Nakata Engineering Extruder Head Types for Industrial Rubber Goods Nakata Engineering provides a wide range of head types especially designed to meet the needs of a variety of customer applications.

TUBE HEAD (For extruding round and square hose.) DOUBLE HEADS (For double extrusion. For example: automobile door seals.) CROSS HEAD (For extruding rubberized rollers and printers' blanket rollers. Capable of metal insert extrusion.) TRIPLE HEADS (For triple extrusion. For example: automobile weather stripping.)     L-TYPE HEAD SCREEN CHANGER This head is designed to extrude at right angles (L-Type) to the extruder screw. It is equipped with devices to adjust the extrusion rate and thickness to deliver the sheet uniformly, at internal head pressures up to 100kg/cm. For head temperature control, an electric heater is placed at the rubber exit, in addition to heat water and steam circuits. The L-Type head is an inexpensive machine for sheet manufacturing - half the price of a conventional head. Forming range: 1000m x 1 to 5mm. The vacuum screen changer is a device to remove foreign materials which may enter the rubber compounds. It is mounted on the part of the head located at the top of the extruder. The vacuum screen changer consists of a pair of breaker plates divided into upper and lower parts, which can be interchanged quickly and automatically in vacuum condition. The vacuum screen changer is an essential device to efficiently produce continuous extrusions which are not mixed with air.
