Abstract

Aparatul si procedeul pentru realizarea unui bleder pentru formarea portiunilor de talon si flanc ale unei anvelope pneumatice, conform inventiei este utilizat la confectionarea anvelopelor pneumatice radiale, cuprinde niste suprafese de vulcanizaredin care suprafata exterioara formeaza o cavitate inelara de sectiune în forma de V în care patrunde o insertie de vulcanizare creînd un spatiu egal cu dimensiunea finala a blederului pentru rabatarea si întoarcerea pliurilor unei carcase de anvelopa pneumatica. Procedeul, conform inventiei consta în obtinerea unui bleder rabatabil pentru rabatarea si înfasurarea pliurilor unei carcase a anvelopei pneumatice si consta în asezarea blederului neprelucrat într-o forma de vulcanizare cu cavitate inelara cu o sectiune transversala în forma de V apoi înainte de aranjarea finala a bleiderului se introduce o instalasie în interiorul cavitatii inelare în forma de V astfel încît........
