摘要

METHOD AND APPARATUS FOR FORMING SINKABLE MASSES, ESPECIALLY A HIGH MOLECULAR FOOT MIX, CHARACTERIZED IN THAT A SINKABLE MASS IS PROVIDED CONTINUOUSLY, IN THE CONDITION IN WHICH IT CAN RUN AND AN OVERPRESSURE, TO AN EXTRUSION DEVICE, IN THAT THE FLOWING MASS IS THEN, AFTER ITS ENTRY INTO AN EXTRUSION CYLINDER 5 AND BEFORE ITS EVACUATION, COOLED, ALSO GOOD FROM THE OUTSIDE, THROUGH FROM THE EXTRUSION CYLINDER 5 THAN FROM THE INSIDE, THROUGH CAVITES 5C, 5D HOUSED IN AN ENDLESS SCREW SHAFT 6, UP TO A TEMPERATURE LESS THAN ITS SOLIDIFICATION TEMPERATURE AND IN WHICH THE MASS THAT IS '' THEN DRAWN AND THE SOLIDIFIED MASS ARE TRANSPORTED BY THE ENDLESS SCREW SHAFT 6 IN THE DIRECTION OF A VENTING LOCATION 9 HOUSEHOLD IN THE EXTRUSION CYLINDER 5.
