  • - The CLEVER SLOTTER changes the old concept of a slotting length predetermined by the slotting sleeve diametre.
  • - It’s equipped with 5 parallel lines of tools, each moved by its own brushless motor: 2 lines for slotting sleeves, 1 line for creasing sleeves, 1 line for pre-creasing sleeves, 1 line for tab-cutting and trimming knife.
  • -The CLEVER SLOTTER operating speed is regulated by encoders to continuously adapt it to the production line’s operating speed, be it brand new or outdated.
  • - The slittings are made without changing knives mounted on sleeves: it can slot both on the front and rear side, with slot lengths from 0 to 600mm with a single slotter head and up to 1100mm with two in-line slotter heads without ever having to rearrange the knives.
  • - Can work cardboard thicknesses from 2.5mm to 13mm.
  • - Slotting width of 10mm, with an optional for 8mm.
  • - Belt transmission using profiled pulleys that don’t need lubrication.
  • - A robotized head controls the position of the equipment.
  • - Slotters and creasers can have a minimum distance between each others of 32mm. Model sizes range from a width of 2500mm to 5500mm, but each size is able to work minimum sheet widths of 460mm, with each short side measuring a minimum of 30mm and each long side measuring a minimum of 180mm. Sheet height can range from 270mm up to 3000mm.
  • - Each program can be memorized by the machine in less than a minute.
  • - The setup of the memorized program happens separately from the line of work, without delaying it, and only lasts a few seconds.
  • - Allows the movement of slotting and slitting tools along the whole width of the machine: for example, the tab-cutting can be done on the left or on the right or on both sides. This means being able to perform a double work in one go.
  • - Tools positioned with extreme precision ±0,1mm.
  • - Its main use is with Bizzozero’s Boxmaster, but it can be paired with any sheet working line.

  • The Clever Slotter is made on demand from 2500 to 5500 mm wide. The Clever Slotter, made for BIZZOZERO lines from 2500 to 3300, can be also put in line with all types of Flexo Printer Slotter or Casemaker of any width, new or already in production making it more profitable and more automatic in order to reduce the time of set-up.
