Title (EN) METHOD FOR FORMING A TUBE ARTICLE ON A CORE
(FR) PROCEDE DE FORMATION D"UN ARTICLE TUBULAIRE SUR UN NOYAU
Abstract: front page image
(EN)A method for forming an elastomeric tube on a core (20) wherein a core (20) is loaded into a vacuum chamber (14, 114) in a vacuum container (10, 110); an elastomeric sheet (36) is placed thereover and sealed around the edge of said container; the core (20) is pressed into the sheet (36) an a vacuum is created in the vacuum chamber (14, 114); the sheet (36) is stitched to the core (20); excess elastomeric material is trimmed away and removed; and the core (20) is turned over with the above steps repeated to form the other side of the tube. The container in which the core (20) is placed may be either moved in a closed path between the tools which perform the steps or it may be stationary with the tools moved to it.
(FR)Procede de formation d"un tube elastomere sur un noyau (20) consistant a charger le noyau (20) dans une chambre a vide (14, 114) dans un conteneur a vide (10, 110); une feuille elastomere (36) est placee par dessus et collee autour du bord de ce conteneur; le noyau (20) est enfonce dans la feuille (36) et un vide est cree dans la chambre a vide (14, 114); la feuille (36) est cousue sur le noyau (20); le materiau elastomere en exces est coupe et enleve; le noyau (20) est retourne et les etapes ci-dessus sont repetees pour former l"autre cote du tube. Le conteneur dans lequel le noyau (20) est place peut etre soit mobile dans un chemin a boucle fermee entre les outils qui effectuent les etapes du procede, soit stationnaire, les outils se deplacant vers lui.
