Title: Apparatus for producing helically-formed welded tube
IPC: B21C37/12
Filed: 1971-09-02
Abstract: 1311080 Producing welded tube HOESCH MASCHINENFABRIK DEUTSCHLAND AG 2 Sept 1971 [19 Sept 1970] 41049/71 Heading B3A Apparatus for producing welded tube comprises a mechanism 2 for feeding metal strip 1 to a tube former 3 which winds the strip helically to form a tube, a device for welding together adjacent edges of the strip after the tube has been formed into a tube, a cutter 8 for cutting the welded tube 4 into lengths 9, a pivotable tube carrier 7 swingable so as to vary the angle between the strip feed and the longitudinal tube axis, a receiver 14 which receives the cut-off lengths of tube from the carrier, and a conveyer 18 for conveying the cut-off lengths from the receiver. The tube diameter depends on the angle which the strip feed makes with the longitudinal tube axis and the strip width. The carrier 7, a platform 5, a boom 11 and the receiver 14 all pivot about a vertical axis 6 on rails 17, the boom being parallel to the carrier when a lock 12 is fastened. The receiver is pivoted about a vertical axis 13 to enable the receiver to swing from the boom 11, when a lock 15 is unfastened, on rails 17<SP>1</SP>. This enables the tube length 9 to be removed, using lifting beam 10, from the carrier to the conveyer, Figs. 2, 3 (not shown), irrespective of the angle between the strip feed and longitudinal tube axis. In an alternative embodiment, Fig. 4 (not shown), two receivers (140), (141) are provided to transfer the tube lengths 9 to the conveyer 18.

A film 1, Fig. 4 (not shown), bearing photographed forms 32, is also provided with coarse and fine positioning marks 45, 44 which are used in positioning the film 1 for reproducing a selected one of forms 32. Timing marks 43 are also provided for producing pulses for the control of an associated xerographic printer. Two films 1, Fig. 1 (not shown), may be used, one film being positioned while a selected form 32 is being scanned on the other film. Each film is passed between fixed guides 22, 23, 26, 27 and spring-loaded guides 24, 25. When a given form 32 is called for, the film is run at a fast speed in the appropriate direction, under control of photo-cells sensing the coarse marks 45, until the film is within three forms of the desired position, whereupon the speed of advance is reduced. A solenoid valve is used to supply compressed air to a film guide plate to provide an air-bearing for the film when running at high speed, and to connect a vacuum line to the guide plate when the film is running at the slower speed. When the desired form is reached, the outputs of the photo-cells sensing the coarse marks 45 are gated with the output from the photo-cell sensing the fine marks 44, the slow drive is disengaged, and the film is then advanced at an even slower scanning speed. At the same time, a shutter is opened below a scanning slit 2 and an image of the selected form 32 is projected on to the surface of a printing drum which rotates with a peripheral speed corresponding to the scanning speed of the film 1. The film is advanced by means of pairs of rollers such as 6, 13, Fig. 3 (not shown), rollers 6 being driven at the different speeds and in one or other direction, the desired speed and direction being selected by energizing the corresponding solenoid 19 to pinch the film between the driven roller 6 and the roller 13.
