Abstract

έθοδος δια την εξώθησιν μιας συνθέσεως διογκωσιουπλαστικού υλικού πρός τον σκοπόν επιτεύξεως προφιλε με εσωτερικήν υφήν αφρώδη, άκαμπτον, ημιάκαμπτον ή μαλακή, τα οποία ουρουσιάζουν μιαν σταθεράς εξωτερικήν διατομήν και τα οποία δυνανται να έχουν μιαν λείαν επιφανειαν, δι' εξωθήσεως της ρηθείσης συνθέσεως διογκωσιμου πλαστικού υλικού είς κατάστασιν ατελώς διογκωμένης δια μέσου μιας φιλιέρας χαρακτηριζομένη έκ του ότι εξωθείται το ρηθέν υλικόν δια μέσου ενός τμήαμτος της φιλιέρας του οποίου η διατομή είναι αισθητώς η ίδια πρός εκείνην του επιθημητού προιφλέ, δια διευθετήσεως ενός κοιου χώρουείς το εσωτερικόν του εξωθουμένου υλικού διά μέσου της φιλιέρας. A method for extruding a composition of expandable molding material for the purpose of achievement is profiled with an inner texture of foam, rigid, semi-rigid or soft, having a fixed outer cross-section and having a smooth outer surface, with a smooth outer surface, in a state of inflated through a die characterized in that said material is extruded through a portion of the die whose cross-section is substantially the same as that of the desired profile, by arranging a common space inside the extruder through the extruder .
