METHOD OF BATCHING OF THERMOSETTING MATERIALS WITH FIBROUS FILLER Russian patent published in 1997 - IPC

FIELD: plasticization and batching of thermosetting materials with a fibrous filler at their moulding. SUBSTANCE: inlet chamber, in which batches of the preset mass and temperature are moulded, is rotated at a speed equal to the angular velocity of the plastic material being extruded. Rotation of the inlet chamber at a speed equal to the angular velocity of the plastic material being extruded makes it possible to eliminate the tangential stresses in the plastic material thus preventing mechanical break-down of the fibrous filler. EFFECT: enhanced quality of articles. 2 dwg , 1 tbl
