TRIM AND FILM WASTE PELLETIZING UNIT

The recovery of edge trim on blown film lines has constantly posed many problems due to: • the line speed that varies depending on the trim thickness • the quantity of trim to be recovered in terms of numbers and width • the electrostatic charge of the trim and its regrind that can make it difficult to re-use during extrusion The new RECOTRIM® has been developed specifically to address the above mentioned concerns. This systems design considerations must include an extremely user friendly operation as its incorporation into the production sequence should be seamless in order to facilitate optimum...

Detail of the extrusion die with blade cutting group and cooling system. The air enters from the center of the die as well as from the outside flowing tangentially to the die, reducing to a minimum the chances of the hot pellets accumulating anywhere in the cooling flow stream. The main blower assembly, separated from the primary extrusion unit, is equipped with a noise reducing inlet filter and a spiral device for cooling the pellets. Quick and simple electrical and mechanical connections make it easy to move the machine and locate it to the best possible position for optimum performance.
