KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Neuerungen in der Fabrikation von Metallrohren durch Zusammendrehen von Drähten in einer Maschine von ähnlicher Construction wie diejenigen zur Herstellung von Drahtseilen (nur mit festen Spulen) in der Weise, dafs die zusammengedrehten Drähte ein biegsames Rohr bilden und, ohne aus einander zu fallen, fest zusammenhalten. Die Neuerungen bestehen also in der Verbindung einer Reihe von Längsstreifen zur Bildung eines flexiblen Rohres durch Zusammendrehen in der Weise, dafs diejenigen Theile, welche die Aufsenweite des Rohres einmal bildeten, auch auf der ganzen Länge an der Aufsenseite bleiben und ihre Lage infolge ihres Querschnittes beibehalten, auch wenn ein Bruch in dem einen oder anderen entstehen sollte. Dazu lassen sich Streifen von mannigfachen Querschnitten benutzen, vorzugsweise aber empfiehlt sich die Anwendung der Formen, welche in Fig. 1 und 2 dargestellt sind. Fig. 3 ist eine äufsere Ansicht von Fig. 2.The invention relates to innovations in the manufacture of metal pipes by Twisting wires together in a machine of similar construction to those used for Manufacture of wire ropes (only with fixed spools) in such a way that they twisted together The wires form a flexible tube and hold tightly together without falling apart. The innovations consist in the connection of a number of longitudinal strips to form a flexible tube by twisting them together in such a way that those parts which are the outer width of the pipe once formed, also remain on the outside along the entire length and as a result of their position Maintain their cross-section, even if a break occurs in one or the other should. For this purpose, strips of various cross-sections can be used, preferably however, the use of the forms shown in FIGS. 1 and 2 is recommended. FIG. 3 is an external view of FIG. 2.
Um derartige Rohre luft- und wasserdicht zu machen, giebt man ihnen innen oder aufsen einen Ueberzug von passendem Material.In order to make such pipes airtight and watertight, they are given inside or outside a covering of suitable material.
