Abstract
This self centred expandable shaft is made up of a support tube where double pneumatic pistons are inserted into the centre part creating a tapered shape and having a central passage way that allows pressurized fluid to be pushes during the expansion phase or for the retroaction phase it can flow back and forth and allow the clamping elements to exit out of the opening providing the tubular support section flowing over the surfaces of the pistons in order to supply the radial push for the perfect centring and support of the bobbin with the mechanical system while on the peripheral of the tubular part are provided for the longitudinal recess inside which radially slides the listels continuously in rubber which, put into motion through an air chamber system, allow holding and attaching the bobbins in order to impede them from rotating while in use.<IMAGE>
