Method and apparatus of conveying a sheet in a turning action to alter its path of movement. The operator has the option of conveying the sheet through a bump turn mode or a flow turn mode. In the bump turn mode, the original sheet leading edge on a first conveyor is not the leading edge on the second conveyor but instead the sheet side edge becomes the leading edge. In the flow turn mode, the operator can drive the conveyor members of the first conveyor so that the sheet is rotated ninety degrees on the first conveyor and is then deposited onto the second conveyor so that the sheet leading edge on the first conveyor is also the leading edge on the second conveyor. The apparatus consists of a first conveyor and a second conveyor with the first conveyor having individually driven members for the optional modes mentioned. |
