Abstract

This manufacturing drum (2) comprises: - a barrel (4); - a body (6) mounted on the barrel (4) and having a central portion (8) and two end portions (10) arranged axially on either side of the central portion (8) and having a groove (12) for receiving a pneumatic rod; and - two tubular membranes (14), each covering a groove (12). Each tubular membrane (14) is elastically deformable between: - a first position in which said tubular membrane (14) is generally cylindrical and remains radially distant from a bottom (16) of the groove (12) concerned; and - a second position in which said tubular membrane (14) is deformed and is in contact with the bottom (16) of the groove (12) concerned.
