A core of rotatable unit for manufacturing a coil of a flexible object and enveloping the coil to form a parcel for delivery to a user of the object. According to the invention the core comprises a number or longitudinal support elements (3) and two flat end rings (1, 2) each with a central opening (6), an inner circular support surface (7) with predetermined radius, and recesses (8) arranged in connection with the support surface (7). The end portions (9, 10) of the support elements are in engagement with the recesses (8) to fix the end rings and support elements to each other. Furthermore, the inner sides (14) of the support elements (3) coincide with the support surfaces (7) of the end rings and the end surfaces (11, 12) with the outer sides (5) of the end rings. A method is also described for manufacturing said coil, commencing with assembling said core.

La présente invention concerne un noyau d'unité rotative destinée à la fabrication d'une bobine d'un objet flexible et à l'emballage de la bobine pour constituer un paquet destiné à l'utilisateur. Selon la présente invention, le noyau comprend un certain nombre d'éléments de soutien longitudinaux (3) et deux anneaux d'extrémités plats (1, 2), chacun pourvu d'une ouverture centrale (6), une surface-support circulaire intérieure (7) ayant un rayon déterminé, et des renfoncements (8) disposés en liaison avec la surface-support (7). Les parties terminales (9, 10) des éléments de soutien sont en prise avec les renfoncements (8) pour fixer les anneaux d'extrémités et les éléments de soutien les uns aux autres. En outre, les faces intérieures (14) des éléments de soutien (3) coïncident avec les surfaces de soutien (7) des anneaux d'extrémités, et les surfaces terminales (11, 12) avec les faces extérieures (5) des anneaux d'extrémités. L'invention concerne aussi un procédé de fabrication de la bobine en question, qui commence par l'assemblage du noyau.
