Abstract
A material aligning device having a plurality of sine waves, wherein the sine waves can be in the form of protrusions repeating along an outer surface of a roller. The material aligning device provides an oscillation to the material sheet moving on it to cancel its vibrations, which allows for faster and improved alignment while printing, web converting, and during other similar processes. The material aligning device also relieves the high amount of tension typically necessary for the printing, converting, and other similar material processing using machines. The reduction in tension also reduces the likelihood of the material sheet being overly stretched or for it to rip.
