DI SERRAGGIO SU OGGETTI DA FISSARE. METODO ED APPARATO PER INSTALLARE E FISSARE AUTOMATICAMENTE FASCETTE

摘要

A method and apparatus for carrying out the method in which a clamp made from a flat blank is plastically deformed into circular shape, is locked in its closed condition, is transferred from the deformation station to a transfer station where it is placed over the object to be fastened and is thereafter tightened onto the object. In order to maintain the clamp in predetermined position on the object before being tightened, the clamp is additionally plastically deformed into a slightly non-circular shape differing from the circular shape of the object and is again elastically deformed into its original circular shape before being placed over the object so that return of the clamp to its slightly non-circular configuration will provide sufficient frictional engagement to hold the clamp in predetermined position.
