PINCE DE MAINTIEN D'UNE MANCHE SOUPLE ET PROCEDE D'OBTURATION PAR SOUDURE DE CELLE-CI

摘要

Heating tongs (6) are used to cut a sleeve (4) fixed around an opening (1) of a chamber (2) after the objects to be taken out of the chamber have been introduced. Another pair of tongs (9) is placed on the side of the opening (1) to tighten the sleeve (4) and to keep it flat to avoid pleats, to allow ventilation during the preparation and to avoid tension in the sleeve; the latter would compromise the sealing taking place.
