摘要： A method and apparatus for making a collar to the end of a pipe. The apparatus comprises an attachment clamp surrounding the pipe and a body part, connected by hinging to a pivoting cradle having a forming cone, which can enter the end of the pipe. In the method, the forming cone is moved axially and obliquely to the central axis of the pipe, inside the pipe until it contacts the inner surface of the pipe, the forming cone being loaded with the desired load pressure against the inner surface. The forming cone is then pivoted using a pivoting cradle outwards from the central axis of the pipe, around the inner edge of the attachment clamp, and the forming cone and pipe are simultaneously rotated with respect to each other around the central axis of the pipe until the desired collar has formed.
