Na valcovú plochu konfekčného bubna sa podlá technologického predpisu naložia bočnice,kostrové materiály a ostatné komponenty podlá typu vyrábaného plášťa. Privedením vzduchu rozvodom vo vreteni 11 je kužel 310 tlačený smerom ku stredu konfekčného bubna. Cez jeho kuželovú treciu plochu sa prenáša pohyb na segmenty 320 a v nich pevne uchytenú gumovú manžetu 321, ktorá segmenty 320 obopína. Nastáva narastanie pôvodného p D konfekčného bubna na potrebný priemer pre uchytenie v narážači pripravených pätkových lán 50.Súčasne narastá aj priemer bubna cez stredové pásky 410 nad stredovým kruhom 40.Po uchytení lán 60 v polohe x” sa pomocou vodiacej skrutky 10 cez maticu 212.puzdro 211 a unašač 210 zmení otáčavý pohyb vodiacej skrutky 10 na osový pohyb pätkového kotúča 20, ktorý cez valec 30, segmenty 320 a manžetu 521 posunie pevne uchytené laná 60 z polohy x do polohy ”y. Po nabombirovanx polotovarov cez rozvod vo vreteni 11 nasleduje vlastný úkon ovíjania a ohrňovania. Počas jedného zdvihu pákového ramena 50 sa súčasne ovinú ako komponenty okolo lán 60 tak aj prehrnú a pritlačia bočnicu k ramenu plášťa 80 Umožňuje to mechanizmus pákového ramena 50 s ohrňovacimi kladkami 501. otočné uložené v lôžkach puzdra 511 a objímke 512 pevne spojených s držiakom pák 510.Sila potrebná na pritlačenie bočníc je vyvodzovaná pružnými sťahovacími krúžkami 502, ktoré plnia aj funkciu zabezpečenia polohy pákového ramena 50 v základnom stave. Pracovný pohyb pákového ramena 50 zabezpečuje pneumatický valec 520 s tesniacim krúžkom 521 pevne spojený s držiakom pák 510 a piest 550 s piestnym krúžkom 531 pevne spojený s pätkovým kotúčom 20. Zpätný pohyb pákového ramena 50 zabezpečujú zpätné valčeky 543 s piestnou tyčou 542,piestom 540 a piestnym krúžkom 541.Po vykonaní operácie ovíjania a ohrňovania sa vykonajú zostávajúce operácie v oblasti nárazníkov a behúňa, čim je ukončená konfekcia surového plášťa 80.On the cylindrical surface of the ready-made drum according to the technological regulation, the sidewalls, skeletal materials and other components are loaded according to the type of the manufactured jacket. By supplying air through the distribution in the spindle 11, the cone 310 is pushed towards the center of the building drum. Through its tapered friction surface, movement is transmitted to the segments 320 and a rubber collar 321 fixed therein enclosing the segments 320. At the same time, the diameter of the drum also increases through the center strips 410 above the center circle 40. After fixing the ropes 60 in the x-position, the guide screw 10 passes through the nut 212. the housing 211 and the carrier 210 transform the rotational movement of the guide screw 10 into the axial movement of the bead disk 20, which moves the fixed ropes 60 from the x position to the y position through the cylinder 30, the segments 320 and the sleeve 521. The ramming of the blanks through the distribution in the spindle 11 is followed by the actual wrapping and folding operation. During one stroke of the lever arm 50, both the components around the ropes 60 and the folding and pressing sidewall against the arm arm 80 are simultaneously wound. This is enabled by the lever arm mechanism 50 with folding pulleys 501. The force required to press the sidewalls is exerted by the elastic tightening rings 502, which also fulfill the function of securing the position of the lever arm 50 in the ground state. The working movement of the lever arm 50 is provided by the pneumatic cylinder 520 with the sealing ring 521 firmly connected to the lever holder 510 and the piston 550 with the piston ring 531 firmly connected to the shoe disc 20. The return movement of the lever arm 50 is the piston ring 541.After the wrapping and folding operation has been performed, the remaining operations in the area of the bumpers and tread are carried out, thereby completing the assembly of the raw tire 80.
