Abstract
An extrusion device that produces plastic film includes at least two feed units that feed feedstock to an extruder, wherein each feed unit has at least one discharge opening including a discharge closure to open and close the discharge opening, and a container interface that reversibly fastens a discharge container that accommodates feedstock discharged from the respective feed unit.
Claims10
An extrusion device that produces plastic film comprising at least two feed units that feed feedstock to an extruder, wherein each feed unit has at least one discharge opening comprising a discharge closure to open and close the discharge opening, and a container interface that reversibly fastens a discharge container that accommodates feedstock discharged from the respective feed unit, wherein, by the container interface, the discharge container automatically remains in a predetermined discharge position during discharge of the feedstock from the feed unit, wherein the container interface has an upper side and a lower side, and the container interface is attached at the upper side and the lower side is built to receive the discharge container from below.
An extrusion device for producing a plastic film, having at least two feed units for feeding feedstock to an extruder, wherein each feed unit has at least one discharge opening comprising a discharge closure for opening and closing the discharge opening, and a container interface for reversibly fastening a discharge container for accommodating feedstock, which is discharged from the respective feed unit, wherein by the container interface the discharge container automatically remains in the desired discharge position during the discharge of the feedstock from the feed unit, and the discharge opening, at least the discharge closure or the container interface have a sensor device for identifying an occupancy of the container interface so that the discharge process is carried out at every feed unit at which a discharge container is already arranged.
