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.
