Abstract

Girdle for boxes of yarn bobbins, characterized in that it consists of a flexible laminar strip, which essentially has three consecutive parts, separated by fold bands, in which the central part contains at each end a projection with an outer flank perpendicular to the base, while an end part has a cylindrical protuberance, on the same side as said projections, and the remaining end part has an elongated protuberance, also on the same side as those projections, with recess on the opposite side, in an extreme zone, so that said strip is used in collaboration with a cardboard box or the like consisting of a base and two walls parallel to each other, inside which a plurality of spools of thread are placed parallel to each other. Corresponding inner tube, having in said walls circular holes in correspondence with the mouths of that tube, all this so that a box is subject to closure by means of a plurality of strips, as many as spools, applying its central part on the open face of the box, and its end parts in external connection with respect to the walls thereof, for which it is first introduced the elongated protuberance of the strip in a mouth of the tube, laying its recess against the inside face of the wall of the box, while the cylindrical protuberance is applied in the remaining mouth of said tube, while the projections of the part central, together with the adjacent end parts, clamp the front areas of the walls of the box, all of which achieves the enclosing closure of the box with respect to the coils, and the individual retention of the same.
