Abstract

IMPROVEMENTS IN THE MANUFACTURE OF PROFILES-ZIPPER, characterized essentially by the fact that the closed section profile, preferably rectangular, will have on its two smaller sides three protruding outward ribs arranged longitudinally and perpendicularly to them, and parallel to each other, which are continued in the same arrangement on the inside of the profile, but with less prominence, forming two channels separated from each other by the central nerve, which are provided along their entire length with a series of perforations in the form of small elongated windows, which serve to house in them pieces, moths or supports finished in rectangular appendices of the same profile and size of the small windows having in its lower part a slot to be inserted by hooking in the lower parts thereof; this rack profile has on its other two sides which are the larger ones of grooves centered parallel and located equidistantly from each of the angles or corners of the profile that penetrate towards the interior in a semi-tail arrangement of a dovetail; for this reason, they have, as an addressable element in them and complementary, another profile consisting of a prolonged plane, towards one of its sides, at both ends perpendicularly by a narrow band which in turn extends outwards through trapezoidal projections , which together have the same shape as the above-mentioned grooves made in the larger sides of the rack-and-side profile and which are attached and penetrate them, this plane being prolonged towards the opposite side by two others parallel to each other which are perpendicular to it and which form a channel of considerable depth between them.
