Abstract: A cylindrical workpiece (20) is mounted onto and connected to a mandrel (14) that is itself mounted for rotation about a vertical axis (12). A first end portion of the workpiece (20) is housed within the mandrel (14). A second end portion-projects axially outwardly beyond a radial forming surface (60) on the mandrel (14). A first forming roller (30) is mounted on a swing post (52) that is positioned by an adjustable length strut (56). The strut (56) is elongated to swing the post (52) downwardly and place the roller (30) inside the second end portion of-the workpiece (20). Then, a lead screw (28) is used for pulling on a base (50) that supports the post (52). This pulls a convex face portion (32) of the roller (30) against the inside of the second end portion of the workpiece (20). Lead screw operation moves the roller (30), causing it to stretch the second end portion of the workpiece (20) and move it up onto and then move it radially outwardly along the forming surface (60).

Abstract: A joint of a soft tube comprises a tube joint, an inner sleeve, and an outer sleeve. The inner sleeve is inserted into the soft tube and then the soft tube is inserted into the outer sleeve; then the connecting end of the tube joint is inserted into the soft tube. Next, by a hand tool clamping the actuating ring to rotate the tube joint, the connecting end of the tube joint is screwed into the inner threaded hole of the inner sleeve. The connecting end will cause the section of the inner sleeve having slots to expand outwards. As a result, the corresponding wall of the soft tube will expand and thereby deform so as to tightly resist against the enlarged end of the outer sleeve. Thereby, radial and axially connecting forces are formed, the soft tube can be firmly and tightly secured to the tube joint.
