ABSTRACT:
The machine includes a base supportable on a horizontal surface and a framework mounted to the base and supporting thereon three rollers in fixed positions with the axes of the rollers extending parallel to each other and the projection thereof forming a right angle triangle in a plane normal to and traversing the axes. The hypotenuse of the right angle triangle faces downwardly, a first leg of the right angle triangle extends horizontally and a second leg of the right angle triangle extends vertically downwardly from the first leg such that the belt received on the machine has a fixed active upwardly facing horizontal flight extending along the first leg of the right angle triangle and a fixed active vertical flight extending along the second leg of the right angle triangle. A first backup platen is fixed to the framework and positioned beneath the horizontal active flight and a second backup platen is fixed to the framework behind the vertical active flight. A motor is mounted to the machine for rotating the rollers such that the horizontal active flight travels to the vertical flight and the vertical flight travels downwardly from the horizontal flight.
