1. The remaining segments are internally moulded into a truncated cone.

2. ‘Mâconnais’ is distinguished principally by its characteristic truncated cone shape reminiscent of the plug of a barrel.

3. Moreover, the flow adjustment part (8) has an approximately truncated cone shape provided with a slope section (9) and a flat section (10).

4. View the Cone Instructions below to learn how to manually layout the flat pattern for a truncated Cone in single or multiple gore sections

5. The Coxa is usually a stout, truncated cone of cuticle, freely mobile with respect to the thorax; but in Lepidoptera the middle and hind Coxae are fused to the thorax

6. According to the invention, the webs (5) are formed with retaining surfaces (7) in the shape of a truncated cone shell, which run at an acute angle relative to a longitudinal direction of the expansion anchor from the rear to the front.

7. The invention relates to a thread forming screw (10) for screwing directly into a borehole (12). Said screw (10) is introduced into a solid anchoring base and has a screw head (14) with tool driving means, an essentially cylindrical shaft (16), and preferably a truncated cone-like or a truncated pyramid-like tapered point (18).
