Abstract
This pinching-shaping device includes cylindrical tools, each having a central axis of tool rotation, the central axes being parallel and the outer peripheries of the tools applied tangentially against one another to pinch-shape a strand tangentially introduced between the tools during rotation. The outer periphery of each tool has radially projecting blades distributed around the central axis, each providing a pinching surface. The pinching surface extends between first and second ends inclined to the central axis. The blades of each tool are distributed following the outer periphery, alternating inclination. When a blade of the first tool is radially interposed between the two tools during the rotation, it is radially aligned with one of the blades of the second tool, the pinching surface inclined in a complementary manner to the pinching surface of first tool's blade, pinching the strand between pinching surfaces of these two aligned blades.
