SM SCORE-PERF-SLIT UNITS

For smooth flat folds and clean precise scores, perforations, and slits.

A - Features

The QUICK-RELEASE SHAFTS are easy to set up and install.

 

TWO SETS OF SHAFTS are shown in this overview of the SM50. The inset shows one shaft is fitted with micro perforating (1) and scoring (2) tools—in which case the processes will be performed simultaneously.

B - Features

CALIPER-SET DEVICES automatically set the pressure of the shaft sets. Micro-dial adjustments can be made if necessary.

 


• A clear SAFETY COVER with an electronic interlocking switch ensures safe operation without obstructing the view of operation.

C - Features

Spiral-toothed, hardened, and ground steel helical gears in the synchronous roller drive are slip-free for handling even heavy-weight stock.

• The gear system is located on the exterior (behind safety covers) for easy access.

 

C2 - Features

• The gear system is located on the exterior (behind safety covers) for easy access.
• All GUK SM Score-Perf-Slit Units are available with hydraulic height-adjustable bases, so the alignment tables can be incorporated with a number of GUK folders and direct mail producing systems or other brand digital presses, stitchers, or related primary machines.
• SM Score-Perf-Slit Units handle paper weights from 30 lb. offset to 110 lb. cover.
• Machine speeds are up to 650 ft./min. or 40,000 letter-size sheets/hr.

D - Features

FL2 FLAT-PILE FEEDER
• Suction heads in the REAR SEPARATOR (1) lift the sheets with the aid of air blasts while a DRUM SUCTION WHEEL (2), shielded by a safety cover, transfers the sheets to the register table.

 

D2 - Features

• 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.


• The stacking height is 251/ 2" (650 mm).

E - Features

CONTROL PANEL for programming jobs—setting up the feeder, production speed, sheet length, gap, vacuum, and sheet suction.

 

F - Features

The MCS-106 CONTROLLER for monitoring total, batch and running counts.

 

  • Description

    Description

    A perfect print job can be ruined with folds that crack or are not accurately positioned. For smooth, flat folds and clean, clear scores and slits—properly placed—install a GUK SM50, SM54, SM70 or SM74 Score-Perf-Slit Unit. The units are small in size, so they are the ideal solution for improving the quality of production.

     

    Customize to suit your requirements…

  • Feeder Options

    Feeder Options

    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.

    FL3 Flat-Pile Feeder

    • Feeds sheets up to 40-7/8" (104 cm) in length. Its maximum pile height is 27-1/2" (70 cm).
    • REAR SUCTION HEADS lift sheets with the aid of air blasts while the drum suction wheel transfers the paper to the antistatic alignment table leading to the folding rollers. 
    • Setup and operation is through a touchscreen L4 Controller (1).

    SAF Bottom Suction Feeder

    • CONTINUOUS-LOAD SAF FEEDER has air channels in the side rails for separating sheets to aid the bottom-suction drum in moving the paper to the antistatic stainless steel register table.
