Abstract

CE PROCEDE DE MOULAGE PAR COMPRESSION CONSISTE: A REALISER DEUX EBAUCHES, DONT LA FORME CORRESPOND A LA REPARTITION DE MATIERE DE L'ENVELOPPE AUTOUR DU CORPS; A POSITIONNER L'UNE DESDITES EBAUCHES AU SEIN DE L'EMPREIENTE FEMELLE(14) D'UNE UNITE DE MOULAGE INFERIEURE (11), LADITE EMPREINTE CORRESPONDANT A LA FORME A CONFERER A L'ENVELOPPE; A POSITIONNER AU DESSUS DE LADITE UNITE INFERIEURE DU MOULE AINSI MUNI DE L'EBOUCHE, UNE PLAQUE OU GRILLE INTERMEDIAIRE (19), DEFINISSANT EN VOLUME LA FORME EXTERNE DU CORPS OU DE PARTIE DE CELUI-CI, AU NIVEAU DE SES DEUX FACES PRINCIPALES; A POSITIONNER SUR LA FACE, SUPERIEURE DE LA GRILLE AU NIVEU DU VOLUME OU SAILIE LA SECODE DESDITES EBAUCHES; A FERMER LE MOULE, LADITE UNITE SUPERIEURE DE CELUI-CI ETANT EGALEMENT MUNIE D'UNE ENPREINTE FEMELLE (16), ET CE PENDANT UNE DUREE SUFFISANTE POUR INDUIRE LA REALISATION DE DEUX DEMI-COQUES, DESTINEES A CONSTITUER EN FINAL L'ENVELOPPE EXTERNE DU CORPS; A OUVRIR LE MOULE ET A RETIRER LA PLAQUE OU GRILLE INTERMEDIAIRE; A POSITIONNER AU NIVEAU DE L'EMPREINTE INFERIEURE DE L'UNITE INFERIEURE DU MOULE A CORPS, LADITE EMPREINTE INFERIEURE ETANT MUNIE DE LA DEMI-COQUE INFERIEURE, FAISANT ALORS FONCTION D'ORGANE DE CENTRAGE DU CORPS; A REFERMER LE MOULE PENDANT LA DUREE NECESSAIRE A LA RETICULATION OU VULCANISATION DE L'ENVELOPPE ET COROLLAIREMENT, A LA JONCTION DES DEUX DEMI-COQUES REALISEES LORS DE LA PRECEDENTE FERMETURE DU MOULE, AFIN D'ABOUTIR A UNE ENVELOPPE CONTINUE; A OUVRIR LE MOULE EN FIN DE RETICULATION OU VULCANISATION, PUIS A RETIRER LE CORPS ALORS MUNIE TOTALEMENT OU PARTIELLEMENT DE L'ENVELOPPE EXTERNE(5).THIS COMPRESSION MOLDING PROCESS CONSISTS OF: MAKING TWO BLANKS, THE FORM OF WHICH CORRESPOND TO THE DISTRIBUTION OF MATERIAL OF THE ENVELOPE AROUND THE BODY; TO POSITION ONE OF SAID BLANKS WITHIN THE FEMALE FOOTPRINT (14) OF A LOWER MOLDING UNIT (11), SAID FOOTPRINT CORRESPONDING TO THE SHAPE TO BE CONFERRED ON THE ENVELOPE; TO BE POSITIONED ABOVE SUCH A LOWER MOLD UNIT AND PROVIDED WITH THE MOUTHPIECE, AN INTERMEDIATE PLATE OR GRID (19), DEFINING IN VOLUME THE EXTERNAL SHAPE OF THE BODY OR PART OF IT, AT THE LEVEL OF ITS TWO MAIN FACES; TO POSITION ON THE FACE, UPPER OF THE GRID AT THE LEVEL OF THE VOLUME OR SURROUNDING THE SECODE OF THE SAID BLANK; TO CLOSE THE MOLD, SAID SUPERIOR UNIT THEREOF ALSO PROVIDED WITH A FEMALE PRINT (16), AND DURING SUFFICIENT DURATION TO INDUCE THE PRODUCTION OF TWO HALF SHELLS, INTENDED TO CONSTITUTE THE EXTERNAL ENVELOPE OF THE BODY; TO OPEN THE MOLD AND TO REMOVE THE INTERMEDIATE PLATE OR GRID; TO BE POSITIONED AT THE LEVEL OF THE LOWER FOOTPRINT OF THE LOWER BODY MOLD UNIT, SAID LOWER FOOTPRINT BEING PROVIDED WITH THE LOWER HALF-SHELL, WHICH FUNCTION AS A BODY CENTERING MEMBER; TO CLOSE THE MOLD DURING THE DURATION NECESSARY FOR THE CROSS-LINKING OR VULCANIZATION OF THE ENVELOPE AND CORROLLARY, AT THE JOINT OF THE TWO HALF SHELLS MADE DURING THE PREVIOUS CLOSING OF THE MOLD, IN ORDER TO PROVIDE A CONTINUOUS ENVELOPE; TO OPEN THE MOLD AT THE END OF CROSS-LINKING OR VULCANIZATION, THEN TO REMOVE THE BODY THEN TOTALLY OR PARTIALLY PROVIDED WITH THE OUTER SHELL (5).
