01 / How It Works

Four precise stages. One continuous line.

Cut sheet laser printers produce folios printed three, four or five booklets to view. The operator feeds each folio at the guillotine, and from there every booklet is cut, stitched, bound and delivered automatically, controlled from a single centralised touchscreen.

  1. Cheksafe hydraulic guillotine module with HMI touchscreen
    01

    Guillotine

    Folios are placed on the registration infeed table. Photocell registration aligns each folio beneath the hydraulic blade, and infeed fingers index it forward cut after cut until every booklet is separated.

  2. Twin Deluxe G20 stitching units with wire spools
    02

    Stitch

    A pneumatic arm transfers each booklet to the reciprocating main track. Deluxe G20 heads insert two stitches 6 mm from the spine, with stitch-detect verification on every book.

  3. Cheksafe tape binding module
    03

    Tape Bind

    Hot-melt tape is formed around the spine in three heated stages: applied to the top surface, folded down the spine, then wiped across the underside for a clean, tamper-evident finish.

  4. Belcon mini output conveyor
    04

    Output

    Completed booklets are delivered onto the output conveyor, ready for final inspection, packaging, or on-line wrapping and enveloping.

03 / Optional Modules

Extend Cheksafe into a complete production cell.

Add verification, wrapping and enveloping on-line, all controlled from the same HMI as a single unified system.

Integrity & Verification

Automate

Replaces manual loading with automatic feeding and collating, then verifies every sheet before stitching for 100% document integrity. Combined with Cheksafe it forms the Cheksure system.

  • Bulk feeder holds approx. 8,000 sheets and can be topped up while running
  • Suction feeder collates at up to 20,000 sheets per hour
  • Mis-feed and double-feed detection, with side and end jogging
  • Bar code (1D/2D), OCR or OMR reading of every sheet, up to A3

On-line Mailing

WM6 Wrapping Module

Wraps finished booklets in a pillow pack with two end seals and a single long seal, giving a fully automatic, space-saving on-line mailing facility.

  • Paper, foil or plastic film, overprinted for opacity if required
  • Registered wraps with transparent address windows
  • Down-stream feeders for inserting extra plain or folded documents
  • Hand-fed stand-alone, or loose or hard coupled in-line

Inserter Integration

On-line Envelopers

Taped books are transferred one at a time onto your inserter, so they go straight into envelopes. A bridging conveyor lets both machines also run independently.
