A nozzle is provided for controlling the flow of extruded material, such as e.g., rubber material, from an extrusion machine. Movable pins are positioned into the path of material flow through an internal cavity. The pins are arranged across the path of flow upstream of the extrusion die. By moving the pins in and out, the flow of material through the cavity can be controlled at different locations across the width of the path of flow to the die. Manual and automatic controls can be provided for determining the position of the pins and thereby controlling the flow.

A sizer for cooling an extrudate includes a core and a housing. The core includes an extrusion channel which accommodates the extrudate, a core cooling channel, and a core vacuum channel in fluid communication with said extrusion channel. The housing includes a housing cooling channel, a housing vacuum channel, a cooling intake, and a cooling exhaust. The housing cooling and vacuum channels having curved segments. The cooling intake and exhaust being in fluid communication with said housing cooling channel.
