LESKO RLS

LESKO RLS is a dedicated slitter rewinder to work with both: printed and clean materials. It is perfectly suited for:

• labels confectioning for specified number of labels or roll length

• web slitting

• inspection and making amendments (appending missing labels or removal of faulty pieces)

on die-cut or printed parts of the material. By using our machine, you can easily rewind the various materials including foils thanks to servo motors installed on a rewinder.

TECHNICAL DATA:

control:

• microprocessor control
• panels with a simple and intuitive interface
• control panel with touchscreen + operator panel near the web-connecting table

motors:

• asynchronous motor - the main drive
• asynchronous motor - rewinder(s) drive
• powder brake on the unwinder
• powder clutch on a rewinder

optional:

• servo motor on rewinder:
  • very precise tension control
  • rewinding materials with specific parameters, eg. foils
  • rewinding rolls to Ø 600 mm
• servo motor on unwinder:
  • active compensation of tension during acceleration and braking

sensors:

• current meters and labels electronic counter  
• luminal sensor
• five-line missing labels control system
• ultrasonic sensor of end of the roll with automatic stop

optional:

• US sensor for transparent labels
• sensor for detecting the flags

UNWINDER:

• electromagnetic (powder) brake

optional:

• special spindle with transport rollers for easy loading of heavy rolls
• US sensor provides a uniform web tension during the whole production

WEB-CONNECTING TABLE:

• equipped with pneumatic clamp blocks, thanks to which the tension of the material is retained during webs connection

WEB MOTION:

• BST web guide system with smooth control

NIP-ROLL:

• pneumatic clamp
