The Cyclop 20 line of pelletizing units – manufactured by Exact, located in Ciserano-Zingonia (Bergamo, Italy) for recovery of EVA film edgetrims – features a full cold-processing system to ensure that trims (thickness 450-550 microns) are converted into pellets without exceeding limit temperatures that would cause alteration of the properties of the material.
The machines maintain tension in the edgetrim as it exits the extrusion line by means of a pulley system which is synchronised with the extrusion speed by an analogue signal and a correction dancer roller. A conveyor system then feeds the trim into diamond-tip pressure rollers which can be adjusted to suit different film thicknesses and lengths.
