Fully Automatic High Speed 2 Lines Bags On Roll Making Machine With Core Changing Device By Servo Motors Control

CW-PR-SV series are special designed high-speed machines which can produce 2 lines, printed or plain bags-on-roll with core, for use as supermarkets vegetables and fruits bags or garbage bags.

Equipped with 6 servo motors, each line can process different type of bags from the other line, at the same time, whether printed or plain bags, different bag length and even different quantity of bags per roll. This difference in production per line is possible as each line have its own 3 independent servo motors, 1 servo motor at main machine for bag length and 2 servo motors at the 2 rewinding stations.

Each line has its own temperature controllers for the UPPER sealing knife and DOWN heated silicon band forstrong seal of the bags even if it is bottom seal for standard flat and gusseted film or star seal for folded film.

More features of the machines are listed below:

  • Special for two lines perforating bottom sealed and star sealed bags on roll with automatic paper core changing system.
  • Fully automatic paper core changing system.
  • In-line triangle folding device for star sealed bags.
  • E.P.C.(Edge Position Control) keeps the film at correct position.
  • Japan made servo motors and servo drivers control bag length precisely, high-speed production, and reducing electric consumption.
  • Bag length, production speed and all parameters can be changed easily from both touch screens of main machine and rewinding unit.
  • German made photocell-SICK for accurate printing mark.
  • Automatic lift up system with air shaft makes film roll change fast, simple and easy job for a single worker.
  • Automatic tension control with AC motor and inverter system for jumbo diameter film roll.
