Abstract

Procédé et appareil permettant de former un fond à une extrémité ouverte d'un tube sans matériau d'apport. On forme un fond dans un tube ouvert aux extrémités en chauffant ce tube et son mandrin de support et en faisant glisser un manchon sur l'extrémité du tube qui, après chauffage, s'évase vers l'extérieur, de manière à rabattre l'extrémité évasée. On ferme l'extrémité rabattue du tube en la mettant en contact avec un moule coopérant avec le manchon pour façonner le fond. Application particulière à la fermeture sans matériau d'apport de tubes en matière thermoplastique.A method and apparatus for forming a bottom at an open end of a tube without filler material. A bottom is formed in a tube open at the ends by heating this tube and its support mandrel and by sliding a sleeve over the end of the tube which, after heating, flares outwards, so as to fold back the tube. flared end. The folded end of the tube is closed by bringing it into contact with a mold cooperating with the sleeve to shape the bottom. Particular application to the closure without filler material of tubes of thermoplastic material.
