Method and device for manufacturing a corrugated pipe by spirally winding a corrugated thin strip, preferably a steel tape.

摘要

THE invention discloses a method ESTABLISHMENT OF A PIPE WAVY THROUGH COIL SHAPED BOLT OF A THIN AND waveband, ESPECIALLY A TAPE STEEL IN WHICH AT LEAST ONE WAVE BAND ATTACHED IS INCLUDED IN A WAVE COIL playback tape above and in at least one WAVE IS ON ANOTHER WAVE COIL JOINED WITH ANOTHER tape PRESSING together. TO GET EASILY AND WITHOUT ESTABLISHING great cost TUBE WAVY FLEXIBLE AND gastight FIRST will tilt slightly to the outside WAVE CRUSHED TAPE IN MOTION IN THE CROSS-shaped section PISON WITH POWER WAVE, APPROXIMATE TO flank ONDA DEFORMED PREVIOUSLY, Formara FINALLY THE PLANE WAVE COIL TAPE upon each other in the cross section SHAPED OMEGA AND JOINTLY push TOP AND SIDES OF WAVES WITH WHAT THE NEIGHBORS eDGES OF THE SIDES OF ONDA BE FLAT IN DISTANCE WITH ANOTHER AND FINALLY THE EDGES OF WAVES UNDER PRESSURE AND RANGES alternate punctiform PRESSED IN CONJUNCTION WITH THE TOP OF THE WAVE.
