  • Description


    The GUK SA30/SA52 Accumulator Folder can fold single sheets—or, fold together sets of 2 to 8 pre-collated sheets together in a single cycle. It can be adapted to receive collated sheets from digital presses, super copiers (like the DocutechTM) collators, sheeters, and web presses—when certain specifications are met. 

    Simple operation...

    • Setup and changeovers are quick with zero-makeready plates and caliper-set folding rollers.
    • The folding system includes a batch counter and a sheet accumulator unit.
    • The accumulator unit receives and accumulates the number of pre-collated sheets as entered in the batch counter and then advances the set to the folding section to be folded together.


    • With an optional OMR (optical mark reader) or bar code reader, the system can be programed to fold varied pre-determined sets.
    • When switching to jobs with similar specifications (e.g., fold pattern, sheet length, etc.), adjustments to the folding system may not be necessary, depending on the paper weight and number of sheets.
      accumulated according to the number set on the batch counter, then folded together.
    • The system can be run independently by equipping it with a flat-pile feeder as shown above.

    High productivity…

    • Depending on the stock, it will letter-fold 5,800 to 6,200 sets of two to five 8 1/2" x 11" (A4) sheets per hour.
    • The accumulator folding system comes in two sizes: SA30 with an 11-3/4" (300 mm) format, and SA50 with a 19-1/2" (500 mm) format

    Easy to set up:

    • Zero-makeready plates that are set up to fold or deflect with a turn of a dial.
    • Rollers setup by inserting thicknesses of paper in caliper devices.



    Accumulator Unit:

    • Receives and accumulates pre-collated sheets according to the specified number before sending them to the folding unit.
  • Feeder


    FL2 Flat-Pile Feeder

    • Feeds sheets up to 33-3/8" (80 cm) in length. Its maximum pile height is 25-1/2" (65 cm).
    • Suction heads lift the sheets at the REAR SEPARATING FEED SYSTEM. Air blasts aerate and separate the sheets making it possible to feed long difficult-to-handle sheets.
    • A DRUM SUCTION INFEED WHEEL, shielded by a safety cover, transfers the paper onto the registration table toward the folding rollers.
    • A quick caliper-set double-sheet detector ensures accurate feeding.
    • The rear separator is hinged to lift up and out of the way for easy loading.
