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.
Claims22
A roll-forming apparatus, comprising:
- a base;
- a first work roll rotatably coupled to the base, the first work roll having a first planar surface in a first plane;
- a second work roll coupled to the base, the second work roll having a second planar surface opposite the first planar surface in a second plane, a recess opposite the first planar surface, and a third planar surface opposite the first planar surface in the second plane, the recess including a first surface of the recess having a first length that extends from the second planar surface, a second surface of the recess, and a third surface of the recess having a second length greater than the first length and extending from the third planar surface, the second surface of the recess disposed between the first surface of the recess and the third surface of the recess, wherein the second work roll 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 second work roll to different positions in which the second work roll engages a material to enable a profile of a hem of the material disposed in the recess to be continuously adjusted to different profiles between an open hem profile and a closed hem profile, the actuator to move the second work roll relative to the first work roll.

An apparatus comprising:
- a base;
- a first work roll rotatably coupled to the base, the first work roll having a first planar surface in a first plane;
- a second work roll rotatably coupled to a block movably coupled to the base, the second work roll having a second planar surface opposite the first planar surface in a second plane, a recess opposite the first planar surface, and a third planar surface opposite the first planar surface in the second plane, the recess including a first surface of the recess having a first length that extends from the second planar surface, a second surface of the recess, and a third surface of the recess having a second length greater than the first length and extending from the third planar surface, the second surface of the recess disposed between the first surface of the recess and the third surface of the recess;
- and
- an actuator to move the block relative to the base and to move the second work roll to different positions in which the second work roll engages a material to enable a profile of a hem of the material disposed in the recess to be continuously adjusted to different profiles between an open hem profile and a closed hem profile, wherein the actuator extends through the block and threadably engages the base.

An apparatus comprising:
- a base;
- a first work roll rotatably coupled to the base, the first work roll having a first planar surface in a first plane;
- a second work roll rotatably coupled to a block movably coupled to the base, the second work roll having a second planar surface opposite the first planar surface in a second plane, a recess opposite the first planar surface, and a third planar surface in the second plane, the recess being asymmetrical between the second planar surface and the third planar surface and extending from the second planar surface to a first depth at a first side of the recess and extending from the third planar surface to a second depth at a second side of the recess, the second depth different than the first depth;
- and
- an actuator to move the block relative to the base and to move the second work roll to different positions in which the second work roll engages a material to enable a profile of a hem of the material disposed in the recess to be continuously adjusted to different profiles between an open hem profile and a closed hem profile, the actuator to move the second work roll relative to the first work roll.
