Abstract
In a tensioning gripper with a ring and a coaxially arranged rotary pin, both the ring and the pin are provided with a slot suitable for receiving a matrix to be tensioned. The slot of the rotary pin has a symmetry plane parallel to the longitudinal axis of the rotary pin. The sides of the slot are composed by two angled portions which are arranged symmetrically on both sides of the symmetry plane and both portions converge towards the longitudinal axis of the rotary pin, the two vertices of the portions being opposite and adjacent one another. Such a slot allows easy introduction and gripping of the matrix until, by rotating the pin, the matrix is held and tensioned.
