    • A liquid component can be introduced into a detergent bar by injecting liquid within or immediately downstream of a multi-apertured plate positioned before the compression cone of an extruder. The method can be used to produce marbled bars with the aid of a colored liquid and is described in U.K. Pat. No. 1,387,567.When a double extruder is used together with a common compression cone the injected liquid becomes unevenly distributed within the detergent. Even distribution of the liquid as striations is achieved by use of a partition in the cone to ensure each detergent stream is subjected to separate compression during movement down the cone. The partition extends to the final extrusion plate; the velocities of the two streams are equalized by having a common extrusion volume between after the two screw extruders.
    • 液体组分可以通过在位于挤压机的压缩锥体之前的多孔板内或紧邻下游喷射液体而被引入到洗涤剂棒中。 该方法可用于在有色液体的帮助下制备大理石条,并在英国专利No. 第1,387,567号。 当双挤出机与共同的压缩锥体一起使用时,注射的液体变得不均匀地分布在洗涤剂内。 作为条纹的液体的均匀分布通过使用锥体中的分隔体来实现,以确保每个洗涤剂流在锥体移动期间经受单独的压缩。 隔板延伸到最终的挤压板; 通过在两个螺杆挤出机之后具有相同的挤出体积来平衡两个流的速度。
