Overview

The FlexCut delivers finished cut-sheets with a variable cut-off from 203mm (8“) to 711mm (28“) and up to 1828mm (72“) along with the Long-Sheet option. The overall system is designed to enable nonstop operation during a cut-off length change.

The sheeter conveyor system will transport sheets to the stacker and will feature a vacuum hold-down system and overhead belts over the entire length of the sheet to ensure precise copy control. The stacker will employ a tagging system to identify jobs within the stack.

Features:

• Variable Cut-Off from 203mm (8”) to 711mm (28”) or 1828mm (72”)
• Zero Make Ready from Job to Job with different Cut-Off
• Integrated Variable Chip-Out (up to 25mm)
• Edge Trim Removal
• Heavy Paper (up to 350gsm)

Options:

Edge Trim Removal

• Integral shear cut slitting system for edge trim removal. Manual adjustment of knife positions
• Manifolds supplied for edge trim waste and dust collection.
• A vacuum and waste collection system can be supplied optionally in the absence of customer supplied plant central waste collection system.
• Maximum media weight for edge trim is 220 gsm unless heavy paper option is specified.

5up A4 Trimmed Stacks

• Deliver deep pile stacks finished cut and edge trimmed a dedicated A4 size 5 across.
• The solution will include (in addition to required optional edge trim) shear slit knives for gutter removal between lanes.
• include a modular “A4 hopper adapter” for 5-up operation in the stacker.
• Hopper adapter will be easily removable (< 5min) for conversion back full sheet width stacker operation.
• Other sizes dedicated formats (4-up 8.5 x 11 for example), could be alternatively specified.
• Maximum media weight for trimmed stacks is 220 gsm

Long Cut (1850 mm) and Stack

• Knife geometry and servo control are sized to facilitate this cutoff, as well as the conveyor section of the sheeter.
• The stacker functions in a similar manner to that the standard stacker but it’s longer and significant
• changes to the fork interrupt system, overhead sheet assist mechanism, and pallet raise/lower mechanism.
• Stack weight is limited to 3500 lbs. in this version.
• Longer cut-off requirements will handle up to 100” (special request).

Heavy Paper (up to 350 GSM)

• Larger diameters for idler rollers and cylinders will be required, as well as higher capacity slitter components. One scenario is to design/build this section of the machine in a separate (modular) unit upstream of the sheeter to house these heavier components.

Right Angle

• Angle bar for installation of a sheeter solution at 90 degrees to the press.

Rewind / Unwind

• Rewind / Unwind system to allow for maximum production flexibility.

Linear Perforation

• Perforation unit installed prior to the sheeter cylinder.
