Twin-roller extruder Lekos is designed based on specific recipe.
Hopper is equipped with sensor of mass level for automatic feeding of mass from mixer into extruder. Turns of both rollers can be synchronized electronically. Rollers and hopper can be heated but also cooled, to ensure suitable surface temperature for forming of wide spectrum of masses. Fluent change of speed and thickness of moulded carpet is certainty.
Following equalising roller or rollers ensure concretion of formed carpet on the conveyor belt and achievement of required product height. Even equalising roller can be heated or cooled. It has always own water system which is independent from water system for extruding rollers.
Forming head can be installed in front of entrance to cooling tunnel, to pre-form desired shape on top of bar.
