UNITECH T012 AUTOMATIC PRE-STRETCH REWINDING MACHINE
Unitech T012 is an automatic rewinding machine to produce pre-stretched and conventional film rolls with core.
The automatic rewinder mod. T012, works at the average speed of 1.100 m/min; this speed may be adjusted depending on the quality and the thickness of stretch film, up to a maximum speed of 1.200 m/min.
The rewinding process is made on a station complete with automatic loading of the core, cut of the stretch film and exit of the rewinded roll on a powered device positioned at the outfeed.
Pre-stretch ratio can be adjusted on the HMI, then elaborated from the PLC controlling the machine, to allow a fine adjustment of the relationship between the pre-stretch rollers. The maximum elongation (till the breaking point of the elastic memory is reached) will depend on the stretch film being used.
The machine can rewind film without pre-stretching it.
All servo motors (brushless) are controlled by servo drives, with linked communication via fiber optics; this system allows to have the maximum control of the motors and of the stretching tension.
The HMI (touch screen) and all the control devices (such as pressure regulators) are installed on the structure of the machine for an easy and immediate use.
