Zusammenfassung:The invention relates to conveyor belts with steel cord insert, with protection against accidental tearing, which are comprised by the high capacity conveyors in the mining industry. According to the invention, the process consists in introducing flexible zinc- or brass-plated steel strands having the diameter of 1.5 ... 3.2 mm, having applied thereon a 1 ... 2 mm thick self-adhesive rubber layer of the same composition as the carcass, into the coveyer belt structure during the carcass calendering stage, perpendicular to the longitudinal axis of the carcass, the strands being mechanically or manually cut at lengths equal to the distance between the first and last steel cable of the metal carcass. Invenţia se referă la un procedeu pentru realizarea benzilor de transport cu inserţie din cord oţel, cu protecţie împotriva sfâşierilor accidentale, care intră în componenţa transportoarelor de mare capacitate, din industria minieră. Procedeul conform invenţiei constă în introducerea în structura benzii transportoare, în faza de calandrare a carcasei, perpendicular pe axa longitudinală a acesteia, a unor toroane flexibile din oţel, zincate sau alămite, având diametrul de 1,5...3,2 mm, pe care este depus un strat de cauciuc autoaderent, cu grosimea de 1...2 mm şi având aceeaşi compoziţie ca şi cel din care este confecţionată carcasa, toroanele fiind debitate mecanic sau manual, la lungimi egale cu distanţa dintre primul şi ultimul cablu de oţel, al carcasei metalice.
