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 точкиA method of applying tread material to outer pneumatic tires, according to which a layer of unvulcanized tread material is extruded on the periphery of the carcass of a rotatable outer tire, characterized in that the extruded tread material is fed to the periphery of the pneumatic tire through a volume of material, the volume of which is greater than the volume of the material currently applied to the tire periphery. A device for applying tread material to pneumatic tires, comprising an extruder, an extruder head and a tire stand, characterized in that the extruder head consists of an upper support and a lower support, between which a guide plate is mounted, and above a molding plate is established, the front edge of which is brought out closer to the peripheral surface of the tire than the face of the guide plate, and a left arm and a right arm are mounted on both sides of the carriers, and between the molding plate and the guide plate is shaped extrusion opening located transversely on the peripheral surface of the tire. The patent claims are formulated in 6 points
