SC6-II Cutter:

Purpose
The purpose of the CS6-II is to cut a continuous paper web into sheets using a rotary single or double cut cylinders (with chip out). It can handle a variety papers, ranging from lightweight newsprint to card stock. The cutter can be used with most digital continuous printers, as well as offline with an unwinder. Its capabilities extend from 1-up to 4 up production.
On-Line from Printer
Off-Line from Roll

Method of operation
The paper web, arriving from the pre-processing module, is fed in by the pinless infeed roller to the cutting cylinder which cuts the paper web using a rotary knife. Directly after the cutting process, the sheets are conveyed to the post processing module by a sheet outfeed mechanism. The post-processing module can be almost any type of equipment such as a stacker, buckle folder, or shingle delivery.
Chip out: The CS6-II cutter is capable of cutting a chip out of the web. The chip out length is set electronically. Chip out mode can be activated, or deactivated via the panel to handle any kind of pre printed or blank paper.
Blank sheets caused by the printer’s start-up procedure can be automatically diverted using the integrated dynamic diverter and are not passed on to the post-processing module. Any sheets cut during the set-up procedure are also automatically ejected by the diverter.
Document control (e.g. offsetting, stack separation) is controlled by either a counter, separation marks, barcodes, or markless.

Basic equipment

• Basic module with two rotary high-performance shear type cutting cylinders
• User-friendly touch screen machine terminal for set-up and basic operating functions
• Casing with safety monitoring

LS6 Stacker:

Purpose
The LS6 stacker collects sheets and passes the finished stacks over to the post processing. Stack separation and stack offset are done non-stop (without printerstops).

Method of operation
Sheets, arriving from the pre-processing module, are transported on the stacking table using vacuum belts which allow very careful handling of the sheets avoiding any damage of the printed image. Stack separation is accomplished without printer stops in shortest time. The dynamic CS6 cutter interrupts the sheet stream for less than a second to allow the LS6 stacker to insert a new stacking table for the next stack. Afterwards, stacks are ejected on to the conveyor belt.
The LS6 stacker can handle 1-up to 4-up sheet streams delivered by the SE6 separation, alignment and offset module.

Basic equipment

• Basic module with vacuum belt sheet transport and stacking device
• User-friendly touch screen machine terminal for set-up and basic operating functions
• Casing with safety monitoring

SE6 Separator:

Purpose
The SE6 module integrates three different functions in one module:
A) Sheet offsetting on the fly (OOF) without any loss of performance
B) sheet alignment for optimum stack quality in the LS6 stacking module
C) Lateral sheet separation allows offset stacking
The module can handle 1-up up to 4-up sheet streams, depending on the module configuration

Method of operation
The sheet streams from the CS6 cutting module are aligned, separated and offset, while the sheets run through the SE6 module.
None of the SE6 functions limits the performance of the line in any way.

Basic equipment

• Basic module
• Casing with safety monitoring

UW6 Unwinder:

Purpose
Continuous supply of non-impact printers off the roll over a period of several hours.

Method of operation
By pressing a switch the roll with the mandrel inserted is brought into the working position by the motor-driven mechanism. After the paper-web has been pulled in manually, initialization of the module takes place automatically. The roll is driven at the center. The unwinding speed follows the requirements of the printer, under electronic control. The paper rolls can be unwound in either direction of rotation.

Basic equipment

• Unwinding support-frame with electro-mechanical roll insertion
• Operator interface with touch screen
• Adjustable photocell for detecting minimum roll diameter
• Fully automatic danc
