Automatic slitting system with knife holder PSGs-DF from DIENES.

Retrofit – Turning old into new

As a developer and manufacturer of high-quality circular and straight  knives, pneumatic knife holders, as well as fully automatic and manual cutting systems, DIENES supports its customers in continuously improving their production performance. And this with new systems as well as with modernizations of existing machines. Always have your finger on the pulse with Retrofit.

By retrofit, we mean that we turn existing cutting systems into new, future-oriented machines through experienced technical upgrades. This means that we make proven systems even better in the areas of drive, control, automation, production, IT integration, as well as user-friendliness and safety. The systems then work more efficiently and faster, have longer service lives, and do so with more flexibility, cleaner cuts, and less dust. Thanks to our in-house development and production, we can optimally adapt this special retrofit service to the specific requirements and circumstances of our customers.

The process of modernization

1. Technical test

2. Comprehensive advice

3. Step by step automation

The first step is a thorough examination of the existing plant and its technical details, such as speed or minimum cutting widths.

This is followed by detailed consultations, test phases and analyses. In this way, potentials in terms of productivity and quality can be identified through modernization measures.

The last step is the implementation of the discussed modernization. Thanks to the modular design, this can be implemented step by step according to the customer’s needs.

Modernizations in the paper industry

One of the most important steps for successful survival on the paper market is for companies to continuously modernize their plants. For this purpose, we offer both economically efficient standard solutions as well as custom-tailored special optimizations specifically adapted to their areas of application. Our slitting systems with circular and straight knives, for sheeters/equipment (up to 1,000 g/m²), bobbin slitters, narrow and large winders/support and backup rolls (up to 3,100 m/min) are available as ready-to-plug-in systems for retrofitting or completely harmoniously integrated by our specialists at your site. Especially when it comes to low cutting dust development and clean cutting edges, our solutions show their strengths.

Every company has different machinery, every type of material different requirements: Together with you, we discuss your requirements as well as the potential for improvement and find the best solution for each customer individually.

Your advantages

  • Old equipment does not have to be replaced by a new purchase
  • Capital for new investments is saved, thus liquidity is maintained
  • Existing systems integrated into the corporate workflow can thus be continued
  • Improved productivity – for example through higher cutting performance and less dust generation
  • Manual systems can be converted into semi-automatic or (fully) automatic systems
  • If desired, the currently required cutting widths can be taken over directly – from previous cutting recipes or “in-time” from data provided by the production planning department.
  • Significantly shorter set-up times with higher accuracy
  • No or only little re-training / re-acclimatisation of employees
  • Repair costs and downtimes are reduced
  • Often lower electricity costs thanks to higher energy efficiency of the improved system
  • Structural changes to the production area not necessary for new plants
  • Operating technology is easily brought up to date

The right knife holders are essential for a precise cutting result. They hold and guide the knives and can be set and adjusted to achieve the desired result. The correct setting, quality and design of the cutting tools are crucial for the optimal cutting process.
