Sheet processing apparatus, method of use, and plastically deformed sheet

A method of plastically deforming a work piece, comprising

• providing an apparatus comprising,
• at least two cylindrical guide rolls rotatable in a first direction, each of said cylindrical guide rolls having an outer circumference;
• a bendable strip having at least one surface in communication with a portion of the outer circumference of each of the at least two guide rollers, said bendable strip being capable of movement with the at least two guide rollers in the first direction and exerting a force upon a work piece,
• a cylindrical feeding roll rotatable in a second direction opposite to the first direction, said cylindrical feeding roll having an outer circumference,
• a plastic deformation passage having an first surface and a second surface, at least a portion of the first surface being defined by the bendable strip, and at least a portion of the second surface being defined by the outer circumference of the first cylindrical feeding roll,
• rotating the at least two cylindrically guide rolls in a first direction and the cylindrical feeding roll in a second direction,
• propelling a work piece into the plastic deformation passage by the motion of one or both of the bendable strip or the feeding roll,
• plastically deforming the work piece in the plastic deformation passage, and
• removing a plastically deformed work piece from the plastic deformation passage.

An apparatus for plastic deforming a metallic sheet, comprising

• at least two cylindrical guide rolls rotatable in a first direction, each of said cylindrical guide rolls having an outer circumference;
• a bendable strip having at least one surface in communication with a portion of the outer circumference of each of the at least two guide rollers, said bendable strip having a tension force to facilitate movement of the bendable strip with the at least two guide rollers in the first direction,
• a first cylindrical feeding roll rotatable in a second direction opposite to the first direction, said first cylindrical feeding roll having an outer circumference,
• a plastic deformation passage having a first surface, a second surface, and a channel, at least a portion of said first surface being defined by the bendable strip, and at least a portion of said second surface being defined by the outer circumference of the first cylindrical feeding roll, said channel being defined by an upper and lower die, said upper die being in communication with a portion of the bendable strip positioned between the at least two cylindrical guide rolls and said lower die being in communication with the outer circumference of the feeding roll,
• wherein the bendable strip exerts a force on a metallic sheet and one or both of the bendable strip or the cylindrical feeding roll when under motion propel the metallic sheet into the plastic deformation passage.
