ROTARY
DIE-CUTTING solutions

Unlike with flat-bed die-cutters processing sheets, webfed rotary die-cutting solutions allow very high production speeds and extremely fast set-up, offline, for the maximum OEE.

After a high-speed printing stage, the converting of printed materials – including embossing, creasing and cutting operations – usually proves to be slow. It is especially true with flat-bed die-cutters and, in a lesser extent, with sheetfed rotary die-cutters.

Webfed machines allow significantly higher speeds via inline rotary die-cutting (RDC) solutions.

RDC machines combine oustanding cutting precision (without nick points), durability and a production speed up to 3 times as high as flat-bed die-cutters.

When used inline, right after the printing stage, RDC solutions also prevent from any interruption of the production flow.
They therefore generate time and labour savings.

Komori-Chambon expertise

  • 100% design and manufacture

     

    Komori-Chambon offers benches, cassettes and tools.

    Combine them for the best efficiency and ease of use.

    We can assist you as well on selected sections of solutions.

     

  • Quality and durability

     

    Frames, format parts and tools show that there is no compromise on quality.

    Their top-level durability can be further-extended through resharpening and refurbishing.

     

  • True taylormade design

     

    The infinitely variable repeats guarantee the best answer to your needs.

    Push the limits of precision and deliver perfect blanks, without nickpoints.

  • High speed

     

    The cutting stage will no longer be the bottleneck of your production flow.

    Enjoy a record 450 m/mn speed, whatever the cardboard type.

Production flow insights

  • The tools are prepared offline so that the OEE (Overall Equipment Effectiveness) is maximum.
  • Simple and fast settings are proceeded for an instantaneous and stable production quality.
  • Very quick installation of the tools onto the production line.
  • The embossing can be separated or combined with the creasing and cutting stations.
  • It is then the first out of usual 3 stations.
  • An infeed unit regulates the web flow between the printing and the converting stages.
  • A high precision creasing is crucial for an efficient folding and filling process
  • The liquid packaging industry is extremely demanding in terms of accuracy.
  • The bricks must remain perfectly sealed.
  • Komori-Chambon has built a very strong knowledge in inline creasing
  • Perfect cutting at high speed, up to 450 m/mn is allowed by the rotary die-cutter
  • 100% cut or half cut, standard cartonboard or PE coated : the tools are adapted to the substrate (single knife – crush cut or twin knives – scissors cut)
  • The cylinders also follow your versatility targets and ease of operation, from solid (monobloc) to segmented, shell or magnetic types.
  • A sheeting process can be considered thanks to a sheet-cutting tool integrated inline.
  • The stripping stage is key in the customers acceptance and satisfaction
  • To avoid the usual speed loss and jam risks, the design and precision must be high-level
  • Available in inboard or outboard (separated) configuration
  • Available in single blank or multi-blanks versions
  • For maximum versatility, the RDC can include a cross-section cutting function with variable repeat
  • No need to modify the regular installation. The web will by-pass the cutting station and be transfered to the slitter
  • The production can be handled seamlessly whatever the converting operations.

 

RDC Versions

Roll-in Roll-out type

Offering the highest efficiency thanks to the maximum available widths, the Roll-in Roll-out models are also easily transported and installed.

Equipped with wheels, they can be moved along without using a lift truck.

Changeovers are handled very fast.

Cassette type

Transported with a lift truck, these models are extremely stable. Their sliding onto the bench is air-assisted.

Available configurations

INLINE

For an optimized production flow, the rotary die-cutter (RDC) is installed inline.

The RDC can be fitted after a Komori-Chambon printing line or after an OEM equipment.

The inline set-up avoids any flow interruption

OFFLINE

The rotary die-cutter is installed right after the unwinder and is fed by a printed roll.

The embossing, creasing and cutting stages are done (in whole or in part) offline.

A delivery solution can be added downstream.
