| 摘要 |
The invention pertains to a hopper loader apparatus for separating and forming an overlapping shingled stream of individual signatures of sheet materials from a vertically aligned, parallelepiped shaped stack of such signatures (18) for subsequent handling operations. The hopper-loader has a chassis (12); a first continuous, downwardly inclined planar conveyor (16) mounted on the chassis (12) which moves a stack of vertically aligned signatures and deposits them onto a second conveyor (20) as a separated, shingled stream of the signatures. The second conveyor (20) is mounted on the chassis (12) and aligned with an end of the first conveyor (16). It has a plurality of driven belts which travel over each of an upwardly inclined planar ramp segment (24), an arched transition segment (26), and a planar exit segment (28). The arched transition segment (26) comprises either a belt slide or a plurality of serially arranged rollers (30). <IMAGE> |
