Abstract
A binding rubber extruder for retreading tires is provided with an extruder head, an axis of which extends essentially vertically to a surface of a carcass. The revolving speed of the rotatably drivable carcass and the extrusion speed are adjusted relative to one another. The extruder head is provided with a nozzle, that has a radius of curvature that corresponds at least to a greatest radius of the carcass whereby the nozzle is pressable against the carcass surface with a gentle, elastic force.
Claims16
In a binding rubber extruder for retreading tires having an extruder head, an axis of which extends essentially perpendicularly to a surface of a carcass, with said carcass being supported in a rotatably drivable manner and with a revolving speed of said carcass and an extrusion speed being adjusted to one another, the improvement wherein:
- said extruder head has a nozzle with a radius of curvature in a circumferential direction of said carcass surface that corresponds at least to a greatest radius of curvature of said carcass surface in said circumferential direction;
- and
- means for pressing said nozzle against said carcass surface with a gentle, elastic force are provided, said gentle, elastic force being exerted in an essentially radial direction of said carcass.
A binding rubber extruder according to cIaim 7, in which said nozzle has a planar, rectangular cross-section.
