Das fertig hergestellte Rohr dreht den Zylinder 11 umgebendes Gehäuse 15 ein. sich um die Achse 10 des Austrittes des Rohres. Das 20 Dieses Gehäuse enthält eine Anordnung von Steuer-Band 2 hat einen geradlinigen Rand 21 und einen kurven, die einander ähnlich ausgebildet, aber im Rand 22, der auf der AbroUtrommel mit einer ge- Verhältnis zueinander verschoben angeordnet sind, brochenen Linie dargestellt ist. Das Band 2 läuft vor Das Ende des Leitstabs 13 wird beispielsweise von seinem Wickeln in dem Formwerkzeug 1 zwischen der Steuerkurve 16 geführt. Diese Steuerkurve 16 hat zwei Treib-Leitrollen 23 und 24 mit parallelen 25 zwei kreisbogenförmig gestaltete Abschnitte, die Achsen hindurch. Die AbroUtrommel 3 ist auf einem durch einen schräg verlaufenden Teil miteinander beweglichen Wagen 31 montiert, so daß sie sich auf verbunden sind.

For the shaping guidance of the incoming The device for winding conical screw tape are provided with rollers or balls with cylindrical intermediate parts after 15 guide rods, which along some diameter and Erzeu-Fig. 1 and 2 has a mold 1 in which the genden are distributed accordingly. Each of these guide tape 2 is formed into a tube, as well as a roll rod, such as 13, is fed into a cylindrical bore, such as 14, drum 3, from which the tape is guided to the molding tool in the wall of the cylinder 11 and protrudes into a will. The finished tube rotates the housing 15 surrounding the cylinder 11. around the axis 10 of the outlet of the pipe. The 20 This housing contains an arrangement of control tape 2 has a straight edge 21 and a curve, which are similar to each other, but in the edge 22, which are arranged on the AbroUtrommel with a shift in relation to each other, is shown as a broken line. The strip 2 runs forward. The end of the guide rod 13 is guided between the control cam 16 by its winding in the molding tool 1, for example. This control cam 16 has two drive guide rollers 23 and 24 with parallel 25 two circular arc-shaped sections, the axes through. The AbroUtrommel 3 is mounted on a carriage 31 which can be moved with one another by an inclined part, so that they are connected to one another. The outer part of the circular arc corresponds to a circular arc path, the central part of which is the cylinder with a large base in the finished tube, the point 33 on the axis 10 within the mold bevel TeU corresponds to the truncated cone, while part 1 is located. The carriage 31 moves on a base 30, the inner cylindrical part corresponding to the cylinder with a small runway 32 inclined with respect to the ground. This circular arc-shaped design to which the axis 10 is assumed to be parallel. TeUe are centered on the axis of the cylinder 11. To produce a conical tube, the following three parameters are set in a rotary movement to adjust the housing 15: the axis of the cylinder 11 is guided. The rotary movement <5, the tape feed angle in the projection on the 35 is synchronized with the movement of the AbroUtrommel 3 base surface of the device, ie the angle siert ·
