Abstract
An injector head for producing tread strips, and including a thickness-adjusting slide and two side plates for forming an essentially trapezoidal tread strip profile. The side plates are mounted so as to be adjustable in a lateral direction, and are supported against the thickness-adjusting slide in a direction parallel to the direction of extrusion. The thickness-adjusting slide extends on the shorter side of the trapezoid over the entire width of the tread strip. Either the thickness-adjusting slide or the side plates are mounted on an injector head end member that can swivel away.
