Abstract
A fusing apparatus in which particles are affixed substantially permanently to a moving sheet of support material. Each portion of the leading marginal region of the sheet of support material is advanced substantially simultaneously between a fuser roll and a backup roll. As the sheet a support material passes between the fuser roll and backup roll, the side marginal regions thereof advance at a greater velocity than the central region. In this manner, a force component substantially normal to the path of movement of the sheet of support material in the plane thereof, is applied thereto preventing wrinkling.
