Abstract
An elastomeric extruding apparatus having a head, to which a plurality of extruders are coupled, and a rotatable, driven roller disposed at the front end of the head so as to form an extruding space between the roller and the head. The head is provided with a passage arrangement, through which the elastomeric materials pass, eventually opening into the extruding space. The extruding space has a uniform chamber extending from the opening of the passage arrangement and a finishing chamber communicating with the uniform chamber for shaping the elastomer into its final sectional shape.
