    • A disclosure relates to an apparatus for extruding and forming blanks from a rubber or polymeric material comprising a pair of hydraulic ram operated extruders (20) having outlets connected to a common delivery conduit (26). A screw extruder (46) is also connected to the conduit (26) and a control valve (54) controls flow between the respective extruders (20) and conduit (26) such that in one position of the valve (54) one of the ram operated extruders (20) is connected to the conduit outlet delivery (26) of extrudate and the other extruder (20) is connected to the screw extruder (46) to receive a fresh charge of extrudate. A closed hydraulic circuit links the hydraulic rams (14,15) of the two ram extruders (20) whereby filling of one of the extruders causes that ram to retract and pump the hydraulic fluid therefrom to the other extruder to cause that ram to extend and thereby discharge the extrudate therein and vice versa.
    • 本公开涉及一种用于由橡胶或聚合物材料挤压和成形坯料的设备,其包括具有连接到共同输送导管(26)的出口的一对液压柱塞操作的挤出机(20)。 螺杆挤出机(46)也连接到导管(26),并且控制阀(54)控制各挤出机(20)和导管(26)之间的流动,使得在阀(54)的一个位置中的一个 (20)连接到挤出物的导管出口输送装置(26),而另一个挤出机(20)连接到螺杆挤出机(46)以接收新鲜的挤出物料。 闭合的液压回路连接两个柱塞式挤出机(20)的液压柱塞(14,15),由此填充其中一个挤出机使该柱塞回缩并将液压流体从那里泵送到另一个挤出机以使该柱塞延伸并且 从而排出其中的挤出物,反之亦然。
