One of the SISTEL’s commitments is its pledge and dedicated efforts to R&D+i activities. SISTEL promotes this commitment and in this sense carries out R&D+i actions and projects related with innovation and optimization of sheet metal working industrial processes by equipping installations with state-of-the-art Automation and Control Solutions. In this section we outline some of the most outstanding projects carried out always in collaboration with our customers.



First Level Supervision System Software.
The supervision system will be realized with the software package Scada WinCC 7 of Siemens and will represent graphically every single part of the installation afield, with alarms, reports, maintenance procedures, and the possibility of command. The workstation supervision PC has no management functionality but only of supervision and has the purpose of speeding up the identification of any problem by the engineers and maintainers. The lack of functioning of this system does not constitute any lack of functionality of the installation.

Second Level Software.
For the traceability of each coil will be provided a software developed in Visual Studio 2008 (in particular in C#). This software will be linked to the production through the OPC Server of Simatic NET and will record the production datas of each coil on SQL Server 2005 Standard Edition. For the OPC client will be used a standard library Advosol, Professional Edition source version. Similarly will be linked by IBM WebSphere MQ Services 6.0 to an AS400 to provide/receive datas.

Moreover will be of use as server to any client that will require the visualization of both actual and historical datas. In fact it will also developed a client interface that will connect to the server by remoting technology and soap protocol. It will be also entrusted to display the datas in graphic format and to generate the appropriate report. The datas backup on DVD will be made on the server side (including database modeling).


  • Database with wear and tear control of the blades on the two sides and statistics for rectification.
  • Loading of the blades at warehouse from the translators roundabout with automatic formations.
  • Supervision of the warehouse for the individuation of the positions and the quantity of the blades  and loading/unloading.
  • Manufacturing orders in sequence of delivery priority with possibility of  transformation of the priorities or of the availability of blades in the warehouse.
  • Composition of the formation with automatic selection of the rubbers and of the blades in function of the characteristics of the manufactured material.
  • Composition of the cutting program automatically acquired or for specific requirements and manual insertion.
  • Automatic composition of the formation for specific requirements with manual insertion or with elimination of any toolmaker.
  • Composition with definition of the space between the blades symmetric or differentiated.
  • Simulation of the formation in function of the manufacturing order.
  • The assembled heads ready for the manufacturing.
  • Cutting program Archives for future reutilize with possibility of printing.
  • The assembled heads ready for the manufacturing.
  • Upload of the formation at the warehouse.
  • Load and unload in the machine.


The entire formation of blades, gums and outdistancers after the machine manufacturing is sent by way of the loading turntable to the washing machine that in five stages cleans it without decomposing it.

Osmosis Square, plant for the purification of the water of loading and reintegration:
The reverse osmosis is a process of separation of foreign bodies from water by means of the use of semi-permeable membrane. These are structures that permit the passing of water but keep the mineral melt elements, the colloids and the bacteria.

Jets tank pre-warming/management:
The formation is submitted to pre-warming and preliminary degreasing by means of jets under pressure of the (cleansing/protective) process solution coming from the exertion tank.

Degreasing activated by ultrasounds:
The autoclave is filled with the solution coming from the tank placed with aspiration in depression and the materials subjected to the action of ultrasounds at high intensity for the programmed time.

Rinse with jet:
The materials are invested by jets of ultra-filtered solution.

For avoiding an under-cooling of the autoclave and of the contained materials because of the evaporation of the adherent solution, the autoclave is warmed by strips inside that the warm solution go through. Intercepted the penetrations, the autoclave is evacuated by a specific pomp. The extraction of the incondensables and of the steam of water is interspaced by periodical fluxes with air coming from apposite valve openings. The materials, dried in this way, result protected by the residual film of the washing solution. The aspirated air/steam mixture is condensed on a refrigerated changer before the admission in the environment.


Why & When install the MultiDrives System.

Extremely compact drives series, the MultiDrives System, offers an array of benefits to integrators, OEMs, panel builders and end users who are optimizing energy usage through precise control of Motors. Since drives are available both in MultiDrives and single drive configurations, it is useful to define the difference and profile the benefits that the next generation of MultiDrives now provides to users. A single Industrial Drive is used in any application in which there is mechanical equipment powered by motors; the drive provide extremely precise electrical motor control, so that motor speeds can be ramped up and down, and maintained, at the speed required; doing so it utilizes only the energy required, rather than having a motor run at constant (fixed) speed and utilizing an excess of energy. Since motors consume a majority of the energy produced, the control of motors, based on demands of loads, increases in importance, as energy supplied become ever more strained. Additionally, end users of motors can realize 25% to 70% energy savings via use of Motor Controllers (Despite these benefits, the majority of motors continue to be operated without drives). Single industrial drives are highly flexible AC drives that can be customized to meet the precise needs of a single-motor application. These units convert AC power to DC, and then invert the DC back to an AC output to a motor. These MultiDrives cover a wide range of powers and voltages; single industrial drives also feature a wide range of built-in options as standard equipment. They can be installed for most applications right out of the box and they also can be ordered and manufactured as a customized unit for a particular application. 

What is a MultiDrives System.

A MultiDrives is built from industrial drive modules that are connected to a common DC bus bar. The common bus bar is used to supply the drive modules with DC power, and each module then inverts the DC to AC and powers an individual motor. The DC power is derived from a single supply unit (rectifier) that is built into the front end of the same MultiDrives configuration. This construction simplifies the total installation and results in many benefits: savings in cabling; reduced line currents and simpler braking arrangements; energy distribution over the common DC bus bar, which can be used for motor-to-motor braking without the need for a braking chopper or a regenerative supply unit; reduced component counts; increased reliability; space savings; and there is no need for a separate Motor Control Center (MCC).

Where MultiDrives System can be used.

In general terms, the MultiDrives System can be used whenever several drives/motors form part of a single or integrated mechanical process. The common supply of the MultiDrives enables the implementation of overall safety and control functions, and permits the close coordination of individual drive motors. For example a machine with many motors that must be individually controlled as a complete system. The MultiDrives System offers fast communication of torque and speed signals between the drives, to control the tension in the sheet web. MultiDrives also can be used where the shafts of the individual drive motors are not tightly coupled; for example, in processes where each drive module can be programmed with a speed profile so that the overall use of the energy is minimized. These two examples merely demonstrate the range of applications where the Multidrives System offer substantial benefits over other types of drive contractions.
