Process for the manufacture of zip fasteners characterized by the fact that a mechanical organization is constituted preferably by the chain placing of an extrusion machine a high frequency welding machine a punching machine and an automatic shear by means of which the endless production is achieved the zipper closure that is pursued from a tube of plastic material that is made in the aforementioned welding machine is practiced all along its central part a strip of electric welding that divides the original tube into two tubular ducts and then proceeds to the stamped by the punching machine between said strip and the two edges of the tube rectangular punches that when combined with a continuous sinuosidal cut of the one practiced by the same or another punching machine simultaneously form the two elements of crimped teeth that characterize the clasreselemento s that while still assembled, they are cut to a predetermined length as they are forced to circulate through the automatic shear of the said organization.
