Abstract
A sheet rolling device includes a mandrel that selectively retains the sheet stock between a sidewall of the mandrel and a gripper blade of the mandrel. The sheet rolling device also includes a sensor that detects a presence and an absence of the sheet stock near the mandrel, a controller operably associated with the mandrel so as to cause a motor to rotate the mandrel to wind the sheet stock around the mandrel, and an expansion leaf operably associated with the controller and situated along at least a portion of an exterior of the sidewall of the mandrel. Extension of the expansion leaf away from the sidewall increases an effective perimeter of the mandrel about which the sheet stock may be wound and retraction of the expansion leaf toward the sidewall decreases the effective perimeter of the mandrel about which the sheet stock may be wound.
