The new AutoCut with an automatic positioning system for disc knives.Any team leader would be proud to call the latest generation of AutoCut-type reel slitter-winders their own. This equipment is a dream come true, especially in terms of the reduction of set-up times and hazard potentials. düspohl now supplies the machine with an automatic positioning system for disc knives. The upper and lower knives are pushed onto the knife shaft by a positioning unit. The required cutting widths are defined by the user on a touch screen.

The required number of cutting tools are taken from a bin and aligned with a precision of +/- 0.1 mm. This only takes a few seconds per knife. In addition, the positions of the upper and lower knives can be independently programmed. In this way it is possible to position an available lower knife from the opposite side close to an upper knife in order to support the material being cut, for example. www.duespohl.com

düspohl Excellent winding quality!

Among other things, 2 ultrasound sensors ensure excellent quality of the wound reels. These permanently measure the material reels, both for unwinding and winding, and control the drive and the electric magnetic powder brakes accordingly as a function of the reel diameter. In this way the ideal web tension is constantly maintained and perfect, ultra-tight winding results are achieved in conjunction with the high drive power. Reel slitting and winding machines are used in many industry sectors. For slitting papers and foils of PVC, PP, PE, PU, sandwich foils, laminates, some textiles, metal foils and edge materials of veneer, ABS, melamine resin and other materials.

Five minutes of set-up time in the wrapping zone, as required by RoboWrap, require an adequate solution for the primer application system. Also when working with a classic wrapping machine, 20 seconds of exchanging the application head leave more time for production than 30 minutes of preparing felt strips.

Next to the RoboWrap we will present PrimeStar ECOplus, the ideal application system for VOC-reduced, NEP as well as completely pyrrolidone-free primers in the plastics processing industry. The achieved peel values ​​are process-reliable, permanently repeatable and correspond to the current RAL-GZ 716.

Regarding the complexity of the profile geometries, there are no restrictions.

At Frontale 2020, we will present the new reel changing system ReelWizard by düspohl for the first time. ReelWizard enables you to wrap each profile with a different foil without any interruption of the ongoing production process.

The new system has been developed especially for the pvc industry. It makes sure that the connecting juncture will always be placed between two profiles. This way, the new solution helps you to eliminate foil loss due to reel change. Especially considering the trend towards smaller batch sizes, this gain of flexibility will increase your competitiveness significantly.

Convince yourself and watch ReelWizard in action at Frontale 2020.

This year we will show the further developed version of the RoboWrap, the highlight of profile wrapping. It is the first fully automatic profile wrapping machine which deserves this name.

Once the positions of the pressure rollers have been programmed by the operator, the system repeats the settings fully automatically at any later time. Regardless of how different or similar the previous profile was, the set-up time of incredible 5 minutes is not exceeded! This not only leads to a significant increase in production, but also to greater calculation security in the pricing of our customers. Since the now very intelligent software analyzes the operator's procedure before each set-up process, it always comes to the desired wrapping result even with worn or modified pressure rollers.

Additionally, RoboWrap reduces the production of waste parts to a minimum, no matter how much experience the user has. After the first 1,5 m immediately after production start, it already produces sellable goods.

UniMelt is compatible with all common adhesive application systems: slot coaters, doctor blades and adhesive rollers. It works with PUR and EVA hot melt glues. Both adhesive blocks from 2 - 20 kg or granulates can be used with UniMelt. His major advantages are the continuous melting without interruption of production when refilling and the 100% use of the glue that has been filled in.

Thanks to the special shape and the non-stick-coating, residues can be removed off easily. The melting capacity is automatically adjusted to the production‘s needs. A language-independent touch-screen assures easy programming.
