed on said housing and operative to fluidly connect said pneumatic motor, said pressurized air source, and said pneumatic piston assembly; wherein said pneumatic motor is configured to selectively adjust said crimp speed, and said pneumatic piston assembly is configured to selectively adjust said crimp rate and said crimp pressure independent of said crimp speed and each other.
