Leonardo 380-530

Request informationinfo_outline

The automatic no stop turret rewinder “Leonardo” is the ideal machine to rewind adhesive labels and no adhesive materials rolls ensuring high performance, increased productivity and ease of use without loosing in the quality of the end rolls that the market requires.

It can rewind cores of all ID from 20 to 76 mm, and allows you to rewind finished rolls up to 350mm external diameter. The job changes are settled from the operator panel, and they are quick and easy (5 minutes!) thanks to the only mechanical adjustment needed: the changing of the shafts.

Leonardo has reached high standards of productivity and leading technology and it is built in two versions:

  • with a so called “hidden” glue that leaves no residue in the material;
  • without glue, a patented system that does not use any glue.

The closing of the rolls through labels, neutral or printed for the transcription of variable data, standard in the without glue model, can be as well supplied in the glue model, to permit a double chance to the customer according with the orders he got. The starting and the closing of the lines to the cores is handled automatically by the machine. The rewinding of the rolls is electronically controlled by brushless motors, ensuring high precision to the band tension and movement, and providing desired management capabilities of the tension.

Leonardo is equipped with a touch-screen panel that allows you to easily set the parameters of the machine with a user-friendly interface. It can be connected to any machine, printing and not, with a speed detection managed by an encoder. It can be equipped with manual, semi-automatic or fully automatic cores loaders, depending on your needs.

Paper width: 380mm and 530mm. Leonardo is the most popular and best-selling machine of our company, simple, efficient and extremely productive.
Practical to set and with a continuous monitoring of the production process.
