Abstract
Methods and apparatus for controlling a hem profile in roll-forming processes are described. An example roll-forming apparatus includes a first plurality of work rolls to form a first hem on a material and a second plurality of work rolls. One of the second plurality of work rolls is adjustable relative to an opposing work roll and to the first plurality of work rolls to adjustably control a profile of the first hem.
Claims20
A roll-forming apparatus, comprising:
- a base;
- first work rolls rotatably coupled to the base, the first work rolls to form a first hem on a material;
- second work rolls to control a profile of the first hem, one of the second work rolls is rotatably coupled to a block movably coupled to the base;
- and
- an actuator to move the block relative to the base and to move the one of the second work rolls relative to an opposing one of the second work rolls to enable the profile of the first hem to be continuously adjusted.

The apparatus of claim 11, wherein the actuator and the second actuator are independently operable.
A method, comprising:
- moving a material through first work rolls to form a first hem on the material, the first work rolls rotatably coupled to a base;
- moving the material through second work rolls to control a profile of the first hem, wherein one of the second work rolls is rotatably coupled to a block movably coupled to the base;
- and
- moving the block and the one of the second work rolls relative to an opposing one of the second work rolls to enable the profile of the first hem to be continuously adjusted.
