Improved clamps for closing envelope packs, of the type constituted by two pivoting arms reatada in two fronts that incorporate the heating means to activate the welding of the corresponding edges of the envelope, characterized essentially because next to the fronts of the jaws are provided floating plates by means of springs, which face each other in their rest position protrude from teeth of the jaws, determining the ejector means of the envelopes with respect to said jaws, which are articulated in a fixed central point and actuated by the central part of the jaws. A swinging arm by means of two connecting rods, the swinging arm being connected to an adjustable connecting rod and provided with telescopic damping, the connecting rod of which is linked to a follower arm of the profile of a rotating cam on a driving axle.
