Variable crimp on flange tool

A crimp on flange (COF) tool for engaging and attaching a weather strip onto a flange, the COF tool comprising:

• a housing configured to attach to a power source;
• a fixed crimp roller projecting from said housing and rotatably mounted thereto to rotate about a fixed axis in a first direction;
• a movable crimp roller projecting from said housing and rotatably mounted thereto to rotate about a movable axis in a second direction opposite said first direction, wherein said movable axis is axially offset from and movable relative to said fixed axis;
• a motor encased at least partially within said housing and drivingly connected to said fixed and movable crimp rollers, wherein said motor is configured to rotate said fixed and movable crimp rollers at a crimp speed;
• and
• a piston assembly encased at least partially within said housing and operatively engaged with said movable crimp roller, wherein said piston assembly is configured to selectively move said movable crimp roller relative to said fixed crimp roller at a crimp rate and generate a crimp pressure between said fixed and movable crimp rollers;
• wherein said motor and said piston assembly are configured such that said crimp rate, crimp speed, and crimp pressure are independently selectively adjustable.

A crimp on flange (COF) tool for crimping a weather strip onto a flange of a vehicle opening, the COF tool comprising:

• a housing configured to attach 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 and fixed crimp rollers, 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 and fixed crimp rollers at a crimp speed;
• and
• 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 and fixed crimp rollers;
• 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 crimp pressure independent of said crimp speed and each other.
