    摘要： A thin-walled, flexible and collapse-resistant thermo-plastic tubing has a substantially smooth bore and a helical outer support bead structure. The tubing includes at least one conductor helically disposed within the support bead structure. The tubing comprises a flexible tubing wall formed of a thermoplastic ribbon, the ribbon while molten being helically wrapped repeatedly on itself to overlap a certain amount forming a helical lap joint where successive wraps of the ribbon heat-bond integrally to one another so that an elongate tubular body is formed. The tubing comprises a plateau portion on the flexible tubing wall and defining at least one elongate groove, which converges in a radially outward direction to open radially on the plateau portion. At least one elongate conductor is disposed in one or more grooves of the at least one elongate groove and helically around and along the elongate tubular body. An elongate thermoplastic support bead is disposed helically around and along the elongate tubular body on the plateau portion, the support bead and the plateau portion cooperatively forming the bead structure.

    摘要： Verfahren zur Herstellung eines Wickelschlauches aus thermoplastischem Kunststoff. Zumindest ein Kunststoffstreifen wird auf einem zylinderförmigen Wickelkern wendelförmig zu dem Wickelschlauch kontinuierlich gewickelt, wobei Längskantenabschnitte benachbarter Wendelwicklungen des Kunststoffstreifens überlappend miteinander verbunden werden. Die Längskantenabschnitte werden durch Einbringen eines schmelzflüssigen Zusatzkunststoffes zwischen einander zugeordneten Längskantenabschnitten stoffschlüssig miteinander verschweißt. Die Wickelkernoberfläche ist mit der Maßgabe eingerichtet, dass der den Wickelkern umschlingende Kunststoffstreifen in reibschlüssigen Kontakt mit der Wickelkernoberfläche kommt.

    摘要： A composite strip (10) windable to form a helical pipe is disclosed. The composite strip (10) comprises: an elongate plastic strip (11) having a base portion (12) and at least one lengthwise extending rib portion (20) upstanding from the base portion (12); and an elongate reinforcing strip (30) extending lengthwise and supported laterally by the rib portion (20), the reinforcing strip (30) having a height to thickness ratio of at least three to one and orientated substantially perpendicular to the base portion (12). When wound into a helical pipe, the reinforcing strip (30) reinforces the pipe against radial crushing loads. A bead (40) seals the reinforcing strip (30) from the environment. Desirably the composite strip (10) further comprises: a planar lamina (50) extending lengthwise and bonded to the base portion (12), the lamina (50) having a higher Young’s modulus and strength than those of the plastic strip (11). The lamina (50) greatly improves the pressure rating of a pipe wound from the strip (10).
