Claims (6)

1. Förfarande för tillverkning av en tili hela sin vtteryta lagringsduglig, förvulkaniserad slitytering, -ringdel eller -segment, som pä dem i förhällande tili slitytan mittemot belägna undersidan har en i pressformen samtidigt tillsammans med själva slityteskiktet tillverkad och häftduglig hAllen, tili konstruktionen valbar skrubbyta och vars övre sida har en slityteprofil, kännetecknat därav, att pä den i pressformen pä den i förhällande tili slitytan mittemot belägna undersidan av slityteskiktet bildade skrubbytan utbredes omedelbart efter det att slityteskiktet avlägsnats frän pressformen en av en bindgummiblandning bildad lösning, för att förhindra oxidation av skrubbytan och förstärka de vid senare vulkanisering av bindgummiskiktet verkande bindkrafterna.
2. Förfarande för tillverkning av en slitytering, - ringdel eller -segment enligt patentkravet 1, kännetecknat därav, att bindkrafterna i slitytskiktets skrubbyta förstärkes, genom att forma och vulkanisera skrubbytan med en rent metallisk pressform och avskilja skrubbytan frän pressformen och pä sä sätt öppna upp molekylstrukturen i slitytskiktets skrubyyta, varvid obundna molekyler eller elektroner blir bundna under inverkan av den päbredda bindgummiblandningslösningen.
3. Förfarande för tillverkning av en slitytering, -ringdel eller -segment enligt patentkrav 1 eller 2, kännetecknat därav, att skrubyytan förses med upphöjningar med en bestämd storlek och ett av de mellanliggande fördjupningarna bestämbart avständ.
4. Förfarande enligt ett eller flera av patentkraven 1-3 för tillverkning av en slitytering, -ringdel eller -segment, kännetecknat därav, att slitytskiktets, speciellt dess skrubbytas formning och vulkanisering utföres i pressformen samtidigt.
