发明名称	A DEVICE FOR PRODUCING A GRATE CONSTRUCTION AND A GRATE CONSTRUCTION
摘要	Η εφεύρεσις αυτή αφορά μίαν συσκευήν δια την παραγωγήν δομών εσχάρας. Γενικώς τοιαύται συσκευαί κατασκευάζονται δια των χειρών με σύνδεσιν εγκαρσίων πλευρών με επιμήκη μέσα υποστηρίξεως δια θερμοσυγκολλήσεως. Δομαί εσχάρας δύνανται να κατασκευασθούν αυτομάτως εις μίαν μόνην βαθμίδα δια μιας διατάξεως εξωθήσεως γνωστής από τας τεχνικάς μεθόδους κατασκευής σωλήνων. Μήτραι σκληρύνσεως δια ψύξεως (1, 2) κινούμεναι προς την κατεύθυνσιν της παραγωγής μετατρέπονται τοιουτοτρόπως κατά τρόπον ώστε αι μήτραι σκληρύνσεως δια ψύξεως να περιλαμβάνουν τουλάχιστον δύο χώρους καλουπώματος (14) συγκοινωνούντας ο εις με τον άλλον μέσω αγωγών (16). ω
