More information on the Digitax ST - .PDF file.

Mimi, an Italian manufacturer of packaging machinery, has incorporated Digitax ST servo drives from Control Techniques within its latest Mito shrink wrapper, which is designed as an end-of-line machine for the wrapping of different configurations and pack sizes of bottles, cartons, cans or tubs. 

Bottles or other containers are fed into the machine by conveyor and marshalled by a pneumatic separator into blocks of the specified number. 

At this point, a chain driven by a brushless motor conveys the bundle into the wrapping area; the heat-shrinkable plastic film is unwound under controlled tension from a roll and the film is cut from underneath into pre-determined lengths using a rotary cutter mechanism driven by brushless motor. 

The cut edge is drawn forward and held precisely in place by toothed suction belts and it moves into the shrink tunnel, where it shrinks into a secure package, and on to the after-cooler.
