Yakatwasuka seam simbi pombi inoramba ichikunguruka maitiro, iyo inoenderera ichitenderedza maitiro inoshandiswa mukuenderera mberi kwekukunguruka uye dhayamita yekudzikisa maitiro epombi yesimbi. Continuous simbi pombi kukungurutswa inzira iyo pombi yesimbi uye core rod zvinofamba pamwechete mumastand akawanda. Iyo deformation uye kufamba kwepombi yesimbi inobatwa panguva imwechete nemupumburu uye core rod.

Iyo mandrel inogona kunge yakasununguka-inoyerera, ndiko kuti, inofambiswa nesimbi kuti ienderere mberi; inogonawo kuganhurirwa, ndiko kuti, kupa mandrel kukurumidza kwekufamba kudzikamisa kufamba kwayo kwemahara. Munguva yekufamba, iyo mandrel, roll uye simbi pombi yakabatanidzwa mune yakazara, uye chero shanduko mumubatanidzwa ichaita kuti mamiriro ehurongwa hwese achinje. Dzidziso yekuenderera mberi kwekukunguruka ndeyekudzidza hukama huri pakati pavo.
