Claims12
A pin extruder, comprising:
- a screw conveyor configured to convey plastics, the screw conveyor having a plurality of pins each arranged in a respective pin row, the pin rows being arranged in a plurality of consecutive planes in a conveying direction of the screw conveyor,
- wherein a distance between the planes of at least individual pin rows varies in the conveying direction.
A pin extruder, comprising:
- a screw conveyor configured to convey plastics, the screw conveyor having a plurality of pins each arranged in a respective pin row, the pin rows being arranged in a plurality of consecutive planes in a conveying direction of the screw conveyor,
- wherein at least one pin in a first pin row in a first plane has a smaller cross-sectional surface area than at least one pin in a second pin row a shorter distance from an outlet in a second plane located behind the first plane in the conveying direction.
A pin extruder, comprising:
- a screw conveyor configured to convey plastics, the screw conveyor having a plurality of pins each arranged in a respective pin row, the pin rows being arranged in a plurality of consecutive planes in a conveying direction of the screw conveyor,
- wherein at least individual pins pass through a respective associated gap in flights of the screw conveyor one after the other when the screw conveyor rotates.
