All the jaws are associated with a single common drive, each driving train includes a slide block operatively connected to this drive and situated on the bisector of the angle made up by two adjacent guideways. The slide block carries a freely rotatable member likewise situated on the bisector of the angle and operatively connected with each jaw of the respective pair.
