Exemple de la réalisation de l'invention La vis-mère 10 se trouvant à l'intérieur de la broche 11, munie d'un disque de pied 20; toutefois le disque de pied est lié à l'entraîneur 210, composé d'une douille 211 et d'un écrou. Dans la partie médiane, il y a un anneau central , fixé sur la broche 11, au-dessus duquel il y a une ceinture centrale 410 dépassant au-dessus du cylindre 30. Le cylindre  Brief statement of the drawing The invention is explained in more detail using the attached plan, where below the central axis is presented, in section, the basic condition of the construction drum with its various components , by marking position "X" for laying the foot cables; above the central axis is presented, in section, the position of the semi-finished products of the convex tire, after the winding, the rolling up and the tightening of the flanges, while the position "Y" presents the fixing of the cables foot. Example of carrying out the invention The lead screw 10 located inside the spindle 11, provided with a foot disc 20; however, the foot disc is linked to the driver 210, composed of a socket 211 and a nut. In the middle part, there is a central ring, fixed on the pin 11, above which there is a central belt 410 protruding above the cylinder 30. The cylinder

est muni d'un cône 310 à segment 320 et d'un collet 321.  has a cone 310 with segment 320 and a collar 321.

Au disque de pied 20, par un entraîneur 210, est fixé le bras de levier 50, muni d'une poulie de retroussement 501 et de deux bagues de serrage flexibles 502. Le bras de levier 50 se situe en travers du porte levier 510 et du manchon 511, relié à la broche 11. Au manchon 511 est fixé le cylindre pneumatique 520 muni d'une bague de joint, d'un piston 530, 540 et d'anneaux de piston 531, 541. Dans le piston 540, se trouve la tige de  To the foot disc 20, by a drive 210, is fixed the lever arm 50, provided with a roll-up pulley 501 and two flexible clamping rings 502. The lever arm 50 is located across the lever holder 510 and of the sleeve 511, connected to the pin 11. To the sleeve 511 is fixed the pneumatic cylinder 520 provided with a seal ring, a piston 530, 540 and piston rings 531, 541. In the piston 540, is find the rod

piston 542 pour un rouleau rétroactif 543.  piston 542 for a retroactive roller 543.

Selon la technologie, sur la surface de cylindre du tambour de confection, sont posés les flasques, les matériaux de carcasse et les autres composants, selon le type du pneu fabriqué. Par l'air amené par la distribution dans la broche 11, le cône 310 est poussé vers le milieu du tambour de confection. Par sa surface conique de frottement se transfère le mouvement sur les segments 320 et sur le collet en gomme  Depending on the technology, the flanges, carcass materials and other components are placed on the cylinder surface of the construction drum, depending on the type of tire produced. By the air supplied by the distribution in the spindle 11, the cone 310 is pushed towards the middle of the construction drum. By its conical surface of friction transfers the movement on the segments 320 and on the rubber collar

dessus de l'anneau central 40. Après avoir les câbles fixés 60 dans la position "X", à l'aide d'une vis-mère 10 à travers l'écrou 212, la douille 211 et l'entraîneur 210, le mouvement rotatif de la vis-mère 10 se transforme en mouvement axial du disque de pied 20, qui, à travers le cylindre 30, les segments 320 et le collet 321, fait avancer les câbles bien fixés 60 de la position "X" à la position "Y". Après les semiproduits bombés à travers la distribution dans la broche 11, commence l'opération d'enroulement et de retroussement. Pendant la montée du bras de levier 50, les composants sont en même temps enroulés autour des câbles 60 et le flasque est replié et serré au bras du pneu 80. Cela est permis par le mécanisme du bras de levier 50, aux poulies 501 de retroussement, disposées rotativement dans les lits de la douille 511 et dans le manchon 512, liés fermement avec le porte levier 510. La force nécessaire pour serrer les flasques est déduite des bagues de serrage flexibles 502, qui ont pour fonction d'assurer la position du bras de levier 50 dans la position de base. Le mouvement de travail du bras de levier 50 est assuré par le cylindre pneumatique 520 et la bague de joint 521, solidement liée au porte levier 510, le piston 530 de l'anneau de piston 531 étant solidement lié au disque de pied 20. Le mouvement rétrograde du bras de levier 50 est assuré par des rouleaux rétroactifs 543 avec la tige de piston 542, le piston 540 et  above the central ring 40. After having the cables fixed 60 in the "X" position, using a lead screw 10 through the nut 212, the sleeve 211 and the driver 210, the movement the rotary screw 10 turns into an axial movement of the foot disc 20, which, through the cylinder 30, the segments 320 and the collar 321, advances the well-fixed cables 60 from position "X" to position "Y". After the semiproducts curved through the distribution in spindle 11, the winding and rolling-up operation begins. During the rise of the lever arm 50, the components are at the same time wound around the cables 60 and the flange is folded and tightened to the arm of the tire 80. This is allowed by the mechanism of the lever arm 50, to the pulleys 501 of rolling up , rotatably arranged in the beds of the socket 511 and in the sleeve 512, firmly linked with the lever holder 510. The force necessary to tighten the flanges is deduced from the flexible clamping rings 502, which have the function of ensuring the position of the lever arm 50 in the basic position. The working movement of the lever arm 50 is ensured by the pneumatic cylinder 520 and the seal ring 521, firmly connected to the lever holder 510, the piston 530 of the piston ring 531 being firmly connected to the foot disc 20. The retrograde movement of the lever arm 50 is ensured by retroactive rollers 543 with the piston rod 542, the piston 540 and
