PREDA Cut To Length Line

AML-1-1300 / 1500 / 1600

Basic coil processing line — leveling, beading and shearing to length. Also known as AUTO DUCT LINE 1. The cut to length line is the basic configuration of the PREDA auto duct line family, processing coil from decoiling through leveling and beading to precise shearing to length. Compared with auto duct line 2, it does not include the notching stations — and it can be upgraded to auto duct line 2, 4 or 5 simply by adding further workstations.

Workstations & Functions

  • Electric decoilers (4 sets of rollers) driven by independent frequency controlled motors
  • Multi-functional main body with capability of leveling and beading
  • Mitsubishi computer controlling system and software
  • Mitsubishi and Siemens electric box and electrics
  • Precision shearing to length
