A manufacturing process for filler tube includes: a workpiece arrangement step of arranging a workpiece onto an outer peripheral mold not only to axially lock a to-be-locked portion with respect to a locking portion but also so as to make the outer peripheral mold, which is set at a predetermined temperature, support a cylinder-shaped body of the workpiece on the outer peripheral face; and a flare-molding step of flare molding a flange by inserting an inner peripheral mold, which is set at a higher temperature than the predetermined temperature of the outer peripheral mold, into a to-be-molded portion on the inner peripheral side, and by relatively moving the outer peripheral mold and the inner peripheral mold in the axial direction to make a counter-welding-face forming portion and a welding-face forming portion clamp the to-be-molded portion between them in the axial direction.

Device for fixing a connection to an OPW airbag, with an expansion sleeve (2), with a plurality of expansion shells (4), and a mandrel (6) extending longitudinally through the expansion sleeve (2) having a stretching piece (8) arranged in the vicinity of the expansion shells (4), the outer diameter of which stretching piece is greater than the inner diameter of the expansion shells (4).

In a first aspect, the current invention concerns a method for fabricating an intrauterine device (IUD), said method comprising the step of providing a coaxial rod comprising an outer polymeric layer and a polymeric core, and further comprising the step of cutting from said rod at least one rod segment having a predetermined length, whereby, simultaneously to cutting said rod segment from said rod, the rod end portions thereby formed are compressed into dome-shaped end portions, in such a way that, at said dome-shaped end portions, said polymeric core is at least partly enclosed by said outer polymeric layer. In a second aspect, the current invention concerns a device for cutting a rod segment from a rod.

A method for securing a fitting 14 to a composite material rod 12, the method comprising forming a bore 20 in an end part of the rod 12, inserting a tool 26 into the bore 20 to cause radial expansion of the end part of the rod 12, inserting a retainer 22 into the expanded end part of the rod 12, and withdrawing the tool 26 from the end part of the rod 12, the retainer 22 serving to retain the end part of the rod 12 in an expanded condition. An assembly of a fitting 14 and composite material rod 12 is also described.

Method for manufacturing a fluid dispenser. In a finished state, the fluid dispenser has a fluid store and a delivery opening through which fluid is discharged to the environment in a delivery direction. The fluid dispenser has a housing component through which the delivery opening is made and which has a delivery structure forming the delivery opening and/or adjoining the delivery opening, for influencing a delivery characteristic. This housing component having the delivery opening is manufactured firstly by manufacturing a base body by plastic injection moulding in a casting mold and then, in a region of a provisional delivery structure of the base body, a mechanical force is applied to deform the provisional delivery structure and hence create a definitive delivery structure.

A composite tube may include a body having a longitudinal centerline axis and an end portion having a tapered section and an end rim. At least one of a radially outward edge and a radially inward edge of the end rim may be non-circular. The end rim may be circumferentially continuous, and the tapered section may diverge radially outward in a direction from the body to the end rim. A joint assembly may include a support wedge that at least partially engages at least one of a radially inward surface of the end portion and a radially outward surface of the end portion of the composite tube.

Various improved designs for expansion tool heads are disclosed herein that are structured (1) to provide improved and more-evenly distributed strain in the pipe during the expansion strokes of the tool head which can include more gradually inducing the strain in the pipe and/or (2) to avoid the induction of plastic deformation of the pipe in regions of seal formation between the radial-inwardly facing surface of the pipe and the radially-outward facing surface of the fittings (i.e., the ribs of the fitting) especially in instances in which the tool head is not rotated between separate expansion steps. This may be achieved, for example, by the use of convexly curved outer profiles that limit initial insertion depth of the tool in the pipe prior to expansions and/or by the use of a hybrid toothed profile.
