ABSTRACT:
In a chute feed apparatus for carding engines, cards and like machines, there is disclosed means for changing the widthwise configuration of sheet material being fed and exiting the apparatus by changing the deformation of a constituent wall of the delivery chute shaftway. This wall has a deformable member and displacement devices and holding members which deform the wall's shaftway contours responsive to the density or thickness of the sheet material exiting so as to provide sheet material with a desired contour widthwise.
