    • The invention provides methods and apparatus for producing a spirally wound pipe or pipe liner, and also to a web for forming a spirally wound pipe or pipe liner. One aspect of the invention provides a method and an associated machine of winding a helically wound pipe from a web (200) having transversely spaced apart connecting formations (310, 320) adapted to interlock when the web is wound in a helical path and adjacent edge portions (300a, 300b) of the web overlap one another, wherein an exterior support means (400) for the connecting formation at the terminus of the pipe being helically wound from the web is provided, and a radially outwardly directed force is applied against an inner face (220) of the web and the support means (400) to pinch connecting formations into interlocking engagement. A further aspect of the invention provides an elongated web (200) comprising a wall portion (210) bound by edge portions (300a, 300b) and adapted to form a pipe by spirally winding said web and joining adjacent said edge portions, wherein a distal end of joined edge portions (330) of the web projecting from the wall portion (210) of the web is less than a spacing distance defined by a spacer rib (350) projecting from the wall portion, when the web is spirally wound and adjacent edge portions are joined together.
    • 本发明提供了用于生产螺旋缠绕管或管衬的方法和装置,还提供了用于形成螺旋缠绕管或管衬的腹板。 本发明的一个方面提供了一种从具有横向间隔开的连接结构(310,320)的腹板(200)缠绕螺旋缠绕的管道的方法和相关联的机器,所述连接结构适于当所述腹板卷绕在螺旋路径中并且相邻边缘 纤维网的部分(300a,300b)彼此重叠,其中用于连接结构的外部支撑装置(400)在管的末端被从腹板螺旋地卷绕,并且径向向外的力被施加到 腹板的内表面(220)和支撑装置(400)将连接结构夹紧成互锁接合。 本发明的另一方面提供了一种细长腹板(200),其包括由边缘部分(300a,300b)结合的壁部分(210),并且适于通过螺旋地缠绕所述腹板并且邻近所述边缘部分接合而形成管,其中远端 从腹板的壁部分(210)突出的腹板的接合边缘部分(330)的端部小于当从腹壁突出的间隔肋(350)限定的间隔距离,当腹板螺旋缠绕并相邻 边缘部分连接在一起。
