在作为一种制造方法的发展过程中，第 1次有明确记载的是 R ． B r o o m a n在 1 8 4 5年 申请的用挤出机生产固特波胶电线的专利。固特波公 司的 H．B e w l g y随后对该 挤 出机进 行了改进 ， 并于 1 8 5 1 年将它用于包覆在 D o v e r 和 C a l a i s公司之间的第 1根海底电缆的铜线上。在此后的 2 5年内， 挤出方法 1 3渐重要 ， 并且逐渐由电动操纵的挤出机迅速替代了以往的手动挤出机。初期机械操纵的柱塞式挤出机生产了成千上万公里的绝缘电线和电缆， 从而牢固地确立了挤出法用于生产电缆的地位。早期生产电缆的挤出机无论是手动的、 机械的或者液压的， 全都是柱塞式的。在这种生产过程中， 柱塞将热的古塔波胶压入到通有铜导线口模中， 古塔波胶从口模中 挤 出， 这样就包覆在铜导线上形成绝缘层。
In the process of development as a manufacturing method, the first clearly recorded patent applied by R. B. R. O. M. A. N. in 1845 for the production of Goodwave glue wires by extruders. The extruder w a s subsequently improved by H. B. E. W. g. of Guterbo and used in 1851 to coat the copper w I r e of the first submarine cable between D. v. E. R. and Cal. A. I. companies. In the next 25 years, the extrusion method 13 became more and more important, and the manual extruder was replaced by the electric extruder. In the early stage, mechanical-operated plunger extruders produced thousands of kilometers of insulated wires and cables, which firmly established the position of extrusion method in cable production. Early cable extruders, whether manual, mechanical or hydraulic, were all plunger-type. In this production process, the plunger will press the hot gutta-perot glue into the die with copper conductor, and the gutta-perot glue will be extruded from the die, thus covering the copper conductor to form an insulating layer.
