1. A device for levelling and separating floor tiles, comprising:
a body, with a “T” profile, provided with a supporting base for the tiles to be levelled and a separator element perpendicular to the supporting base, linked to said supporting base by pre-weakened break points, and the separator element being provided with a square window; and
a levelling wedge configured to be inserted into the square window in the separator element and comprising: a lower surface for support on the tiles to be levelled; an upper surface for thrusting the separator element in an upward direction, provided with a plurality of transversal teeth;
a rear surface, and lateral surfaces;
wherein the teeth have an upper profile with a curvature, in a transversal direction, defining therein:
a higher central region, configured to provide a sector for initial contact of the teeth upper profile with a central part of a straight upper edge of the square window in the separator element during a frontal insertion of the levelling wedge into the square window in the separator element;
laterally descending sectors on both sides of this the higher central region configured for progressive contact with lateral parts that are more remote from the central part of the straight upper edge of said square window during a further insertion of the levelling wedge into the square window in the separator element; and
chamfered lateral ends, converging towards an upper area of the levelling wedge and ending at the respective ends of said laterally descending sectors.
