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.

düspohl Maschinenbau presents its latest RoboWrap development at this year's FRONTALE. This profile wrapping machine, with its completely automatic set-up, already produced on customer order, represents düspohl's new flagship. RoboWrap meets the producer requirements in terms of shorter set-up times with simultaneously smaller lot sizes and reduces these times to only two minutes by employing both modern and tested robot technology.

The necessary input is extremely simple, and is logged by the control software and implemented using an automated process. Three chain bins within robot gripping distance store up to several hundred pressure rollers of varying geometries. A 2D laser scanner measures the individual rollers in a fraction of a second at each pass and stores data on the diameter, contour and position. RoboWrap puts every other conventional solution in the shade, when the total of 19 six-axis robots independently access the optimum pressure rollers and position them on the profile with a repetition accuracy of only 0.03 mm.

This new machine concept comprises automatic positioning systems for all format-dependent machine assemblies, beginning with charging and carrying on to protective film application. Intelligent systems such as the FHS film heating system with contactless temperature monitoring, the film unwinder's diameter-dependent brake force control, the nozzle positioning system and, last but not least, the contactless PrimeStar primer application method with quick-change application heads, round off RoboWrap and make it the world's first profile wrapping machine with completely automatic set-up.

In addition, we also present at our fair booth:
The AutoCut film slitting machine – equipped with automatic slitter positioning, it slits a wide variety of papers and films and produces perfect, ultra-tight winding results.
