(only on Master 110) Carriage with double pre-stretching system that can be activated from control panel. The carriage is fitted with a pre-stretching system fixed at 250%. By activating the “Stretch control”, the carriage can automatically switch to activate the stretch variable of electromagnetic clutch positioned on the first roll of stretch. (with QLS system “QUICK LOAD SYSTEM” for easy and quick film loading).
The relationship between gear wheels and the numbers of teeth determines the difference of speed between slow roller and the faster, then the pre-stretch ratio.
Example: with a pre-stretch ratio of 200% the machine can wrap products using only one coil instead of three coils in the case of machine without stretching.
