Key Features

Improve Your Efficiency

• Automatic knife/blade positioning
  ensures quick and precise knife setting
• Automatic laser core guiding
  enables precise and very quick core setting for new jobs. The system uses data from the automatic knife positioning system
• Shaft-less unwinding
  Shaft-less hydraulic tilting arms ensure easy parent roll handling
• Splicing table
  A vacuum splicing table with two pneumatic holders and back-light desk enables easy and precise web splicing
• Unloading mechanism
  delivers the finished slit rolls to a rotary stand. The stand rotates in a horizontal or vertical direction.
• Recipe system
  different working parameters are stored in the memory such as speed, tension, lay-on pressure, knife / blade setting and laser core guiding position information
• Automatic cross slitting
  cuts the web of the slit rolls during job changeover.
• Strip holders automatically hold the web in place and maintain the tension in slit strips during job changeover.

Be Sure You Slit With the Best Quality

• Slitting techniques 
  A variable knife shaft permits tangential slitting with lower and upper rotary knives or with razor blades against grooved segment. For more difficult thin substrates it is possible to choose wrap around female knife slitting with rotary knives or with razor blades. It is also possible to combine rotary knives slitting and edge trimming via special additional razor blades.
• Sophisticated tension control 
  The Tenzomat II tension control system enables precise unwind and rewind tension control during the whole operating cycle in a closed loop and therefore slit very thin and difficult substrates.
• Servo drives 
  The system includes 4 servo motors. First motor drives main drive roller, lay-on rollers, knife shafts and banana roller. An unwind AC servo motor in combination with a dance roller control tension of parent roll. The third and the fourth AC servomotor drives both rewind shafts on every single carousel.
• Banana roller 
  An adjustable angle, driven banana roller with hard grooved segments is positioned before the lower knife shaft.
• Eccentric roller An adjustable angle eccentric roller ensures web laying on the lower knife shaft during slitting of wrinkled material.
• Angle adjustable roller 
  An adjustable guiding roller laterally balances the web and contributes to higher quality output during slitting from conical or low quality parent rolls.
• Lay-on rollers 
  Lay-on rubber rollers on tilting arms are fixed on a rod with spring-loaded segments ensuring perfect contact between lay-on roller and finished reel.
• Minimum gap winding 
  This rewinding technique is used to eliminate pressure of the lay-on rollers to the slit rolls. This type of rewinding is usually used for processing materials such as pressure sensitive, self adhesive, cold seal and special structures.
• Torgue rewidning 
  Torque rewinding with pneumatic expanding shafts is an alternative solution to friction ring rewinding and may be used for very narrow slit rolls of paper, when higher tension is need and so on.

Operate With Comfort and Safety

• Overhead web path 
  design suitable for pharmaceutical and food packaging where stringent hygiene and clean room standards are in force.
• Intuitive control 
  Several panels help to operate the machine: 2 touch screen panels for rewinding and slitting, one panel in unwind section with portable control panel for parent roll loading.
• CE standards 
  Machines comply with and meet stringent European safety standards and codes.
• Turreting support system 
  The unique design of the rotary support arms for each rewinding shaft during change-over permits heavy reels to be handled without the risk of overloading the rewind shafts.
• Safety features 
  Machines are designed with maximum emphasis on operator safety. All rotating elements in the slitting section are secured by safety covers and are inaccessible to the operator during the operating cycle. The rewind area is secured by a laser scanner.
