Abstract

Παράγονται διαμορφωνόμενα σε καλούπι αντικείμενα από υδατικό αιώρημα ινώδους υλικού, ειδικά πολτού ινών, δια τοποθετήσεως ενός στρώματος του υλικού μέσω μιας διαδικασίας τοποθετήσεως επί του εξωτερικού μέρους καλουπιού το οποίο σχηματίζει το περίγραμμα το οποίον είναι διαπερατό για να επιτρέπει επίδραση κενού επί του υλικού μέσω του υλικού του καλουπιού. Πριν από την επίδραση αυτή κατασκευάζεται καλούπι το οποίο τουλάχιστο ως προς το μέρος σχηματισμού περιγράμματος του καλουπιού συνίσταται από υλικό σωματιδίων λίθου του οποίου τα σωματίδια συνδέονται ομού για τη δημιουργία μιας κατασκευής με ένα σταθερής μορφής εξωτερικό περίγραμμα με διόδους διαμπερείς αέρα προς το εξωτερικό μέρος του καλουπιού. Η τοποθέτηση διεξάγεται ακολούθως επί του κατά τον τρόπο αυτόν δημιουργηθέντος καλουπιού. ωMolded articles are produced from an aqueous suspension of fibrous material, especially fiber pulp, by placing a layer of the material through a casting process on the exterior of the mold which forms the contour which is permeable to allow a vacuum to be applied to the material through the material of the mould. Prior to this effect, a mold is constructed which, at least in the contouring portion of the mold, consists of a stone particle material whose particles are bonded together to form a structure with a fixed outer contour with air passages to the outside of the mold . The placement is then carried out on the mold created in this way. oh
