ABSTRACT:
Sheets, such as business forms, are turned so that their orientation is changed from landscape to portrait mode, or vice versa. Simple apparatus effects sheet rotation, and includes a conveyance surface on which a sheet travels in a first direction, first and second rollers for engaging the sheet traveling on the conveyance surface, and first and second drives (e.g., D.C. stepper motors) for driving the first and second rollers independently of each other. A sensor senses the position of the sheet just downstream of the rollers, and a controller (computer)--in response to the sensor--controls the speed and direction of rotation of the motors so that one roller rotates with a given tangential speed in a first direction of rotation, while the other roller rotates at that same speed in an opposite direction of rotation.
