Sheet reversing apparatus for a copier/finisher system

In an electrostatographic reproduction system having a document handling apparatus for advancing individual document sheets from a sequenced or collated stack to an exposure station and return to the stack in repeated cycles, an electrostatographic processor including an image fixing device for processing copy sheets having a path of movement during which the copy sheets are processed, the improvement comprising:

• an apparatus for producing attached sets of copy sheets,
• means for transporting copy sheets to a position whereat sheets are collected for attachment by a fixing element by said apparatus for producing attached sets, the transporting being effected along a double curved path to a path of movement approximately 180.degree. from the path of movement of the sheets through the processor,
• a turn-around mechanism for directing the copy sheets from the image fixing device and the path of movement through the processor to the path of movement to said apparatus for producing attached sets, said turn-around mechanism having a plurality of rotating circular members arranged in at least two successive sets to which the copy sheets are applied after images thereon are fixed by the fixing device for conveying the same through said curved path, said members having relatively large diameters for minimizing deformation thereof and being positioned vertically above the image fixing device.
