ABSTRACT:
An apparatus in which sheet material is decurled. The apparatus includes a rod deflecting a belt to define a nip therebetween. The belt is entrained about a part of spaced rollers. A pair of baffle plates are located at the entrance to the nip and at the exit to the nip. The rod is adapted to translate in a vertical direction. As the rod translates, the degree of deflection is varied and the bend of the sheet adjusted. The baffle plates at both the exit and entrance regions to the nip pivot in unison with the translation of the pivot rod so as to adjust the orientation of the sheet entering and leaving the nip.
