Abstract

En ekstruder til dosert tilførsel av kunststoff eller kunststoffblandinger til en presseform (14) har en blande-og transportskrue (2), et mellomlager (6) som er koblet etter skruen (2) for pressmasse som er plastifi-sert av denne skrue, hvilket mellomlager (6) har et stempel (6') for i det minste delvis tømming av mellomlageret og en forbindelseskanal (4) fra mellomlageret (6) til pressformen (14). Etter mellomlageret (6) er det koblet en stengeinnretning (8) og i tilslutning til denne er det anordnet en doserings-sylinder (7) som over forbindelseskanalen (4) er forbundet med utløpsmunnstykket (5). Utløpsmunnstykket (5) og/eller forbindelseskanalen (4) kan stenges med en ytterligere stenge'nnretning (9).
