Abstract:
Yarn-winding metal reel which comprises an annular series of electrically welded modular elements (1), with each element (1) composed of a single rod having a plurality of bends therein featuring:a first parallel pair of identical long arches (1a), each long arch having a free end; a first parallel pair of identical radial arms (1b) directed towards a center hub (4) of the reel and connected to the two arches (1a) by means of a connection step (1c); a second parallel pair of identical short arches (1d), concentric with respect to a peripheral first parallel pair of identical long arches (1a) and facing an opposite direction from the long arches with respect to the parallel pair of identical radial arms (1b); a second parallel pair of identical radial arms (1e) directed towards the periphery of the reel and shorter than the first parallel pair of identical radial arms (1b) and terminating in respective ends; a transversal bar (3) connecting the respective ends of the second pair of identical radial arms (1e), the modular elements (1) being disposed adjacent to one another forming the reel such that the transversal bar (3) of each modular element (1) contacts an intermediate section of the first parallel pair of identical radial arms (1b) of the adjacent modular elements, being electrically welded thereto, and such that the free ends of the first parallel pair of identical long arches (1a) of each modular element (1) contact the connection steps (1c) of the adjacent modular element on the periphery of the reel, being electrically welded thereto wherein each modular element is connected to each adjacent modular element by two welds.
