ABSTRACT:
A trough structure is provided for bending a web of paper widthwise to provide beam strength and controllability to the web of paper, for aiding in guiding the web of paper in a straight path. The trough structure causes the paper to curl widthwise to conform with the shape of the trough structure. The trough structure comprises a concave or convex lower wall upon which the paper flows, open ends through which the paper flows, and shoulders which attach to both sides of the lower wall and extend substantially horizontally from the sides of the lower wall to symmetrical positions above the lower wall. The shoulders act to contain the paper in the trough structure and guide the paper through the trough structure. A drive roll is provided for driving the paper through the trough structure. No buckling of the paper is caused when any slight misalignment occurs between the paper and the drive roll, and this slight misalignment is self-correcting due to the edge guiding function of the trough structure.
