Abstract

Метод за нанасяне на протекторен материал върху външни пневматични гуми, съгласно който се екструдира слой от невулканизиран протекторен материал върху периферията на каркаса на въртяща се външна гума, характеризиращ се с това, че екструдираният протекторен материал се подава към периферията на пневматичната гума през обем от този материал, който обем е по-голям от обема на нанасяния в момента върху периферията на гумата материал. Устройство за нанасяне на протекторен материал върху пневматични гуми, включващо екструдер, глава на екструдера и стенд за външна гума, характеризиращо се с това, че главата на екструдера се състои от горен носач и долен носач, между които е монтирана направляваща плоча, а над нея е установена формуваща планка, предният ръб на която е изнесен по-близо до периферната повърхност на гумата, отколкото челото на направляващата плоча, като при това към двете страни на носачите са монтирани ляво рамо и дясно рамо, а между формуващата планка и направляващата плоча е оформен екструдерен отвор, разположен напречно на периферната повърхност на гумата. Патентните претенции са формулирани в 6 точки
