Method and apparatus for transporting signatures around a roll without introducing skew |
摘要 |
An apparatus for transporting folded signatures is provided which includes a first roller and a second roller forming a first nip with the first roller. The first and second rollers each have a compressible outer layer, and are rotatable about respective axes. Preferably, the compressible outer later comprises a microcellular foam. The apparatus also includes a plurality of first transport tapes passing through the first nip and a plurality of second transport tapes passing through the first nip. The plurality of second transport tapes are wrapped at least partially around the second roller so that a signature transported between the first and second transport tapes between the first nip undergoes a change in transport direction as it is transported at least partially around the second roller. Preferably, the signatures enter the first nip perpendicular to a plane passing through the axes of the first and second rollers. |
