| 摘要 |
The invention concerns a jaw comprising several wedges (6, 7) arranged in angular sectors about a generally cylindrical duct designed to receive the strand such that the wedges are urged to be engaged on the strand between a first zone located towards a jaw front side and a second zone located towards the jaw rear side. Each wedge has at least one portion whereof the thickness, radially measured relative to the duct, gradually increases from the jaw front towards the rear thereof. The wedges are so shaped that the jaw has substantially a rotational symmetry about the duct axis in the first zone and does not have rotational symmetry in the second zone, thereby preventing a wire layer of the strand from forming a shape retaining tube by the clamping effect. |
