Abstract
Method and its corresponding apparatus for installing a ring-shaped element in the inner wall of a tube of thermoplastic material along a predetermined section thereof, which method includes operations consisting of: Assembling, on a common axis, side by side, a support element for widening therein a ring-shaped element, and a divided locking element which can be deformed to enlarge or reduce its external diameter, Engaging in said support member a ring-shaped element having an outer diameter greater than the inner diameter of the tube, Widen said blocking element divided with said ring-shaped element at its rear part, Mounting an annular sliding element on said support element on the side opposite said split blocking element and moving the support element in the axial direction to apply the ring-shaped element against the blocking element, Locally heating the tube to soften an area of the tube extending from the extremity to an installation position of the ring-shaped element, Introducing said assembly into said softened zone of the tube, whereby the softened zone widens causing the ring-shaped element mounted in said assembly to pass through the softened zone to the installation position, Locating around the softened zone of the tube, an external molding element having an internal cavity which provides the desired appearance and shape after the installation of the ring-shaped element, Applying said external molding element on said softened and enlarged area of the tube so that the ring-shaped element penetrates the internal wall of the tube, Cooling the tube to hold said ring-shaped element in this state in the tube, and Contracting said divided blocking element to make it marry through said ring-shaped element and separating said assembly and said external molding element from the tube.
