IMPROVEMENTS IN THE MANUFACTURE OF AUTOMATIC CLOSURE VALVES FOR PLASTIC BAGS WITH REVIRED BELTS OR SIDES, characterized by that, they are obtained from a flattened tube in which the ends have been twisted towards each opposite side of the tube to give rise to the formation of lateral bellows not centered, with respect to the folds of said tube and on the end of one of these revolving bellows is placed a piece of plastic material which is shaped as a stub at the end of the preparation of the bag, with the aforementioned A spindle located towards the inside or towards the outside of the bag and serving in both cases the inlet of the product in the bag and the automatic closing valve when the product presses towards said filling mouth.
