TRACTION GROUPS FOR EDGE TRIMS
Single and twin traction groups are fitted to standard TRIA granulators for both small and large outputs. The cutting geometry and rotor of the granulator is adjustable to continually accept edge trim feed, regardless of the material type or thickness. TRIA calculates the size of the granulator from the number of edge trims to be fed, taking into account the maximum line speed, thickness and material types in order to ensure the granulator is properly sized and will meet both your short- and long-term production needs.
The in-feed rollers are designed to eliminate the possibility of material slippage by being either smooth or scored to suit the application. Turn key systems are supplied for full integration with the extruder speed and to ensure the trims remain under constant tension. Evacuation systems to a central area or a closed loop design are also available. A standard traction group may be be suitable for film edge trim recovery or, for thin film, the popular bypass system is recommended as shown in the Traction Group Brochure below.
