DEVICE WITH VERTICAL FLOATING MANDREL ASSEMBLY FOR POSITIONING AND CENTERING A THERMOPLASTIQUE SHEATH AROUND OBJECTS

摘要

ABSTRACT OF THE DISCLOSURE A method for mounting and centering of a sheath and / or thermoplastic sleeve around an object in-which use is made of a vertically floating mandrel, held in levitation bearings and provided in its lower hollow portion of a moving part to former Tremite which is fixed for a footprint cover the head of the object Gland. This process is characterized in that the movable part is actuated from the outside, during the descent of the sheath around the mandrel, by solely mechanical means. Implementation AV-operative part of this method according to which the inner movable member to the mandrel and terminating at its base by the fingerprint is mounted on a spring shaft for optionally-view and is provided with first elements disposed in a recess the mandrel capable of cooperating by contact with second actuated elements of the former interior of the mandrel to come into abutment, at predefined pace-terminated on the first elements.
