The present invention relates to a device for folding a sheet of paper into an aerodynamic configuration. The device can be described as a forming implement with a plurality of wing and tail folding surfaces. The device includes an entrance end and an exit end and is adapted to have a sheet of material passes therethrough. In use, as the sheet of material is passed through the device it attains an aerodynamic configuration. In the preferred embodiment of the present invention, the wing and tail folding surfaces are resiliently mounted to the device. Furthermore, the device includes a means for delivering the sheet of material from the entrance to the exit end of device.
