Automatic rotary arm stretch wrapping machine for palletized loads equipped with waterproof covering by a polyethylene sheet.

Working Principle

Pallet wrapping is obtained by means of the arm rotation combined with the spool carriage vertical slipping along the rotary arm. Seal covering is obtained by two wrapping coils, one upward and one downward. The coils fix on all four sides a polyethylene sheet positioned at the top of the palletised load.

Pre-Stretch Carriage

The electronic pre-stretch carriage allows film stretching up to 300%. The unwinding speed, controlled by a motor installed on the carriage, is inverter-driven and based on load perimeter.

Touchscreen

The touchscreen display allows easy setting of wrapping parameters. In addition, it displays any stoppage causes (self-diagnosis) and production data.
